在一箇中添加3列

Question

我正在研究此查詢表單，我沒有找到任何答案。我不知道該怎麼做。

所以，我有這個疑問這個結果：

代碼：

select distinct Phase as tt from table1 
     where phase is not null 

select distinct [ITV en cours] as tt from table1 
     where [ITV en cours] = 'OUI' 

select distinct Etat as tt from table1 
     where Etat like 'Ass%' 

我想讓這樣的事情

哪有我這樣做？

Answer 1

你可以插入或UNION ALL或工會，從而獲得所需結果

select distinct Phase as tt from table1 where phase is not null 
    union all 
    select distinct [ITV en cours] as tt from table1 where [ITV en cours] = 'OUI' 
    union all 
    select distinct Etat as tt from table1 where Etat like 'Ass%'
