Title: query with table alias
Hello,
I think I have found a query problem when the query has an alias for a table and use alias item and table name.
I ilustrate the problem with a simple table and query.
prr=# create table foo (c1 int2, c2 int2);
CREATE TABLE
prr=# insert into foo

If you alias a table, you can only reference the table using the alias.
It is in effect renamed: foo is no
Title: query with table alias
The
correct query would be "select f.c1, f.c2 from foo f;" if
you want to use alias

prr=# select foo.c1, f.c2 from foo f; -- Incorrect result
The result of the select foo.c1, f.c2 from foo f isn't correct, it do
a cartesian product of foo table.
foo is aliased to f, so there's no table named foo in the from clause.
By default postgres tries to add the missing table name, so
If 2 days are equal for color red, you still would get 2 rows returned.
Maybe the below is accurate.

FROM giventable g
WHERE g.color = 'red'
AND g.date =
(SELECT MAX(g2.date)
FROM giventable g2
Hello all,
I have accidently :-) found 'initlocation' and now I like to
know, how many secondary database i can create.
I like to do that, because I have a Virtual Webserver and for
each VirtualHost I have a local $USER. Now I like to create
seperatly secondary databases for each $USER/VHost.

IIRC, the initdb is recommended, but not required. It can be done
without an initdb too.
As many as you have disk space for I guess. You might need one
postmaster per location but I'm not sure about that, check the docs...

The my2pg.pl script creates custom functions that help with the MySQL
set column type. I can't figure out how to use the functions once I
have the database migrated into Postgres.
Can someone please explain how to make use of them?
In MySQL, the table exists:

How does one embed a sub-query lookup to one table in order to
replace a foreign key id number with it's name in a SELECT on a
second table?
i.e.: given the following two tables, I want to replace the color_id
of 1
with the color_name 'red.' (The SQL to create the two tables follows
below.)
something == otherthing is a boolean expression, you are asking the
database to compare both values, u.color_id is not equal c.color_name,
that's why you get 'f'.
I guess that you want to replace the color_id from users by the
corresponding color_name from colors:
SELECT
c.color_name,

You're talking about joins.
