odbc_prepare Prepares a statement for execution


odbc_prepare

(PHP 4, PHP 5)

odbc_preparePrepares a statement for execution

说明

resource odbc_prepare ( resource $connection_id , string $query_string )

Prepares a statement for execution. The result identifier can be used later to execute the statement with odbc_execute().

Some databases (such as IBM DB2, MS SQL Server, and Oracle) support stored procedures that accept parameters of type IN, INOUT, and OUT as defined by the ODBC specification. However, the Unified ODBC driver currently only supports parameters of type IN to stored procedures.

参数

connection_id

ODBC 连接标识符,详见 odbc_connect()

query_string

The query string statement being prepared.

返回值

Returns an ODBC result identifier if the SQL command was prepared successfully. Returns FALSE on error.

范例

Example #1 odbc_execute() and odbc_prepare() example

In the following code, $success will only be TRUE if all three parameters to myproc are IN parameters:

<?php
$a 
1;
$b 2;
$c 3;
$stmt    odbc_prepare($conn'CALL myproc(?,?,?)');
$success odbc_execute($stmt, array($a$b$c));
?>

If you need to call a stored procedure using INOUT or OUT parameters, the recommended workaround is to use a native extension for your database (for example, mssql for MS SQL Server, or oci8 for Oracle).
