SQL 2000/2005 Transaction Log Reader Library

Feris T

Hi,

Is there any development library exist in the market for SQL Server
2000/2005 transaction log reader ? I need to use it for Capture Data
Change (CDC). Preferably Java.

Regards,

Feris

Hi Feris,

I don't know who told you that data capture change using log is the most
accurate, but he was either not talking about SQL Server but about some
other database, or flat out wrong. (Or both). Microsoft has never
released documentation about the format of the log file, and there are
no libraries available for this.

Is there
any other workaround with SQL Server 2000/2005 ?

Probably, but since I'm unfamiliar with both data warehousing and with
ETL tools, I suggest you to post a new question. Probably best in a more
specialised newsgroup, such as microsoft.public.sqlserver.datawarehouse.

It's difficult to say that something is accurte, when it is not supported.

There are third-party products out there that read the looks, but I
don't think they come with an API.

If you want to use CDC, I think your best option is to move to SQL 2008
which has such a feature.

Isn't it ? As the most accurate change for sophisticated database
system is resided in it's log.

It is based on this product that I come to a thinking of the same
workaround solution for previous version. Anyway, thanks Erland for
the update.
