There is an ANSI standard for SQL that's (mostly) supported by most database servers. As long as you stick to that subset of the SQL language functionality offered by your database server your queries will be portable.
However, many of the more sophisticated features of your dbms won't be usable as they are not part of the ANSI standard, and thus implemented in a proprietary way by each dbms vendor - crosstabs are an example of this problem.

We are looking for a common language for any RDBMS technology. I mean if I write a query in SQL Server that query will also have to work on any RDBMS like oracle, sql">mysql etc.
Can anyone help get me started?
