这句SQL错在哪里了？
INSERT   INTO   data.d1
SELECT   *   FROM
(
SELECT   *   FROM   data.d2
UNION   ALL
SELECT   *   FROM   data.d3
UNION   ALL
);

[解决办法]
INSERT INTO data.d1
SELECT * FROM
(
SELECT * FROM data.d2
UNION ALL
SELECT * FROM data.d3
UNION ALL
) t;

把*全部换成字段名就可以了
[解决办法]
INSERT INTO data.d1
SELECT * FROM
(
SELECT * FROM data.d2
UNION ALL
SELECT * FROM data.d3
);

[解决办法]
INSERT INTO data.d1
SELECT * FROM
(
SELECT * FROM data.d2
UNION ALL
SELECT * FROM data.d3
) t

或者

INSERT INTO data.d1
SELECT * FROM data.d2
UNION ALL
SELECT * FROM data.d3
