<function>cubrid_lob_get</function> is used to get BLOB/CLOB meta info from CUBRID database,
|
|
CUBRID gets BLOB/CLOB by executing the SQL statement, and returns all LOBs as a resource array.
|
|
Be sure that the SQL retrieves only one column and its data type is BLOB or CLOB.
|
|
</para>
|
|
<para>
|
|
Remember to use <function>cubrid_lob_close</function> to release the LOBs if you don't need it any more.
