​Hello ,

I have a table called Member consisting of Columns MemberName, MotherName, and EmploymentStatus. I would like to create a query which gives me MemberName, MotherName, and EmploymentStatus in which the Mother's all Daughers are Emplpyee . In my table below I want row 1 as a result of the query.

You need to create another table with mother daughter relationship. In real life, your table above will have actual names! It will be pretty confusing who is whose daughter without a separate table. Then, you can use foreign key to link that table with this table.

Hi Ujl,
Thank you for your reply.

I already have a table in this format and it is not feasible to make another table quickly. Can someone suggest the query for the same table, please?

SELECT * FROM Member
WHERE MotherName = 'GrandMother1' AND EmployementStatus = 'Employee';

The above query will bring row 1 as a result.

Hi ujl,

Thanks for your reply.

In my table thousands of records where only some members of the same mother are employed.
The query should be able to fetch the records of all mothers whose daughters are employed.

SELECT * FROM Member

not optimized...

SELECT * FROM phonesTable pt1
WHERE pt1.EmployeeStatus = 'Employee'
AND pt1.MemberName IN (select pt2.MotherName from phonesTable pt2 where pt2.EmployeeStatus = 'Employee')
AND pt1.MemberName NOT IN (select pt3.MotherName from phonesTable pt3 where pt3.EmployeeStatus = 'Unemployee');
