Cathan Kirkwood

Started working with databases in 1984. Clients have kept pushing me into front end programming over the years, giving me a widely varied background in VB, ASP, HTC, SQL, DHTML, COM, RPG, Cobol, Fortran (how many people know what .HTC is anymore...grin). I've worked with SQL Server in particular since version 4.2 was released. I've worked with DB2, AS\400's, Sybase, Oracle, Informix, Alpha4 & 5, Access (all versions to date.) (Boy, I almost didn't even mention that one.), and a lot of databases which people still debate as to whether they were even databases or not. Hold a lot of different certificates I got before I realized how little they matter.

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;
