Note
The ExecuteNonQuery() method used to query the database returns an int32 with the number of rows affected by the query. The maximum size of an int32 type is a constant and is defined to be 2,147,483,547. If your query returns more results than the int32 max, then ADO.NET throws an exception because of the overflow of the int32 type. However the query is still processed by Vertica even when the reporting of the return value fails. This is a limitation in .NET, as ExecuteNonQuery() is part of the standard ADO.NET interface.
