第一步:创建序列


create sequence TBL_SIGNAL_TG_INSERTID
increment by 1
start with 1

序列名称:TBL_SIGNAL_TG_INSERTID

第二部,设置触发器:


CREATE
OR REPLACE TRIGGER " HONG "." TBL_SIGNAL_TG_INSERT " before INSERT ON TBL_SIGNAL FOR each row begin select TBL_SIGNAL_TG_INSERTID .nextval into :new.ID FROM dual;
end;

HONG:表空间

TBL_SIGNAL_TG_INSERT:触发器名称

TBL_SIGNAL :表名

TBL_SIGNAL_TG_INSERTID : 序列

代码运行异常: 本文照着编译,直接编译失败,提示如下: arm-linux-androideabi-gcc is unable to create an executable file. C compiler test failed. If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.
