View 9 RepliesI am now able to add a row to Table1 in my database and and to populate some text boxes with that data. Now...one of those text boxes has a piece of data I wish to use as a variable/parameter in a SQL query to then populate several other text boxes. The piece of data in question is the Primary Key in a Table2. I have tried several methods I've discovered online...but nothing is working so far.

I am connected to a SQL Server Compact Edition Database. One of the tables involved has 3 columns - CompanyID, CompanyName and CompanyNotes. I have created a form in Visual Basic to add a new company to the database, and of course I don't want the user to have to manually put in the company ID.
In the dataset.xsd I have created an INSERT SQL query that simply inserts a new row with the CompanyID, CompanyName and CompanyNotes. I have set the CompanyID to auto-increment. However, when I tried inserting the name and notes it didn't like it because I set the ID field to be mandatory. How will I insert the new company data into a new row with a new ID?
