Error in executing an OleDbCommand.. “Must declare the scalar variable ”@MaxID“.”

Question

private void AddValue(string strValue)

{

      //get the maximum id for Lists first

      int MaxID = DataOperations.ReturnMaxIDInATable(\"Lists\", connString);
          


        

Answer 1

I believe you need to use question marks for the parameters when executing SQL through the OleDbCommand (while SqlCommand uses @). Example:

INSERT INTO Lists (ID, ListName, ListValue) VALUES (?, ?, ?)

You only need to Add the Parameters in the order that they appear in the SQL.
