说明
sqlsrv_query
( resource $conn
, string $sql
[, array $params
[, array $options
]] ) : mixed
Prepares and executes a query.
参数
conn
A connection resource returned by sqlsrv_connect().
sql
The string that defines the query to be prepared and executed.
params
An array specifying parameter information when executing a parameterized query. Array elements can be any of the following:
- A literal value
- A PHP variable
- An array with this structure: array($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
orfalse
(the default istrue
)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 totrue
. For more information, see sqlsrv_send_stream_data().Scrollable SQLSRV_CURSOR_FORWARD, SQLSRV_CURSOR_STATIC, SQLSRV_CURSOR_DYNAMIC, or SQLSRV_CURSOR_KEYSET
See [http://msdn.microsoft.com/en-us/library/ee376927.aspx » Specifying a Cursor Type and Selecting Rows] in the Microsoft SQLSRV documentation.
返回值

if an error occurred.
范例
Example #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));}?>
注释
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().
