Outline Materi• Insert• Update• Delete• PreparedStatement

Insert• Memasukan data pada table di database

• Sintak SQL :– Untuk insert ke semua field dalam 1 record:

insert into tableName values (value1, value2, …, valueN)

– Untuk insert ke beberapa field dalam 1 record :insert into tableName (column1, cloumn2, …, columnN) values (value1, value2, …, valueN)

Contoh :insert into Enrollment values (‘0800755660’, ‘CS001’,’8/14/2009’,’A’)

insert into Enrollment (binusianId, courseId, grade) values (‘0800755660’, ‘CS001’,’A’)

binusianId courseId dataRegisted grade

1100755660 CS001 8/14/2009 A

binusianId courseId dataRegisted grade

1100755660 CS001 A

Update• Mengubah data pada table di database

• Sintak SQL :Update tableName set column1= newValue1, column2 =newNalue2 , …, columnN = newValueN where [condition]

Jika tidak menggunakan where condition maka akan mengupdate 1 table tersebut.

Contoh :

Data sebelumnya :

Update grade-nya menjadi B untuk binusian id : 1100755660 dan course id : cs001

update Enrollment set grade =‘B’ where binusianId =‘1100755660’ and courseId = ‘CS001’

binusianId courseId dataRegisted grade

1100755660 CS001 8/14/2009 A

1100755660 CS002 8/14/2009 B

1100755660 CS003 8/14/2009 C

binusianId courseId dataRegisted grade

1100755660 CS001 8/14/2009 B

1100755660 CS002 8/14/2009 B

1100755660 CS003 8/14/2009 C

Delete• Mengubah data pada table di database

• Sintak SQL :delete from tableName where [condition]

Contoh :

Data sebelumnya :

Delete data untuk binusian id : 1100755660 dan course id : cs001

delete Enrollment where binusianId =‘1100755660’ and courseId = ‘CS001’

binusianId courseId dataRegisted grade

1100755660 CS001 8/14/2009 A

1100755660 CS002 8/14/2009 B

1100755660 CS003 8/14/2009 C

binusianId courseId dataRegisted grade

1100755660 CS002 8/14/2009 B

1100755660 CS003 8/14/2009 C
