Hi All Im hoping someone has an answer for this mystery. I have a stored procedure, which queries a table, of about 400-000 records, into a RECORD, ordered by three columns. I am using a conditional INSERT, UPDATE command, basedon evaluating the last record.column, against the new record.column, to ascertain whether it requires, an UPDATE or INSERT.

Im trying to assign the value of a dynamic variable, to a variable.
How is this done in PostgresQL. Is this allowed in Postgres Procedural Language

variable1:= quote_ident('variable_'||quote_literal(year));

Title: ++ [GENERAL] PLPGSQL
Adding to that.
Can you assign the value of a dynamic record value.
For example
If I have written dataset returned, into a record.
I now want to call on a particular column value from the first row.
The column name is dynamic.
Can I use something like this
sales_month1_x := RECORDNAME.quote_ident('month1_'||quote_literal(yr2));
Where the value of
RECORDNAME.month1_2004
is assigned to sales_month1_x
Is this possible.
It doesnt look right, in that I have referenced RECORDNAME.quote_ident
That should bomb out..
how would I reference the dynamic column of the record.
Thanks in advance.

You will then need to construct the SQL statement using || (concatenate) and execute it using EXECUTE. http://www.postgresql.org/docs/current/static/plpgsql- statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN Does this help?

I doubt you'll see much real difference. Your real bottleneck will be I/O. You might be able to save something by using COPY out and then back in. If it's a lot of data I would definately try that, because it's got a lot more chance of helping you. Or you could use a server side function rather than doing the work in the client. contrib/dblink may be able to help you a lot. However, your question made it sound like the tables were in the same DB already and just in different schemas? If that's the case, you can just select one table into another and avoid all that unecessary overhead. Regards, Jeff Davis

I'm gladto hear yougot

In explanation to my response:
the pg_class internal table lists all the
relationships in the database.
relkind='r' means that the relation you are
looking for is a table (relation), I believe that will also find
views.
relname is the name of the object if your table
is called parts
select * from pg_class where relkind='r' and
relname='parts' will give you the pg_class record for the table if it exists
and nothing if it doesn't.
you could also do a select count(*) or select 1
In any case if there is a resultset the table exists and if there is no
resultset the the table does not.
Using the pg_tables view is a better idea in any
case, as it is cleaner.
