Question

我确认SQL表中的列包含我要搜索的结果（结果为NA），但是当我使用下面的查询时，没有返回结果。我可以帮忙吗？

SELECT DISTINCT * 
FROM [DB_NAME].[dbo].[TABLE_NAME]
WHERE BECDescription like '%Time Warner%' AND
      (CONCAT(PhysicalAddress1, PhysicalCity, PhysicalStateProvince) like ('%NA%  %NA% %NA%')
      ) AND
      PhysicalCountry like '%NA%' AND
      CarrierName like '%NA%' AND
      CurrNetChargeAmt = 1326.00

Answer 1

我对您为什么在这里使用CONCAT()感到有些困惑。这不是您想要的吗？

WHERE BECDescription like '%Time Warner%' AND
      PhysicalAddress1 like '%NA%' AND
      PhysicalCity like '%NA%' AND
      PhysicalStateProvince like '%NA%' AND
      PhysicalCountry like '%NA%' AND
      CarrierName like '%NA%' AND
      CurrNetChargeAmt = 1326.00

这当然更容易理解。

Answer 2

您连接了PhysicalAddress1，PhysicalCity，PhysicalStateProvince，但在'％NA'之间添加了空格。

尝试

SELECT DISTINCT * 
FROM [db_name].[dbo].[table_name]
WHERE BECDescription like '%Time Warner%' AND (CONCAT(PhysicalAddress1, ' ', PhysicalCity, ' ', PhysicalStateProvince) like ('%NA% %NA% %NA%')) AND PhysicalCountry like '%NA%' AND CarrierName like '%NA%' AND CurrNetChargeAmt = 1326.00

如何在LIKE中使用SQL函数CONCAT
