# groupBitXor {#groupbitxor}
|
||
|
||
对于数字序列按位应用 `XOR` 。
|
||
|
||
**语法**
|
||
|
||
``` sql
|
||
groupBitXor(expr)
|
||
```
|
||
|
||
**参数**
|
||
|
||
`expr` – 结果为 `UInt*` 类型的表达式。
|
||
|
||
**返回值**
|
||
|
||
`UInt*` 类型的值。
|
||
|
||
**示例**
|
||
|
||
测试数据:
|
||
|
||
``` text
|
||
binary decimal
|
||
00101100 = 44
|
||
00011100 = 28
|
||
00001101 = 13
|
||
01010101 = 85
|
||
```
|
||
|
||
查询:
|
||
|
||
``` sql
|
||
SELECT groupBitXor(num) FROM t
|
||
```
|
||
|
||
`num` 是包含测试数据的列。
|
||
|
||
结果:
|
||
|
||
``` text
|
||
binary decimal
|
||
01101000 = 104
|
||
```
