I have a largeData as table (imported from oracle database). The first column is timestamp (date and time). How can I delete certain lines after time (timestamp). I want to delete the night data, between 22h and 5h. Or can I change what in SQL command? ...FROM "LOGDATEN".DATENLOGGER_SHA WHERE DATUM >= to_date(''2016-07-01'',''yyyy-MM-dd'') AND DATUM < to_date(''2016-08-01'',''yyyy-MM-dd'')order by datum asc']) thanks for your help

Badr, you're going to need to provide a short example so that people can see what you mean by "table" and "timestamp (date and time)".

If you would like to do this processing in MATLAB after you have imported the data as a table, you can use " isbetween " function for creating a logical array which states which datetime entry meets the criteria. You can then filter your table by using this logical array.
