SQL to VB object

Hello,

I have a schema SQL (DDL).  It will likely change a lot (i.e. entities and relationships will be added and removed).  I am going to use the schema for a file structure definition and I would like to have a VB object/s created for interfacing the file.  Do you know of any quick ways to generate VB objects from a SQL definition?

E.g. SQL input:

CREATE TABLE A
 (ID NUMBER
 ,DATA VARCHAR2(4000)
 )

VB object output (A.cls file):

Private ID As Integer 'local copy
Private DATA As String 'local copy
Public Property Let time(ByVal _ID As integer)
    ID = _ID
End Property

Public Property Get ID() As Integer
    ID = ID
End Property

If you are using SQL Server you can do this with DTS.  What is your database?

Actually, there is no database.  The data design was just done in a ER modeling tool.

The only way soemthing like this is possible is by launching another tool/process or something else, which is database specific.  So for example you may be able to execute xp_command_shell (or a similar system store proc) in Sybase or MS SQL Server, or you can utilize Perl/Java/VBScript ot whatever the database may support.  However, there is no direct way to "generate VB objects from a SQL".

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Maybe I need to rephrase the question:

I want to create VB classes (source code), not objects (instants of classes) from SQL.

Give me an example of what it would look like if it waqs possible?  I am having a hard time visualizing this.

Well, I guess you can create SQL code which will generate VB code and retrieve the result into a text file, but it will not be simple.

It seems to me that it would be easier to start in VB and have your code create a table in SQL Server and then create your class.

Yeah,

I think my current approach (below) is better.  

Have a Perl script to convert SQL to VB code.

Just thought someone might know of a tool that already does this.

Well, you are using the same method as i suggested above, just that you are starting from Perl instead of VB.  I am pretty sure that no such tool exists.
