從表中插入數據

Question

我有一張表，我需要更新基本上是重複的數據，除了一列數據。

我的表名是tblSupporters

我列

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

我需要將數據從我的表複製其中SYear等於2012，並插入到相同的表，但改變SYear至2013年

我知道這很簡單，但我對此很陌生。

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; 

我的猜測是，id自動分配，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;
