greetings all![i just became a member] i have a string data from a view that is a packed field. it contains a date, a time and a user's initials. i'm trying to extract the date portion in a pg 7 view. the data originally came from a ms sql 7 table that has since been converted into a pg 7 table. in the ms sql 7 view the date was extracted as follows: convert(timestamp, substring(creat, 1, 8), 120) = 'createdate' where creat is the packed field from the original table and 'createdate' is the extracted date portion. the data would typically look like: 200111171623XYX. the result is '2001-11-17'. i've reviewed documentation, on line books and several threads in this and related newsgroups and can't seem to come up with a decent solution. i've tried various combinations of this in a pg 7 view: to_date(substr(creat,1,8),'YYYY-MM-DD') = 'createdate' to_date(substring(creat from 1 for 8),'YYYY-MM-DD') = 'createdate' to_timestamp(substr(creat,1,8),'YYYY-MM-DD') = 'createdate' to_timestamp(substrsting(creat from 1 for 8),'YYYY-MM-DD') = 'createdate' and continually get different errors: "bad date external representation 'createdate'" or "bad timestamp external representation 'createdate'"
Your substring-date isn't in 'YYYY-MM-DD' format, but in 'YYYYMMDD' Regards, Tomasz Myrta ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
