The SQL Module module provides the RXML programmer with three tags for executing SQL queries; <sqloutput>, <sqltable> and <sqlquery>. All three connect to a SQL database and execute an SQL query, the only difference between them is how the result from the query is handled.

Default SQL-database host

The database URL to use by default in the RXML tags. If the correct database URL is specified here with username and password, these variables do not have to be specified in the RXML tags on the pages.

However, this only works if only one database is used. Connecting to more databases requires the SQL Databases module to be installed.
