# Interface RowSet

All Superinterfaces:
  `AutoCloseable`, `ResultSet`, `Wrapper`

All Known Subinterfaces:
  `CachedRowSet`, `FilteredRowSet`, `JdbcRowSet`, `JoinRowSet`, `SyncResolver`, `WebRowSet`

public interface RowSet extends ResultSet
The interface that adds support to the JDBC API for the JavaBeans component model. A rowset, which can be used as a JavaBeans component in a visual Bean development environment, can be created and configured at design time and executed at run time.

The `RowSet` interface provides a set of JavaBeans properties that allow a `RowSet` instance to be configured to connect to a JDBC data source and read some data from the data source. A group of setter methods (`setInt`, `setBytes`, `setString`, and so on) provide a way to pass input parameters to a rowset's command property. This command is the SQL query the rowset uses when it gets its data from a relational database, which is generally the case.

The `RowSet` interface supports JavaBeans events, allowing other components in an application to be notified when an event occurs on a rowset, such as a change in its value.

The `RowSet` interface is unique in that it is intended to be implemented using the rest of the JDBC API. In other words, a `RowSet` implementation is a layer of software that executes "on top" of a JDBC driver. Implementations of the `RowSet` interface can be provided by anyone, including JDBC driver vendors who want to provide a `RowSet` implementation as part of their JDBC products.

A `RowSet` object may make a connection with a data source and maintain that connection throughout its life cycle, in which case it is called a connected rowset. A rowset may also make a connection with a data source, get data from it, and then close the connection. Such a rowset is called a disconnected rowset. A disconnected rowset may make changes to its data while it is disconnected and then send the changes back to the original source of the data, but it must reestablish a connection to do so.

A disconnected rowset may have a `Reader` (a `RowSetReader` object) and a writer (a `RowSetWriter` object) associated with it. The `Reader` may be implemented in many different ways to populate a rowset with data, including getting data from a non-relational data source. The writer can also be implemented in many different ways to propagate changes made to the rowset's data back to the underlying data source.

Rowsets are easy to use. The `RowSet` interface extends the standard `java.sql.ResultSet` interface. The `RowSetMetaData` interface extends the `java.sql.ResultSetMetaData` interface. Thus, developers familiar with the JDBC API will have to learn a minimal number of new APIs to use rowsets. In addition, third-party software tools that work with JDBC `ResultSet` objects will also easily be made to work with rowsets.

### setNull

void setNull(int paramIndex, int sqlType, String typeName) throws SQLException
Sets the designated parameter in this `RowSet` object's SQL command to SQL `NULL`. This version of the method `setNull` should be used for SQL user-defined types (UDTs) and `REF` type parameters. Examples of UDTs include: `STRUCT`, `DISTINCT`, `JAVA_OBJECT`, and named array types.

Note: To be portable, applications must give the SQL type code and the fully qualified SQL type name when specifying a NULL UDT or `REF` parameter. In the case of a UDT, the name is the type name of the parameter itself. For a `REF` parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for UDT and `REF` parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or `REF` type, the typeName parameter is ignored.

Parameters:
  `paramIndex` - the first parameter is 1, the second is 2, ...
  `sqlType` - a value from `java.sql.Types`
  `typeName` - the fully qualified name of an SQL UDT or the type name of the SQL structured type being referenced by a `REF` type; ignored if the parameter is not a UDT or `REF` type
Throws:

### setNull

void setNull(String parameterName, int sqlType, String typeName) throws SQLException
Sets the designated parameter to SQL `NULL`. This version of the method `setNull` should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

Parameters:
  `parameterName` - the name of the parameter
  `sqlType` - a value from `java.sql.Types`
  `typeName` - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or SQL `REF` value

### setObject

void setObject(int parameterIndex, Object x, int targetSqlType, int scaleOrLength) throws SQLException
Sets the designated parameter in this `RowSet` object's command with the given Java `Object`. For integral values, the `java.lang` equivalent objects should be used (for example, an instance of the class `Integer` for an `int`). If the second argument is an `InputStream` then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a `Reader` then the `Reader` must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a `SQLException` when the prepared statement is executed.

The given Java object will be converted to the targetSqlType before being sent to the database.

If the object is of a class implementing `SQLData`, the rowset should call the method `SQLData.writeSQL` to write the object to an `SQLOutput` data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `NClob`, `Struct`, `java.net.URL`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database-specific abstract data types.

Parameters:
  `parameterIndex` - the first parameter is 1, the second is 2, ...
  `x` - the object containing the input parameter value
  `targetSqlType` - the SQL type (as defined in `java.sql.Types`) to be sent to the database. The scale argument may further qualify this type.
  `scaleOrLength` - for `java.sql.Types.DECIMAL` or `java.sql.Types.NUMERIC types`, this is the number of digits after the decimal point. For Java Object types `InputStream` and `Reader`, this is the length of the data in the stream or `Reader`. For all other types, this value will be ignored.
Throws:
  `SQLException` - if a database access error occurs
See Also:
  - `Types`

### setObject

void setObject(String parameterName, Object x, int targetSqlType, int scale) throws SQLException
Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the `java.lang` equivalent objects should be used.

