In this article we would look at using SQL queries in Ms Access.

 

Ms Access Supports SQL with minor variances as compared to other databases like SQL Server

The best part about Ms Access is that it supports SQL to the fullest possible extent and both DML and DDL parts of SQL are supported. If you compare the Ms Access application to other databases such as Ms SQL Server and Oracle, you would find that Ms Access allows you to run nearly every query that can be processed on the other fancier RDBMS applications. However SQL in Ms Access has certain minor variances and in some cases it considered to be less robust.
