- * The main "DB" class is simply a container class with some static

- *
- * The object model of DB is as follows (indentation means inheritance):
- * <pre>
- * DB           The main DB class.  This is simply a utility class
- *              with some "static" methods for creating DB objects as
- *              well as common utility functions for other DB classes.
- *
- * DB_common    The base for each DB implementation.  Provides default
- * |            implementations (in OO lingo virtual methods) for
- * |            the actual DB implementations as well as a bunch of
- * |            query utility functions.
- * |
- * +-DB_mysql   The DB implementation for MySQL.  Inherits DB_common.
- *              When calling DB::factory or DB::connect for MySQL
- *              connections, the object returned is an instance of this
- *              class.

-     * These modes are bitwised, so they can be combined using <kbd>|</kbd>
-     * and removed using <kbd>^</kbd>.  See the examples section below on how
-     * to do this.
-     *
-     * <samp>DB_PORTABILITY_NONE</samp>
-     * turn off all portability features
-     *
-     * This mode gets automatically turned on if the deprecated
-     * <var>optimize</var> option gets set to <samp>performance</samp>.
-     *
-     *
-     * <samp>DB_PORTABILITY_LOWERCASE</samp>
-     * convert names of tables and fields to lower case when using
-     * <kbd>get*()</kbd>, <kbd>fetch*()</kbd> and <kbd>tableInfo()</kbd>
-     *
-     * This mode gets automatically turned on in the following databases
-     * if the deprecated option <var>optimize</var> gets set to
-     * <samp>portability</samp>:
-     * + oci8
-     *
-     *
-     * <samp>DB_PORTABILITY_RTRIM</samp>
-     * right trim the data output by <kbd>get*()</kbd> <kbd>fetch*()</kbd>
-     *
-     *
-     * <samp>DB_PORTABILITY_DELETE_COUNT</samp>
-     * force reporting the number of rows deleted
-     *
-     * Some DBMS's don't count the number of rows deleted when performing
-     * simple <kbd>DELETE FROM tablename</kbd> queries.  This portability
-     * mode tricks such DBMS's into telling the count by adding
-     * <samp>WHERE 1=1</samp> to the end of <kbd>DELETE</kbd> queries.
-     *
-     * This mode gets automatically turned on in the following databases
-     * if the deprecated option <var>optimize</var> gets set to

-     * + fbsql
-     * + mysql
-     * + mysqli
-     * + sqlite

-     *
-     * This mode gets automatically turned on in the following databases

-     * <samp>portability</samp>:

-     *

-     * makes certain error messages in certain drivers compatible
-     * with those from other DBMS's
-     *
-     * + mysql, mysqli:  change unique/primary key constraints
-     *   DB_ERROR_ALREADY_EXISTS -> DB_ERROR_CONSTRAINT
-     *
-     * + odbc(access):  MS's ODBC driver reports 'no such field' as code
-     *   07001, which means 'too few parameters.'  When this option is on
-     *   that code gets mapped to DB_ERROR_NOSUCHFIELD.
-     *   DB_ERROR_MISMATCH -> DB_ERROR_NOSUCHFIELD
-     *
-     * <samp>DB_PORTABILITY_NULL_TO_EMPTY</samp>
-     * convert null values to empty strings in data output by get*() and
-     * fetch*().  Needed because Oracle considers empty strings to be null,
-     * while most other DBMS's know the difference between empty and null.
