One of the things that sucks about SQL is that every databse has a different implementation of SQL.
Port-a-Query is designed to make writing portable SQL queries a bit easier by providing simple helper methods that product the right SQL for your environment.
This project is just something I work on as I need it and it's not meant to be a comprehensize solution. If there's something you'd like added just put in a feature request or send me a patch.
In port-a-query symbols are treated as identifiers (table names, column names, etc.). Strings will be treated as literal strings.
For example the following code
PortAQuery.concat(:first_name, ' ', :last_name)
will produce the following SQL.
MySQL "first_name"||' '||"last_name"
- Port-a-Query is a Ruby on Rails specific gem that uses the database adapter defined by the current environment. There is no method for manually changing the adapter at the moment.
PortAQuery.concat() PortAQuery.quote_string() PortAQuery.quote_identifier()
