我对这个也不熟，如果你的表么有什么constraint的话
如下代码应该能达到

SQL code

declare @cmd varchar(4000)declare cmds4 cursor for Select    'drop table [' + Table_Name + ']'From    INFORMATION_SCHEMA.TABLESWhere    Table_Name like 'tblacad%'open cmds4while 1=1begin    fetch cmds4 into @cmd    if @@fetch_status != 0 break    exec(@cmd)endCLOSE cmds4DEALLOCATE cmds4

[解决办法]
提供思路如下

先用语句取出所有系统表的名称，可以根据李过滤

循环所有出来的表名，逐个drop table
