[ADMIN] parametrized query

2004-04-28 Thread Ben Kim

I tried but couldn't find an answer if this is possible in psql.

Create a file named test.sql
select * from mytable where id = ? (or use $1, $2...)
Then in psql do
\i test.sql 337

to achieve the same effect select * from mytable where id=337

as I would in perl
$sth = $dbh - prepare (insert into mytable values (?, ?, ?))

Is writing a function the only way? Is there another way that can be done
without writing a function?

Thanks,
Ben Kim

Put it into a shell script like

echo select * from mytable where id = $1; | psql $DBNAME

That can be executed using the shell function in psql

\! [COMMAND]   execute command in shell or start interactive shell
