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
{
String odbcConnString = WebConfigurationManager.ConnectionStrings["BookList"].ToString();
odbcConnection = new OdbcConnection(odbcConnString);

OdbcCommand odbcCommand = new OdbcCommand("{ CALL InsertBookQuest(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) }", odbcConnection);

odbcCommand.CommandType = CommandType.StoredProcedure;

if (odbcConnection.State == ConnectionState.Closed)
odbcConnection.Open();

for (rowCounter = 0; rowCounter < sheetEntries.GetLength(0); rowCounter++)
{
odbcCommand.Parameters.Clear();

OdbcParameter odbcParameter = odbcCommand.Parameters.Add("pEAN", OdbcType.VarChar, 13);
odbcParameter.Value = sheetEntries[rowCounter, 0] == "" ? (object)DBNull.Value : sheetEntries[rowCounter, 0];
odbcParameter = odbcCommand.Parameters.Add("pTitle", OdbcType.VarChar, 255);
odbcParameter.Value = sheetEntries[rowCounter, 1] == "" ? (object)DBNull.Value : sheetEntries[rowCounter, 1];
odbcParameter = odbcCommand.Parameters.Add("pRespParty", OdbcType.VarChar, 255);
odbcParameter.Value = sheetEntries[rowCounter, 2] == "" ? (object)DBNull.Value : sheetEntries[rowCounter, 2];
odbcParameter = odbcCommand.Parameters.Add("pPublisher", OdbcType.VarChar, 255);
odbcParameter.Value = sheetEntries[rowCounter, 3] == "" ? (object)DBNull.Value : sheetEntries[rowCounter, 3];
odbcParameter = odbcCommand.Parameters.Add("pPubDate", OdbcType.SmallDateTime);
odbcParameter.Value = sheetEntries[rowCounter, 4] == "" ? (object)DBNull.Value : Convert.ToDateTime(sheetEntries[rowCounter, 4]);
odbcParameter = odbcCommand.Parameters.Add("pSubject", OdbcType.VarChar, 255);
odbcParameter.Value = sheetEntries[rowCounter, 5] == "" ? (object)DBNull.Value : sheetEntries[rowCounter, 5];
odbcParameter = odbcCommand.Parameters.Add("pBinding", OdbcType.VarChar, 45);
odbcParameter.Value = sheetEntries[rowCounter, 6] == "" ? (object)DBNull.Value : sheetEntries[rowCounter, 6];
odbcParameter = odbcCommand.Parameters.Add("pPageCount", OdbcType.Int);
odbcParameter.Value = sheetEntries[rowCounter, 7] == "" ? (object)DBNull.Value : Convert.ToInt32(sheetEntries[rowCounter, 7]);
odbcParameter = odbcCommand.Parameters.Add("pUSListPrice", OdbcType.Double);
odbcParameter.Value = sheetEntries[rowCounter, 8] == "" ? (object)DBNull.Value : Convert.ToDouble(sheetEntries[rowCounter, 8]);
odbcParameter = odbcCommand.Parameters.Add("pDemand", OdbcType.Int);
odbcParameter.Value = sheetEntries[rowCounter, 9] == "" ? (object)DBNull.Value : Convert.ToInt32(sheetEntries[rowCounter, 9]);
odbcParameter = odbcCommand.Parameters.Add("pOnOrder", OdbcType.Int);
odbcParameter.Value = sheetEntries[rowCounter, 10] == "" ? (object)DBNull.Value : Convert.ToInt32(sheetEntries[rowCounter, 10]);
odbcParameter = odbcCommand.Parameters.Add("pOnBackorder", OdbcType.Int);
odbcParameter.Value = sheetEntries[rowCounter, 11] == "" ? (object)DBNull.Value : Convert.ToInt32(sheetEntries[rowCounter, 11]);
odbcParameter = odbcCommand.Parameters.Add("pStatus", OdbcType.VarChar, 45);
odbcParameter.Value = sheetEntries[rowCounter, 13] == "" ? (object)DBNull.Value : sheetEntries[rowCounter, 13];
odbcParameter = odbcCommand.Parameters.Add("pBTKey", OdbcType.Int);
odbcParameter.Value = sheetEntries[rowCounter, 14] == "" ? (object)DBNull.Value : Convert.ToInt32(sheetEntries[rowCounter, 14]);
odbcParameter = odbcCommand.Parameters.Add("pBTFirstPrinting", OdbcType.Int);
odbcParameter.Value = sheetEntries[rowCounter, 15] == "" ? (object)DBNull.Value : Convert.ToInt32(sheetEntries[rowCounter, 15]);

odbcReader = odbcCommand.ExecuteReader();

if (odbcReader.Read())
{
if (Convert.ToBoolean(odbcReader["IsInsert"]) == true)
inserted++;
else
updated++;
}

if (odbcReader != null && !odbcReader.IsClosed)
odbcReader.Close();

}
