6. Features Of MS SQL Server
● Query Analyzer
● Profiler
● Service Manager
● Bulk Copy Program (BCP)
7. Query Analyzer
● Allows us to write queries and SQL statements
● Checks syntax of the SQL statement
written.
● Executes the statements
● Store and reload statements
● Save the results in file
● View reports (either as grid or as a text)

● Monitoring tool
● Used for performance tuning
● An event monitoring protocol
● Event may be a query or a
transaction like logins etc
9. Service Manager
● Helps us to manage services
● More than one instance of SQL server can be
installed in a machine
● First Instance is called as default instance
● Rest of the instances (16 max) are called as
named instances
● Service manager helps in starting or stopping
the instances individually
10. Bulk Copy Program (BCP)
● Bulk Copy Program
● A powerful command line utility
that enables us to transfer large
number of records from a file to
database
● Time taken for copying to and from
database is very less
● Helps in back up and restoration
11. Database operations
● Creating a database
Create database <dbname>
● Changing a database
Use <dbname>
● Dropping a database
Drop database <dbname>
12. SQL DDL and DML Statements
● Data Definition Language (DDL) Statements
○ CREATE TABLE – Create a new table
○ ALTER TABLE – Modify a table
○ DROP TABLE – Delete a already existing a table
○ RENAME TABLE – Rename a table
