public interface ResultSet extends Wrapper, AutoCloseable
A table of data representing a database result set, which is usually generated by executing a statement that queries the database.

A `ResultSet` object maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The `next` method moves the cursor to the next row, and because it returns `false` when there are no more rows in the `ResultSet` object, it can be used in a `while` loop to iterate through the result set.

A default `ResultSet` object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produce `ResultSet` objects that are scrollable and/or updatable. The following code fragment, in which `con` is a valid `Connection` object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. See `ResultSet` fields for other options.

           Statement stmt = con.createStatement(
                                          ResultSet.TYPE_SCROLL_INSENSITIVE,
                                          ResultSet.CONCUR_UPDATABLE);
           ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
           // rs will be scrollable, will not show changes made by others,
           // and will be updatable

The `ResultSet` interface provides getter methods (`getBoolean`, `getLong`, and so on) for retrieving column values from the current row. Values can be retrieved using either the index number of the column or the name of the column. In general, using the column index will be more efficient. Columns are numbered from 1. For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once.

For the getter methods, a JDBC driver attempts to convert the underlying data to the Java type specified in the getter method and returns a suitable Java value. The JDBC specification has a table showing the allowable mappings from SQL types to Java types that can be used by the `ResultSet` getter methods.

Column names used as input to getter methods are case insensitive. When a getter method is called with a column name and several columns have the same name, the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL query that generated the result set. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names are used, the programmer should take care to guarantee that they uniquely refer to the intended columns, which can be assured with the SQL AS clause.

A set of updater methods were added to this interface in the JDBC 2.0 API (Java 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getter methods also apply to parameters to the updater methods.

The updater methods may be used in two ways:

1. to update a column value in the current row. In a scrollable `ResultSet` object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates the `NAME` column in the fifth row of the `ResultSet` object `rs` and then uses the method `updateRow` to update the data source table from which `rs` was derived.

              rs.absolute(5); // moves the cursor to the fifth row of rs
              rs.updateString("NAME", "AINSWORTH"); // updates the
                 // NAME column of row 5 to be AINSWORTH
              rs.updateRow(); // updates the row in the data source

2. to insert column values into the insert row. An updatable `ResultSet` object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it into `rs` and into the data source table using the method `insertRow`.

              rs.moveToInsertRow(); // moves cursor to the insert row
              rs.updateString(1, "AINSWORTH"); // updates the
                 // first column of the insert row to be AINSWORTH
              rs.updateInt(2,35); // updates the second column to be 35
              rs.updateBoolean(3, true); // updates the third column to true
              rs.insertRow();
              rs.moveToCurrentRow();

A `ResultSet` object is automatically closed when the `Statement` object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.

The number, types and properties of a `ResultSet` object's columns are provided by the `ResultSetMetaData` object returned by the `ResultSet.getMetaData` method.

## Method Details

### next

boolean next() throws SQLException
Moves the cursor forward one row from its current position. A `ResultSet` cursor is initially positioned before the first row; the first call to the method `next` makes the first row the current row; the second call makes the second row the current row, and so on.

When a call to the `next` method returns `false`, the cursor is positioned after the last row. Any invocation of a `ResultSet` method which requires a current row will result in a `SQLException` being thrown. If the result set type is `TYPE_FORWARD_ONLY`, it is vendor specified whether their JDBC driver implementation will return `false` or throw an `SQLException` on a subsequent call to `next`.

If an input stream is open for the current row, a call to the method `next` will implicitly close it. A `ResultSet` object's warning chain is cleared when a new row is read.

Returns:
  `true` if the new current row is valid; `false` if there are no more rows
Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed result set

### close

void close() throws SQLException
Releases this `ResultSet` object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

The closing of a `ResultSet` object does not close the `Blob`, `Clob` or `NClob` objects created by the `ResultSet`. `Blob`, `Clob` or `NClob` objects remain valid for at least the duration of the transaction in which they are created, unless their `free` method is invoked.

When a `ResultSet` is closed, any `ResultSetMetaData` instances that were created by calling the `getMetaData` method remain accessible.

Note: A `ResultSet` object is automatically closed by the `Statement` object that generated it when that `Statement` object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.

Calling the method `close` on a `ResultSet` object that is already closed is a no-op.

