Query Analyser , SQL Server Groups,
SQL Server Query Analyzer is a graphical user interface for
designing and testing Transact-SQL statements, batches,
and scripts interactively. It can be called from SQL Server
Enterprise Manager. You can merge data from SQL 2000
databases, AS/400 tables or other DBMS using Distributed
Microsoft SQL Server 2000 SQL Query Analyzer is a graphical
tool that allows you to:
Create queries and other SQL scripts and execute them
against SQL Server databases. (Query window)
Quickly create commonly used database objects from
predefined scripts. (Templates)
Locate objects within databases (object search feature), or
view and work with objects. (Object Browser)
Execute stored procedures without knowing the parameters.
(Object Browser procedure execution feature)
Debug stored procedures. (T-SQL Debugger)
Debug query performance problems. (Show Execution Plan)
Accessing Sql Query Analyzer
You can open Query Analyzer from Enterprise Manager by
clicking Tools > Query Analyzer.
Query Menu Items
The Query menu items are grouped into several sections
because they encompass different kinds of activities. .
Several items, such as changing database context and
parsing/executing queries, are also represented by default
Displaying the execution plan shows you how SQL Server
proposes to execute a specific query. There are usually a
number of different ways that the desired results of a query
can be achieved The execution plan shows you the decision
that SQL Server has made about how to run the query most
Select * from Users u, Departments d where u.DepartmentId= d.Id;
Tools Menu Items
The Tools menu contains three groupings, one for the
Object Browser and Object Search, one for managing
statistics and indexes, and one for setting options and
SQL Query Analyzer also has an "Object Browser" that
you can use to browse and edit tables, views, and stored
procedures. The Object Browser also displays a list of
common SQL Server functions and their parameters.
To open the Object Browser, press F8. Alternatively, you
can click the Object Browser icon on the toolbar.
Another way of showing the Object Browser is to goTools
> Object Browser > Show/hide. The Object Browser
displays to the left of your workspace.
You are now ready to write SQL queries against your
database. You can use this interface to create database
objects (such as databases, tables, views etc), insert data
into a database table, select data, update data, delete data.
The Edit Menu Items
The Edit menu items contain the usual commands for
cutting, copying, pasting, finding, and replacing text
strings. The Undo command will undo typing, one letter at
a time. All actions have keyboard shortcut keys assigned,
which are displayed in the right column of the menu list.
The Edit|Insert Template command displays a list of built-in
templates that ship with SQL Server 2000
Double-click the category you’re interested in to display a
list of individual templates.
Click Open when you’ve selected the desired template. This
displays the template file in the SQL pane of the Query
SQL Server Groups
You use SQL Server groups to organize sets of computers
running SQL Server. You can organize these groups by, say,
function or department. You can even create subgroups
within a group. In SQL Server Management Studio, you use
the Registered Servers view to work with server groups.
The top-level groups are already created for you, based on
the SQL Server instances.
Registering SQL Server Group
1.On the File menu, click New SQL Server Registration.
The Register SQL Server wizard is displayed.
3.In Available servers, type or select the name of the SQL
Server instance that you want to register, then click Add.
If you want to remove a SQL Server instance from the list,
in Added servers, select the name of the instance and click
4. When you have added all the instances that you want to
register to the Added servers list, click Next.
5.Select the authentication method, and for SQL Server
authentication enter the Login name and Password.
For SQL Server authentication, you can select the Prompt
for the SQL Server account information when connecting
check box. If you select this option, SQL Backup will not
connect to the SQL Server automatically; you will have to
connect manually by right-clicking on the SQL Server
instance in the servers pane, and clicking Connect. A dialog
box will then be displayed for you enter the authentication
6. Select the group to which you want to add the server.
9. SQL Backup registers the SQL Server instances. This
may take a few minutes.
To check the authentication details for a SQL Server, click
the SQL Server instance and then click Properties. You can
then enter the details and test them. Note that to change
the details for registration, you must re-enter the details in
the authentication page of the wizard.
Transact-SQL is central to the use of Microsoft SQL Server.
All applications that communicate with SQL Server do so by
sending Transact-SQL statements to the server, regardless
of an application's user interface.
A cursor is a pointer to a set of records returned by a SQL
statement. It enables you to take a set of records and deal
with it on a row-by-row basis.
Defining and Using Cursors
Step 1: Declare cursor:
To use a cursor you need to first declare it. This provides
definitions and characteristics of the record set for which
the cursor will be used.
Declare cursorname Cursor
For SQL statement
Ex: Declare ACustomer Cursor
For select * from customer where rating=‘a’
Step 2: Open cursor:
After declaring, cursor must be opened before it can be
used in your procedure or batch code.
Example: Open Acustomer
Step 3: Fetch data into variables:
This command is used to extract the data from the cursor.
FETCH Next From cursorname into list of local variables
Example: Fetch Next ACustomer into @CustID,
@CustName, @CustCity, @CustRating
Use @@Fetch_Status to test if record exist. If
@@Fetch_Status = 0, fetching is successful
Step 4: CLOSE cursorname
The CLOSE command is used to free the current result
set and locks.
Step 5: Deallocate cursor
DEALLOCATE command is used to remove the cursor
