What would be the best approach (workflow, jscript, calculation, CSS, etc.) to extract the first three characters from the Last Name field, the first character from First Name field and the last 4 digits from the SSN field in forms and populate the result (in all caps) in the Employee ID field in SQL table? Can you provide the details of the best method based on the following forms field data:
First Name: John
Last Name: Smith
Social Security Number: XXX-XX-1234
Desired SQL Table Column Result for Employee ID: SMIJ1234
