Log4net doesn't write to DB

Question

For the past few hours I've been trying to get a log to write to a table in a database.

After turning debugging on, I received the following error statement: SqlCommand.Prepare method requires all variable length parameters to have an explicitly set non-zero Size

Here are my snippets:

Config section:

And the Class:

ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
            log4net.Config.XmlConfigurator.Configure();
            log4net.Util.SystemInfo.NullText = null;

            GlobalContext.Properties["UserName"] = userName;
            GlobalContext.Properties["ProcessModeID"] = processModeId;
            GlobalContext.Properties["CcCompanyNameID"] = ccCompanyNameId;
            GlobalContext.Properties["CcExpDate"] = cCExpDate;
            GlobalContext.Properties["CcID"] = ccId;
            GlobalContext.Properties["CcOwnerID"] = ccOwnerId;
            GlobalContext.Properties["CcOwnerName"] = ccOwnerName;
            GlobalContext.Properties["InvoiceDate"] = invoiceDate;
            GlobalContext.Properties["CustomerNo"] = customerNo;
            GlobalContext.Properties["SumWithDue"] = sumWithDue;
            GlobalContext.Properties["SumWithoutDue"] = sumWithoutDue;
            GlobalContext.Properties["PaymentTypeID"] = paymentTypeId;
            GlobalContext.Properties["TaxRegistrationNum"] = taxRegistrationNum;
            GlobalContext.Properties["TrxUniqueID"] = trxUniqueId;
            GlobalContext.Properties["SalesPerson"] = salesPerson;

            log.Debug(string.Format("UserName: {0}, ProcessModeID: {1}, CcCompanyNameID: {2}, CcExpDate: {3}, CcID: {4}, CcOwnerID: {5}, InvoiceDate: {6}, CustomerNo: {7}, SumWithDue: {8}, SumWithoutDue: {9}, PaymentTypeID: {10},"
                                    + "TaxRegistrationNum: {11}, TrxUniqueID: {12}, SalesPerson: {13}", userName, processModeId, ccCompanyNameId, cCExpDate, ccId, ccOwnerId, ccOwnerName, invoiceDate, customerNo, sumWithDue, sumWithoutDue,
                                    paymentTypeId, taxRegistrationNum, trxUniqueId, salesPerson));

No errors are shown in Output window.

Any help would be appreciated.

Can you try giving the size to all your string parameters as below? The size should match the actual size in the database.

     <parameter>
        <parameterName value="@CustomerNo"/>
        <dbType value="String" />
        <size value="50" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%property{CustomerNo}" />
        </layout>
      </parameter>

Ok, I'm one step forward, I need to set the precision and scale of my decimals, could you help with the syntax please? – Ilan Ezersky Jul 16 '14 at 07:01
Generally for the fixed size data types(int,decimal,bit etc) you dont need to specifiy the size – Kiran Hegde Jul 16 '14 at 07:09
Well, I did append the scale and precision, it did work. Now I'm getting System.FormatException: Failed to convert parameter value from a String to a Int32. ---> System.FormatException: Input string was not in a correct format. – Ilan Ezersky Jul 16 '14 at 07:23

I've solved the problem by Adding the precision and scale to my decimals and adding size to strings. In addition, I missed one colon in my query. Thanks guys for your support!
