  • 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:
