EXERCISE: 2(a)

DATE:25.09.2012 DATA MANIPULATION

AIM:

To create the data manipulation for

(a)Insert

Delete

Update

ALGORITHM:

Step 1:Start the program.

Step 2:Tables are crated and the values are inserted to table .

Step 3:Constrains was added to the field ticket no to the table.

Step 4:New column is added to the table and the table is displayed.

Step 5:Stop the program.

CODING:

The INSERT INTO statement

The INSERT INTO statement is used to insert a new row in a table.

SQL INSERT INTO Syntax

It is possible to write the INSERT INTO statement into two forms.

The first form doesnt specify the column names where the data will be

inserted only their values.

SYNTAX:

INSERT INTO table_nameVALUES(value1,value2,value3,);


14/93

14

SQL INSERT INTO Example

SQL> INSERT INTO persons VALUES (5,kalai,akkash,rome 2,jeniva);

RESULT:

1 row created.

The DELETE Statement

The delete statement is used to delete rows in a table.

SQL DELETE syntax

Delete from table_name

Where some_column=some_value

EXAMPLE:

SQL>delete from persons Where last name =lkalai and first name=aakash;

RESULT:

1 row deleted.

EXAMPLE:

SQL>select * from pesons;

OUTPUT:

P_ID LASTE NAME FIRST NAME ADDRESSS CITY

2 Swenson Tove Brogan 23 Sandnes

3 Petersen Kari Storgt 20 Stavenger

5 Tjessem Jakob

DELETE All Rows

It is possible to delete all rows in a table without deleting the table. This means that the able

structure, attributes, and indexes will be intact.


15/93

SYNTAX:

Delete from table_name;

Or

Delete * from table_name;

EXAMPLE:

SQL>select * from discounts;

RESULT:

No rows selected.

The UPDATE statement

The update statement is used to update the existing records in a table.

SQL UPDATE Syntax

Update table_nameSet column1=value, column2=value2, Where come_column=some_value;

The where clause specified which record or records that should be updated. If you omit the where

clauses ,all records will be updated.

SQL UPDATE with WHERE clause example

EXAMPLE:

SQL>select * from persons;
