如何使用 SQL 函数 CONCAT 和 LIKE

Question

我确认 SQL table 中的列包含我正在搜索的结果（结果为 NA），但是当我使用下面的查询时，没有返回任何结果。请问我能得到一些帮助吗？

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

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

Answer 2

我有点不明白你为什么要在这里使用 CONCAT()。这不是你想要的吗？

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

当然更容易理解
