T-SQL在select语句中使用varchar

I need to use the return of a function (VARCHAR) as columns in a select statement. For example:

我需要在select语句中使用函数返回(VARCHAR)作为列。例如:

A function fn1 returns a varchar @result='Alice,Bob'. How can I do a query using @result in a select statement, e.g:

函数fn1返回varchar @ result ='Alice,Bob'。如何在select语句中使用@result进行查询,例如:

SELECT @result FROM B 

and obtain the records of the columns Alice and Bob of another Table.

并获取另一个表的Alice和Bob列的记录。

Thanks in advance

Try exec('select ' + fn_1() + ' from T')

尝试exec(从T'''选择'+ fn_1()+')
