Creating "Conditional" Sums in Query

Creating "Conditional" Sums in Query

Creating "Conditional" Sums in Query

I have a table that has the following fields:


I want to get a sum of sales grouped by <customernum>.  Should be simple enough, except that the <tickettotal> field is always stored as a positive value, even for credits (as indicated by <transtype>="CRD").  What I want is the total sum of sales minus the sum of credits by customer.

Is there a way I can put this in a SQL query and have my server do the work, or do I have to do this on the client end?

BTW, I'm running Pervasive.SQL 8.6.

RE: Creating "Conditional" Sums in Query


You could try using the IF statement with your select.  The IF command works a bit like the CASE command in SQL Server.

SUM(IF (TransType = 'CRD',
TicketTotal * -1,
FROM <NameofyourTable>

Hope this helps,
