MySQL ALTER TABLE 语法错误修复 - 修改 image_type 字段类型

The correct syntax for the ALTER TABLE statement in MySQL is:\n\n\nALTER TABLE table_name MODIFY column_name column_definition;\n\n\nIn your case, the correct syntax would be:\n\n\nmysql> ALTER TABLE generate_images MODIFY image_type varchar(64) not null comment '图片下载类型:psd,ai,jpg,png,ppt,gif';\n
