Switching from access to sql server express in vb2005
- 0
Right now im using an access database wich i connect to with oledb in VB2005. Now if in my whole program i want to change the database to sql server, is enough to just use sql instead og oledb (for example sqlcommand instead of oledbcommand, and slqconnetion instead of oledbconnection)?
Or is there something else you need to be carefull with?
To my understand, the sql language is almost the same so that shouldnt be a problem..

Hi,
Some of the concepts of access and sql server do not have a one to one mapping. If you don't have migrated the database schema already to access to can use the upscaling wizard in the tool menu of Access or the newer Sql Server Migration Assistant for Access:

Many thanks in advance.

Assuming that the database schema is (almost) the same in your SQL Server db than in Access, you just have to create a new dataset and configure it exactly like the Access dataset, but using the SQL Server tables and in a different vb namespace.
If all the object names are the same, it would then be a matter of going through your program to change the namespace imports to point to the new dataset.
