如何在classpath（h2数据库）中使我的触发器可用

Question

当我调用查询时：

st.execute("create trigger myTrigger after insert on NEWPOPULATION for each row call "\NewPopulationTrigger\" ");

控制台写：Class NewPopulationTrigger not found

我该如何遵循句子"The trigger class must be available in the classpath of the database engine" - 我该如何实施呢？

Answer 1

包必须在班级名称的左侧给出。

在H2示例中。包是org.h2.samples，类是TriggerSample

CREATE TRIGGER INV_INS AFTER INSERT ON INVOICE
FOR EACH ROW CALL "org.h2.samples.TriggerSample"

在你的情况下，干净的方法是在java中询问全名：

st.execute("create trigger myTrigger after insert on NEWPOPULATION for each row call \""+NewPopulationTrigger.class.getName()+"\"");
