Question

我正在尝试调用预准备语句并检索所需数据。准备好的声明由另一位开发人员创建，他们的指示是：</ p>

declare @DeliveryC nvarchar(15), @DeliveryS  float,  @ErrMsg varchar 

EXECUTE my_prepared_statement @CustNum = 'XX', @PostCode = '2222', @Suburb = 'XX' 
,       @DeliveryCode = @DeliveryC output, @DeliverySurcharge = @DeliveryS output, @ErrMsg = @ErrMsg output

我一直收到这个错误：

数组（[0] =＆gt;数组（[0] =＆gt; 42000 [SQLSTATE] =＆gt; 42000 [1] =＆gt; 201 [code] =＆gt; 201 [2] =＆gt; [Microsoft] [SQL Server的ODBC驱动程序13] [SQL 服务器]过程或函数'my_prepared_statement'需要参数 “@DeliverySurcharge”，未提供。

我的PHP代码如下所示：

    $serverName = "XX"; 
    $connectionInfo = array( "Database"=>"XX", "UID"=>"XX", "PWD"=>"XX");
    $conn = sqlsrv_connect( $serverName, $connectionInfo);


    if($conn) {
        echo "Connection established";

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

        $custNum = "XX";  
        $postcode = "2222";  
        $suburbname = "XX";  
        $dcode = "dcode";  
        $dsur = 0.0;  
        $emsg = "error";  
        $params = array(   
            array($custNum, SQLSRV_PARAM_IN),  
            array($postcode, SQLSRV_PARAM_IN),  
            array($suburbname, SQLSRV_PARAM_IN),  
            array(&$dcode, SQLSRV_PARAM_OUT), 
            array(&$dsur, SQLSRV_PARAM_OUT), 
            array(&$emsg, SQLSRV_PARAM_OUT) 
        ); 

        $stmt3 = sqlsrv_query( $conn, $sql, $params);

        if( $stmt3 === false )  
        {  
            echo "<br/>Error in executing statement 3.<br/>";  
            die( print_r( sqlsrv_errors(), true)); 
        }

        echo "surcharge: " . $dsur . "  ---  code: " . $dcode; 
    }
    else {
        echo "Connection could not be established";
    }

The developer who created the prepared statement has sent me through this information:

    declare @DeliveryC nvarchar(15), @DeliveryS  float,  @ErrMsg varchar 

    EXECUTE my_prepared_statement @CustNum = 'XX', @PostCode = '2222', @Suburb = 'XX' 
    ,       @DeliveryCode = @DeliveryC output, @DeliverySurcharge = @DeliveryS output, @ErrMsg = @ErrMsg output

我以前从未真正使用过这样的预处理语句，所以我有点迷失了。对不起，如果我没有解释这个。任何想法如何修复错误并获取数据？
