## 工作记录------常用SQL ##

### 给表新增字段以及注释 ###

ALTER TABLE 表名 ADD 字段名 字段类型 DEFAULT NULL comment ‘注释’;

> ALTER TABLE t\_user ADD user\_id VARCHAR(64) DEFAULT NULL comment ‘userId（关联字典表）’;

### 给表字段以及注释，修改表字段 ###

> alter table t\_user user\_id VARCHAR(32) NULL DEFAULT NULL COMMENT ‘用户id’ COLLATE ‘utf8\_general\_ci’;

### 导出表结构 ###

> SELECT  
> COLUMN\_NAME 列名,  
> COLUMN\_TYPE 数据类型,  
> DATA\_TYPE 字段类型,  
> CHARACTER\_MAXIMUM\_LENGTH 长度,  
> IS\_NULLABLE 是否为空,  
> COLUMN\_DEFAULT 默认值,  
> COLUMN\_COMMENT 备注,  
> table\_name 表名  
> FROM  
> INFORMATION\_SCHEMA.COLUMNS  
> WHERE  
> – 填写要导出表结构的数据库名称即可  
> table\_schema = ‘test’  
> – order by table\_name  
> – 如果不写的话，默认查询所有表中的数据  
> AND table\_name = ‘table\_1’;
