cubrid_lob2_seek64 — Move the cursor of a lob object

Description

cubrid_lob2_seek64 ( resource $lob_identifier , string $offset [, int $origin = CUBRID_CURSOR_CURRENT ] ) : bool

The cubrid_lob2_seek64() function is used to move the cursor position of a lob object by the value set in the offset argument, to the direction set in the origin argument. If the offset you want to move is larger than an integer data can be stored, you can use this function.

To set the origin argument, you can use CUBRID_CURSOR_FIRST to set the cursor position moving forward offset units from the first beginning. In this case, offset must be a positive value.

If you use CUBRID_CURSOR_CURRENT for origin, you can move forward or backward. and offset can be positive or negative.

If you use CUBRID_CURSOR_LAST for origin, you can move backward offset units from the end of LOB object and offset only can be positive.

Note:

If you use this function to move the cursor position of the lob object, you should pass offset as a string.
