CUBRID_PREPARE(3) 1 CUBRID_PREPARE(3)
cubrid_prepare - Prepare a SQL statement for execution
SYNOPSIS
resource cubrid_prepare (resource $conn_identifier, string $prepare_stmt, [int $option])
DESCRIPTION
The cubrid_prepare(3) 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(3).
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(3) function only.
PARAMETERS
o $conn_identifier
-Connection identifier.
o $prepare_stmt
-Prepare query.
o $option
-OID return option CUBRID_INCLUDE_OID.
RETURN VALUES
Request identifier, if process is successful;
FALSE, if process is unsuccessful.
EXAMPLES
Example #1
cubrid_prepare(3) example
<?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:
", $row_num);
printf("%-15s %s
", "Event_code", "Event_name");
printf("----------------------------
");
$row = cubrid_fetch_assoc($req);
printf("%-15d %s
", $row["event_code"], $row["name"]);
$row = cubrid_fetch_assoc($req);
printf("%-15d %s
", $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
