When Vantage evaluates a UDF expression, it invokes the function with the arguments passed to it. The following rules apply to the arguments in the function call:
- 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.
