The cubrid_prepare() function is a sort of API which represents SQL statements compiled previously to a given connection handle. This pre-compiled SQL statement will be included in the cubrid_prepare().
Accordingly, you can use this statement effectively to execute several times repeatedly or to process long data. Only a single statement can be used and a parameter may put a question mark (?) to appropriate area in the SQL statement. Add a parameter when you bind a value in the VALUES clause of INSERT statement or in the WHERE clause. Note that it is allowed to bind a value to a MARK(?) by using the cubrid_bind() function only.
Connection identifier.
Prepare query.
OID return option CUBRID_INCLUDE_OID.
Request identifier, if process is successful;
FALSE
, if process is unsuccessful.
<?php $conn = cubrid_connect("localhost", 33000, "demodb"); $sql = <<<EOD SELECT g.event_code, e.name FROM game g JOIN event e ON g.event_code=e.code WHERE host_year = ? AND event_code NOT IN (SELECT event_code FROM game WHERE host_year=?) GROUP BY event_code; EOD; $req = cubrid_prepare($conn, $sql); cubrid_bind($req, 1, 2004); cubrid_bind($req, 2, 2000); cubrid_execute($req); $row_num = cubrid_num_rows($req); printf("There are %d event that exits in 2004 olympic but not in 2000. For example:\n\n", $row_num); printf("%-15s %s\n", "Event_code", "Event_name"); printf("----------------------------\n"); $row = cubrid_fetch_assoc($req); printf("%-15d %s\n", $row["event_code"], $row["name"]); $row = cubrid_fetch_assoc($req); printf("%-15d %s\n", $row["event_code"], $row["name"]); cubrid_disconnect($conn); ?>
The above example will output:
There are 27 event that exits in 2004 olympic but not in 2000. For example: Event_code Event_name ---------------------------- 20063 +91kg 20070 64kg
