sql - How to join tables on incompatible columns? -


I have a link to the timecards third party data file in the accesscard and in the area where I have a problem, as "short" Listed - area of ​​text. There is an employee number in that area, which contains all the numerical data. When I link to the employee file to get employee names, I do not get a full match on all the records. I used the keyword "wise" to change the number but how do I use that number to link to the employee file? We are converting essential data into numerical values ​​in two tables and then using those tables, but it takes time and automatically eliminates the purpose of current data.

You can convert on the fly 

  from SELECT * A , B WHERE CLNG (AID) = CLNG (BID)   
 (I assume that the column  A  is already numeric.)  < P> You can also make conversions using the syntax, but the query designer will not be able to display this query, if the function is used in the  ON  section.
