Hi all,
I start working with enumerator types and I am wondering, if my enumerator can
later be adjusted. E.g. if I would like to add another label.
Is it allowed just to add another entry to pg_enum? How is the enumerator then
sorted (i.e. enum_last() )?
Is it possible to alter the labels of

AFAIK you can't. Each enum is a own type. Use a lookup-table instead and
use enum's only for real static
I recommend switching to aqua data studio
I can query mysql, postgres, db2, oracle with the same tool

Hello,
I have a dilema and I was hoping someone here may offer guidance or assistance.
I bet this is a very simple question for someone out there but I am having
problems coming up with a solution. Here it is...
suppose I have a field with the following values:
77.1
77.2
134.1
134.2
134.3
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
That field of yours... what type is it?
Is it TEXT? is it a numeric type?
If it's TEXT, why don't you make it say... NUMERIC(/10/, /6///)?

For numeric data types use:
http://www.postgresql.org/docs/8.4/static/functions-math.html
You could then use|floor|(dp or numeric)|| for example:
postgres=# select floor(71.912);
floor
- ---
71
(1 row)
postgres=# select
This is good, however, I need only the numbers to the right of the decimal
point
so if my number if 17.2
I would need one query that would return 17 (your function will do that)
and the second query would return: 2
not 0.2
just 2
Does that make sense?

select 0.341*pow(10,length(0.341::text)-2);
2 is a constat that stands for the '0.' part of the string
representing the decimal part of the number.

For the record if you'd like to use regexp:
select substring('201.123' from $$[0-9]*$$);
and
select substring('201.1232' from $$\.([0-9]*)$$);
