mysql发布更新sql时修改表结构使用储存过程增加容错判断

1.使用 if not exists判断增加字段是否存在

IF NOT EXISTS(SELECT 1 FROM  information_schema.COLUMNS WHERE TABLE_SCHEMA=(SELECT database()) AND table_name='t_trans_surgery_info' AND COLUMN_NAME='dept_name') THEN
alter table t_trans_surgery_info 
        add column dept_name varchar(255) DEFAULT NULL COMMENT '科室名称';
end if;

贴上一个版本的更新sql
