我有一个表,其中包含多个列,其中包含存储为 Ascii 字符串的信息。似乎没有内置函数可以做到这一点。这是我的示例输入:
let T=datatable(Hex1:string, Hex2:string) ["74 65 73 74 31", "74 65 73 74 32", "74 65 73 74 33", "74 65 73 74 34 “
我可以通过将每列重命名为“Hex”来将其与以下函数的输出连接起来,然后将列重命名回 Hex1、Hex2 等,从而做出一个丑陋的解决方法,但这看起来非常笨拙。理想情况下,我正在寻找一个标量函数,它接受像“74 65 73 74 31”这样的字符串并返回其 Ascii 等效项“test1”
.create-or-alter function with (folder="Test") ['StringHexToAscii'](T:(Hex:string)) {
let Converter = datatable (Hex:string, Ascii: string) [

| extend HexArray = split(Hex, " ")
| mv-expand HexArray
| extend HexArray=tostring(HexArray)
| lookup Converter on $right.Hex == $left.HexArray
| summarize Ascii=make_list(Ascii) by tostring(Hex)
| project Hex, Ascii=strcat_array(Ascii, "")
}
最佳答案
您可以尝试以下替代方案:
split()
将字符串分解为单独的十六进制值mv-apply
、tolong()
)动态
数组(使用summarize make_list()
动态
数组上调用make_string()
datatable(Hex1:string)
[
"74 65 73 74 31",
"74 65 73 74 32",
"74 65 73 74 33",
"74 65 73 74 34",
]
| mv-apply num_as_string = split(Hex1, " ") on (
summarize nums = make_list(tolong(strcat("0x", num_as_string)))
)
| project Hex1, Str1 = make_string(nums)
-->
| Hex1 | Str1 |
