I need help on #2 and #3:

1) select data from a table, stored the STD_ID in the temp table.

2) need to execute anther stored procedure 'GET_STD_INFO ' pass in the STD_ID, it will return  columns included the following:
STD_ID, STD_NAME, ACTIVE_IND AND CLASSES_TOTAL, etc...

3) need to update the temp table with the return columns of STD_ID, STD_NAME, ACTIVE_IND AND CLASSES_TOTAL



DECLARE @TMP_TEST table
(
      STD_ID                  INT,
      STD_NAME            VARCHAR(50),
      ACTIVE_IND            CHAR(1),
      CLASSES_TOTAL            INT
      )



INSERT @TMP_TEST
      (
      STD_ID
      )
SELECT  DISTINCT
      TOP 1 STD_ID
FROM STUDENT_TB
ORDER BY ACTIVE_YEAR


what is the best way to do this?

thank you,

I am running in  MS SQL server 2010.

this is NOT a student assignment, the example above just to make it easy to understand ( at lease if for me), and it part of what I need to do for work.

the way you described the question seems suspecious. thats why I asked you


declare @rows int , @stdid int 


DECLARE @TMP_TEST table
(     i int identity , 
      STD_ID                  INT,
      STD_NAME            VARCHAR(50),
      ACTIVE_IND            CHAR(1),
      CLASSES_TOTAL            INT
      ) 

CREATE TABLE #tmp
(    
      STD_ID                  INT,
      STD_NAME            VARCHAR(50),
      ACTIVE_IND            CHAR(1),
      CLASSES_TOTAL            INT
      ) 

INSERT @TMP_TEST
      (
      STD_ID
      )
SELECT  DISTINCT
      TOP 1 STD_ID
FROM STUDENT_TB 

select @rows = @@ROWCOUNT

while @rows > 0 
BEGIN
	SELECT @stdid =  std_id 
	from @TMP_TEST 
	where i = @rows 
	
	SELECT @rows = @rows - 1 
	insert into #tmp
	exec GET_STD_INFO @stdid 
END 

update t
set std_name = d.std_name, 
    active_ind = d.active_ind,
    Classes_total = d.classes_total
FROM @TMP_TEST t
inner join #temp d on t.STD_ID = d.std_id

Hi aneeshattingal,

THANK YOU FOR HELP!!!  I think will just make it easy to ask the question.

I have 2 questions :  

1) can the #tmp be @tmp as table variable ?
2) what happen is the get_std_info return more columns then the #tmp/@tmp table list columns?  do I need to list all the columns return from get_std_info in the #tmp/@tmp?



Thank you very much for help.

Hi,

yes the #temp table can be used as @temp variable and you might need to tweak the get_std_info to return only the columns that you like to insert into the Temp table.

I would take the logic of get_std_info and join the @TMP_TEST  table, rather than loop thru each id and call the sp, but it depends on the complexity of your stored procedure; Other option will be conver get_std_info  to a function and join with @TMP_TEST  table.
