第一眼看： CASE WHEN 语句不完整。必须以 END 字结束！在这两种情况下！



看看这里： CASE（SQL） [ ^ ]

On the first look: CASE WHEN statement is incomplete. Must be ended with END word! In both cases!

Have a look here: CASE (SQL)[^]

对于初学者，我怀疑第一个错误是由以下原因引起的：

For starters, I suspect the first error is caused by:

SELECT CASE when mytable='CertUserToAccount' then CertUserToAccount

，如第13行的错误所示。



'SELECT'语句别名为't'，但它从哪里选择？

as indicated by Error on line 13.

The 'SELECT' statement is aliased to 't', but where is it selecting anything from?
