sqlsrv_prepare - Prepares a query for execution

Manual

sqlsrv_prepare( resource$conn, string$sql, [array$params], [array$options] ): mixed

Prepares a query for execution. This function is ideal for preparing a query that will be executed multiple times with different parameter values.

Parameters

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.

Return Values

Returns a statement resource on success and false if an error occurred.

Notes

When you prepare a statement that uses variables as parameters, the variables are bound to the statement. This means that if you update the values of the variables, the next time you execute the statement it will run with updated parameter values. For statements that you plan to execute only once, use sqlsrv_query.
