Function to define the output data type(s), length/precision, and scale of the parameters sent to the main function.
Example
FunctionNameParameterTypes <- function() { parameters <- list(datatype = c("int", "varchar"), length = c("NA", "100"), scale = c("NA", "NA"), name = c("k", "algorithm")) return(parameters) }
Arguments
datatype |
The data type of the parameter. |
length |
(Optional) The dimension of the parameter. |
scale |
The proportional dimensions of the parameter. |
name |
The name of the parameter. |
Description
When creating the parametertypecallback
function, you define one row for each parameter being sent to the function. You must specify a parametertypecallback
function if your UDx uses parameters.
