hey guys i'm just curious. in the relationships table i can add both tables and queries to the canvass.

1) can i create a relationship from a query to a table or i can't, it's just there for me to visually see the select query?

(i tried creating a relationship from the select query to the table but the below is what it shows me)

2) i've heard about views. is a select query a view? so all my select queries in access are views right? if they're not, what's the difference between a view and a select query? thanks!

Yes,  you can create a relationship between a query and a table (in the query designer or SQL view).  When you try to create the relationship and double click on the line joining the two tables, it will display the table/query names at the top and the fields that are currently linked in the section above the check boxes.

A "view" is the term that SQL Server uses for saved queries, it is not usually a term associated with Access queries.

The difference is that when using a query, the relationsship is just informal and for display only - that why the three textboxes are greyed out.

When you are building table relationships, it is generally to ensure some form of referential integrity (ie, you must have a matching record in one table for an entry in another table).  An example of this would be a States table and an Address table.  With a properly defined relationship, you would not be able to enter ZZ as a [StateCD] field in tblAddresses if there is not a matching [StatesCD] value in tblStates.

However, when a relationship is defined in a query, it is normally so that you can retrieve other information from a second table, based on the value in the first table.

"Yes,  you can create a relationship between a query and a table"

You are not creating a Relationship in this scenario.  You are merely defining how you want the AutoJoin feature of the Access UI will JOIN when using both the Query object and Table object in another Query object.

Remember, a Relationship (with R/I, of course) is a constraint that governs data going into the database must adhere to.  A JOIN is how the data is presented to the user.  A "Relationship" without R/I is, again, a simply a suggested JOIN for the AutoJoin feature.

datAdrenaline,

Your are, of course, correct about the difference between a "relationship" and "join".  I stand corrected, and should have used the word JOIN in both my earlier posts when referring to queries.
