需要有关SQL语句的帮助

Question

您好我在以下SQL语句中收到“解析错误：语法错误，意外的T_STRING”。任何帮助谢谢

$result2 = ($con,SELECT 
                       Customers.CustomerId, JrnlHdr.Reference, JrnlRow.DistNumber, LineItem.ItemId, LineItem.ItemDescription 
                 FROM "JrnlHdr", "JrnlRow", "Customers", "LineItem" 
                 WHERE JrnlHdr.POSOisClosed = 0 
                   AND JrnlHdr.PostOrder = JrnlRow.PostOrder 
                   AND JrnlHdr.CustVendId = Customers.CustomerRecordNumber 
                   AND JrnlRow.temRecordNumber = LineItem.ItemRecordNumber 
                   AND JrnlHdr.JrnlKey_Journal = 11);

Answer 1

查询应该是一个字符串，使用引号：

$result2 = ($con,'SELECT Customers.CustomerId, JrnlHdr.Reference, JrnlRow.DistNumber, LineItem.ItemId, LineItem.ItemDescription FROM "JrnlHdr", "JrnlRow", "Customers", "LineItem" WHERE JrnlHdr.POSOisClosed = 0 AND JrnlHdr.PostOrder = JrnlRow.PostOrder AND JrnlHdr.CustVendId = Customers.CustomerRecordNumber AND JrnlRow.temRecordNumber = LineItem.ItemRecordNumber AND JrnlHdr.JrnlKey_Journal = 11');

但是，此代码仍会导致其他错误。您需要调用函数来查询数据库，例如mysqli_query：

$result2 = mysqli_query($con,'SELECT Customers.CustomerId, JrnlHdr.Reference, JrnlRow.DistNumber, LineItem.ItemId, LineItem.ItemDescription FROM "JrnlHdr", "JrnlRow", "Customers", "LineItem" WHERE JrnlHdr.POSOisClosed = 0 AND JrnlHdr.PostOrder = JrnlRow.PostOrder AND JrnlHdr.CustVendId = Customers.CustomerRecordNumber AND JrnlRow.temRecordNumber = LineItem.ItemRecordNumber AND JrnlHdr.JrnlKey_Journal = 11');
