如何从数据库中获取以逗号分隔的值的数据[重复]

Question

我试过这段代码，但它只获取逗号中最后一个值的值

我在INVOICEVALUE = 1,2

它只获取 2

$INVOICEVALUE = $_REQUEST["INVOICEVALUE"];
$VALUE = explode(',', $INVOICEVALUE);
foreach ($VALUE as $val) {

    $invoiceselected = mysqli_query($link, "select SUM(INVOICE_AMOUNT) as AMOUNT,INVOICE_CODE,INVOICE_STATUS,PAYMENT_STATUS,INVOICE_TRANSACTIONDATE,INVOICE_UNITPRICE,CUSTOMER_ID,CUSTOMER_ID
         from invoice where INVOICE_CODE ='" . $val . "' 
         AND INVOICE_STATUS='CLOSE' AND PAYMENT_STATUS=''
         GROUP BY INVOICE_CODE");
}

Answer 1

如果您想同时获得INVOICE_CODE = 1 或INVOICE_CODE = 2 的结果，那么您可以使用MySQL IN clause

$INVOICEVALUE = $_REQUEST["INVOICEVALUE"];
//$VALUE = explode(',', $INVOICEVALUE);


$invoiceselected = mysqli_query($link, "select SUM(INVOICE_AMOUNT) as AMOUNT,INVOICE_CODE,INVOICE_STATUS,PAYMENT_STATUS,INVOICE_TRANSACTIONDATE,INVOICE_UNITPRICE,CUSTOMER_ID,CUSTOMER_ID
     from invoice where INVOICE_CODE IN (" . $INVOICEVALUE . ") 
     AND INVOICE_STATUS='CLOSE' AND PAYMENT_STATUS=''
     GROUP BY INVOICE_CODE");

希望这会有所帮助！
