推荐答案
Hello Akash,
Hello Akash,
extend 运算符可用于创建计算列并将它们附加到结果集。例如:
The extend operator can be used to create calculated columns and append them to the result set. For example:
T | extend duration = endTime - startTime
AFAIK,虽然给出ColumnName是可选的,但它不能是空格。有关扩展

AFAIK, although giving the ColumnName is optional, it cannot be a blank space. More about extend here.
为了重命名,你有没有检查过项目重命名运算符?它的工作方式如下:
For renaming purposes, have you checked out the project-rename operator yet? The way it works is as follows:
T | project-rename new_column_name = column_name
