cubrid_lob2_seek
resource$lob_identifier,
int$offset,
[int$origin = CUBRID_CURSOR_CURRENT]
): bool
The cubrid_lob2_seek 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.
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.
Parameters
- lob_identifier
-
Lob identifier as a result of cubrid_lob2_new or get from the result set.
- offset
-
Number of units you want to move the cursor.
- origin
-
This parameter can be the following values:
CUBRID_CURSOR_FIRST: move forward from the first beginning.
CUBRID_CURSOR_CURRENT: move forward or backward from the current position.
CUBRID_CURSOR_LAST: move backward at the end of LOB object.
Return Values
Returns true on success or false on failure.
