Question

我经常使用此查询来检索与数据库中的字符串匹配的所有列。我试图链接两个表，并且这样做我需要匹配列来连接两个。

我希望能够搜索的是一个包含字符串＆＃34; CUSTOMER_ID＆＃34;的列的表。和另一列＆＃34; WORKORDER_BASE_ID＆＃34;

有没有一种简单的方法可以做到这一点，从这个sqript工作？我认为某些类型的子查询可能是必要的，但我还没有做任何工作。

SELECT 
    t.name AS table_name
    ,SCHEMA_NAME(schema_id) AS schema_name
    ,c.name AS column_name
    ,T.modify_date
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE 
    c.name LIKE '%CUSTOMER_ID%'                                       
ORDER BY modify_date

这样的事情应该有效：

SELECT  t.name AS table_name ,
        SCHEMA_NAME(schema_id) AS schema_name ,
        c.name AS column_name ,
        T.modify_date
FROM    sys.tables AS t
        INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE   EXISTS ( SELECT *
                 FROM   sys.columns c1
                 WHERE  c1.object_id = c.object_id
                        AND c1.name = 'CUSTOMER_ID' )
        AND EXISTS ( SELECT *
                     FROM   sys.columns c1
                     WHERE  c1.object_id = c.object_id
                            AND c1.name = 'WORKORDER_BASE_ID' )
ORDER BY modify_date

在SQL数据库的表中查找两列
