Hi,
i want to extract data from an existing PostgreSQL database on
localhost. I tested the ODBC connection with OpenOffice and it works
nice after entering the database user and password.
But i'm still confused to extract the data with Gretl. I connected via
the gretl console to the database named eix with
open dsn=eix user=databaseuser password=password --odbc
and there are no output from the gretl console. how can i access the
data?
You're halfway through. The "open" command establishes the connection.
The actual data retrieval is a job for the "data" command, which stores
the output of an SQL query. Example:
<script>
qry = "select foo from bar"
data myseries query=qry --odbc
</script>
