How can I
1. Write a prepared query and
2. Set values at run time and
3. Execute that query for different values.
LOOP
...
...
sql := INSERT INTO MYTABLE VALUES(?, ?);
..
--EXECUTE (sql);
END LOOP;
Regards
Dinesh Pandey

Depends on what language you are using - try interfaces mailing

You don't say what language you want to use, but assuming it's plpgsql,
then for the simple case you can just do:
LOOP
INSERT INTO mytable VALUES (var1, var2);
END LOOP
Now, let's say you wanted to change mytable as well as the values, you'd use
sql := ''INSERT INTO '' || quote_ident(my_table_variable) || ''
VALUES ...etc'';
EXECUTE sql;
Does that help?

Yes you got my problem correctly. I want to change tablename and values at
run time.
Is there any other way instead using "||" (append) ? like prepared
statement.
PREPARE fooplan (int, text, bool, numeric) AS
INSERT INTO foo VALUES($1, $2, $3, $4);
EXECUTE fooplan(1, 'Hunter Valley', 't', 200.00);
Thanks
