Returns the list of tables from the system (quering the DBMSs) It looks up all tables from the DBMS of the _DEFAULT handler and then add all tables *configured* to be managed by other handlers

When fetching the tables, it skips tables whose names begin with BIN$, as this is taken as a table coming from the "Recycle Bin" on Oracle.

Returns:

boolean If true, it will check only if FIELDs are configured and ignore the mapped table name if any.
Returns:
mixed Returns an array of table names (parsed version of input table) if mapping is needed, otherwise just false.

ux_t3lib_DB::map_assocArray ( input,
tables,
rev = FALSE 
)

Takes an associated array with field => value pairs and remaps the field names if configured for this table in $this->mapping array. Be careful not to map a field name to another existing fields name (although you can use this to swap fieldnames of course...:-) Observe mapping problems with join-results (more than one table): Joined queries should always prefix the table name to avoid problems with this. Observe that alias fields are not mapped of course (should not be a problem though)

Parameters:
array Input array, associative keys
array Array of tables from the query. Normally just one table; many tables in case of a join. NOTICE: for multiple tables (with joins) there MIGHT occur trouble with fields of the same name in the two tables: This function traverses the mapping information for BOTH tables and applies mapping without checking from which table the field really came!
boolean If true, reverse direction. Default direction is to map an array going INTO the database (thus mapping TYPO3 fieldnames to PHYSICAL field names!)
Returns:
array Output array, with mapped associative keys.
