Parameter-Liste

conn

A connection resource returned by sqlsrv_connect().

sql

The string that defines the query to be prepared and executed.

params

An array specifying parameter information when executing a parameterized query. Array elements can be any of the following:

A literal value
A PHP variable
An array with this structure: array($value [, $direction [, $phpType [, $sqlType]]])

The following table describes the elements in the array structure above:

**Array structure**
Element	Description
$value	A literal value, a PHP variable, or a PHP by-reference variable.
$direction (optional)	One of the following SQLSRV constants used to indicate the parameter direction: SQLSRV_PARAM_IN, SQLSRV_PARAM_OUT, SQLSRV_PARAM_INOUT. The default value is SQLSRV_PARAM_IN.
$phpType (optional)	A SQLSRV_PHPTYPE_* constant that specifies PHP data type of the returned value.
$sqlType (optional)	A SQLSRV_SQLTYPE_* constant that specifies the SQL Server data type of the input value.

options

An array specifying query property options. The supported keys are described in the following table:

**Query Options**
Key	Values	Description
QueryTimeout	A positive integer value.	Sets the query timeout in seconds. By default, the driver will wait indefinitely for results.
SendStreamParamsAtExec	`true` or `false` (the default is `true`)	Configures the driver to send all stream data at execution (`true`), or to send stream data in chunks (`false`). By default, the value is set to `true`. For more information, see sqlsrv_send_stream_data().
Scrollable	SQLSRV_CURSOR_FORWARD, SQLSRV_CURSOR_STATIC, SQLSRV_CURSOR_DYNAMIC, or SQLSRV_CURSOR_KEYSET	See » Specifying a Cursor Type and Selecting Rows in the Microsoft SQLSRV documentation.

Rückgabewerte

Beispiele

Beispiel #1 sqlsrv_query() example


<?php
$serverName = "serverName\sqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password" );
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
     die( print_r( sqlsrv_errors(), true));
}

$sql = "INSERT INTO Table_1 (id, data) VALUES (?, ?)";
$params = array(1, "some data");

$stmt = sqlsrv_query( $conn, $sql, $params);
if( $stmt === false ) {
     die( print_r( sqlsrv_errors(), true));
}
?>

Anmerkungen

For statements that you plan to execute only once, use sqlsrv_query(). If you intend to re-execute a statement with different parameter values, use the combination of sqlsrv_prepare() and sqlsrv_execute().
