Tags: SQL

Select 'RET' as type, entry_date, Amount, Description, '' as Status from Client0.dbo.invoice_retainers
where Client_id = 1

Select 'INV' as type, invoice_date as entry_date, cpTotalDue as Amount, Invoice_Number as Description, status

UNION ALL
Select 'PYMT' as type, payment_date as entry_date, Amount, Reference as description, '' as status
