Describe the problem

CREATE TABLE t1 (sku int PRIMARY KEY, pr int)engine=stonedb;
CREATE TABLE t2 (sku int PRIMARY KEY, sppr int, name varchar(255))engine=stonedb;

INSERT INTO t1 VALUES
  (10, 10), (20, 10), (30, 20), (40, 30), (50, 10), (60, 10);

INSERT INTO t2 VALUES 
  (10, 10, 'aaa'), (20, 10, 'bbb'), (30, 10, 'ccc'), (40, 20, 'ddd'),
  (50, 10, 'eee'), (60, 20, 'fff'), (70, 20, 'ggg'), (80, 30, 'hhh');

SELECT t2.sku, t2.sppr, t2.name, t1.sku, t1.pr
  FROM t2, t1 WHERE t2.sku=20 AND (t2.sku=t1.sku OR t2.sppr=t1.sku);

##The error results are as follows
+-----+------+------+-----+------+
| sku | sppr | name | sku | pr   |
+-----+------+------+-----+------+

CREATE TABLE t2 (sku int PRIMARY KEY, sppr int, name varchar(255))engine=stonedb;

INSERT INTO t1 VALUES
  (10, 10), (20, 10), (30, 20), (40, 30), (50, 10), (60, 10);

SELECT t2.sku, t2.sppr, t2.name, t1.sku, t1.pr
  FROM t2, t1 WHERE t2.sku=20 AND (t2.sku=t1.sku OR t2.sppr=t1.sku);
