Hallo,
Anyone whom could g�ve me some good help on this.
I have a table with one field, called Company_id
Like this
Company_id
16
45
50
In table 2 I have this field and values:
Company_id Lev_id Vare_id
16 45 56
34 10 20
67 10 20
45 15 30
50 12 12
I would like to from table 2 do a select and find the Company_ids from table1 and find
out the responding lev_id and vare_id in table2and then insert them into a new
table(table3) so it would look like this:
Company_id Lev_id Vare_id
16 45 56
Anyone whom could give me some help on this how to write the sql- query.
I have tried with this sql query. What is wrong?
insert into table3(company_id,lev_id,vare_id)
select company_id,lev_id,vare_id from table2 where vare_id = 56
(where exists select company_id from table1)
Thanks in advance
Roland
