I need to compare data in two tables. Table 1 has the full, 9-digit social security number, but Table 2 only has the last four digits. I know I could extract the last four digits of the first table in Excel using Text to Columns, but it seems like there would be a way to do this when I create the subset of data for Table 1. I'm not real fluent in SQL, but understand the principles. This will be used on a monthly basis verify vendor statements, so I'd like to automate as much as possible now.
Appreciate an answer to this one.
