類似TSQL的問題

Question

什麼是更好的方式來編寫下面的Transact SQL？

select * from table1 where columnA like '%ABC%' and columnB = 1 

select * from table1 where columnA like '%DEF%' and columnB = 1 

select * from table1 where columnA like '%GHI%' and columnB = 1 

，纔有可能鞏固上述3個SQL語句轉換爲一個SELECT語句

Answer 1

select * 

from table1 

where columnB = 1 and 
     (columnA like '%ABC%' or 
      columnA like '%DEF%' or 
      columnA like '%GHI%') 

Answer 2

select * from table1 
where (columnA like '%ABC%' 
     or columnA like '%DEF%' 
     or columnA like '%GHI%') 
    and columnB = 1 

Answer 3

你可以試試這個

select * from table1 
where (columnA like '%ABC%' 
    or columnA like '%DEF%' 
    or columnA like '%GHI%') 
and columnB = 1
