I have a phonenumber_table with two fields: phonetype and phonenumber. The different phone types are business, fax, etc. When I join this table with my company_table and select phonenumber, I get duplicates because of the different phone types. How can I get both fax number and phone number in the layout (phonenumber as Phone_Number, phonenumber as Fax_Number) whichout duplicate records? My current query is below. Thanks.

select company,phonetype, phonenumber as Phone_Number, phonenumber as Fax_Number, status
from company_table
inner join phonenumber_table on company_table.ID = phonenumber_table.ObjOwner_ID
where status = 'Active'

You need to join to the table for each type.
select c.company, p.phonenumber as Phone_Number, fax.phonenumber as Fax_Number, status

from company_table c

  left outer join phonenumber_table F

   on c.ID = phonenumber_table.ObjOwner_ID

   and f.phoneType = 'FAX'

  left outer join phonenumber_table p

   on c.ID = phonenumber_table.ObjOwner_ID

   and p.phoneType = 'PHONE'
 

where status = 'Active'
