sqlsrv_query

Download PHP driver

Prepares and executes a statement.

Syntax

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

Parameters

$conn: The connection resource associated with the prepared statement.

$tsql: The Transact-SQL expression that corresponds to the prepared statement.

$params [OPTIONAL]: An array of values that correspond to parameters in a parameterized query. Each element of the array can be one of the following:

  • A literal value.

  • A PHP variable.

  • An array with the following structure:

    array($value [, $direction [, $phpType [, $sqlType]]])  
    

    The description for each element of the array is in the following table:

    Element Description
    $value A literal value, a PHP variable, or a PHP by-reference variable.
    $direction[OPTIONAL] One of the following SQLSRV_PARAM_* constants used to indicate the parameter direction: SQLSRV_PARAM_IN, SQLSRV_PARAM_OUT, SQLSRV_PARAM_INOUT. The default value is SQLSRV_PARAM_IN.

    For more information about PHP constants, see Constants (Microsoft Drivers for PHP for SQL Server).
    $phpType[OPTIONAL] A SQLSRV_PHPTYPE_* constant that specifies PHP data type of the returned value.

    For more information about PHP constants, see Constants (Microsoft Drivers for PHP for SQL Server).
    $sqlType[OPTIONAL] A SQLSRV_SQLTYPE_* constant that specifies the SQL Server data type of the input value.

    For more information about PHP constants, see Constants (Microsoft Drivers for PHP for SQL Server).

$options [OPTIONAL]: An associative array that sets query properties. It is the same list of keys also supported by sqlsrv_prepare.

Return Value

A statement resource. If the statement cannot be created and/or executed, false is returned.

Remarks

The sqlsrv_query function is well-suited for one-time queries and should be the default choice to execute queries unless special circumstances apply. This function provides a streamlined method to execute a query with a minimum amount of code. The sqlsrv_query function does both statement preparation and statement execution, and can be used to execute parameterized queries.

Example 1

In the following example, a single row is inserted into the Sales.SalesOrderDetail table of the AdventureWorks database. The example assumes that SQL Server and the AdventureWorks database are installed on the local computer. All output is written to the console when the example is run from the command line.

Note

Although the following example uses an INSERT statement to demonstrate the use of sqlsrv_query for a one-time statement execution, the concept applies to any Transact-SQL statement.

<?php  
/* Connect to the local server using Windows Authentication and  
specify the AdventureWorks database as the database in use. */  
$serverName = "(local)";  
$connectionInfo = array("Database"=>"AdventureWorks");  
$conn = sqlsrv_connect($serverName, $connectionInfo);  
if ($conn === false) {  
    echo "Could not connect.\n";  
    die(print_r(sqlsrv_errors(), true));  
}  
  
/* Set up the parameterized query. */  
$tsql = "INSERT INTO Sales.SalesOrderDetail   
        (SalesOrderID,   
         OrderQty,   
         ProductID,   
         SpecialOfferID,   
         UnitPrice,   
         UnitPriceDiscount)  
        VALUES   
        (?, ?, ?, ?, ?, ?)";  
  
/* Set parameter values. */  
$params = array(75123, 5, 741, 1, 818.70, 0.00);  
  
/* Prepare and execute the query. */  
$stmt = sqlsrv_query($conn, $tsql, $params);  
if ($stmt) {  
    echo "Row successfully inserted.\n";  
} else {  
    echo "Row insertion failed.\n";  
    die(print_r(sqlsrv_errors(), true));  
}  
  
/* Free statement and connection resources. */  
sqlsrv_free_stmt($stmt);  
sqlsrv_close($conn);  
?>  

Example 2

The following example updates a field in the Sales.SalesOrderDetail table of the AdventureWorks database. The example assumes that SQL Server and the AdventureWorks database are installed on the local computer. All output is written to the console when the example is run from the command line.

<?php  
/* Connect to the local server using Windows Authentication and  
specify the AdventureWorks database as the database in use. */  
$serverName = "(local)";  
$connectionInfo = array("Database"=>"AdventureWorks");  
$conn = sqlsrv_connect($serverName, $connectionInfo);  
if ($conn === false) {  
    echo "Could not connect.\n";  
    die(print_r(sqlsrv_errors(), true));  
}  
  
/* Set up the parameterized query. */  
$tsql = "UPDATE Sales.SalesOrderDetail   
         SET OrderQty = (?)   
         WHERE SalesOrderDetailID = (?)";  
  
/* Assign literal parameter values. */  
$params = array(5, 10);  
  
/* Execute the query. */  
if (sqlsrv_query($conn, $tsql, $params)) {  
    echo "Statement executed.\n";  
} else {  
    echo "Error in statement execution.\n";  
    die(print_r(sqlsrv_errors(), true));  
}  
  
/* Free connection resources. */  
sqlsrv_close($conn);  
?>  

Note

It is recommended to use strings as inputs when binding values to a decimal or numeric column to ensure precision and accuracy as PHP has limited precision for floating point numbers. The same applies to bigint columns, especially when the values are outside the range of an integer.

Example 3

This code sample shows how to bind a decimal value as an input parameter.

<?php
$serverName = "(local)";
$connectionInfo = array("Database"=>"YourTestDB");  
$conn = sqlsrv_connect($serverName, $connectionInfo);  
if ($conn === false) {  
     echo "Could not connect.\n";  
     die(print_r(sqlsrv_errors(), true));  
}  

// Assume TestTable exists with a decimal field 
$input = "9223372036854.80000";
$params = array($input);
$stmt = sqlsrv_query($conn, "INSERT INTO TestTable (DecimalCol) VALUES (?)", $params);

sqlsrv_free_stmt($stmt);  
sqlsrv_close($conn);  

?>

Example 4

This code sample shows how to create a table of sql_variant types and fetch the inserted data.

<?php
$server = 'serverName';
$dbName = 'databaseName';
$uid = 'yourUserName';
$pwd = 'yourPassword';

$options = array("Database"=>$dbName, "UID"=>$uid, "PWD"=>$pwd);
$conn = sqlsrv_connect($server, $options);
if($conn === false) {
    die(print_r(sqlsrv_errors(), true));
}

$tableName = 'testTable';
$query = "CREATE TABLE $tableName ([c1_int] sql_variant, [c2_varchar] sql_variant)";

$stmt = sqlsrv_query($conn, $query);
if($stmt === false) {
    die(print_r(sqlsrv_errors(), true));
}
sqlsrv_free_stmt($stmt);

$query = "INSERT INTO [$tableName] (c1_int, c2_varchar) VALUES (1, 'test_data')";
$stmt = sqlsrv_query($conn, $query);
if($stmt === false) {
    die(print_r(sqlsrv_errors(), true));
}
sqlsrv_free_stmt($stmt);

$query = "SELECT * FROM $tableName";
$stmt = sqlsrv_query($conn, $query);

if(sqlsrv_fetch($stmt) === false) {
    die(print_r(sqlsrv_errors(), true));
}

$col1 = sqlsrv_get_field($stmt, 0);
echo "First field:  $col1 \n";

$col2 = sqlsrv_get_field($stmt, 1);
echo "Second field:  $col2 \n";

sqlsrv_free_stmt($stmt);
sqlsrv_close($conn);

?>

The expected output would be:

First field:  1
Second field:  test_data
