You cannot explicitly skip rows at the end but you can allow a certain number of errors with the MAXERROR parameter. 您不能在末尾显式跳过行，但可以使用MAXERROR参数允许一定数量的错误。 Should be able to set that to ( number of lines to skip * number of files to be loaded ). 应该能够将其设置为（ number of lines to skip * number of files to be loaded ）。
