生成存储过程代码

下面是自动产生存储过程的sql 脚本,你可以在查询分析器中运行.

运行完,你会看到多了四个存储过程

pr__SYS_MakeInsertRecordProc

pr__SYS_MakeUpdateRecordProc

pr__SYS_MakeSelectRecordProc

pr__SYS_MakeDeleteRecordProc

执行方式：在查询分析器中执行

pr__SYS_MakeInsertRecordProc ‘表名‘         --得到插入语句

pr__SYS_MakeInsertRecordProc ‘表名‘,1  　 --得到插入语句，并创建Insert存储过程

 

完整脚本如下:
