Crystal Reports equivalent of 'WHERE'
问题 I'm familiar with SQL but not Crystal Reports. I'm trying to deal with an imported data set with 5 columns: id deathDate giftDate giftAmount Dead 123 2008-01-06 2011-09-08 25.00 TRUE 456 2009-06-08 2011-10-13 10.00 TRUE 789 0 2011-12-04 50.00 FALSE ... I'm trying to do a subquery but can't figure out what the CR equivalent of WHERE in SQL would be. I'd like to do something along the line of: SELECT count(id) from tab1 where dead=TRUE Any suggestions? 回答1: As Conrad and dotjoe have observed,
