ResultSet (Java SE 26 & JDK 26)

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

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

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

getWarnings

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

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

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

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

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

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
Returns:: a java.lang.Object holding the column value
Throws:: SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set

Note: Support for the isLast method is optional for ResultSets 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; SQLFeatureNotSupportedException - if the JDBC driver does not support this method

Note:Support for the getRow method is optional for ResultSets with a result set type of TYPE_FORWARD_ONLY

Returns:: the current row number; 0 if there is no current row
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
Since:: 1.2

absolute

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

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

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; SQLFeatureNotSupportedException - if the JDBC driver does not support this method
Since:: 1.2

setFetchDirection

void setFetchDirection(int direction) throws SQLException

Gives a hint as to the direction in which the rows in this ResultSet object will be processed. The initial value is determined by the Statement object that produced this ResultSet object. The fetch direction may be changed at any time.

refreshRow

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.
Since:: 1.2

cancelRowUpdates

Cancels the updates made to the current row in this ResultSet object. This method may be called after calling an updater method(s) and before calling the method updateRow to roll back the updates made to a row. 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

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
Since:: 1.2
