postgresql中基础sql查询,postgresql,postgresql,sql,java

SQL使用SELECT和FROM查询表中的数据，
*表示查询全部字段；
PostgreSQL提供了无表查询的扩展，使用AS指定别名；
使用DISTINCT去除查询结果中的重复值；
PostgreSQL支持两种格式的代码注释。

利用查询条件过滤数据

PostgreSQL使用WHERE子句过滤表中的数据；
PostgreSQL提供了以下比较运算符：=、！=、 BETWEEN、IN等。

模糊查询

 -- sh sa
  -- %任意多个字符
  -- _任意一个字符
  select first_name
  from employees
  where first_name like 'S_%';

create table t_like (v TeXT);

insert into t_like(v) values ('进度 25%已完成');
insert into t_like(v) values ('日期：2022年6月25日。');

select * from t_like;

-- 查询包含25%的字符串
-- escape转义#后的字符
select * from t_like where v like '%25#%%' escape '#';
-- 也可以使用\进行转义，效果和escape一样
select * from t_like where v like '%25\%%';
