PENGANTAR MY SQL
LABORATORIUM 4 – BASISDATA
Melihat dafar database di komputer :
RUMUS :
SHOW DATABASES;
HASIL :
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| webauth |
+--------------------+
Membuat database baru :
RUMUS :
CREATE DATABASE(spasi)NAMA_DATABASE;
CONTOH :
mysql> create database lab4;
Query OK, 1 row affected (0.09 sec)
Memakai database yang telah kita buat
RUMUS :
USE(spasi)NAMA_DATABASE;
CONTOH :
mysql> use lab4;
Database changed
Membuat tabel baru :
RUMUS :
CREATE TABLE NAMA_TABEL
(
Nama_Kolom1(spasi)tipe_data(ukuran),
Nama_Kolom2(spasi)tipe_data(ukuran),

2. [Type text] Page 2
Nama_Kolom3(spasi)tipe_data(ukuran),
Nama_Kolom4(spasi)tipe_data(ukuran));
CONTOH :
mysql> create table t_mhs(nim varchar(10), nama_mhs varchar(50),
alamat varchar(50), no_telp varchar(12));
Query OK, 0 rows affected (0.16 sec)
Melihat hasil tabel yang kita buat :
RUMUS :
DESC(spasi)NAMA_TABEL;
CONTOH :
mysql> desc t_mhs;
+----------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+-------------+------+-----+---------+-------+
| nim | varchar(10) | YES | | NULL | |
| nama_mhs | varchar(50) | YES | | NULL | |
| alamat | varchar(50) | YES | | NULL | |
| no_telp | varchar(12) | YES | | NULL | |
+----------+-------------+------+-----+---------+-------+
4 rows in set (0.08 sec)mysql> desc mahasiswa;
Input Data ke Dalam Tabel :
1. Menggunakan Rumus INSERT
2. Menggunakan Rumus LOAD DATA
1.Menginputkan data ke dalam tabel menggunakan perintah
INSERT
RUMUS :
Mysql >INSERT(spasi)INTO(spasi)NAMA_TABEL(spasi)VALUES
>(
>’DATA_KOLOM1’,

3. [Type text] Page 3
>’DATA_KOLOM2’,
>’DATA_KOLOM3’,
>’DATA_KOLOM4’
>);
CONTOH :
mysql> insert into t_mhs values( '111051005', 'Sholeh',
'Sleman','085785231478');
Query OK, 1 row affected (0.05 sec)
mysql> select *from t_mhs;
+-----------+----------+--------+--------------+

+-----------+----------+--------+--------------+
5 rows in set (0.00 sec)
2.Menginputkan data ke dalam tabel menggunakan perintah
LOAD DATA
Persiapkan file yang berisi data yang akan diinputkan ke tabel
di database kita, sesuai dengan urutan yg kita buat di MYSQL.
Simpan dengan format .txt
CONTOH : (dibuat di MS.EXEL dan disimpan dengan nama data.txt
= format TEXT(MS-DOS) )
111051001 Uning Jogja 085786452315
111051002 Yuli Bantul 081354687923
111051003 Wanto Sleman 088869874563
111051004 Catur Bantul 081244455566
RUMUS :
LOAD(spasi)DATA(spasi)LOCAL(spasi)INFILE(spasi)

Menghapus database dan tabel
Buat dulu table baru
mysql> create table mat_kul(id_matkul varchar(10), nama_matkul
varchar(50), sks int(1), semester int(1), dosen varchar(10));
Query OK, 0 rows affected (0.02 sec)
