 * Holds name of a table including schema and alias.
 * Usage is the following:
 *
 * (new Query)->select('col1')->from(new TableName('table1', 't', 'dbo'))
 *
 * Note: We use prefix from connection with tables which schema equals default schema or which has no schema.
 * Note: With `ExpressionInterface` as tablename we cannot add prefixes and quote table names.
 * For example, with Oracle: `(new Query)->select('*')->from(new Expression('dblink1.dbo.table'))` to build `select * from dblink1.dbo.table1`
