CS 5483 Data Warehousing and Data MiningExercise 1: Database Practice: Microsoft SQL Server

Accessing MS SQL Server1. Login Windows XP by entering your CS LAB account and password2. Click Start => All Programs and select Microsoft SQL Server

3. Click the Query Analyzer item4. Under Connect to SQL Server window, under SQL Server: type / select w2ksc from the

browse button, under Use SQL Server Authentication, Login name: text box, type your

group number, for example grp## (## is your group number, e.g. grp01), under Password

text box, type abc123, click the OK button to connect to the server

5. Under the grp##_db Database, type different commands within the query area, then the result

will be shown in Result area.6. If you want to change your password, you may type this statement in Query area:

sp_password old_password, new_password

For example sp_password 'abc123', 'new123'

Click the Play button

Reminder:

You have the sole responsibility of keeping and remembering your new password

After every execution of the statements, you should clear the previous statement(s)

7. Type then execute the following statement:

create table course

(

course_no integer not null,

primary key(course_no)

)

8. Type then execute the statement

create table person

(

id_no integer not null,

name varchar(50),

birth_date datetime,height float,

weight float,

primary key(id_no)

)

9. Type then execute

create table student(


student_id integer not null,

dept_name varchar(100),

course_taken integer,

primary key(id_no)

)

create table students_registered

(course_no integer not null,


primary key (course_no, id_no),

foreign key (course_no) references course(course_no),

foreign key (id_no) references student(id_no)

)


insert into person (id_no, name, birth_date, height, weight)

values (1, 'John Doe', 'mar 1, 1997 0:0:0.0', 1.11, 1.11)



values (2, 'Able Chitson', 'mar 2, 1997', 2.22, 2.22)

System TablesIn schema translation design, the database schema from source database is extracted using MS SQL server's

system tables. System tables are tables used to store information about the system (the database catalog) or

an individual database (the database catalog). MS SQL Server system tables used by our schema translation

are shown in following table. Metadata of source database is extracted from system tables.

Important System Tables used in ProjectTables Name Function

syscolumns Contains one row for every column in every table and view, and a row for each

parameter in a stored procedure.

sysindexes Contains one row for each each clustered index and one row for each nonclustered index.

These indexes are the result of a CREAT INDEX statement or the CREATE TABLE

statement with a PRIMARY KEY or UNIQUE constraint. Additionally, sysindexes

contains one row for each table that has no clustered index and one row for each table

that contains text or image columns.

sysobjects Contains one row for each each database object and temporary object.

sysreferences Contains one row for each FOREIGN KEY constraint.

Sample SQL StatementsGet table information

To create a tables, we should look at the tables syscolumns , systypes , syscomments and sysobjects. These

tables contains the tables name, column name, column type, column length, default value, null value and

identity. This SQL statement is order by the object ID and the Column ID (syscolumns.colid). cold is

the order of the columns in a table. The first column in a table is 1 and the second is 2 and so on.
