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'".
