Raven1313 Posted June 21, 2012 Share Posted June 21, 2012 I'm trying to select PVOL (a number) by desc to get the top 5 values of that column. But I don't get the top 5 values of PVOL... I just get the highest which is LESS than 1,000,000 all the numbers above 1mil don't show up. select PLAST,PREF,POPEN,PCLOSE,PBID,PVOL,PVALUE,PASK,TICKER from hist_sec where DATE(PDATE) = DATE(NOW()) and PVOL != '' order by PVOL DESC limit 0 , 5; How do I select where I also include the numbers above 1 mil?

litebearer Posted June 21, 2012 Share Posted June 21, 2012 You need to modify your table. the fields that contain values that are in reality numbers should NOT be varchar Link to comment https://forums.phpfreaks.com/topic/264543-select-by-desc-doesnt-work/#findComment-1355703 Share on other sites More sharing options...
Raven1313 Posted June 21, 2012 Author Share Posted June 21, 2012 What should I change VARCHAR to? Link to comment https://forums.phpfreaks.com/topic/264543-select-by-desc-doesnt-work/#findComment-1355706 Share on other sites More sharing options...
Barand Posted June 21, 2012 Share Posted June 21, 2012 If they don't have decimals then INT. If they have decimals then something like DECIMAL(12,2) assuming 2 dec places. Also don't store the commas, format the numbers on output. This is the result of sorting nubers DESC in a varchar field +----------+ | title | +----------+ | 60000 | | 50000 | | 40000 | | 15000000 | | 12000000 | | 1000000 | +----------+ Link to comment https://forums.phpfreaks.com/topic/264543-select-by-desc-doesnt-work/#findComment-1355711 Share on other sites More sharing options...
