fbsql_read_clob
(PHP 4 = 4.2.0)
Description
Returns: A string containing the CLOB specified by clob_handle.
fbsql_read_clob() reads CLOB data from the database. If a select statement contains BLOB and/or CLOB columns FrontBase will return the data directly when data is fetched. This default behavior can be changed with fbsql_set_lob_mode() so the fetch functions will return handles to BLOB and CLOB data. If a handle is fetched a user must call fbsql_read_clob() to get the actual CLOB data from the database.
瞰赽 1. fbsql_read_clob() example
?php $link = fbsql_pconnect ("localhost", "_SYSTEM", "secret") or die ("Could not connect"); $sql = "SELECT CLOB_COLUMN FROM CLOB_TABLE;"; $rs = fbsql_query($sql, $link); $row_data = fbsql_fetch_row($rs); // $row_data[0] will now contain the clob data for teh first row fbsql_free_result($rs); $rs = fbsql_query($sql, $link); fbsql_set_lob_mode($rs, FBSQL_LOB_HANDLE); $row_data = fbsql_fetch_row($rs); // $row_data[0] will now contain a handle to the CLOB data in the first row $clob_data = fbsql_read_clob($row_data[0]); fbsql_free_result($rs);?
