Modified sp_who - more info & extra parameter
This procedure, sp_who3, is based on the system-supplied sp_who2, but is modified to return the actual text of the commands executed by each spid. Very helpful for troubleshooting! In addition, I have added a @hostname parameter to allow the user the option of viewing activity originating from only one computer, if desired.

Parsing an IP address into its separate octets
IP addresses are represented as xxx.xxx.xxx.xxx, where xxx is an integer between 0 and 255. Each three-digit integer is called an octet, and all IP addresses comprise four octets.Help-desk applications and administrative tools often store the IP addresses for a company's PCs in a database. An IP address can be represented either as a single […]

Execute VBScript commands or .vbs files via T-SQL.
sp_ExecVBScript allows you to execute either a .vbs file or an ad-hoc VBScript command within a T-SQL batch. Note that the command (whether it be ad-hoc or contained in the .vbs file) cannot have any code that requires user input (such as Input Boxes or Message Boxes).

Creating a Dynamic Crosstab Query
Crosstab queries (also called "pivot tables") in which you know beforehand the number of column values to aggregate by, can easily be performed in T-SQL using CASE statements wrapped in the SUM function. Where things get tricky, however, is when you don't know how many aggregation values exist, and you are required to write a […]

A faster way to count rows in a table
SQL Server includes the COUNT function for counting a table's rows - however, it can be slow. Although querying the "rows" column from the sysindexes table is faster, it is not always accurate (e.g., if a bulk load process has recently taken place). In addition, you would not be able to use this method in […]

A more efficient ForEach routine
SQL 2000's sp_MSForEachDB and sp_MSForEachTable are useful procedures for performing operations against multiple objects; however, they aren't always extremely efficient, because internally they use cursors to do their work.These 2 sprocs, sp_ForEachDB and sp_ForEachTable, perform many of the same tasks as their Microsoft-shipped twins, but run faster because they dynamically build the SQL string without […]

An alternative to self-joins
Oftentimes there is a need to retrieve different types of the same object (e.g. contacts). For example, in a Contacts database, you might have a Contact table containing many different types of contacts (employees, customers, suppliers, etc). Typically, a user might need to see a report of all different types of contacts for an order […]
