I need help in finding out why I am not getting any data in my query.
When I select all the fields in one table in my query grid and run it, the data is there. However, when I try to do it using to related tables and pull fields from both table in my query rid and run the query, data from both related tables are not showing in my query datasheet. What is the problem? The relationship line in my query is showing that the table are linked.
Thanks for your response in advance.

The relationship line means you are doing an inner join on the linked field, so only records that are equal in those fields from both tables will be shown.

Thanks for responding.
P.S. I have enough data in the fields and some are null fields. When I run the query and adding my criterias, the data should still show in my query datasheet. It is not doing it.

Did you run the query first without the criteria to verify that you have some records to apply the criteria to?

Yes, I did one table at a time. The results showed.
But when I combined both tables in my query grid and selected the fields I wanted from both tables to be in my datasheet, none of the data shows in my datasheet from both tables after I ran the query. However, the relationship is established.

Did you run the query with both tables and no criteria? I've had this happen when I expected NULL to match up with "" (empty string), and it didn't. I changed all the NULLs to blanks and then the join produced the results I expected. Double check to make sure the line between your tables in the query is between the two fields that have equal values in them.

Yes, I ran the table with a criteria in it. It still didn't give me not results (empty data). I will probably need to check to see if the relationship line between both of my fields have equal values. I'll let you know. Thanks

I checked my related fields in my table. The primary table have both Letter and numbers in the field and the Foreign table have regular letters (it is a combox box field in which I can select the values from the list). However, both of them have the same data types.

Your query is only going to have results when the values in the two related fields are exactly equal. It sounds like your two fields are not actually related at all.

Here is an example.
Primary Key Field (CustomerNumber ) value is "AC001"
Foreign Key Field (CustomerNumber ) value is "All Creatures". This is a lookup field that have the value list box.
I'm trying to rebuild this database from my Access 2000 Bible reference/text book called "Mountain Hospital Animal Database" and that's what the relationship is showing for these two tables. Both of these fields have the Text datatype.

the query field blank and the table field blank!

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
