I don't want them automatically changed as not sure what table they are from so want the query to tell me what table they are from also
I don't want this to sound harsh, but I need to be honest with you. Some people confuse honesty with brutality, but I am just trying to be clear.
Access queries don't work the way you describe. I believe you have an incorrect understanding of queries. But worse than that, I suspect you have bad design issues if you have the same problem in multiple tables such that a hypothetical query would be able to tell you about the table in which this problem was discovered. If you have the same kind of data in several tables, your design is not normalized and that will make you work VERY much harder than you want or need to.
You said earlier you didn't want to use SQL, but that is exactly what Access uses. When you do a query-grid design, Access will convert that to SQL and run that because the Access data engine IS an SQL engine. All modern database engines use SQL. You can't escape it.
In design terms, if you aren't sure from which table you are taking data, you can't even BUILD a query since the FROM clause is going to require you to name a table. It is a requirement of the syntax.
It IS possible to make a query case-sensitive and you are correct that in such cases, an ORDER BY clause would cause all upper case letters to appear before all lower case letters. However, if you have mixed case situations, you might find an even more confusing sort order.
Whatever you are trying to do, you are going to have trouble because this design has been described inconsistently. Your inconsistent discussion betrays a lack of understanding of what you are really trying to do, and this lack will absolutely kill any chances of success.
