有条款面临的问题

Question

select *
from db_user
order by date_created asc OFFSET 1 ROWS FETCH NEXT 10 ROWS ONLY
having full_name like 'Admin%';

获取错误：

[S0001][156] Incorrect syntax near the keyword 'having'.

如何解决这个问题，因为 'where' 子句也给出错误。

Answer 1

having 用于过滤掉来自 group by 子句的分组结果。如果您只想过滤掉行，您应该使用 where 子句。请注意，它应该出现在之前 order by 子句：

SELECT   *
FROM     db_user
WHERE    full_name LIKE'Admin%' -- Here!
ORDER BY date_created ASC OFFSET 1 ROWS FETCH NEXT 10 ROWS ONLY

Answer 2

HAVING 用于带有 groupby 语句的查询，以根据 聚合列 的值过滤结果。您应该改用 WHERE。

正确的查询是：

select *
from db_user
where full_name like 'Admin%'
order by date_created asc OFFSET 1 ROWS FETCH NEXT 10 ROWS ONLY
;
