I have three identical tables, t1, t2, t3
Each table contains a complete list of files on a particular server.
One of the fields in each table is owner (the owner of an individual
What is the SQL syntax to get a list of all the files owned by a
single user "abcde" from the three tables ?
I can do this in three statements:
Select * from t1 where t1.owner = "abcde";
Select * from t2 where t2.owner = "abcde";
Select * from t3 where t3.owner = "abcde";
The question is how can I do this in one statement?
Here is my first attempt:
Select * from t1,t2,t3
where t1.owner = "abcde"
and t1.owner = t2.owner
and t2.owner = t3.owner
This fails to give the correct answer.
select * from (t1 INNER JOIN t2 on t1.owner = t2.owner) INNER JOIN t3
on t3.owner = t1.owner
This also fails to give the correct answer.
