Re: Suggestion with SQL query

Hello Ashish,

Here is the solution for your sql question : -

SELECT ID, "TYPE", "VALUE" FROM T2
WHERE ID IN (SELECT ID FROM T1) AND
TYPE IN(SELECT TYPE FROM T1) AND
VALUE NOT IN (SELECT VALUE FROM T1)
UNION
SELECT ID, "TYPE", "VALUE" FROM T1
WHERE TYPE NOT IN (SELECT TYPE FROM T2) AND
VALUE NOT IN (SELECT VALUE FROM T2)

This will give you the following output:

OUTPUT
ID TYPE VALUE
schd test xyz
schd test1 abc1

I think this is what you want to achieve correct from T1 & T2 Tables.

Subject: Suggestion with SQL query


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
