用 ms sql 标量值函数,应该在函数前面加上 "dbo.",否则会报 “不是可以识别的 内置函数名称”错误。例如
declare @whichdb tinyint;
select @whichdb = user_getwhichdb(1);--看看是哪个的
=================================================
--标量值函数
alter function [dbo].[user_getwhichdb]
(
@userid int = 0
)
returns tinyint
with execute as caller
as
begin
declare @whichdb tinyint;
set @whichdb = 1;
if @userid >= 115098
set @whichdb = 2;
return (@whichdb);
end
