sqlsrv_queryPrepares and executes a query.


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

Prepares and executes a query.

Elenco dei parametri


A connection resource returned by sqlsrv_connect().


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


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.

An array specifing 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.

Valori restituiti

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


Example #1 sqlsrv_query() example

$connectionInfo = array( "Database"=>"dbName""UID"=>"username""PWD"=>"password" );
$conn sqlsrv_connect$serverName$connectionInfo);
$conn === false ) {
print_rsqlsrv_errors(), true));

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

$stmt sqlsrv_query$conn$sql$params);
$stmt === false ) {
print_rsqlsrv_errors(), true));


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().

If you are getting an error while attempting to execute your query, and the output of sqlsrv_errors(SQLSRV_ERR_ERRORS) is this:

code: -14
message: An invalid parameter was passed to sqlsrv_query.

You have failed to pass a valid parameter to sqlsrv_query itself, which could be one of three parameters:
Connection: a valid handled for a SQL Server Connection
Query: a valid string containing your query, with placeholders for parameters:"(?)"
Parameters: An Array containing the values for your query parameters.  (optional, but much match the number of placeholders in your Query.

I could not find any information about this error, and it turned out to be a missing connection parameter. In my case I found I had typed "$connn" instead of "$conn" in the code:
if ($stmt=sqlsrv_query($conn, $sql, $params)) { ...

While this seems like a total "noobie" thing to do, the fact of the matter is there is very little information about this SQL Server Error message itself. So, the plain meaning of SQLSTATE "IMSSP", CODE "-14" is that you provided no valid connection object to your sqlsrv_query function.

This message may appear baffling, especially if you have several occurrences of sqlsrv_query on a page, and you may have added a new occurrence after you closed your connection.

Since I wasted an enormous amount of time tracing the normal channels, I thought referencing this error here would provide some help. In was hung up on "parameter" and was thinking it was a bad parameter object, and overlooked passing an undefined connection object to sqlsrv_query

Tip: It may seem obvious, but you need to trim your strings down to fit in the database field you are saving them to via a parametrized query or a stored procedure. (IE: only submit up to 20 characters to a VARCHAR(20) database field). If you send a larger string to the query then it can handle, you will get an error.

When cleaning up your strings, you will most likely find yourself using the php substr() function. This function will return, as documented, a boolean FALSE value when presented with an empty string. Not minding this boolean FALSE value will cause "0" to be saved in your database tables instead of an empty string.

Since trimming your input is also important, the simple and intuitive solution for this is to trim your substr() output, which will consistently supply and empty string, not boolean FALSE.

So this will always work:
//trim last returns our empty string as a data type of string
$address_line_2 = trim(substr($_POST['addr2']),0,30));

gettype($address_line_2);  //outputs string

//executing a database query will save "" in field tblAddressBook.addr2
$sql = "update tblAddressBook set name=(?), addr1=(?), addr2=(?),..."
$params = array($name, $address_line_1, $address_line_2, ...)
$sql_srv_query($db_conn, $sql, $params);

This second way will give seemingly unexpected data in your database.
//if the result of trimming our post variable is "" (empty), substr() will return FALSE
$address_line_2 = substr(trim($_POST['addr2'])),0,30);

//$address_line_2 actually === FALSE, not ""
echo gettype($address_line_2);  //outputs boolean

//executing a database query will save "0" in field tblAddressBook.addr2
$sql = "update tblAddressBook set name=(?), addr1=(?), addr2=(?),..."
$params = array($name, $address_line_1, $address_line_2, ...)
$sql_srv_query($db_conn, $sql, $params);


You can also cast the type as a string using,
which will cast the boolean false back to the expected Empty String.

= (string)substr(trim($_POST['addr2'])),0,30);

gettype($address_line_2);  //outputs string

//executing a database query will save "" in field tblAddressBook.addr2
$sql = "update tblAddressBook set name=(?), addr1=(?), addr2=(?),..."
$params = array($name, $address_line_1, $address_line_2, ...)
$sql_srv_query($db_conn, $sql, $params);


I didn't notice this behavior until switching to IIS7, PHP 5.3.8 and SQL Server 2008.  But the behavior also is exhibited with IIS7, PHP 5.2 and SQL Server 2008.

If you hit an error "[Microsoft][ODBC Driver Manager] Invalid cursor state " when you specify valid Scrollable cursor, please check following bug report:


There is currently a bug that requires options Scrollable to be specified before QueryTimeout in corresponding array.
