db2_prepare

(PECL ibm_db2 >= 1.0.0)

db2_prepare Prepares an SQL statement to be executed

Açıklama

resource db2_prepare ( resource $connection , string $statement [, array $options ] )

db2_prepare() creates a prepared SQL statement which can include 0 or more parameter markers (? characters) representing parameters for input, output, or input/output. You can pass parameters to the prepared statement using db2_bind_param(), or for input values only, as an array passed to db2_execute().

There are three main advantages to using prepared statements in your application:

Değiştirgeler

connection

A valid database connection resource variable as returned from db2_connect() or db2_pconnect().

statement

An SQL statement, optionally containing one or more parameter markers..

options

An associative array containing statement options. You can use this parameter to request a scrollable cursor on database servers that support this functionality.

For a description of valid statement options, see db2_set_option().

Dönen Değerler

Returns a statement resource if the SQL statement was successfully parsed and prepared by the database server. Returns FALSE if the database server returned an error. You can determine which error was returned by calling db2_stmt_error() or db2_stmt_errormsg().

Örnekler

Örnek 1 Preparing and executing an SQL statement with parameter markers

The following example prepares an INSERT statement that accepts four parameter markers, then iterates over an array of arrays containing the input values to be passed to db2_execute().

<?php
$animals 
= array(
    array(
0'cat''Pook'3.2),
    array(
1'dog''Peaches'12.3),
    array(
2'horse''Smarty'350.0),
);

$insert 'INSERT INTO animals (id, breed, name, weight)
    VALUES (?, ?, ?, ?)'
;
$stmt db2_prepare($conn$insert);
if (
$stmt) {
    foreach (
$animals as $animal) {
        
$result db2_execute($stmt$animal);
    }
}
?>
