NET is that it’s very easy to create database access logic through program code. The BDP is a regular managed. This isn’t exhaustive, and is naturally simplified, but it should help you see where to start. Your ConnectionString can either be something like: As you might expect by now, the process for setting up the DB2DataAdapter is similar: The way that database access classes are specialized for each type of database server is one of the major features of the design of ADO. Here are a couple of important notes.

Create nil ; CS: So i thought dbexptess made something wrong in the connection string, but DNN created a lot of tables, views sbexpress stored procedures in the DB.

Database server rejected connection. Dbexpress connect to Db2 strange error [Edit]. IBM grants you “Licensee” cb2 non-exclusive, royalty free, license to use this sample code.
If this is done in the right way, the result is ‘business logic’ classes that handle all the database access, but which can be used throughout the application. Secondly, you need to explicitly cast the parameters to the particular underlying data type that’s expected by the server.
Here’s where there are some differences between the Dbexperss and the other flavors.

Here are a couple of important notes. This example shows how to use parameters in the SELECT query-it’s a very similar process to that used for stored procedures. Embarcadero Delphi – Wikipedia, the free encyclopedia To create applications for managed code platforms, a similar but not mutually compatible alternative is Delphi Prism.

There are plenty of alternative options, but all of them depend on code. You can only step forward, reading one record at a time, and there’s no caching of data. Because it has also to map the different data types to the.
Instead, a current record pointer is managed by the data-binding layer. This approach is quite different from the BDE and dbexprress, which uses the TQuery and TSQLQuery components to call stored procedures or other data-definition queries, which don’t return a tabular result set. A great side-effect of this is that the DataSet can be populated at design time, showing live data!
