| sreejith writes "I have 3 columns say a1,a2,a3.if I enter some strings on a1 and a2,then a3 should display the concatenated result of a1 and a2. I want a3 should be updated immediately after I enter values in a1 and a2 and press the down arrow key. I have to get the a3 column filled with out using the run button. Is there any solution?" |

Here's how you can use a computed column, as nr suggested, but I agree with madhivanan - do this when you select the results.declare @t table (a1 varchar(20), a2 varchar(20), a3 as a1 + a2)insert @t (a1, a2) values ('hello ', 'world')select * from @t/*resultsa1 a2 a3 -------------------- -------------------- ---------------------------------------- hello world hello world*/Ryan Randallwww.monsoonmalabar.com London-based IT consultancy Solutions are easy. Understanding the problem, now, that's the hard part. |
