Swati is cool. buth her queries are correct. you can either
take rowid >with subquery fetching minimum (rowid) else
Rowid < with subquery fething maximum (row id)
DELETE FROM <table_name> T1
WHERE T1.ROWID > (SELECT MIN(T2.ROWID)
FROM <table_name> T2
WHERE T2.<common column name> = T1.<common
column name>)
----------------------------
DELETE FROM <table_name> T1
WHERE T1.ROWID < (SELECT MAX(T2.ROWID)
FROM <table_name> T2
WHERE T2.<common column name> = T1.<common
column name>)
Good job Swati.. :)
