I have a database which have 2 columns
username and refBy
username -> its a user whose admin is refBy column
i have 3 level data
mdis (username) -> rajdeep (refBy)
dis (username ) -> mdis (refBy)
ret (username) -> dis (refBy)
As you can see here rajdeep is creator of mdis ,
mdis is creator of dis ,
dis is creator of ret ,
I need a query so that if i fetch rajdeep records it will give details mdis , dis and ret alongs with its creator , its like grandfather details , if i select grandfather name it will give all his son and son of son details along with father name .
I tried this query "select username,refBy from refByTmp where refBy in (SELECT username from refByTmp where refBy='rajdeep') or refBy='rajdeep'"
But its showing only 2 level data .
