I have a LINQ query:
VB
Dim Db = New MyDataContext
Dim Qry = From cust in Db.Customers
Select cust.ID, cust.Name

View 2 RepliesI download a file into access. One field contains one to many numbers always separated by a colon and a space: I have no control over the download. TheNumbers have a 1 to many relationship to a customer. Each number must then be verified against two separate reference files, and if the numbers match the description related to the number will be displayed.I'm just learning visual basic. I've made the changes manually (yuk-this took forever); I've tried various string/conversion commands; I've taken the data and placed it into excel and tried to manipulate it, without success.In this case is always numeric. In another field, similar problem, it's a combination of text and numbers.
Example: Cust# TheNumbers
99 1234; 12345678; 123123; etc...
88 87654321, 345654, 98989898. etc..
The numbers can vary in length and quantity. For each customer each number must be loaded into one field.
Example outcome:
Cust# TheNumber
99 1234
99 12345678
