William Brewer takes a look at the whole topic of SQL Code layout and beautification, an important aspect to SQL programming style. He concludes that once you are tired of laying SQL out by hand, you had better choose a tool with plenty of knobs to twiddle, because nobody seems to agree on the best way of doing it.

Database systems like Microsoft® SQL Server® have long supported triggers—developer-created scripts that automatically execute after or in place of INSERT, UPDATE, and DELETE statements. Because triggers can access the data modified by INSERT, UPDATE, or DELETE, they are an excellent tool for recording data changes to an audit log.

The SQL (Structured Query Language) language is a declarative language that became the "Data Language" used for describing "what I need" and "where to fetch it from" in most organizations.

Every day, out in the various discussion boards devoted to Microsoft SQL Server, the same types of questions come up again and again: Why is this query running slow? Is my index getting used? Why isn't my index getting used? In order to arrive at the answer you have to ask the same return question in each case: have you looked at the execution plan?

I would like to share some interesting parameters I found for the undocumented extended stored procedure xp_ReadErrorLog.

I have heard that Full Text Search uses a noise words to eliminate meaningless words in searches. I have also heard that a thesaurus is used, but I am not exactly sure how. Can you provide some details related to how both of these technologies are used in Full Text Search? I am interested in more of a background on these specific Full Text Search technologies as well as where the files are located and how I can update them.

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;See possible answers
