Re: [DUG]: Paradox SQL - Group totals as % of Grand total

[Mike Osborne]

Mark The following works in Database Desktop (v7.0) - haven't verified how it goes in Delphi.   Table has Amount and ExpType (among other things) in an Expenses table. The following SQL provides total expenses by type and as percentage of total and has a grand total at the end.   select "zzzzzz", sum(amount), 100 from expenses e3 union select exptype, sum(amount), (sum(amount)/(select sum(amount) from expenses e2) * 100)  from expenses e1 group by exptype   The "zzzzzz" (in my query) managed to put that line (grand total) at the end - it could be a column you don't show in the report. The 100 in first select sets up the column - and ensures percentages add up to 100 at the end <g>.   HTH Mike ----- Original Message ----- From: Mark Howard To: Multiple recipients of list delphi Sent: Wednesday, September 26, 2001 11:47 AM Subject: [DUG]: Paradox SQL - Group totals as % of Grand total Hi   Using SQL I want to assemble a dataset (to be used by a Quick Report) that will allow me to express each group total as a percentage of the grand total.    I can't calculate the percentage at the group level in the report because we don't have the total until the end, so it seems that I need to have the grand total read into the dataset.   Are there any tricky ways of achieving this? or is there no alternative to just doing a double pass through the dataset?   TIA   Mark
