I need to Join table t1 with t2 and t3

select a,b,c ,d from t1
left join t2 on t1.a = t2.a
left join t3 on t1.b =t3.b

I am getting too many records . Total records should only the number of records in t1. What am I doing wrong?

Not necessarily. If there are multiple rows in t2 or t3 with the same join value, you will get a row for each one.

Post sample data.

That was it . One of the joining tables had multiple rows !
