Question

Need a cursor to update a value from another stored procure and updates only selected values

I have the following:

DECLARE upd_cursor CURSOR FOR
SELECT * FROM Terr
WHERE Text = "RightT" ;

OPEN upd_cursor;

-- Perform the first fetch.
FETCH NEXT FROM upd_cursor;

-- Check @@FETCH_STATUS to see if there are any more rows to fetch.
WHILE @@FETCH_STATUS = 0
BEGIN

 exec usp_Gent  @valback OUTPUT; 
 update Terr  
 set Text = @valback

FETCH NEXT FROM upd_cursor;
END

CLOSE upd_cursor;
DEALLOCATE upd_cursor;
GO

In my case, it updates all of the field in the table. What am I doing wrong

Answer 1

If you really wanted to do a row by row update you could use CURRENT OF syntax. This would be the case if your call to the stored procedure returned different results on each.

e.g.

     update Terr  
     set Text = @valback
     WHERE CURRENT OF upd_cursor
