Sql 将同一表中的数据插入表中

我有一个需要更新的表，除了一列数据外，它基本上是重复的数据

我的表名是tblSupporters

我的专栏是

ID, SYear, Type, Support Location, City, State, Info.

我需要从SYear等于2012的表中复制数据，并插入到同一个表中，但将SYear更改为2013

我知道这很简单，但我对这很陌生

只需使用插入。选择：

我猜id是自动分配的，因此您可能真的想要：

insert into tblSupporters(SYear, Type, Support Location, City, State, Info)
    select 2013 as SYear, Type, Support Location, City, State, Info
    from tblSupporters
    where SYear = 2012;

insert into tblSupporters(SYear, Type, Support Location, City, State, Info)
    select 2013 as SYear, Type, Support Location, City, State, Info
    from tblSupporters
    where SYear = 2012;
