如果SQL SERVER表中存在两条一模一样的记录,修改其中任何一条时就会报错
在SQL Server Enterprise Manager中错误提示为:
Key column information is insufficient or incorrect.Toomany rows were affected by update.
在delph中用edit,post提交时提示:
Project eims_system.exe raised exception class EOLeException with message 'Key column informmation is insufficient or incorrect.Too many rows were affected by update.'Process stopped.Use Step or Run to continue.
我在表定义时没设置Primary Key哦
怎么会有这样
