今天执行下列语句的时候报错，在网上找了半天也没找到原因。最后还是自己找到原因了。

Declare @START_STATUS varchar(200)
Declare @FINISH_STATUS varchar(200)

select top 1 @START_STATUS=sws.name,@FINISH_STATUS=fws.name fcc.time_type from
projectcenter.time_field_calculate_config fcc inner join projectcenter.workflow_status sws on
fcc.start_status_id= sws.id inner join projectcenter.workflow_status fws on fcc.finish_status_id= fws.id
where project_group_id=@proj_group_id and auser_id=@user_id

Msg 141, Level 15, State 1, Line 18
A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations.

看这句语句大家就明白了吧。就这样解决了

Declare @FIRST_DATE datetime
Declare @SECOND_DATE datetime
Declare @START_STATUS varchar(200)
Declare @FINISH_STATUS varchar(200)
Declare @TIME_TYPE varchar(200)

select top 1 @START_STATUS=sws.name,@FINISH_STATUS=fws.name,@TIME_TYPE=fcc.time_type from
projectcenter.time_field_calculate_config fcc inner join projectcenter.workflow_status sws on
fcc.start_status_id= sws.id inner join projectcenter.workflow_status fws on fcc.finish_status_id= fws.id
where project_group_id=@proj_group_id and auser_id=@user_id
