Accessing and Changing Database Data

Query Tools

Describes the different classes of tools used to work with SQL Server.

Selecting a Database

Describes how SQL Server determines which database contains a specified object.

Using Options in SQL Server

Describes the various options that affect the result and performance of SQL statements.

Elements of Transact-SQL

Describes the primary syntax elements used in Transact-SQL statements.

Query Fundamentals

Describes the fundamental processes of building Transact-SQL statements. Describes the main clauses used in the SELECT, INSERT, DELETE, and UPDATE statements:

• Select list

• FROM clause

• WHERE clause

• ORDER BY clause

• JOIN clauses

Manipulating Result Sets

Describes how to manipulate and control the results of queries by combining result sets and views, working with temporary result sets, producing summary reports of result sets, and sending notifications when result sets change.

Changing Data in a Database

Describes the methods for inserting new rows, and updating or deleting existing rows.

Procedural Transact-SQL

Describes the methods for grouping Transact-SQL statements.

Transactions (Database Engine)

Describes how several data modification statements can be grouped in a transaction.

Locking and Row Versioning

Describes how SQL Server prevents multiple users from modifying the same data at the same time.

Cursors (Database Engine)

Describes how SELECT statements always return a set of rows, but applications sometimes need to go through the result set one row at a time. Cursors support processing a result set one row, or a block of rows, at a time.

Distributed Queries

Describes how to code Transact-SQL statements that reference data on separate instances of SQL Server, or even in non-SQL Server OLE DB or ODBC data sources.
