Question

I have two tables.

My first table is called as WORLD and this table have a column named PEOPLE. In PEOPLE table I have both women’s and men’s names.

My second table is called as MEN and this table has a column named NAMES. It consists of men’s names.

What I want to do is by comparing those two tables finding women’s names and adding them to a column named “WOMEN” in the WORLD table.

WORLD.PEOPLE             MEN.NAMES

John                John
Joe                 Alan
Jessica             Michael
Martin              Martin
Alan                Adam
Eva                 Joe
Mary                

What I want to have is:

WORLD.PEOPLE             WORLD.WOMEN

John                Jessica
Joe                 Eva
Jessica             Mary
Martin              
Alan                
Eva                 
Mary                 

I tried using this statement:

SELECT People FROM WORLD WHERE (People NOT IN(SELECT Names FROM MEN)))

However this only gives result, it doesn’t update the WORLD table.

What should I do?

Answer 1

You should try to Create a new table and add the values there and then drop the WORLD table.
I guess you just want to work on one single database, but i can’t think any other easier way. With insert you will get null values so it won’t be practical. You can try what i said.
