存储过程从SQL Server中的存储过程本身获取价值

Question

I have two stored procedures. The first stored procedure value's using in second stored procedure. So I want to combine the two stored procedures into a single one.

Create procedure [carcallD]
   @carid varchar(10)
as
Begin
    select 
       t.dtime, t.locid, t.vtid 
    from 
       Transaction_tbl t 
    where 
       Tbarcode = @carid
End

If I execute this with carid of 413 I will get out put like this:

dtime                        locid       vtid
-----------------------     ----------- -----------
2014-06-09 14:59:47           5             8

My other stored procedure looks like this:

ALTER procedure [dbo].[Weekend]
   @wday varchar(50),
   @yr varchar(50),
   @vtid integer,
   @locid integer
as
begin
   set nocount on

   DECLARE @todaysdate date
   Declare @checkWeekend integer

   select  
      @todaysdate = CONVERT(varchar(10), GETDATE(), 111)

   select 
      @checkWeekend = Weekend 
   from 
      weekends_tbl 
   where 
      weekdays = @wday

   if @checkWeekend = 1
   begin
      select Hamount as amount 
      from locvtypeassign_tbl 
      where vtid = @vtid and locid = @locid and active = 0
   end
   else
   begin
      if @todaysdate in (select Hdate from Pholidays_tbl where year = @yr)
      begin
         select Hamount as amount 
         from locvtypeassign_tbl 
         where vtid = @vtid and locid = @locid and active = 0
      end
      else
      begin
         select Namount as amount 
         from locvtypeassign_tbl 
         where vtid = @vtid and locid = @locid and active = 0
      end
   end
end

Here am using parameter

• @wday = I want to pass particular day of dtime from my output
• @yr = pass particular year of dtime from my output
• @vtid = pass vtid from my output
• @locid = pass locid from my output

So can I combine these two stored procedures into a single one?

If anyone is able to help me, I'd appreciate it.

Thanks in advance

I want to get output like this:

dtime                        locid       vtid           amount
 -----------------------     ----------- -----------  ---------
2014-06-09 14:59:47           5             8           100

Answer 1

You can use output parameteres:

CREATE PROCEDURE GetImmediateManager
    @employeeID INT,
    @managerID INT OUTPUT
AS
BEGIN
   SELECT @managerID = ManagerID 
  FROM HumanResources.Employee 
  WHERE EmployeeID = @employeeID
END

Try this

@wday datetime,

@vtid integer, 
@locid integer,

-- taking parameter value 
select @wday = t.dtime 
from Transaction_tbl t where Tbarcode=@carid 
set @day=datename(Weekday,@wday) 
set @year=year(@wday) 
set @vtid = (select t.vtid 
from Transaction_tbl t where Tbarcode=@carid); 
set @locid = (select t.locid 
from Transaction_tbl t where Tbarcode=@carid); 
set nocount on 
DECLARE @todaysdate date 
Declare @checkWeekend integer 
select @todaysdate = CONVERT(varchar(10), GETDATE(), 111) 
--End

Answer 3

You have two stored procedures, the main aim is to use one stored procedure. Since you have two written already. Alter the second procedure add the @carid , add another parameter @option . If your option is 0 then execute the first procedure, else execute the second.

ALTER procedure [dbo].[Weekend]
    @wday varchar(50),
    @yr varchar(50),
    @vtid integer,
    @locid integer,
    @option = 0,
    @carid varchar(10)
as
begin
set nocount on
DECLARE @todaysdate date
Declare @checkWeekend integer
   select  @todaysdate = CONVERT(varchar(10), GETDATE(), 111)

select @checkWeekend=   Weekend from weekends_tbl where weekdays=@wday
if @option = 1
beging
   exec [carcallD] @carid
end
else
begin
if @checkWeekend= 1
begin
   select Hamount as amount from locvtypeassign_tbl where 
   vtid=@vtid and locid=@locid and active=0
end
else
begin
if @todaysdate in(select Hdate from Pholidays_tbl where year=@yr)
begin
  select Hamount  as amount from locvtypeassign_tbl where 
   vtid=@vtid and locid=@locid and active=0
end
else
begin
    select Namount as amount from locvtypeassign_tbl where 
    vtid=@vtid and locid=@locid and active=0
end
end
end
end 

You can copy your first procedure also and past in the place of exec there by eliminating it. like

if @option = 1 
begin
  select t.dtime,t.locid,t.vtid 
 from Transaction_tbl t where Tbarcode=@carid
end

where ever you want your first procedure to be executed, then set pass @option as 1 to the procedure that's all. OR leave it to assume the default 0 value to execute the sec procedure.
