difference between VARCHAR NVARCHAR in SQLite

In Microsoft SQL Server, VARCHAR is ASCII and NVARCHAR is Unicode (UTF-16). In SQLite, all text is Unicode, so it's not relevant. In any case, SQLite is loosely typed so it wouldn't make a difference anyways. Seehttp://www.sqlite.org/datatype3.html:)

在SQL Server中，VARCHAR是ASCII编码而NVARCHAR是Unicode编码（UTF-16）. 在SQLite中，所有的文本都是Unicode，所以VARCHAR和NVARCHAR没什么区别。SQLite的类型是松散的，所以不会有很大的不同，详见http://www.sqlite.org/datatype3.html
