odbc_prepare

(PHP 4, PHP 5)

odbc_preparePrepares a statement for execution

Описание

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.

Список параметров

connection_id

Идентификатор соединения ODBC, за подробностями обращайтесь к odbc_connect().

query_string

The query string statement being prepared.

Возвращаемые значения

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

Примеры

Пример #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).

Use this example for IBM DB/2:

$q = "update TABLE set PASS=? where NAME=?";
$res = odbc_prepare ($con, $q);

$a = "secret"; $b="user";
$exc = odbc_execute($res, array($a, $b));

Is it just me or is the code above misleading? It makes it look like odbc_execute() returns a resource suitable, say, for passing to one of the odbc_fetch_* functions.

In fact, odbc_execute() returns a boolean, which simply indicates success (TRUE) or failure (FALSE). The variable to pass to odbc_fetch_* is the same one that you pass to odbc_execute():

<?php
$res 
odbc_prepare($db_conn$query_string);
if(!
$res) die("could not prepare statement ".$query_string);

if(
odbc_execute($res$parameters)) {
   
$row odbc_fetch_array($res);
} else {
   
// handle error
}
?>

odbc_exec() returns BOOLEAN if the query doesn't return a result set.

If the query returns a result set, odbc_exec() returns a resource to that result set.
