Dear friends,
I get the following exception
unhandled error from mysql_next_result()
on closing odbc reader. Could anybody tell me please what is wrong? Here is the code:
int inserted = 0;
int updated = 0;
int rowCounter = 0;
OdbcDataReader odbcReader = null;
try

odbcCommand.CommandType = CommandType.StoredProcedure;
if (odbcConnection.State == ConnectionState.Closed)
odbcConnection.Open();
