其实一开始没增加begin...exception...end时,PostgreSQL报错“can't begin/end transaction in pl/pgsql”,已经隐含了这层信息。只是脑子里还是延续Oracle的习惯,而画蛇添足了。 于是,修改存储过程的脚本,按最简单的法子来: createorreplacefunctionp2(pidint, pnamevarchar)returnsvoidas$$begininsertintot1values...
In both cases, ROLLBACK TRANSACTION decrements the @@TRANCOUNT system function to 0.
