A single table query is one that is relative to a multiple table query and refers to querying data from a datasheet. 4.2.1 Query all records In the command edit area, perform the input "select * from Scott.emp" and click the Execute button to appear with all the records in the EMP datasheet as shown in Figure 4.3.

In most cases, upgrading your database to SQL Server 2008 can improve query performance. However, if you have mission-critical queries that have been carefully optimized for performance, it is a good idea to create a planning guide for each query before you upgrade to keep the query plans for those queries. If, after t

from t where num between 1 and 3 6. The following query will also result in a full table scan: Select ID from t where name like '%abc% ' To improve efficiency, you can consider Full-text search. 7. The use of parameters in the WHERE clause also results in a full table scan. Because SQL resolves local variables only at run time, the optimizer cannot access the sched
