Answer 1

你可以通過在存儲過程中使用動態SQL來實現這一點。

CREATE PROCEDURE SelectEmpWithComdition @mgr int 
AS 
BEGIN 
declare @query varchar(max), @condition varchar(max) 
set @query = 'select empid, empname, rank from employees where ' 
select @condition = Condtition from Conditions where mgr = @mgr 

set @query = @query + @condition 
exec sp_executesql @query 

END 

Answer 2

它會給你一些想法。

Declare @Command varchar(Max) 
Declare @condition varchar(100) 

Select @condition = condition from [rank] where mgr = 2 

Set @Command = 'Select * from Empployee 
where ' + @condition 

Execute (@Command)
