Create a SQL query at runtime in Application Module

In your application module implementation file, you could use getDBTransaction().createStatement() method to execute a sql query at run time.

Note there are three SQL statement types available in the DBTransaction interface: statement, callableStatement and preparedStatement.

Here is the snippet of coding in your application module file:
