[英]PHP SQL Update Query failing
我试图在PHP中运行此SQL查询:
UPDATE
billing_calldata
SET
status = 'c',
customer = '475',
description = 'UK Mobile VMNO C&W (fw7-C&W)',
customer_cost = '0.00720416666666667',
customer_ac = '0',
customer_sc = '0',
reseller_cost = '0',
reseller_ac = '0',
reseller_sc = '0'
WHERE序列= 10364723
但它返回此错误:
UPDATE
billing_calldata
SET
status = 'c',
customer = '475',
description = 'UK Mobile VMNO CYou have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''UK Mobile VMNO C' at line 1
description
是UK Mobile VMNO C&W (fw7-C&W)
但是查询在phpMyAdmin
直接工作正常
该查询源自我的vb.net应用程序:
SQL = "UPDATE billing_calldata SET " _
& "status = 'c', " _
& "customer = '" & customer_sequence & "', " _
& "description = '" & description & "', " _
& "customer_cost = '" & customer_cost & "', " _
& "customer_ac = '" & customer_ac & "', " _
& "customer_sc = '" & customer_sc & "', " _
& "reseller_cost = '" & reseller_cost & "', " _
& "reseller_ac = '" & reseller_ac & "', " _
& "reseller_sc = '" & reseller_sc & "' " _
& "WHERE sequence = " & sequence & " "
SQL = "apikey=1nt3gr4&submittedSQL=" + SQL
然后我将这个发送请求发送到PHP页面,其中包含以下内容:
if($_POST["apikey"] <> '' and $_POST["apikey"] == '1nt3gr4' and $_POST["submittedSQL"] <> '') {
$sql = $_POST["submittedSQL"];
mysql_query($sql, $conn) or die(mysql_error());
}
使用real_escape_string转义特殊字符:
$description = $mysqli->real_escape_string($description);
然后在UPDATE
使用$description
。
