Hi,
I need to trim whitespace off of a whole column and replace the existing
values with the trimmed ones.
This isn't working
update mytable set id = trim(id);
I'm not sure of the correct syntax. Help appreciated.
Mike
The trim function needs to be told what sort of trim to do --
Following the 9.1 manual (you did not specify which version of postgres you are
using) try:
UPDATE mytable SET id = trim(both ' ' from id).
Actually not:)
test=> SELECT length(trim(' test '));
length
--------
4
(untested)
See<http://www.postgresql.org/docs/9.1/static/functions-string.html>
HTH,
