For every expert, there is an equal and opposite expert. Shouldn't this be in an Access forum? Anyway, I rather not spend time to write the actual query for this. However, I can give you an idea of how to address it. To make it simpler, filter for a Status of Active. This should be more than enough to get you started.
If you need additional help, search for "SQL Server, find duplicate rows". Then click on the Save button at the top left of the window this is the button with the picture of the disk.

The expression could be that records should only be about students who live in a single parent home. The same types of expressions are used in SQL, following some rules.

To build your expressions, you can use any of the Boolean, logical, and comparison operators we have studied. Practical Learning: Querying by Selection.
While Microsoft Access is faithful to the SQL, it adds its own little details when creating or interpreting the statements it is confronted with. Instead of using field names as we have done so far, Microsoft Access likes recognizing the object that holds a field just by looking at the referred field. When studying operators, we saw that the name of a field should be delimited by square brackets to reduce confusion in case the name is made of more than one word.
We also mentioned that the square brackets provide a safeguard even if the name is in one word. Based on this, to create a statement for a query that includes the first and last names of a Persons table, you can write it as follows:. To identify a field as belonging to a specific table or query, Microsoft Access usually associates its name to the parent object.
This association is referred to as qualification. To qualify a field, you consider the object that is holding the field, then add a period followed by the name of the field. Imagine you want to get a list of Persons by their last names from data stored in the Persons table. Using this syntax, you can use a statement as follows:. In the same way, if you want to include many fields from the same table, qualify each and separate them with a comma. Was this information helpful?
