I believe you are _asking_ for one thing and
showing an _example_ of another.
Going by the example, the first returned row shows
data from field 'value' in table T2. The second shows
data from field 'value' in table T1 as there is no
matching row in table T2. To do that, you could use
the COALESCE function:
...select id, type, COALESCE(T2.value, T1.value)...

Thanks,
Don

Hi
I need some suggestion with sql query
I have 2 table
T1 which has columns
id, type, value
And
T2 has columns
id, type, value, user

T1 has data as below
id Type value
schd test abc
schd test1 abc1

T2 has data
id Type value user
schd test xyz myid

I want to write a SQL to get data from T1 if there
is
no record in T2, The value in T2 may be different
from
T1.

So my result after the query will be
(i dont need user id)
id Type value
schd test xyz (this comes from T2)
schd test1 abc1 (this comes from T1)

Any suggestions

Ashish
