SQlite query - return duplicates

I have two tables the first table has the fields

Id,filemd5

the second table
id,filepath,fileId (this is the id from the first table)

The second table contains several rows that have the same fileId. I need a query to return a list of the rows that have duplicates.


thanks

These queries should do the same thing different ways, i.e. select all rows from your second table (called table2 here) where the fileid field occurs more than once:

select *
from table2
group by fileId
having count(*)>1

select *
from table2 t2
where (select count(*) from table2 where fileId=t2.fileId)>1

If you wanted to include the first table to limit the results to matches between the two tables you could do this:

select t2.*
from table2 t2, table1 t1
where (select count(*) from table2 where fileId=t2.fileId)>1
and t2.fileId=t1.id
