Mysql 将多个结果合并为1

假设我有多个查询：

SELECT col1, col2 FROM tab1;
SELECT colA, colB FROM tab2;
SELECT colTest, colBlah FROM tab3;

每个查询只返回一个结果

如何将这3个结果合并为1个

结果如下所示：

+------+------+------+------+---------+---------+
| col1 | col2 | colA | colB | colTest | colBlah |
+------+------+------+------+---------+---------+
| abc  | def  | Ghi  | JkL  | 12A     | 42BD    |
+------+------+------+------+---------+---------+

加入他们：

SELECT t1.col1, t1.col2, t2.colA, t2.colB, t3.colTest, t3.colBlah
FROM tab1 AS t1
CROSS JOIN tab2 AS t2
CROSS JOIN tab3 AS t3

@user1170330-（我知道您说过这些语句只返回一条记录，但是…）当涉及多条记录时，请确保您理解。

select tab1.col1, tab1.col2, tab2.colA, tab2.colB, tab3.colTest, tab3.colBlah from tab1, tab2, tab3
