Function
| Arg | Description | Type |
|---|---|---|
| func | Lambda function to evaluate e.g. x=>1+1 where x will be the current scope. | Lambda (required) |
Evaluate a vql lambda function on the current scope.
This allows you to use a string as a VQL function - the string will be parsed at runtime as a VQL expression and then evaluated.
You can access previously defined variables or functions within the scope.
Note that when eval calls the function, the current scope will be passed as the first parameter to the lambda.
Example:
LET AddTwo(x) = x + 2
SELECT eval(func="x=>AddTwo(x=1)") AS Three FROM scope()
