Partitioned indexes help improve query performance. To create a partitioned index, you need to perform the following tasks: Create a partition function. Create a partition scheme. Create a clustered index. Slide 3 Installing Windows XP Professional Using Attended Installation Slide 3 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 4 Knowledge Byte (Contd.) SQL Server 2005 provides a set of system-defined stored procedures used for general maintenance of a particular database or the database server in whole. Microsoft Word Document ¤NIIT Instructor Inputs 4.5 Slide 4 Installing Windows XP Professional Using Attended Installation Slide 4 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 4 Best Practices Keep the stored procedures as small as possible. This is useful in a situation where two users are accessing the same stored procedure at the same time and the two query plans are stored in the cache. Ensure that all stored procedures return a value indicating their status. This will help evaluate their success or failure status. While creating a view if the records are combined from multiple tables having different number of columns, you should use the UNION ALL operator. When performing any operation on a table, such as inserting columns in a table, keep refreshing the dependent views. Slide 5 Installing Windows XP Professional Using Attended Installation Slide 5 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 4 Tips and Tricks Use SET_NOCOUNT_ON at the beginning of SQL batches, stored procedures, and triggers. This will increase the performance by reducing network traffic. Use the following procedure to find keywords in stored procedures: CREATE PROCEDURE <proc name> @<var name> VARCHAR(100) AS SELECT routine_name FROM INFORMATION_SCHEMA.ROUTINES WHERE routine_definition LIKE '%' + @<var name> + '%‘ ORDER BY 4.6 Instructor Inputs ¤NIIT Slide 6 Installing Windows XP Professional Using Attended Installation Slide 6 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 4 Tips and Tricks (Contd.) Use catalog views to access metadata of different objects in SQL Server 2005. It is a rich mechanism that does not require access to system tables. Use a batch to execute a set of SQL statements. Use procedures to use a set of SQL statements more than once. Procedures allow you to save a set of SQL statements whereas batches are temporary in nature. Slide 7 Installing Windows XP Professional Using Attended Installation Slide 7 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 4 Can you write SQL Server 2005 stored procedures without the knowledge of any T-SQL statements? The belief that the SQL Server 2005 stored procedures can be written without the knowledge of T-SQL statements is partially true. While it is technically possible to create a stored procedure without using T-SQL, it is not possible to access any data without using T-SQL statements. FAQs ¤NIIT Instructor Inputs 4.7 Slide 8 Installing Windows XP Professional Using Attended Installation Slide 8 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 4 Can a view contain a CASE statement? Yes, you can use a CASE statement in a view, but you have to create the view by using Query Analyzer and not SQL Server Enterprise Manager. There is a limitation in creating views in Enterprise Manager when the view contains a CASE statement. FAQs (Contd.) Slide 9 Installing Windows XP Professional Using Attended Installation Slide 9 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 4 Can you use the FREETEXT predicate in a programming language with a SELECT statement? Yes, the FREETEXT predicate can be used in a programming language with a SELECT statement in the same way as it is used in SQL Server. FAQs (Contd.) 4.8 Instructor Inputs ¤NIIT Slide 10 Installing Windows XP Professional Using Attended Installation Slide 10 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 4 Is it must to create a unique index on a table before creating a full-text index on it? Yes, it is must to create a unique index on a table before creating a full-text index on it. FAQs (Contd.) Slide 11 Installing Windows XP Professional Using Attended Installation Slide 11 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 4 Can you create more that one full-text index on a table? Yes, you can create more than one full-text index on table on different columns. When you use the different full-text predicates with the SELECT statement, the suitable full-text index is automatically selected.
