[已解决]如何在Sql Query中将数字更改为单词?

问题描述:

我希望显示ststus列的值为1,2,3。这里

1表示待定,2表示已批准,3表示被拒绝。

但是如何在gridview中显示数字而不是用correspoding替换这个数字

words?

I want display ststus column with values 1,2,3. Here
1 indicates Pending,2 indicates approved, and 3 indicates rejected.
But instead of displaying numbers in gridview how can I replace this with correspoding
words?

它的简单你可以在你的SQL查询中使用Case。

这里例如现在我使用字段名称作为状态



Its simple you can use Case in your sql query.
here for example now iam using the field name as Status

Select Status, case When status =1 Then 'Pending'
When status =2 then 'approved'
When status =3 then 'rejected'
else 'noStatus' END as 'Status'
from 
TableName


在SQL查询中使用CASE

Use CASE in sql query
CASE column_name
  WHEN 1 THEN Pending
  WHEN 2 THEN Approved
  WHEN 3 THEN Rejected
END


尝试:

Try:
SELECT CASE ststus
            WHEN 1 THEN 'Pending'
            WHEN 2 THEN 'Approved'
            WHEN 3 THEN 'Rejected'
            ELSE 'ERROR'
       END
FROM MyTable
