/**
* Various column alias types. Sometimes, when database JDBC driver does not
* support table names in ResultSet metadata, it might be useful to include
* table name or a reference in the column name, separated by some separator.
*
* Using TABLE_NAME type might be dangerous, since most databases (including Oracle)
* has some maximum length for column names, so adding table name prefix might
* be too much;)
*
* Column types are usually used internally by SQL generators (see: {@link DbSqlGenerator}).
