Access Tip: More With Text Strings
By Richard Rost   Richard Rost on Facebook Richard Rost on Twitter Richard Rost on Google Plus Richard Rost on LinkedIn Email Richard Rost

 
I added a new video to an existing question in the TIPS section. One of the most popular topics that I get asked about is how to manipulate data in text fields. Here's another example to take a look at:

More With Text Manipulation

It deals with Left, Right, InStr, and Trim some more.

Further Question Comment from Angel @ 7/30/2009
I understanding about setting up the tables and I set up the relationships.  I built a StockT Table with the following fields:

ID(Automumber)
FirstName
LastName
StockName
Quanity
StockPrice

Just for clarification, what I need to do is change the StockPrice on one particular kind of stock if possible with one function.  Because there could be 50 customers with the same stock.  I know that there is a find and replace function, but that won't work when the price and the stock name are two separate fields (columns). So are you saying that the two separate fields(which are 2 columns) can be bound together by a third column?
Sorry, but with my inexperience I just need to clarify this.

Thank you much!

Question on Ordering More CD. Comment from Richard Rost @ 7/29/2009
Angel, first make sure you understand setting up proper tables and relationships, which I cover in Access 201 and 202. Then, you need to understand a three-way relationship with something called a JUNCTION table (or cross-reference table). This is how you can have two separate lists of things bound together by a third column. This is a little more advanced, and I cover it in Access 309.

For example, you would have a CustomerT table, with information like CustomerID, name, address, phone, etc. You would have a StockT table with your StockID, current price, volume, etc.

Now, you'd set up a junction table that has CustomerID, StockID, and any other information about the transaction between the other:

ID (Autonumber)
CustomerID
StockID
PurchaseDate
Notes

See Access 309 for details.

Question on Ordering More CD. Comment from Angel @ 7/27/2009
Richard,
First of all thank you very much for your instructions a few weeks ago.  I am going to order Access 102, but before I do, I need to order an additional CD that has instructions regarding being able to change data that is the same in more than one place.  Let me give you an example. Remember I said that I have 100 clients that own about 20 plus or minus stocks each.  Some of these stocks are repeated in several clients accounts.  The stock names wouldn't change, but I will have to periodically change the price of the stock.  Is there a way or a CD that explains how to universally change the price of the "same" stock in everyone's account at the same time?
Can this even be accomplished in Access.  

Thank you
Angel
