Cursor Without Hold

The COMMIT or SYNCPOINT commands will close all opened cursors when they are executed. While declaring the cursor, the WITH HOLD option is used to avoid the above issue.

The cursor will close automatically if the WITH HOLD option is not coded. These cursors are called cursors WITHOUT HOLD. WITHOUT HOLD option is the default, and there is no need to code explicitly.

Syntax -

EXEC SQL
	DECLARE cursor-name [WITHOUT HOLD]
	    CURSOR FOR 
		select-statement
END-EXEC.

WITHOUT HOLD -

• Specifies the cursor can close when the COMMIT or SYNCPOINT executed.
