Useful MSSQL Queries and Statements

Although I primarily use MySQL on linux servers, I’ve had a couple clients using MSSQL databases for all sorts of things from email marketing to order tracking. For these clients, I use Microsoft SQL Sever Management Studio Express and have saved many of the MSSQL queries I’ve had to create. Some of these will work fine in MySQL as is or with minimal tweaking.

Here’s a collection of the useful MSSQL Queries I’ve used and saved. This is by no means a comprehensive list of all the MSQL Queries and MSSQL statements, but I hope they can be useful for you.

MSSQL Variables

Being able to declare MSSQL Variables has saved so much time for sets queries that I need to run multiple times with slight variations.

This is a very basic example, but has everything you need. MSSQL Variables must begin with a “at symbol” (@). You first declare the MSSQL variables and assign it a character type (in this case, I’m just using varchar(55). 55 is the maximum number of characters to be stored in the variable. Then you set a value for the variables.

Declare @email1 varchar(55), @name1 varchar(55)
set @email1 = ‘’
set @name1 = ‘%Ashton Sanders%’

FROMÂ Â email_database
WHERE email_address LIKE @email1
AND first_name LIKE @name1
