MS Access-将字段值链接到列

Question

I have two tables in Access i am trying to relate: Products & Prices.

Following is a simplified example

ProductCode    ProductName
  A              Sugar
  B              Salt
  C              Bread


Date           A         B         C
01/02/2016     $1       $2        $3

I do not want to split the prices table as follows:

Date           Code    Price  
01/02/2016     A       $1    
01/02/2016     B       $2
01/02/2016     C       $3

Excuse my ignorance, as i am new to Access.

Thanks for the advice.

Answer 1

Probably not the answer you expect, but here it is anyway:
Access is a relational database , and when using it you are supposed to follow some design rules for your tables. Search the web for "database normalisation" (eventually normali z ation).

For instance, your Prices table is not properly designed: should you ever have a 4th product, it would require modification of the table structure. A better design would be something like:

PriceId as AutoNumber
dtReplaced as date  'leave Null for 'active' prices
ProductCode as string
Price as Currency

with a PK on PriceId and Unique Index on ProductCode + dtReplaced to avoid having 2 active prices for the same product.

Also note that Date is a reserved word, and should not be used as a field name, unless your are really looking for trouble.
