Drop down list to select desired codes of a category

[Islamzada]

Dear Friends;
I have a problem in drop down list, well I have two tables which i want to prepare a store database.

I have two tables;

in table code below are introduced:
Consumption Group: Con-001
Con-002
Fixed groups : Fix-001
Fix-002
Raw materials : RAW-001
: RAW-002

in table M_Code below are introduced:
Categories: "Consumption" or "Fixed" or "Raw Material"
Code:Con-001 or fix-001
Name: book, note book or whatever
Description:

Note, I have introduced many codes for fixed, consumption and raw materials nearly 1000 code for each group.

Now what i want to do is, that in M_code table when I select any of three category the related codes which are belongs to that category appear.

Please help me.

There are a few ways of doing this. Probably the easiest (and the most normalized) would be to have a third table that just has your different types of codes, Consumption, Fixed, and Raw. The table design would be something like

Name: tblCodeType
Fields:
TypeID, Primary Key, AutoNumber
Type, Text

Your data would then be

1     Comsuption
2     Fixed
3     Raw Material

You would then add a field to your table of codes so that each code could be categorized so that we could know which type of code it is. This will allow us to display only to codes which are of the type selected.

Now, what do you mean by appear? Do you want them in a subform, a combo box, or do you want a new form to open? Exactly how do you want them to appear?

Your database sounds like you're well on your way; however, I get the feeling from your post that you're still either unsure of your design, or that this may be one of the first database projects you've undertaken by yourself.

Therefore, before you get too much farther into the current development you really should take a look at the following: A Tutorial for Access as the these basics will be vital to saving you many tears and hours of "banging into the wall."

Database Normalization and Table Structures. is one of the hardest concepts for people to grasp when it comes to database design. We're so used to spreadsheets with flat-data that this just doesn't seem to make sense. Until you need to manipulate the data.
