方法详细资料

getTable

public Table getTable()

Retrieve the information regarding the Table this Column does belong to, if any can be inferred.

The inference is based only on local information, and not on the whole SQL command. For example, consider the following query:

  SELECT x FROM Foo
 

Given the Column called x, this method would return null, and not the info about the table Foo. On the other hand, consider:

  SELECT t.x FROM Foo t
 

Here, we will get a Table object for a table called t. But because the inference is local, such object will not know that t is just an alias for Foo.

返回:

an instance of Table representing the table this column does belong to, if it can be inferred. Can be null.
