Life with SQL server

In the realm of data analysis and database management, the challenge often arises when comparing fields between two tables. This becomes particularly daunting when the tables comprise an extensive list of over 100 fields each, and to top it off, the field names don't match between the two tables. In such scenarios, manual comparisons could be time-consuming and prone to errors. To tackle this conundrum, I devised a solution that efficiently addresses the task at hand: a dynamically generated function that automates field comparisons based on a field mapping table. This approach not only minimizes the room for error but also enhances the overall efficiency of the comparison process. The Core Idea: Utilizing Field Mapping The foundation of this approach lies in the concept of field mapping. Essentially, a field mapping table acts as a bridge between the two tables, defining the correspondence between fields that might not have the same names. The field mapping table includes entries