Specified by:
  `close` in interface `AutoCloseable`
Throws:
  `SQLException` - if a database access error occurs

### wasNull

boolean wasNull() throws SQLException
Reports whether the last column read had a value of SQL `NULL`. Note that you must first call one of the getter methods on a column to try to read its value and then call the method `wasNull` to see if the value read was SQL `NULL`.

Returns:
  `true` if the last column value read was SQL `NULL` and `false` otherwise

Retrieves the first warning reported by calls on this `ResultSet` object. Subsequent warnings on this `ResultSet` object will be chained to the `SQLWarning` object that this method returns.

The warning chain is automatically cleared each time a new row is read. This method may not be called on a `ResultSet` object that has been closed; doing so will cause an `SQLException` to be thrown.

Note: This warning chain only covers warnings caused by `ResultSet` methods. Any warning caused by `Statement` methods (such as reading OUT parameters) will be chained on the `Statement` object.

Returns:
  the first `SQLWarning` object reported or `null` if there are none
Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed result set

### clearWarnings

void clearWarnings() throws SQLException
Clears all warnings reported on this `ResultSet` object. After this method is called, the method `getWarnings` returns `null` until a new warning is reported for this `ResultSet` object.

Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed result set

### getCursorName

String getCursorName() throws SQLException
Retrieves the name of the SQL cursor used by this `ResultSet` object.

In SQL, a result table is retrieved through a cursor that is named. The current row of a result set can be updated or deleted using a positioned update/delete statement that references the cursor name. To insure that the cursor has the proper isolation level to support update, the cursor's `SELECT` statement should be of the form `SELECT FOR UPDATE`. If `FOR UPDATE` is omitted, the positioned updates may fail.

The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a `ResultSet` object. The current row of a `ResultSet` object is also the current row of this SQL cursor.

Returns:
  the SQL name for this `ResultSet` object's cursor
Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed result set
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method

### getMetaData

ResultSetMetaData getMetaData() throws SQLException
Retrieves the number, types and properties of this `ResultSet` object's columns.

Returns:
  the description of this `ResultSet` object's columns
Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed result set

### getObject

Object getObject(int columnIndex) throws SQLException

Gets the value of the designated column in the current row of this `ResultSet` object as an `Object` in the Java programming language.

This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL `NULL`, the driver returns a Java `null`.

This method may also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of method `getObject` is extended to materialize data of SQL user-defined types.

If `Connection.getTypeMap` does not throw a `SQLFeatureNotSupportedException`, then when a column contains a structured or distinct value, the behavior of this method is as if it were a call to: `getObject(columnIndex, this.getStatement().getConnection().getTypeMap())`. If `Connection.getTypeMap` does throw a `SQLFeatureNotSupportedException`, then structured values are not supported, and distinct values are mapped to the default Java class as determined by the underlying SQL type of the DISTINCT type.

Parameters:
  `columnIndex` - the first column is 1, the second is 2, ...
Returns:
  a `java.lang.Object` holding the column value
Throws:
  `SQLException` - if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set

### getObject

Object getObject(String columnLabel) throws SQLException

Gets the value of the designated column in the current row of this `ResultSet` object as an `Object` in the Java programming language.

This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL `NULL`, the driver returns a Java `null`.

This method may also be used to read database-specific abstract data types.

In the JDBC 2.0 API, the behavior of the method `getObject` is extended to materialize data of SQL user-defined types. When a column contains a structured or distinct value, the behavior of this method is as if it were a call to: `getObject(columnIndex, this.getStatement().getConnection().getTypeMap())`.

Parameters:
  `columnLabel` - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column

Note: Support for the `isLast` method is optional for `ResultSet`s with a result set type of `TYPE_FORWARD_ONLY`

Returns:
  `true` if the cursor is on the last row; `false` otherwise
Throws:
  `SQLException` - if a database access error occurs or this method is called on a closed result set

### absolute

boolean absolute(int row) throws SQLException
Moves the cursor to the given row number in this `ResultSet` object.

If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.

If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method `absolute(-1)` positions the cursor on the last row; calling the method `absolute(-2)` moves the cursor to the next-to-last row, and so on.

If the row number specified is zero, the cursor is moved to before the first row.

An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.

Note: Calling `absolute(1)` is the same as calling `first()`. Calling `absolute(-1)` is the same as calling `last()`.

