示例1: select
/**
* Retrieves information from the database.
* Select utilizes parameters set previously in the object
* (i.e. addWhere, addColumn, setLimit, etc.)
* You may also set the "type" of result: assoc (associative)
* col (columns), min (minimum result), max (maximum result), one (a single column from a
* single row), row (a single row), count (a tally of rows) or all, the default.
* All returns an associate array containing the requested information.
