Stairway to Advanced T-SQL Level 4: Record Level Processing Using Transact-SQL Cursors

Using a CURSOR is not normally the best way to process through a set of records. Yet when a seasoned programmer moves to writing TSQL for the first time they frequently look for ways to process a sets of records one row at a time. They do this because they are not used to thinking about processing records as a set. In order to process through a TSQL record set a row at a time you can use a cursor. A cursor is a record set that is defined with the DECLARE CURSOR statement. Cursors can be defined as either read-only or updatable. In this article I will introduce you to using cursors to do record level processing one row at a time.

Stairway to T-SQL DML

Stairway to T-SQL DML Level 5: The Mathematics of SQL: Part 2

Joining tables is a crucial concept to understanding data relationships in a relational database. When you are working with your SQL Server data, you will often need to join tables to produce the results your application requires. Having a good understanding of set theory, and the mathematical operators available and how they are used to join tables will make it easier for you to retrieve the data you need from SQL Server.

Stairway to T-SQL DML

Stairway to T-SQL DML Level 4: The Mathematics of SQL: Part 1

A relational database contains tables that relate to each other by key values. When querying data from these related tables you may choose to select data from a single table or many tables. If you select data from many tables, you normally join those tables together using specified join criteria. The concepts of selecting data from tables and joining tables together is all about managing and manipulating sets of data. In Level 4 of this Stairway we will explore the concepts of set theory and mathematical operators to join, merge, and return data from multiple SQL Server tables.
