# cubrid_prepare

(PECL CUBRID >= 8.3.0)

cubrid_prepare — Prepare a SQL statement for execution

### 説明

resource cubrid_prepare ( resource `$conn_identifier` , string `$prepare_stmt` [, int `$option` = 0 ] )

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.

### パラメータ

`conn_identifier`

  Connection identifier.

`prepare_stmt`

  Prepare query.

`option`

  OID return option CUBRID_INCLUDE_OID.

### 返り値

Request identifier, if process is successful;

`FALSE`, if process is unsuccessful.

### 例

例1 cubrid_prepare() 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:\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);
?>`

上の例の出力は以下となります。

    There are 27 event that exits in 2004 olympic but not in 2000. For example:

    Event_code      Event_name
    ----------------------------
    20063           +91kg
    20070           64kg
