You could use ODBC and let it translate a query to the native SQL implementation.
There is no real SQL Standard as all manufacturerts, from MS SQL Server to Oracle to IBM to MySQL, etc. have added their own little enhancements.

If you write the statements yourself, using SQL Pass-Through you are basically sending the command unchanged/unstranslated by the ODBC Driver (or oleDB Provider if you used ADO). Therefore your data access layer would have to be smart enough to be able to switch. In .NET they somehow solved it by giving you different provider (generic, SQL Server, Oracle). In reality you have to know more about what back-end database you are dealing with.
