Robert Marda

I have worked for bigdough.com since 18 May 2000 as an SQL Programmer. My duties include backup management for all our SQL Servers, mentoring junior SQL Programmers, and serving as DBA while our DBA is on vacation. I develop, test, and deploy stored procedures and DTS packages as well as manage most major SQL projects. Our offices are located in Bethesda, Maryland. Before working for bigdough, I worked for Telos Corporation in Ashburn, Virginia. I started learning T-SQL and using SQL Server 7.0 on 22 March 1999. In April 1999 I was given the position of Senior Database Analyst/Administrator at Telos Corporation. I have been married to Leoncia Guzman since 23 Jul 1994. We met in the Dominican Republic where I lived for about 2 years as a missionary. We have 4 children, Willem (age 8), Adonis (age 6), Liem (age 4 and a half), and Sharleen (age 3 and a half). My hobbies include spending time with our 4 children (we play chess, dominos, mancala, and video or computer games together), keeping tropical freshwater fish, breeding and training parakeets, coin collecting (US and foreign), and geneology. I have a 55 gallon tank and 20 gallon tank. I have many kinds of fish (such as a pleco, tiger barbs, mollies, cichlids, tetras, and guppies) I also have a small aquatic turtle. I last updated my bio 30 Mar 2004.

Question of the Day

The "ORDER BY" clause behavior

Let’s consider the following script that can be executed without any error on both SQL Sever and PostgreSQL. We define the table t1 in which we insert three records: 

create table t1 (id int primary key, city varchar(50));

insert into t1 values (1, 'Rome'), (2, 'New York'), (3, NULL);
If we execute the following query, how will the records be sorted in both environments? 
select city

from t1

order by city;
