'method not implemented', __FUNCTION__ );
* Returns information about a table or a result set
* The format of the resulting array depends on which <var>$mode</var>
* you select. The sample output below is based on this query:
* SELECT tblFoo.fldID, tblFoo.fldPhone, tblBar.fldId
* JOIN tblBar ON tblFoo.fldId = tblBar.fldId
* <kbd>null</kbd> (default)
* [flags] => primary_key not_null
* [flags] => primary_key not_null
* <kbd>MDB2_TABLEINFO_ORDER</kbd>
* <p>In addition to the information found in the default output,
* a notation of the number of columns is provided by the
* <samp>num_fields</samp> element while the <samp>order</samp>
* element provides an array with the column names as the keys and
* their location index number (corresponding to the keys in the
* the default output) as the values.</p>
* <p>If a result set has identical field names, the last one is
* <kbd>MDB2_TABLEINFO_ORDERTABLE</kbd>
* <p>Similar to <kbd>MDB2_TABLEINFO_ORDER</kbd> but adds more
* dimensions to the array in which the table names are keys and
* the field names are sub-keys. This is helpful for queries that
* join tables which have identical field names.</p>
* [ordertable] => Array (
* The <samp>flags</samp> element contains a space separated list
* of extra information about the field. This data is inconsistent
* between DBMS's due to the way each DBMS works.
* + <samp>primary_key</samp>
* + <samp>unique_key</samp>
* + <samp>multiple_key</samp>
* + <samp>not_null</samp>
* Most DBMS's only provide the <samp>table</samp> and <samp>flags</samp>
* elements if <var>$result</var> is a table name. The following DBMS's
* provide full information from queries:
* If the 'portability' option has <samp>MDB2_PORTABILITY_FIX_CASE</samp>
* turned on, the names of tables and fields will be lower or upper cased.
* @param object|string $result MDB2_result object from a query or a
* string containing the name of a table.
* While this also accepts a query result
* resource identifier, this behavior is
* @param int $mode either unused or one of the tableInfo modes:
* <kbd>MDB2_TABLEINFO_ORDERTABLE</kbd>,
* <kbd>MDB2_TABLEINFO_ORDER</kbd> or
* <kbd>MDB2_TABLEINFO_FULL</kbd> (which does both).
* These are bitwise, so the first two can be
* combined using <kbd>|</kbd>.
* @return array an associative array with the information requested.
* A MDB2_Error object on failure.
* @see MDB2_Driver_Common::setOption()
