use array/variable in sql-query

Question

I\'m sure there is a way to do it but I don\'t know it anymore...

I have one big table with all the data.

In the table I have rows with information

Answer 1

you could try this: SELECT DISTINCT A.Groupname, B.name FROM tablename A JOIN tablename B ON A.GroupID = B.GroupID

Answer 2

Try this:

SELECT T2.name,T1.groupName
FROM Table1 T1 INNER JOIN
Table1 T2 on T1.groupID=T2.groupId2
WHERE T2.category=1
