Internally, in most cases, the BDP calls the same native client libraries as the server-specific components, so it’s just as fast. The parameter classes are, yet again, implemented on a server-specific basis. Here is an example of parameters, which calls a DB2 stored procedure to return the full name from a database, given an email address. Create nil ; CS: Cannot open database ” databasename ” requested by the login.

Thanks for all help.
This is installed by default in C: The DataSet manages data internally as a relational view into an XML schema, so as a result it doesn’t have a concept of a ‘cursor’ or current record.
You can set the ConnectionString property when you develop your application using the IDE, or you can set it in code. Another difference is the technique used to handle updates. The examples I just listed for the DbCommand classes didn’t return a data set.
Login failed for user ‘ localASPaccount ‘. All i changed in web. We create the connection, create a command, then create two BdpParameter objects and add them to the command object. Software Development dg2 ZDNet New frameworks are emerging to give developers multiple tools to invent the future. Here is an example of parameters, cb2 calls a DB2 stored procedure to return the full name from a database, given an email address.
That’s what the DataSet object can do.
So what is happening here? There’s a BDP equivalent too, so.
The trick is accomplished through interfaces that define the database-specific classes. Embarcadero Delphi – Wikipedia, the free encyclopedia Delphi was originally developed by Borland as a rapid application development tool for Windows, and as the successor of Borland Pascal.
Roman Dukuy on Nov 23, 4: But this is what I am concerned about.
However, under the surface the TClientDataSet is very different. Cannot open database ” databasename ” requested by the login. Once you understand the program code and in particular the subtleties of interfaces and classesit’s then quite simple to write ‘wrapper’ classes around the database access logic.
For example, the DB2Connection component includes an additional method that can be used to force connection pool resources to be released. Web resources about – Dbexpress connect to Db2 strange error [Edit] – dbexprees. You’ll need to add the Parameter objects to the Command.
The first class returns a database connection object. What is the diference between “dbExpress” and an ADO connection?
Since you are using iis instead of the built in web host you are going to have to go into Dbb2 manager an And how are you connecting to it? It mostly works fine. The actual driver is determined through the connection string passed to the BdpConnection object when it is created or the ConnectionString property. Regards, Beverly Beverly, First of all, what database server are you using? Database server rejected connection.
Your ConnectionString can either be something like: She modified the code page settings and after fixing several data access issues we got it to connect. NET is a rich, sophisticated database access library.
I am happy to say that we were able to successfully connec to to the DB2 database.
