Hi everyone.

I need copy picture from one DB to another. 

InventItemImage table have 3 field. Format - Enum, Image - Bitmap and ItemId - str.

I try 

loginProperty    = new LoginProperty();

        loginProperty.setServer  (systemParameters.Ax4ServerName);
        loginProperty.setDatabase(systemParameters.Ax4DatabaseName);

        odbc =  new ODBCConnection(loginProperty);

        if(odbc)
        {
            binData = new BinData();

            statement       = odbc.createStatement();

            queryText   = strfmt(<>);

            perm = new SqlStatementExecutePermission(queryText);
            
            perm.assert();

            odbc.ttsbegin();

            resultSet = statement.executeQuery(queryText);
            CodeAccessPermission::revertAssert();

            resultSet.next();

            inventItemImage = InventItemImage::findOrCreate(_inventTable.ItemId, InventItemImageFormat::FullAx, true);
            
            // in this place i can't get picture from resultSet

            odbc.ttscommit();

            inventItemImage.Image = binData.getData();
            inventItemImage.update();

            _inventTable.IsImage = NoYes::Yes;
            _inventTable.update();

I try another

sqlConnection = new System.Data.SqlClient.SqlConnection(strFmt("Data Source=%1;Initial Catalog=%2;Integrated Security=True",
        systemParameters.Ax4ServerName,
        systemParameters.Ax4DatabaseName));

    queryText   = strfmt(<>);

    sqlCommand    = new System.Data.SqlClient.SqlCommand(queryText, sqlConnection);

    try
    {
        sqlConnection.Open();

        sqlCommand.ExecuteNonQuery();
        
        binData = new BinData();
       
        binData.setData(sqlCommand.get_Container()); 
// in this place i have error "setData Invoked with invalid parameters"

        sqlCommand.Dispose();

        sqlConnection.Close();
        sqlConnection.Dispose();

        ttsBegin;

        inventItemImage = InventItemImage::findOrCreate(_itemId, InventItemImageFormat::FullAx, true);

        inventItemImage.Image = binData.getData();
        inventItemImage.update();

        ttsCommit;
    }
    catch
    {
        info(CLRInterop::getLastException().ToString());
        sqlConnection.Close();
    }

Please help

    Let's focus on your latter attempt.

    If you want get data from the database, you must run a query, therefore using ExecuteNonQuery() won't help you. Use ExecuteReader() instead, which will give you SqlDataReader object. Use its Read() method to iterate records and the Item property to access columns. Of course, you'll need a meaningful select statement in your queryText variable.

    Thanks. Now code looks like

           Bitmap    image;

            .......        

           sqlConnection.Open();

           sqlDataReader = sqlCommand.ExecuteReader();     

           if (sqlDataReader.get_HasRows())

           {

               while (sqlDataReader.Read())

               {

                   idx = sqlDataReader.get_FieldCount();  // return '1' - it's true

                   fieldName = sqlDataReader.GetName(0);  // return 'Image' - it's true

                   //image = sqlDataReader.get_Item(0); // error "Wrong types"

                   binData = new BinData();

                   binData.setData(sqlDataReader.get_Item(0)); // error "invalid parameters"

                   .....

               }

    What am I doing wrong?

    SQL Server doesn't know anything about X++ Bitmap type, so it shouldn't be surprising that such an assignment fails.

    If you don't know what the type is, use GetFieldType(0), or assign a return value of GetValue() to a System.Object variable and check its type in debugger.

    I think you'll be able to assign the value to a variable of type System.Byte[].
