增加字段提示以下信息，如何解決,？
Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs
alter table ***_ecms_infoclass_info add zz_jdtype text not null,add z_jdtype varchar(255) not null,add qz_jdtype varchar(255) not null,add save_jdtype varchar(10) not null;
超過mysql允許的最大單表長度，解決辦法是：減少字段,，或字段少用text類型
