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
...

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".

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.
