Question

I have two tables and from that I am generating a query. I have columns in my query with field type yes/no. These are basically columns to determine the race of a person. The user enters information in yes/no for various races. I want another calculated column in the query which checks for all other race columns and calculates values in it.

I have to check for a few conditions in for the values in columns
For example:

1) If Hispanic is chosen, the new column should say hispanic(no matter what other options are selected. This is like a trump card)

2) If more than one is selected, then new column entry should say “multi”

3) If none of the options are selected, it should say “unknown”

4) If exactly one of them is selected, then that race should be displayed

Can anyone help me with this? I am new to Access

I can’t code it for you but I can point you in the right direction. What you want to do is take all the tests you explained above and put them in a coded format :

iif ( condition, value_if_true, value_if_false )

Since you have a lot of possible outputs i’d use something like a Case Statement where you can test for all the possibilities.

Follow this link if you need any info on how to code both type of statements (iif and case).

Once you have tried something like this, you can comeback with a specific question if you encountered a problem in the process.

Good luck with your database.
