I am reading through HeadFirst SQL (an OReilly book) which uses specific MySQLisms in its examples. I use postgres on our databases. Some examples are easy to work around, some are not . Is there a rosetta stone (table of commands in one and equivalents inthe other) available? In particular, MySQl seems to have richer string functions to parse out sub strings and als trim a string for automatic table insertion from long multifield strings. Thanks. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
