PHP：参数计数和参数计数不匹配

Question

我的 php 应用程序正在使用 MS SQLSrv 驱动程序。调用数据库中的存储过程时，运行 sqlsrv_execute() 后出现以下错误：参数计数和参数计数不匹配。我的代码如下：

    $sql = "{call myStoredProcedure(?, ?, ?, ?, ?, ?)}";

    //Passing by reference instead of value, otherwise sqlsrv_prepare is not happy
    $params = array(array(&$param1, SQLSRV_PARAM_IN),
                    array(&$param2, SQLSRV_PARAM_IN),
                    array(&$param3, SQLSRV_PARAM_IN),
                    array(&$param4, SQLSRV_PARAM_IN),
                    array(&$param5, SQLSRV_PARAM_IN),
                    array(&$param6, SQLSRV_PARAM_OUT)
                    );

    /* Create the statement. */
    $stmt = sqlsrv_prepare( $conn, $sql, $params);
    if( $stmt )
    {
         echo "Statement prepared.\n";
    }
    else
    {
         echo "Error in preparing statement.\n";
         die( print_r( sqlsrv_errors(), true));
    }

    //TODO: Resolve error, "param count and argument count don't match"
    $stmt = sqlsrv_execute($conn, $sql, $params);

    //This statement will run, but no rows are returned and rowCount is false.
    //$stmt = sqlsrv_query($conn, $sql, $params);

    $rowCount = sqlsrv_num_rows( $stmt );
    $numFields = sqlsrv_num_fields( $stmt );

    //Rest of code...

我为此花了一个小时并梳理了 PHP.Net 和 Microsoft 文档。有没有其他人遇到过类似的错误？任何帮助表示赞赏。

是的，我检查了我的参数计数，我的存储过程需要 6 个参数。

更新：

存储过程sn-p：

ALTER PROCEDURE [dbo].[myStoredProcedure] 
    @param1 VARCHAR(64),
    @param2 VARCHAR(64),
    @param3 DATETIME, 
    @param4 DATETIME,
    @param5 INT = 9,
    @param6 INT OUTPUT
AS
BEGIN

//Do stuff 

END

您错误地使用了SQLSRV_EXECUTE。您得到的错误实际上是一个 PHP 错误，告诉您将错误的参数传递给 SQLSRV_EXECUTE。

定义为： sqlsrv_execute(resource $stmt)
但是你打电话给：sqlsrv_execute($conn, $sql, $params)

假设存储过程设置正确，我已经修复了下面的代码。让我知道它是否有效。

$sql = "{call myStoredProcedure(?, ?, ?, ?, ?, ?)}";

//Passing by reference instead of value, otherwise sqlsrv_prepare is not happy
$params = array(array(&$param1, SQLSRV_PARAM_IN),
                array(&$param2, SQLSRV_PARAM_IN),
                array(&$param3, SQLSRV_PARAM_IN),
                array(&$param4, SQLSRV_PARAM_IN),
                array(&$param5, SQLSRV_PARAM_IN),
                array(&$param6, SQLSRV_PARAM_OUT)
                );

/* Create the statement. */
$stmt = sqlsrv_prepare( $conn, $sql, $params);
if( $stmt )
{
     echo "Statement prepared.\n";
}
else
{
     echo "Error in preparing statement.\n";
     die( print_r( sqlsrv_errors(), true) );
}

//Shouldn't assign this to $stmt, $stmt can be reused for multiple sqlsrv_execute() calls
$result = sqlsrv_execute($stmt);

if($result === false)
{
    //Error handling
}
else
{
    $rowCount = sqlsrv_num_rows( $result );
    $numFields = sqlsrv_num_fields( $result );
}
