How do I...

• get records from table
• get records from given table where <conditions> (how to specify equals, not equals <, >, <=, >=, in/not in etc)
• get records from table where order by

• how to use the iterators, and when

• new (create) record
• read in record
• delete record
• amend record

• calling stored procedures...sometimes its quicker/necessary to have SPs

• OO queries - background, how to build one, when is good to use one, when isn't.

• How to write your own queries in a gateway, where to write them etc.
• How to deal with subqueries i.e. can reactor do them, or is it something you need to write a method for in a gateway etc.
