If you do not have a solid background in SQL, I will be breaking down the statements before moving on. It is expected that you have a basic knowledge of SQL and its workings for the information and case studies with this AppNote. This AppNote is not designed to give you full working knowledge of SQL, as there are many text resources on this topic as well as many Internet sites that give a more thorough explanation of SQL and its syntax. This example retrieves all the fields from the data store where the fname field contains "Bob" and the lname field contains "Myers". SELECT * WHERE fname = 'Bob' and lname = 'Myers' An example of a SQL statement would look like this: This language was designed to allow users to access databases using simple English commands. SQL is an acronym for Structured Query Language.

We will be focusing primarily on the use of SQL inside Microsoft Visual Basic using RDO objects, as the ODBC driver does not function well with Microsoft's ADO objects. Also covered in greater detail will be some of the finer points to remember when building a query. A section of this article is on how the ODBC driver maps the NDS tree. This article will get you started with SQL and how you can build queries using SQL to retrieve information from the NDS tree. One of the most important facets of the ODBC driver is the ability to use SQL to query the tree. This information will be expanded on in greater detail in this article.

We also showed you how to build a simple report in Microsoft Excel using a driver and DSN connection. In Part 1 we introduced the NDS ODBC driver. Displaying the NDS Tree Using SQL Queries.This AppNote, the second in a three-part series, addresses how to integrate the ODBC driver to assist in making reports on network use polled from the NDS tree.
