SQL 带 where 条件的左连接查询
[英]SQL query with left join with where condition
问题描述
请帮我更正这个查询，我需要这个 senderId 的数据
select count(tg."transferGroupId"),
tg."transferGroupId",
tg."senderId",
tg."receiverId",
tg."createdAt",
u."firstName"
from kit.kit_transfers as tg
where tg."senderId"='30b81071-0167-4736-a162-103a2165be3d'
left join users as u on tg."receiverId"=u.id
group by tg."transferGroupId", tg."senderId",tg."receiverId",tg."createdAt",u."firstName"

SQL 左连接与 JOIN 条件中的过滤器与 WHERE 子句中的过滤器
