Helpful UDFs

Dear users,

Here are some UDFs that might me helpful in your business scenarios.

1. UDF to remove sequential leading values of string:


This UDF can be used in scenario where we get an input string from which we intend to pass only the required part of it, removing the leading characters which appear in a sequence. UDF consists of two input fields of which first one is input field (original string) and second one is the value which is to be deleted from the original string value.

               Code:


                        while(InputString.startsWith(Value))

                        InputString = InputString.substring(Value.length());

                        return InputString;

                 

               Examples:

              

             a.                 InputString                          Value                               Output

2. UDF to Add Leading Zeroes:


This UDF can be used in a scenario where the requirement is to add leading zeroes to a string to make the total length of the string to a fixed value (for example 10).

                             /wp-content/uploads/2016/08/4_1023075.png

                    Code:

                             int defaultLength = 10;

                             String valueZero = “0”;

                             int strlength = givenString.length();

                             int diff = defaultLength – strlength;

                             String S = “”;

                             for(int i = 0; i<diff; i++)

                             S = S + valueZero;

                             return S + givenString;

                                                                 Input                                    Output
