looking to write my own simple SQL Client via TCP/IP

I'm looking to write my own simple SQL Client via TCP/IP. We have some hardware that does not run an OS of sorts, but I can create TCP Connectons. We's like to be able to Query our SQL Server with this hardware.

The SQL Servers we are talking to are MS SQL2000 and MS SQL 2005 both via TCP port 1433. We can telnet to the port of the SQL Server. Any resources to the SQL Protocol you could pass along would be great.

Thank you,

Hi Scott,

In order to create an application driver that can send requests and receive responses from a SQL Server instance, your application must be able to communicate using the Tablular Data Stream (TDS) protocol. The MS TDS protocol is a proprietary protocol and must be licensed from Microsoft. If this interests you, then please let me know and I'll send you information on getting started.

Thanks,

Its not too proprietary since there are Linux and Java versions of the TDS Protocol out there with the Source? If its not too much trouble wont hurt to see whats involved in geting the License for the Protocol.

I've found the Following on TDS since I did the original Post:

http://en.wikipedia.org/wiki/Tabular_Data_Stream

http://www.freetds.org/

http://jtds.sourceforge.net/

I'm sure the MS version of it is more full featured when communicating to MS SQL 2005, though I jsut need to return a few Select statements.

I was thinking It might be easier to send a HTTP Request to IIS on the SQL Server and send the Select statement as a parameter and return the Data. I'm looking for something pretty simple as the hardware playform I'm working with is pretty limited.

Thank you,

Hi Scott,

Yes, there are free implimentations available although none are endorsed by Microsoft and they are typically based on reverse-engineering efforts. If you'd like to license TDS start with the MS IP Licensing website (http://www.microsoft.com/about/legal/intellectualproperty) and search for TDS.

Alternatively, if your can send HTTP requests from your hardware platform, you can take advantage of the fact that SQL Server 2005 can active as a native web service for SOAP applications. Take a look at the following documentation for more info:
