Is it possible to capture delta for a specific table or capture DML statement
executed against a specific table?
thanks

With SQL Server, you get SQL Profiler that enables you to catch any
statement sent to SQL Server, including DML statements. Findind differences
in data is quite simple, if you have a stable PK and a timestamp column.
Anyway, you can help yourself with 3rd party tools as well. Some of them
include:
- Red-Gate SQL Compare (http://www.red-gate.com/) helps you comparing the
schema
- Red-Gate SQL Data Compare (http://www.red-gate.com/) helps you comparing
the data
- Lumigent AuditDB helps you with auditing (http://www.lumigent.com/) -
easier than Profiler

The SchemaCrawler tool helps you compare the schema and data of a
database with a reference version. SchemaCrawler outputs details of
your schema (tables, views, procedures, and more) in a diff-able
plain-text format (text, CSV, or XHTML). SchemaCrawler can also output
data (including CLOBs and BLOBs) in the same plain-text formats. You
can use a standard diff program to diff the current output with a
reference version of the output.

SchemaCrawler is free, open-source, cross-platform (operating system
and database) tool, written in Java, that is available at SourceForge:
http://schemacrawler.sourceforge.net/
You will need to provide a JDBC driver for your database. No other
third-party libraries are required. A lot of examples are available
with the download to help you get started.

Well, Infact I need to capture delta so I can publish it or apply it to the
datawarehouse. Is there any other effective way to do this?
Thanks

Shahab,

In fact, SchemaCrawler, when coupled with any standard diff tool will
help you to capture and publish the diffs. Am I missing something in
your use case?

Seems like schema crawler takes the whole schema. Whereas I am concerned more
with a few defined tables. Hope this clearifies the confusion.

In fact, with SchemaCrawler you can specify exactly which tables, and
which columns are you interested in. Please look at the how-to section
of the website.

Have you thought about putting a trigger on the table that is changing
and having it output the delta to another table?
