I have the following statement:select chart_of_accounts.accountname as Account, concat('$',format(coalesce(sum(sales_journal_entries.debit),0),2)) as Debit, concat('$',format(coalesce(sum(sales_journal_entries.credit),0),2)) as Credit, concat('$',format(coalesce(sum(sales_journal_entries.credit),0)-coalesce(sum(sales_journal_entries.debit),0),2)) as Balance from sales_journal_entries left join sales_journal on sales_journal.journalID=sales_journal_entries.journalID left join chart_of_accounts on chart_of_accounts.accountID=sales_journal_entries.accountID where sales_journal.date > '2008-12-31' and sales_journal.date < '2010-01-01' group by sales_journal_entries.accountID order by Balance asc; and I'd like the output to be sorted by the Balance according to the numberic value, but it is sorting by the string result. I tried abs(Balance) but I get the following error: 1247 Reference 'Balance' not supported (reference to group function) I'm not sure I understand the error.
Balance is the result of a string operation (concat), and abs is a numeric function that won't work on strings.
You should add a field to the result with the numerical value of Balance, and then sort on that.
