比较MS Access SQL查询中的两个表

Question

I have two Excel tables (A and B) with names of staff. I want to compare these two tables in MS Access.

I have an Access query which compares a field like [Lastname, Firstname] and gave me as result for every member of Table A with no equivalent member in Table B . In my SQL query, Access made a simple string compare. For example:

SELECT User.A, User.B 
WHERE User.A Is Null

The problem is that the name with umlauten (ä,ü,ö,ß) are not written synchron in both tables. Sometimes I have ä or ae, ü or ue etc. Can I use regex in Access SQL to solve this problem?

Thanks for helping.

Answer 1

The approach I would take is to translate the names into a standardized format, in a derived column in both table A and B. Then you can use this column for a simple string comparison.

The translation can be accomplished using the replace function in Access.
