I have a routine in a custom class that is assigning values to an object based on data from a table row. However, several tables may be used to update these values and only have some of the fields in common. Therefore, I want to check each field value to make sure it exists before I attempt to access it's value to assign to my object. However, I am getting the error "Column x Does Not Belong To Table."

View 10 RepliesI'm using parameters on a SQL stored procedure to insert a record with data entered on a website form (and on the form I'm using VB.net). As of right now, the form works perfectly; the record is inserted. However, after the user hits the submit button, everything executes and then the page will basically refresh with emtpy values in all the fields. So I want to give the user some type of SUCCESS message, assuring the user the information was successfully entered into the database. So my question is: How can I verify that the record insertion was successful? I want to do this with the ExecuteNonQuery statement, because that's what I'm using.
Code is below:
If Page.IsValid then
Dim MyConn as SQLConnection= New SQLConnection("Blah")
Dim MySQL As SQLCommand
MySQL= New SqlCommand("proc_newWebEntry", MyConn)
MySQL.CommandType = CommandType.StoredProcedure

I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.
