SQL | W3Skul | Konten SQL

 

Sintaks SQL


Tabel Database

Database paling sering berisi satu atau beberapa tabel. Setiap tabel diidentifikasi dengan nama (misalnya "Pelanggan" atau "Pesanan"). Tabel berisi rekaman (baris) dengan data.

Dalam tutorial ini kita akan menggunakan database sampel Northwind yang terkenal (termasuk dalam MS Access dan MS SQL Server).

Di bawah ini adalah pilihan dari tabel "Pelanggan":

CustomerIDCustomerNameContactNameAddressCityPostalCodeCountry
1

Alfreds FutterkisteMaria AndersObere Str. 57Berlin12209Germany
2Ana Trujillo Emparedados y heladosAna TrujilloAvda. de la Constitución 2222México D.F.05021Mexico
3Antonio Moreno TaqueríaAntonio MorenoMataderos 2312México D.F.05023Mexico
4

Around the HornThomas Hardy120 Hanover Sq.LondonWA1 1DPUK
5Berglunds snabbköpChristina BerglundBerguvsvägen 8LuleåS-958 22Sweden

Tabel di atas berisi lima catatan (satu untuk setiap pelanggan) dan tujuh kolom (CustomerID, CustomerName, ContactName, Address, City, PostalCode, dan Country).


Pernyataan SQL

Sebagian besar tindakan yang perlu Anda lakukan pada database dilakukan dengan pernyataan SQL.

Pernyataan SQL berikut memilih semua rekaman dalam tabel "Pelanggan":

Contoh

SELECT * FROM Customers;
Cobalah sendiri »

Dalam tutorial ini kami akan mengajari Anda semua tentang pernyataan SQL yang berbeda.


IKLAN

Keep in Mind That...

  • SQL keywords are NOT case sensitive: is the same as select SELECT

In this tutorial we will write all SQL keywords in upper-case.


Semicolon after SQL Statements?

Some database systems require a semicolon at the end of each SQL statement.

Semicolon is the standard way to separate each SQL statement in database systems that allow more than one SQL statement to be executed in the same call to the server.

In this tutorial, we will use semicolon at the end of each SQL statement.


Some of The Most Important SQL Commands

  • SELECT - extracts data from a database
  • UPDATE - updates data in a database
  • DELETE - deletes data from a database
  • INSERT INTO - inserts new data into a database
  • CREATE DATABASE - creates a new database
  • ALTER DATABASE - modifies a database
  • CREATE TABLE - creates a new table
  • ALTER TABLE - modifies a table
  • DROP TABLE - deletes a table
  • CREATE INDEX - creates an index (search key)
  • DROP INDEX - deletes an index
