使用来自两个select语句的绑定参数,并在一个插入中使用它们

我试图弄清楚如何从两个不同的select语句中获取绑定参数值并将其插入到新表中。

我的第一选择得到一个没有问题的阵列。我的第二个选择得到一个计数,以及除以该计数的数字180,但是使用where子句中第一个选择返回的值。

这一切都完美。

现在,基于第二个选择的执行,我想将每个选择的值插入一个新表中。

我要分别绑定每个选择的值,但是如何绑定两个选择的值以对它们执行插入?

$selectPLC = "
    SELECT 
        sku_id, s.frm as frm, sg.code as code, s.matrl as matrl, s.color as color, cst
    FROM plc;
";

try {
    $PLCcheck = $MysqlConn->prepare($selectPLC);
    $detailRslt = $PLCcheck->execute();

     while ($PLCRow = $PLCcheck->fetch(PDO::FETCH_ASSOC)) {

        print_r($PLCRow); //This prints the first array I need

        $salesValues = [
        ":cst" => $PLCRow["cst"],
        ":frm" => $PLCRow["frm"],
        ":matrl" => $PLCRow["matrl"],
        ":color" => $PLCRow["color"]

        ];

        $checkSales = "
            SELECT
            count(*) as salesCount,
            180/count(*) as countDIV
            FROM orders
                WHERE cstnoc = :cst
                AND frmc = :frm
                AND covr1c = :matrl
                AND colr1c = :color
                AND date(substr(dateField1,1,4)||'-'||substr(dateField1,5,2)||'-'||substr(dateField1,7,2) ) between current_Date - 180 DAY AND current_Date
        ";

        try{
            $salesCheck = $DB2Conn->prepare($checkSales);
            $salesResult = $salesCheck->execute($salesValues);

            while ($salesRow = $salesCheck->fetch(PDO::FETCH_ASSOC)) {

                print_r($salesRow); //This prints the 2nd array I need

                $countValues = [
                    ":salesCount" => $salesRow["salesCount"],
                    ":countDiv" => $salesRow["countDiv"]
                ];

                $insertSales = "

                    INSERT INTO metrics (cst, frm, matrl, color, salesCount, countDIV )
                    VALUES (
                        :cst, //from first array
                        :frm, //from first array
                        :matrl, //from first array
                        :color, //from first array
                        :salesCount, //from 2nd array
                        :countDiv //from 2nd array
                    )
                ";

                $salesInsertPrep = $DB2Conn->prepare($insertSales);
                $salesInsertExec = $salesInsertPrep->execute($countValues);
            }

        }catch(PDOException $ex) {
            echo "QUERY TWO FAILED!: " .$ex->getMessage(); 
        }
    }

}catch(PDOException $ex) {
    echo "QUERY ONE FAILED!: " .$ex->getMessage();
}

获取第二个数组值而不是将它们添加到新数组中时,可以将它们添加到第一个值数组中,因此...... p

       $countValues = [
            ":salesCount" => $salesRow["salesCount"],
            ":countDiv" => $salesRow["countDiv"]
        ];

使用

$salesValues[":salesCount"] = $salesRow["salesCount"];
$salesValues[":countDiv"] = $salesRow["countDiv"];

然后...

$salesInsertExec = $salesInsertPrep->execute($salesValues);

另一件事是,您可以在循环外准备一次插入,然后在循环中每次执行插入,因此看起来就像...

    $insertSales = "
                INSERT INTO metrics (cst, frm, matrl, color, salesCount, countDIV )
                VALUES (
                    :cst, //from first array
                    :frm, //from first array
                    :matrl, //from first array
                    :color, //from first array
                    :salesCount, //from 2nd array
                    :countDiv //from 2nd array
                )
            ";

    $salesInsertPrep = $DB2Conn->prepare($insertSales);
    while ($salesRow = $salesCheck->fetch(PDO::FETCH_ASSOC)) {

        print_r($salesRow); //This prints the 2nd array I need

        $salesValues[":salesCount"] = $salesRow["salesCount"];
        $salesValues[":countDiv"] = $salesRow["countDiv"];
        $salesInsertExec = $salesInsertPrep->execute($salesValues);
   }
