OCI-Lob->erase -- Erases a specified portion of the internal LOB data
Description
class
OCI-Lob {
int
erase ( [int offset [, int length]] )
}
Erases a specified portion of the internal LOB data starting at a
specified offset. Parameters
length and offset are optional.
OCI-Lob->erase() erases all LOB data by default.
For BLOBs, erasing means that the existing LOB value is overwritten with
zero-bytes. For CLOBs, the existing LOB value is overwritten with spaces.
OCI-Lob->erase() returns the actual number of
characters/bytes erased or FALSE in case of error.
