fbsql_set_lob_mode
(PHP 4 >= 4.2.0)
fbsql_set_lob_mode -- Set the LOB retrieve mode for a FrontBase
result set
Description
bool fbsql_set_lob_mode ( resource result, string database_name)
Returns: TRUE on success, FALSE on error.
fbsql_set_lob_mode() sets the mode for retrieving LOB data
from the database. When BLOB and CLOB data is stored in
FrontBase it can be stored direct or indirect. Direct stored
LOB data will always be fetched no matter the setting of
the lob mode. If the LOB data is less than 512 bytes it
will always be stored directly.
FBSQL_LOB_DIRECT - LOB data is retrieved directly. When
data is fetched from the database with fbsql_fetch_row(),
and other fetch functions, all CLOB and BLOB columns will
be returned as ordinary columns. This is the default value
on a new FrontBase result.
FBSQL_LOB_HANDLE - LOB data is retrieved as handles to
the data. When data is fetched from the database with fbsql_fetch_row
(), and other fetch functions, LOB data will be returned
as a handle to the data if the data is stored indirect or
the data if it is stored direct. If a handle is returned
it will be a 27 byte string formatted as "@'000000000000000000000000'".
