Hi,
I want to change 2 columns in the same table from numeric into int. Can
I do this without deleting the old table and creating a new one? Data
stays the same..
Thanks

TIP 5: Have you checked our extensive FAQ?
Hi,
I wonder if it is possible to remove a field of a table ?
I haven't found anything about this into the reference manual.
Can I do something like that ?:
ALTER TABLE table
DROP COLUMN column;
Thanks
Rachel

Dear All,
I want to dreate a delete cascade in children tables. The primary key of
parent table is oid, so when I create parent table, there is no apparetly
key word "primary key". The problem jumps out.
When I create child table using columnn constraint on delete, the SQL says:

Actually, the ORDER BY *must* be replaced by GROUP BY since it is an
aggregate query.
I have implemented it, and the results are startling, I get the same value
repeated for all projects
i.e.:
AS1 AS1-AJAX/SALEM SIDE 3 0 6 7 30 0 216 240
AU3 AU3-RIVERIDGE/AURORA 3 0 6

In a PLPGPSQL script, once you know count(*) try
execute ''select * from table limit '' || int4( theCount / 4);
If you want numbering, create a sequence and add nextval() to the query.

Here's a puzzler:
Given a query that returns rows ranked by some criteria, how can I write
another query around it that will give me the (say) first quartile (top
25%)? Another way of putting it is: if I have rows that look like this:
aaa | 1251
aba | 1197
cax | 1042
... | ...
axq | 23

I would personnaly like this feature (assigning a composite from another
similar composite) to be added to PLPGSQL. Another nice feature would be
to able to insert a composite into a table without have to name all
atributes.

Dependent on what you need:

Consider the following PLpgSQL code fragment
FOR this_record IN
