What have you tried? Where are you stuck?

SELECT t1.PK, t1.id, t1.status, t2.status status2
FROM TableName t1 INNER JOIN TableName t2 ON t1.id = t2.Id AND t1.PK<t2.PK
WHERE status='01' and status2!='02'

SELECT  *
FROM    Table1 t1
WHERE   status = '01'
    AND NOT EXISTS
    (
    SELECT  1
    FROM    table1 t2
    WHERE   status = '02'
        AND t1.id = t2.id

Hi,

Check this...

SQL

Select * from table_1 Where status = '01' and id not in (SELECT distinct id from table_1 Where status = '02')

Hope this will help you.

Cheers
