Hello everyone,

I have two tables t1 and t2
table t1--

id     name
1       a
2       b
3       c
4       d
5       e

table t2 --

id     name
2       c
3       r
5       z

i want output using a single line query as :

id    name
1      a
2      c
3      r
4      d
5      z

that is when the id column matches in table t1 and t2 then it should select name from table t2 else from table t1

i have done this using temporary tables..but i want it in a single line query

please help me out..

thanks & regards

Good that I refreshed before posting. This is exactly the same query I have written. And I think it should do the job. 5!
