MySQL-仅选择列具有唯一值的行

Question

我找到的与我所寻找的最接近的东西是，所以我将以它为例

MySQL：选择除列之外仅具有唯一值的行

给定这个数据集

+----+--------------+-------------+------+------+-------+-----+
| ID | SATELLITE_ID | ATT_TYPE_ID | TIME | ROLL | PITCH | YAW |
+----+--------------+-------------+------+------+-------+-----+
|  1 |            1 |           1 | 2012 |  1.0 |   2.0 | 1.3 |
+----+--------------+-------------+------+------+-------+-----+
|  2 |            1 |           1 | 2012 |  1.0 |   2.0 | 1.3 |
+----+--------------+-------------+------+------+-------+-----+
|  3 |            1 |           1 | 2011 |  1.0 |   2.0 | 1.3 |
+----+--------------+-------------+------+------+-------+-----+

我只想返回

+----+--------------+-------------+------+------+-------+-----+
| ID | SATELLITE_ID | ATT_TYPE_ID | TIME | ROLL | PITCH | YAW |
+----+--------------+-------------+------+------+-------+-----+
|  3 |            1 |           1 | 2011 |  1.0 |   2.0 | 1.3 |
+----+--------------+-------------+------+------+-------+-----+

因为它是唯一的唯一行

mysql有可能吗？

Answer 1

SELECT 
    ID, 
    SATTELLITE_ID, 
    ATT_TYPE_ID, 
    TIME, 
    ROLL, 
    PITCH, 
    YAW 
FROM Table 
GROUP BY 
    SATTELLITE_ID, 
    ATT_TYPE_ID, 
    TIME, 
    ROLL, 
    PITCH, 
    YAW 
HAVING COUNT(*) = 1

Answer 2

group by having count(*) = 1使用group by

Answer 3

尝试这个：

SELECT * FROM temptbl 
GROUP BY satellite_id, att_type_id, time, roll, pitch, yaw 
HAVING COUNT(*) = 1;
