mysql - MySql中的跨表更新查询

Question

我可以在 SQL Server 中执行这种查询:

update tblmembers 
set hits_archived = 
  (select count(*) 
   from tblhits 
   where tblhits.target_id=tblmembers.id 
   and tblhits.hitdate < '2009-11-01') 
where tblmembers.regdate < '2007-09-28'

如何在 MySql 4.0.23 中执行此操作？我尝试执行查询，但它返回了此错误消息:

You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'select count(*) from tblhits where tblhits.target_id=tblmem

Answer 1

这也可以通过使用 MySQL 的子查询来完成。

Subquery Syntax
