using queries for the first time, need some help
I''ve been through a few different online training courses and I'm still not
able to make queries. I have 4 tables that inventory our woodshop tools. Within each table is a column with a drop-down box list of categories that is listed in another table- machinery, manual tools, power tools, etc. As an example, I wanted to make a query that groups together all the tools in the "manual tool" section of the category drop down. How do I do this? Thank you! |

I don't think I understand what your trying to do here.
Some more table information, and sample data in each table would be useful. But... I would initially suspect a table design problem. Why isn't all your shop's equipment in one table, like... ToolID Category Description SerNo... etc.... 142 Manual Awl None 612 Manual Screwdriver None 701 Machine Drill Press A15243 39 Power Hand Grinder K41-J12 432 Machine Lathe XF-342-3 Then it would be a simple matter to filter the query with a criteria against Category like = "Manual" -- hth Al Campagna Candia Computer Consulting - Candia NH http://home.comcast.net/~cccsolutions "toolinventory" wrote in message ...

Al
the table you drew up is actually very close to what I am doing, but I have four different ones. and where it says "category" on yours, there would be a drop down box. I only did 4 different tables because I need to divide up the tools into different employee's workbenches and other stuff-- i.e., a table titled "Jim's Workbench", one titled "Mike's Workbench", "Office and Computer", "Main tool list", etc (there's actually like 7, not 4. If it would make it easier, I could put it all into one big table, but then I don't know how to keep stuff seperate. But what I was initially trying to do is make a query that answers the question, "how many manual tools does the entire shop (within all the employee's workbenches) have"?

From what you've indicated so far... all these items should be in one table.
Breaking it up into 7 tables is not using the "relational" power of your database. (hope the email format doesn't scramble/misalign the text too much) tblToolInventory... ToolID Category Desc SerNo... OwnerID ------------------------------------------------------------------- 142 Manual Awl None 23 612 Manual Saw None 15 701 Machine Lathe1 A152 12 39 Power Grinder K41-J1 23 432 Machine Lathe2 XF-342 19 From this data, queries can be created that show any possible combination of tool vs location vs category vs etc.. etc.. just by simple filtering criteria and/or conditions. AND... adding another table... tblOwners OwnerID Owner LocationID ---------------------------- 23 Bob Workbench1 15 Jim WorkBench3 31 Mary Off & Comp1 etc... etc... On form ToolInventory... You select a OwnerID from a combobox (fed by tblOwners) on your ToolInventory form. Using the relational power of the database, the system knows (via tblOwners) that the Owner = Bob at Location = WorkBench1. Why do it this way? If Bob should quit, replace the OwnerID name in tblOwners to the new employee's name (say Henry), and all Bob's tools are reassigned to Henry instantly. Maybe Bob (WB1) and Jim (WB3) switch places... just switch the their Locations in tblOwners... and your done! Now this example may not be "exactly" what you want, and there may be other issues to consider, but it does show the use of the power of a relational database. -- hth Al Campagna Candia Computer Consulting - Candia NH http://home.comcast.net/~cccsolutions "toolinventory" wrote in message ...
