Can anyone assist with some SQL syntax, I have a base query (see below). It basically links to invoices in our ERP application. We have an apa.amount_paid column, but the issue is it appears 1 or many times based on the number of lines in the invoice. Lines represent various elements of the invoice, and subsequently the amount paid column is appearing numerous times based on the number of lines. So if an invoice had 4 lines, I get 4 rows giving me the same amount paid information i.e. £456.77.
I need a way to crunch the results to only show one row per invoice. Can anyone give any pointers. Each invoice can be grouped either by apa.invoice_id or apa.invoice_num. You will have to excuse my knowledge in this area, very new to it and the SQL DBA is off long time sick so trying to tweak certain queries to get what I need. I fear a group by won’t give me what I need either with the columns currently in the select, and a group by with SUM on the apa.amount_paid won’t work either and would give inaccurate data and total the same apa.amount_paid amount several times over (i.e if 4 lines 4x the apa.amount_paid).
The troublesome rows are aida.LINE_TYPE_LOOKUP_CODE, aida.distribution_line_number, which is where it breaks the invoice down into several rows. Any pointers?
to_char(apa.amount_paid,'9999999.99') as amount_paid,
apa.doc_sequence_value as "VOUCHER_NUMBER",
aida.invoice_ID, to_char(aida.amount,'9999999.99') as amount,
aida.DIST_CODE_COMBINATION_ID = gcc.CODE_COMBINATION_ID
AND aida.invoice_ID = apa.invoice_ID
AND apa.vendor_ID = ass.vendor_ID
AND gcc.segment2 IN (‘123’,’456’,’789’,’000’)
--AND aida.line_type_lookup_code = 'ITEM'
AND apa.amount_paid > 5000
--AND ass. vendor_type_lookup_code = 'ONE'
order by apa.doc_sequence_value
