declare @outter intdeclare @inner intdeclare @tablePrefix varchar(30)declare @tableName varchar(36)set @outter=1set @inner=0while (@outter<=12)begin set @tablePrefix='BankPayOrder_'+convert(varchar,@outter)+'_' while(@inner<=9) begin  set @tableName=@tablePrefix+convert(varchar,@inner) execute('delete from '+@tableName+'') set @inner=@inner+1 end set @inner=0 set @outter=@outter+1end
