displaying related rows from a table

Dear All
I want to write an SQL program that would display all identical fields from a table, for eg if the table has 5 columns and two rows have same values for all these five columns , the sql statement should be able to find all such matching rows in the table and display them to the user
How would i go about doing this
thank yo
harshaharsha,
You can code a self-join on the table.
Ex. SELECT A.* FROM mytable A JOIN mytable B ON
a.col1 = b.col1 and a.col2 = b.col2 and b.col3 = b.col3
and ....
Might be other ways, but this should work for you.
