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'"
i'm sure this has an obvious solution but i can't seem to find it.
any suggestions are appreciated.
regards,
yusuf
