Question

我想在单个存储过程下运行10个选择查询，并使用输出参数分别获取每个选择查询的结果，并使用 php和sqlsrv库显示输出到前端。怎么弄它？

Answer 1

我不知道如何在PHP中执行此操作，但您通常可以使用不需要任何特殊客户端API的结果集替换输出参数。

EG

declare @count1  int = (select count(*) from sys.objects)
declare @count2  int = (select count(*) from sys.columns)

select * 
from (values ('count1', @count1),('count2', @count2) ) as t(pn,pv)

Answer 2

它是基本的，但却是一个有效的例子。

数据库部分：

USE [TestDatabase]
CREATE PROCEDURE [TestProcedure]
    @P1 int OUTPUT,
    @P2 int OUTPUT,
    @P3 int OUTPUT,
    @P4 int OUTPUT,
    @P5 int OUTPUT,
    @P6 int OUTPUT,
    @P7 int OUTPUT,
    @P8 int OUTPUT,
    @P9 int OUTPUT,
    @P10 int OUTPUT
AS
BEGIN
    SET NOCOUNT ON;

    -- It's very basic example.
    -- Put here your own SQL statements, which must return single values
    SELECT @P1 = 1
    SELECT @P2 = 2
    SELECT @P3 = 3
    SELECT @P4 = 4
    SELECT @P5 = 5
    SELECT @P6 = 6
    SELECT @P7 = 7
    SELECT @P8 = 8
    SELECT @P9 = 9
    SELECT @P10 = 10
END

PHP部分：

<?php
// Connection
$server = 'server\instance,port';
$cinfo = array(
    "Database"=>'TestDatabase',
    "UID"=>"User",
    "PWD"=>"Password"
);
$conn = sqlsrv_connect($server, $cinfo);
if( $conn === false )
{
    echo "Error (sqlsrv_connect): ".print_r(sqlsrv_errors(), true);
    exit;
}

// Call stored procedure
$sql = '{call TestProcedure(?, ?, ?, ?, ?, ?, ?, ?, ?, ?)}';
$p1 = 0;
$p2 = 0;
$p3 = 0;
$p4 = 0;
$p5 = 0;
$p6 = 0;
$p7 = 0;
$p8 = 0;
$p9 = 0;
$p10 = 0;
$params = array(
    array(&$p1, SQLSRV_PARAM_INOUT),
    array(&$p2, SQLSRV_PARAM_INOUT),
    array(&$p3, SQLSRV_PARAM_INOUT),
    array(&$p4, SQLSRV_PARAM_INOUT),
    array(&$p5, SQLSRV_PARAM_INOUT),
    array(&$p6, SQLSRV_PARAM_INOUT),
    array(&$p7, SQLSRV_PARAM_INOUT),
    array(&$p8, SQLSRV_PARAM_INOUT),
    array(&$p9, SQLSRV_PARAM_INOUT),
    array(&$p10, SQLSRV_PARAM_INOUT)
);
$stmt = sqlsrv_query($conn, $sql, $params);
if( $stmt === false ) {
    echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
    exit;
}

// Output parameters are available after consuming all resultsets.
while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
}
sqlsrv_free_stmt($stmt);
sqlsrv_close($conn);

// Output
echo 'Parameters values'."</br>";
echo 'Parameter 1: '.$p1."</br>";
echo 'Parameter 2: '.$p2."</br>";
echo 'Parameter 3: '.$p3."</br>";
echo 'Parameter 4: '.$p4."</br>";
echo 'Parameter 5: '.$p5."</br>";
echo 'Parameter 6: '.$p6."</br>";
echo 'Parameter 7: '.$p7."</br>";
echo 'Parameter 8: '.$p8."</br>";
echo 'Parameter 9: '.$p9."</br>";
echo 'Parameter 10: '.$p10."</br>";
?>

使用php中的输入和输出参数调用SQL Server存储过程