The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface `SQLData`), the JDBC driver should call the method `SQLData.writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `NClob`, `Struct`, `java.net.URL`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database- specific abstract data types.

Parameters:
  `parameterName` - the name of the parameter
  `x` - the object containing the input parameter value
  `targetSqlType` - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
  `scale` - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.
Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed `CallableStatement`
  `SQLFeatureNotSupportedException` - if `targetSqlType` is a `ARRAY`, `BLOB`, `CLOB`, `DATALINK`, `JAVA_OBJECT`, `NCHAR`, `NCLOB`, `NVARCHAR`, `LONGNVARCHAR`, `REF`, `ROWID`, `SQLXML` or `STRUCT` data type and the JDBC driver does not support this data type

### setObject

void setObject(int parameterIndex, Object x, int targetSqlType) throws SQLException
Sets the designated parameter in this `RowSet` object's command with a Java `Object`. For integral values, the `java.lang` equivalent objects should be used. This method is like `setObject` above, but the scale used is the scale of the second parameter. Scalar values have a scale of zero. Literal values have the scale present in the literal.

Even though it is supported, it is not recommended that this method be called with floating point input values.

Parameters:
  `parameterIndex` - the first parameter is 1, the second is 2, ...
  `x` - the object containing the input parameter value
  `targetSqlType` - the SQL type (as defined in `java.sql.Types`) to be sent to the database
Throws:
  `SQLException` - if a database access error occurs

### setObject

void setObject(String parameterName, Object x, int targetSqlType) throws SQLException
Sets the value of the designated parameter with the given object. This method is like the method `setObject` above, except that it assumes a scale of zero.

Parameters:
  `parameterName` - the name of the parameter
  `x` - the object containing the input parameter value
  `targetSqlType` - the SQL type (as defined in java.sql.Types) to be sent to the database
Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed `CallableStatement`
  `SQLFeatureNotSupportedException` - if `targetSqlType` is a `ARRAY`, `BLOB`, `CLOB`, `DATALINK`, `JAVA_OBJECT`, `NCHAR`, `NCLOB`, `NVARCHAR`, `LONGNVARCHAR`, `REF`, `ROWID`, `SQLXML` or `STRUCT` data type and the JDBC driver does not support this data type
Since:
  1.4
See Also:
  - `ResultSet.getObject(int)`

### setObject

void setObject(String parameterName, Object x) throws SQLException
Sets the value of the designated parameter with the given object. The second parameter must be of type `Object`; therefore, the `java.lang` equivalent objects should be used for built-in types.

The JDBC specification specifies a standard mapping from Java `Object` types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

Note that this method may be used to pass database- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface `SQLData`, the JDBC driver should call the method `SQLData.writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `NClob`, `Struct`, `java.net.URL`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

Parameters:
  `parameterName` - the name of the parameter
  `x` - the object containing the input parameter value
Throws:
  `SQLException` - if a database access error occurs, this method is called on a closed `CallableStatement` or if the given `Object` parameter is ambiguous
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
Since:
  1.4
See Also:
  - `ResultSet.getObject(int)`

### setObject

void setObject(int parameterIndex, Object x) throws SQLException
Sets the designated parameter in this `RowSet` object's command with a Java `Object`. For integral values, the `java.lang` equivalent objects should be used.

The JDBC specification provides a standard mapping from Java Object types to SQL types. The driver will convert the given Java object to its standard SQL mapping before sending it to the database.

Note that this method may be used to pass database-specific abstract data types by using a driver-specific Java type. If the object is of a class implementing `SQLData`, the rowset should call the method `SQLData.writeSQL` to write the object to an `SQLOutput` data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `NClob`, `Struct`, `java.net.URL`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

An exception is thrown if there is an ambiguity, for example, if the object is of a class implementing more than one of these interfaces.

Parameters:
  `parameterIndex` - The first parameter is 1, the second is 2, ...
  `x` - The object containing the input parameter value
Throws:
  `SQLException` - if a database access error occurs

### setRef

  `x` - an object representing a BLOB
Throws:
  `SQLException` - if a database access error occurs

### setBlob

void setBlob(int parameterIndex, InputStream inputStream, long length) throws SQLException
Sets the designated parameter to a `InputStream` object. The `InputStream` must contain the number of characters specified by length otherwise a `SQLException` will be generated when the `PreparedStatement` is executed. This method differs from the `setBinaryStream (int, InputStream, int)` method because it informs the driver that the parameter value should be sent to the server as a `BLOB`. When the `setBinaryStream` method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a `LONGVARBINARY` or a `BLOB`

Parameters:
  `parameterIndex` - index of the first parameter is 1, the second is 2, ...
  `inputStream` - An object that contains the data to set the parameter value to.
  `length` - the number of bytes in the parameter data.
Throws:
  `SQLException` - if a database access error occurs, this method is called on a closed `PreparedStatement`, if parameterIndex does not correspond to a parameter marker in the SQL statement, if the length specified is less than zero or if the number of bytes in the `InputStream` does not match the specified length.
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
Since:
  1.6

### clearParameters

void clearParameters() throws SQLException
Clears the parameters set for this `RowSet` object's command.

