This will open the “Connect to Server” dialog as shown in Figure 1.From here you will need to make sure that the Server name and Authentication method are correct and press the “Connect” button.We will use in our samples the classes from both models. Rows(3)("DName") = "Researches" ' Update method executes the appropriate commands (delete, insert, or update) in the data source. Please refer to our Using Data Set Wizard and Using Data Set Manager articles.The goal of this tutorial is to retrieve and update the data from the table dept (the appropriate DDL/DML script is located at \Program Files\Devart\dot Connect\DB2\Samples\- the default path of dot Connect for DB2 installation). NET Standard 1.3 compatible assemblies, because there are no base classes for them. This tutorial describes only basic ways of working with data.The purpose of this article is to assist the Visual Basic developer in choosing the proper cursor location, cursor type, and lock type to use when programming Visual Basic (or VB) applications that use My SQL as a back-end database through ADO and Connector/ODBC (My ODBC).
This sample requires the latest version of Connector/ODBC (My ODBC), available for download here (currently 3.51.06). NET (Unless you reference ADODB in your project and use it for database access).
You can use classes of the connected model for establishing connection and setting transactions, for fetching data and updating datasources. Here is a small sample that demonstrates usage of DB2Data Table.
These classes interoperate with database directly: DB2Provider Factory, DB2Connection, DB2Transaction, DB2Data Adapter, DB2Command, DB2Parameter, and DB2Data Reader. Module Module1 Sub Print Dept(By Val connection As DB2Connection) Dim command As DB2Command = connection. Command Text = "select * from dept" ' Call the Close method when you are finished using the DB2Data Reader ' to use the associated DB2Connection for any other purpose. Public Sub Use Data Table() Dim my Data Table As DB2Data Table _ As New DB2Data Table("SELECT * FROM Dept", "user id=db2admin;server=db2;database=SAMPLE;") Try ' Fetch All=true means to retrieve data from server entirely when Data Table is opened.
In order to determine which is the fixed currency when neither currency is on the above list (i.e.
both are "other"), market convention is to use the fixed currency which gives an exchange rate greater than 1.000.
