从表中插入数据

Question

我有一张表，我需要更新基本上是重复的数据，除了一列数据。

我的表名是tblSupporters

我列

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

我需要将数据从我的表复制其中SYear等于2012，并插入到相同的表，但改变SYear至2013年

我知道这很简单，但我对此很陌生。

Answer 1

只需使用insert . . . select：

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

我的猜测是，id自动分配，所以你可能真的想：

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;
