qlite 产生错误
原标题:sql error creating trigger in sqlite

I am using sqlite 2.8.17 installed on ubuntu lucid ( I used apt-get install sqlite)

我有一个<代码>college的表格,我试图制作一个触发器(如dbclass.org录像中所提及的)

create trigger R4
before insert on College
for each row
when exists (select * from College where cName = New.cName)
begin
  select raise(ignore);
end;

造成错误

SQL error: near "select": syntax error

专栏

create table College(cName text, state text, enrollment int);
