Updating linked database c

If there is enough interest, I could use that as the topic for a future article, but first and foremost is the need to understand how to update the table links themselves.

Although this process works are you familiar with any other options to directly perform the INSERT, UPDATE or DELETE operations?This has been beneficial for us because in our environment because our business users provide data to us in the form of Excel spreadsheets.Many of the situations end up translating to INSERT, UPDATE or DELETE code in one or more of our SQL Server databases.To begin with, let's create a Table Def object and assign it to a specific table in the collection.Once we have done that, we can access its properties.Since customers don’t usually like to expose their databases to the internet, we are proposing a separate server that contains no actual data and only contains the views necessary for applications to get an internet link to SQL Azure databases.Using the check constraints on the tables as shown in the examples in this link is essential if you want the optimizer to only touch the right tables when you use the constrained columns in a WHERE clause in your queries.The download for this article, when unpacked correctly, demonstrates how your database application can relink to the data tables, provided the back end MDB file is where it is expected to be.The sample code in the download demonstrates the following: What this demonstration omits is a method for navigating to a datasource.Tip: You might want to back up your database before you run an update query.You cannot undo the results of an update query, and making a backup helps make sure that you can reverse your changes if you change your mind.
