postgreSQL使用delete删除数据的时候关联多个表

看个例子就知道了

删除game_pg_getpoint表中的数据，需要关联getpoint表

DELETE FROM game_pg_getpoint USING getpoint  
	WHERE (getpoint.fixflg = 1 OR game_pg_getpoint.immediately_flag=1) 
	AND game_pg_getpoint.memberid = getpoint.memberid 
	AND game_pg_getpoint.comment = getpoint.comment 
	AND game_pg_getpoint.thanksid = getpoint.thanksid 
	AND game_pg_getpoint.thanksname = getpoint.thanksname 
	AND game_pg_getpoint.getpoint_regist_date = getpoint.registdate
