I am developing an application in C# VS 2010 past 4 months. I used MS Access 2007 to store my nearly 20 tables successfully.

Today I realized that my data base cannot be handled consistently by MS Access 2007. Hence I decided to go for SQL Server 2008 R2 Express with Upsizing wizard and it worked really great!

However, when I tried to run various options of my already well developed application, It kept throwing error each time when a query is fired to SQL Server.

I understood that Many of the stuffs of SQL supported by MS Access are not supported by MS SQL Server

For example: query with date, for representing date format when we use ‘#’, SQL Server 2008 won’ t recognize it.

Also, for Bool value, MS Access stores it as True and False where as SQL Server uses 0.

These all queries worked perfect with Access 07

I am sure that there must be some method so that SQL Server can understand MS access queries.

Or will I have to edit my whole application?? It will be as good as digging a mine for earning gold..

I have changed all data access objects such as reader, adapter, command, connection to SQL data objects using System.Data.SqlClient.

So, It is not the problem.

Please help me asap.

Thank you.

    You cannot force SQL Server to run the MS Access queries. These queries will need to be rewritten to use T-SQL instead of the query language that MS Access uses.

    I feel your pain, I just had to rewrite a large MS Access application (over 1k queries) that needed to be recreated to be used in SQL Server.

    There will be some queries that might be able to be ported over directly but as you noticed queries with date, and even some of the aggregate functions (First(), etc) are not used in SQL Server and those queries will need to be changed.

    Here is a link with some info on converting Access to SQL
