When evaluating a UDF expression, Vantage invokes the UDF with its input arguments. The following rules apply to the input arguments:
- The arguments must be comma-separated expressions in the same order as the parameters declared in the function.
- The number of arguments passed to the UDF must be the same as the number of parameters declared in the function.
- The data types of the arguments must be compatible with the corresponding parameter declarations in the function and follow the precedence rules that apply to compatible types.