Parameters:
  `row` - the number of the row to which the cursor should move. A value of zero indicates that the cursor will be positioned before the first row; a positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set
Returns:
  `true` if the cursor is moved to a position in this `ResultSet` object; `false` if the cursor is before the first row or after the last row
Throws:
  `SQLException` - if a database access error occurs; this method is called on a closed result set or the result set type is `TYPE_FORWARD_ONLY`
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
Since:
  1.2

### relative

boolean relative(int rows) throws SQLException
Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Calling `relative(0)` is valid, but does not change the cursor position.

Note: Calling the method `relative(1)` is identical to calling the method `next()` and calling the method `relative(-1)` is identical to calling the method `previous()`.

Parameters:
  `rows` - an `int` specifying the number of rows to move from the current row; a positive number moves the cursor forward; a negative number moves the cursor backward
Returns:
  `true` if the cursor is on a row; `false` otherwise
Throws:
  `SQLException` - if a database access error occurs; this method is called on a closed result set or the result set type is `TYPE_FORWARD_ONLY`
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
Since:
  1.2

### previous

boolean previous() throws SQLException
Moves the cursor to the previous row in this `ResultSet` object.

When a call to the `previous` method returns `false`, the cursor is positioned before the first row. Any invocation of a `ResultSet` method which requires a current row will result in a `SQLException` being thrown.

If an input stream is open for the current row, a call to the method `previous` will implicitly close it. A `ResultSet` object's warning change is cleared when a new row is read.

Returns:
  `true` if the cursor is now positioned on a valid row; `false` if the cursor is positioned before the first row
Throws:
  `SQLException` - if a database access error occurs; this method is called on a closed result set or the result set type is `TYPE_FORWARD_ONLY`

### refreshRow

void refreshRow() throws SQLException
Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.

The `refreshRow` method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call `refreshRow` when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one.

All values are refetched subject to the transaction isolation level and cursor sensitivity. If `refreshRow` is called after calling an updater method, but before calling the method `updateRow`, then the updates made to the row are lost. Calling the method `refreshRow` frequently will likely slow performance.

Throws:
  `SQLException` - if a database access error occurs; this method is called on a closed result set; the result set type is `TYPE_FORWARD_ONLY` or if this method is called when the cursor is on the insert row
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method or this method is not supported for the specified result set type and result set concurrency.

If no updates have been made or `updateRow` has already been called, this method has no effect.

Throws:
  `SQLException` - if a database access error occurs; this method is called on a closed result set; the result set concurrency is `CONCUR_READ_ONLY` or if this method is called when the cursor is on the insert row
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
Since:
  1.2

### moveToInsertRow

void moveToInsertRow() throws SQLException
Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updater methods prior to inserting the row into the result set. Only the updater, getter, and `insertRow` methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling `insertRow`. An updater method must be called before a getter method can be called on a column value.

Throws:
  `SQLException` - if a database access error occurs; this method is called on a closed result set or the result set concurrency is `CONCUR_READ_ONLY`
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method

  1.7

### updateObject

default void updateObject(int columnIndex, Object x, SQLType targetSqlType, int scaleOrLength) throws SQLException
Updates the designated column with an `Object` value. The updater methods are used to update column values in the current row or the insert row. The updater methods do not update the underlying database; instead the `updateRow` or `insertRow` methods are called to update the database.

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 statement is executed.

The default implementation will throw `SQLFeatureNotSupportedException`

Parameters:
  `columnIndex` - the first column is 1, the second is 2, ...
  `x` - the new column value
  `targetSqlType` - the SQL type to be sent to the database
  `scaleOrLength` - for an object of `java.math.BigDecimal` , 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 the columnIndex is not valid; if a database access error occurs; the result set concurrency is `CONCUR_READ_ONLY` or this method is called on a closed result set
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method; if the JDBC driver does not support the specified targetSqlType

Updates the designated column with an `Object` value. The updater methods are used to update column values in the current row or the insert row. The updater methods do not update the underlying database; instead the `updateRow` or `insertRow` methods are called to update the database.

If the second argument is an `InputStream` then the stream must contain 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 statement is executed.

The default implementation will throw `SQLFeatureNotSupportedException`

Parameters:
  `columnLabel` - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
  `x` - the new column value
  `targetSqlType` - the SQL type to be sent to the database
  `scaleOrLength` - for an object of `java.math.BigDecimal` , 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 the columnLabel is not valid; if a database access error occurs; the result set concurrency is `CONCUR_READ_ONLY` or this method is called on a closed result set
  `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method; if the JDBC driver does not support the specified targetSqlType
