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. It is better to have smaller stored procedure calls than one very large stored procedure because it makes maintaining the code easier.  Return values from stored procedures: Ensure that all stored procedures return a value indicating their status. This will help evaluate their success or failure status.  Use the UNION ALL operator to combine the records of two tables: While creating a view if the records are combined from multiple tables having different number of columns, you should use the UNION ALL operator. Ensure that the output of both the SELECT statements involved in the UNION ALL operator has the same number of columns.  Refresh the views when updating the table: When performing any operation on a table, such as inserting columns in a table, keep refreshing the dependent views. For example, suppose you are adding a new column to a table that is being referenced by a view. In such a situation, the new column will not automatically be reflected to the view, especially if the view is performing a SELECT * from the table. For the new column to be reflected on the view, you have to refresh the definition of the view by using the sp_refreshview system stored procedure. From the Expert’s Des k Best Practices ¤NIIT Querying, Managing, and Administering Databases Using SQL Server 2005 4.5 The following tips and tricks will help you use views, batches, stored procedures, and functions in SQL Server 2005:  Use SET_NOCOUNT_ON at the beginning of SQL batches, stored procedures, and triggers. This will increase the performance by reducing network traffic. Setting SET_NOCOUNT_ON suppresses the messages regarding how many rows are affected after executing the INSERT, UPDATE, SELECT and DELETE statements.  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 routine_name The preceding code sample will allow you to search the stored procedures defined in the SQL Server, which contains some specific keyword such as INDEX, TRIGGER or UPDATE.  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.  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.  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. Tips and Tricks FAQs 4.6 Querying, Managing, and Administering Databases Using SQL Server 2005 ¤NIIT  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.  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.  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. ¤NIIT Querying, Managing, and Administering Databases Using SQL Server 2005 4.7 1.