In general, parameter values remain in force for repeated use of a `RowSet` object. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values, which can be done by calling the method `clearParameters`.

Throws:

### execute

void execute() throws SQLException
Fills this `RowSet` object with data.

The `execute` method may use the following properties to create a connection for reading data: url, data source name, user name, password, transaction isolation, and type map. The `execute` method may use the following properties to create a statement to execute a command: command, read only, maximum field size, maximum rows, escape processing, and query timeout.

If the required properties have not been set, an exception is thrown. If this method is successful, the current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are ignored.

If this `RowSet` object does not maintain a continuous connection with its source of data, it may use a `Reader` (a `RowSetReader` object) to fill itself with data. In this case, a `Reader` will have been registered with this `RowSet` object, and the method `execute` will call on the `Reader`'s `readData` method as part of its implementation.

Throws:
  `SQLException` - if a database access error occurs or any of the properties necessary for making a connection and creating a statement have not been set

### addRowSetListener

void addRowSetListener(RowSetListener listener)

  `parameterIndex` - of the first parameter is 1, the second is 2, ...
  `value` - the parameter value
Throws:
  `SQLException` - if the driver does not support national character sets; if the driver can detect that a data conversion error could occur ; or if a database access error occurs
Since:
  1.6

### setNString

void setNString(String parameterName, String value) throws SQLException
Sets the designated parameter to the given `String` object. The driver converts this to a SQL `NCHAR` or `NVARCHAR` or `LONGNVARCHAR`

Parameters:

  `value` - the parameter value
Throws:
  `SQLException` - if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; or if a database access error occurs
Since:
  1.6

### setNCharacterStream

void setNCharacterStream(int parameterIndex, Reader value, long length) throws SQLException
Sets the designated parameter to a `Reader` object. The `Reader` reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.

Since:
  1.6

### setNCharacterStream

void setNCharacterStream(String parameterName, Reader value, long length) throws SQLException
Sets the designated parameter to a `Reader` object. The `Reader` reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.

Parameters:
  `parameterName` - the name of the column to be set
  `value` - the parameter value
  `length` - the number of characters in the parameter data.
Throws:

### setNCharacterStream

void setNCharacterStream(String parameterName, Reader value) throws SQLException
Sets the designated parameter to a `Reader` object. The `Reader` reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setNCharacterStream` which takes a length parameter.

Parameters:
  `parameterName` - the name of the parameter
  `value` - the parameter value
Throws:
  `SQLException` - if the driver does not support national character sets; if the driver can detect that a data conversion error could occur ; if a database access error occurs; or this method is called on a closed `CallableStatement`
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
Since:
  1.6

### setNClob

void setNClob(String parameterName, NClob value) throws SQLException
Sets the designated parameter to a `java.sql.NClob` object. The object implements the `java.sql.NClob` interface. This `NClob` object maps to a SQL `NCLOB`.

Parameters:
  `parameterName` - the name of the column to be set
  `value` - the parameter value
Throws:
  `SQLException` - if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; or if a database access error occurs
Since:
  1.6

### setNClob

void setNClob(String parameterName, Reader reader, long length) throws SQLException
Sets the designated parameter to a `Reader` object. The `Reader` must contain the number of characters specified by length otherwise a `SQLException` will be generated when the `CallableStatement` is executed. This method differs from the `setCharacterStream (int, Reader, int)` method because it informs the driver that the parameter value should be sent to the server as a `NCLOB`. When the `setCharacterStream` method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a `LONGNVARCHAR` or a `NCLOB`

Parameters:
  `parameterName` - the name of the parameter to be set
  `reader` - An object that contains the data to set the parameter value to.
  `length` - the number of characters in the parameter data.
Throws:
  `SQLException` - if parameterIndex does not correspond to a parameter marker in the SQL statement; if the length specified is less than zero; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed `CallableStatement`
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
Since:
  1.6

### setNClob

void setNClob(String parameterName, Reader reader) throws SQLException
Sets the designated parameter to a `Reader` object. This method differs from the `setCharacterStream (int, Reader)` method because it informs the driver that the parameter value should be sent to the server as a `NCLOB`. When the `setCharacterStream` method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a `LONGNVARCHAR` or a `NCLOB`

Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setNClob` which takes a length parameter.

Parameters:
  `parameterName` - the name of the parameter
  `reader` - An object that contains the data to set the parameter value to.
Throws:
  `SQLException` - if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed `CallableStatement`

Since:
  1.6

### setNClob

void setNClob(int parameterIndex, Reader reader, long length) throws SQLException
Sets the designated parameter to a `Reader` object. The `Reader` must contain the number of characters specified by length otherwise a `SQLException` will be generated when the `PreparedStatement` is executed. This method differs from the `setCharacterStream (int, Reader, int)` method because it informs the driver that the parameter value should be sent to the server as a `NCLOB`. When the `setCharacterStream` method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a `LONGNVARCHAR` or a `NCLOB`

Parameters:
  `parameterIndex` - index of the first parameter is 1, the second is 2, ...
