SELECT thinkphp., rownum AS numrow FROM (SELECT "U"."","F"."id" FROM "user" "U" LEFT JOIN "usergroup" "F" ON "F"."uid"="U"."id" WHERE "U"."id" = 1) thinkphp

单独的
SELECT "U"."","F"."id" FROM "user" "U" LEFT JOIN "usergroup" "F" ON "F"."uid"="U"."id" WHERE "U"."id" = 1
正常显示，如果加上SELECT thinkphp., rownum AS numrow FROM (SELECT "U"."*","F"."id" FROM "user" "U" LEFT JOIN "usergroup" "F" ON "F"."uid"="U"."id" WHERE "U"."id" = 1) thinkphp
就报错，General error: -2112 第1 行附近出现错误: 有歧义的列名[id]

这个语句应该怎么写，如果不想去掉*的话。
