在SQL Server中查询2个不同值的特定列

Question

I don't have much experience with database so this might look silly.

I just can't query the same column for 2 different values.

This is what I am trying:

where  b.idIndice = 10 and b.idIndice = 20

I have both values in this column

Thanks

Answer 1

你的意思是：

SELECT * FROM TBL b WHERE b.idIndice IN (10, 20)

Answer 2

Try :

WHERE b.idIndice = 10 OR b.idIndice = 20

Or

WHERE b.idIndice IN(10, 20)

A value can't be equal to 10 and to 20 at the same time.

Answer 3

use in ()

where b.idIndice in (10,20)
