如何选择除SQL 17中某些列以外的所有列

Question

我有很多查询要加入一个查询，这些查询与该列重复的一个id列一起加入。

select t1.* , t2.* , t3.* , ...
from (query1) as t1 , (query2) as t2 , (query3) as t3 , ...
where t1.id1 = t2.id2 and t1.id1 = t3.id3 and ...

查询有很多列，我想选择每个查询中除某些列之外的所有列。例如：

select t1.(all columns except some columns) , t2.(all columns except some columns) , t3.* , ...
from (query1) as t1 , (query2) as t2 , (query3) as t3 , ...
where t1.id1 = t2.id2 and t1.id1 = t3.id3 and ...

如何选择除SQL 17中的某些列以外的所有列？感谢您的建议。

这只是解决方法-

-- In step 1 insert your query output to a temp table
SELECT *
INTO #Temp
FROM
(
   select t1.* , t2.* , t3.* , ...
   from (query1) as t1 , (query2) as t2 , (query3) as t3 , ...
   where t1.id1 = t2.id2 and t1.id1 = t3.id3 and ...
)

-- Then drop all columns from the temp table you wants to exclude 
-- from your final selection
ALTER TABLE #Temp
DROP COLUMN column_name1, column_name2

-- Finally, just select all records from temp table
SELECT * FROM #Temp
