hi i am to get a resultset based on values in two columns. the columns: codes, char(1) - holds various characters. date, datetime - holds various dates. i am to get all rows except the ones that have codes 'c' and 'g' and also have a date older than march 3rd 1977. (i am to get the rows that have codes 'c' and 'g', and a date that is march 3rd 1977 or after.) hints would be fine

i found a solution select codes, date from codetable where (codes not in ('c', 'g') or date > '19770303')
Originally posted by tormod eriksen: if i set 'and' instead of 'or', won't that give results with dates from march 3rd 1977 onwards only, for all codes (not only 'c' and 'g') ?
Just the opposite. Your current query ( with OR ) will not only omit all rows with a 'c' or a 'g' but will also omit omit rows with a date > '19770303'. If you want to omit the rows with either a 'c' or a 'g' as well as a date > '19770303' then you must use AND. Jamie [ May 30, 2002: Message edited by: Jamie Robertson ]
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
