Thread: very odd behavior

very odd behavior

From

I have 7.1

Can someone take a look the following
and tell me why I'm getting errors?
I'm completely baffled!
----------------------------

what=> create table bla(desc text,def text,data text);
ERROR:  parser: parse error at or near "desc"
what=> create table bla("desc" text,def text,data text);
CREATE
what=>

Thanks everyone for very quick reply.

The reason I found odd was I had
created another able with the same
field name and don't recall having
problems at the time with 7.0.3.
Or did I get the same problem
but I just forgot?  I dumped
and reloaded 7.0.3 table to 7.1
without problem though.

desc is a reserved word (descending, ascending, having,  from, etc...),
as in:
select * from foo order by col_a desc;
That is why you need the double quotes.

desc is used to mean descending, as in "order by foo desc". If you enclose
that keyword in quotes, then the parser knows you are using it as a field
name and doesn't wonder about what should be descending..

desc is a reserved keyword (used in ORDER BY to indicate descending order)..

You can use keywords as field names though you have to put the in quotes (as
you found out!).
