Answer / yuvaevergreen

Adding to the above,DBC.Indexes can be used to find whether
the index is PPI or join or hash or primary key.

Answer / prasanna

Hi Innocent,

Appreciate for your answer.

But one small correction is that tablename and database name columns are present in DBC.indices itself where as you had went for a join condition with dbc.tablesize.

so without join condition we can take both tablename and database from dbc.indices table.

Thanks
Prasanna.
