History of SQL

  • SQL (Structured Query Language) was developed by IBM in the late 1970s for IBM's DB2 RDBMS
  • SQL became the language for relational database development
  • ANSI formalized SQL as a standard in 1986
  • SQL is vital to developing databases in major platforms such as Oracle, MySQL and Microsoft SQL Server

SQL Is Three Languages

  • SQL is actually three languages!
  • Data Definition Language (DDL) for the creation, alteration and dropping of database objects (e.g., tables)
  • Data Manipulation Language (DML) for querying and updating relational data
  • Data Control Language (DCL) for securing data

Sample Uses of SQL

  • Interactive through GUI interfaces such as Microsoft Access query grids
  • Embedded in GUI and console business applications
  • Embedded in Java EE and Microsoft .NET web applications

SQL Difficulty Level

  • SQL is a high-level data access language
  • SQL was designed to be written by end users and developers
  • SQL is not a programming language
  • Commonly used in programming courses

Learning SQL

  • SQL is relatively straightforward to learn
  • Design query grids such as offered by Microsoft Access expedite learning SQL
  • Excellent documentation is available from all major vendors such as MySQL: https://dev.mysql.com/doc/refman/5.7/en/
  • SQL lexicon consists of understandable commands such as SELECT, INSERT, UPDATE and DELETE

SQL: The Good

  • Relatively straightforward to learn
  • Cross-platform
  • Excellent documentation from major vendors (e.g., Oracle, IBM, Microsoft)
  • Well respected in the IT industry

SQL: The Bad

  • SQL is a computer language and may present challenges to students with no computer language background.

SQL: The Future

  • SQL has a bright future!
  • Both ANSI and ISO publish standards for SQL usage
  • Tremendous corporate investment in SQL-based applications
  • Full support by major vendors such as Oracle, Microsoft and IBM

Syntax

  • Syntax was originally established by IBM based on the company's PL/I programming language
  • The language keywords are not case sensitive although capitalization is standard practice
  • The syntax is based on easily-understandable verbs:
    • SELECT
    • INSERT
    • UPDATE
    • DELETE

Creating a Table

CREATE TABLE GardenTools
(
id			INT NOT NULL,
description	VARCHAR(1000),
price			NUMERIC (9,2))

Comments

--Single-line comments follow 2 hyphens

/*
This is a 
	multi-line comment.
*/

Strings

  • Fixed-length strings are defined as char:
    • Customer_name CHAR(25) DEFAULT 'BestCo Ltd.'
  • Varying-length strings are defined as varchar:
    • Address_line VARCHAR(100) DEFAULT '2017 Anywhere Lane'

Integer, Decimal, and Float Column Types

  • quantity_on_hand INT DEFAULT 0
  • item_price DECIMAL(9,2)
  • population_of_asia FLOAT

Date and Time Column Types

  • date_of_order DATE
  • time_of_order TIME

Selecting Data from a Table

  • SELECT * FROM GardenTools
  • SELECT id, description FROM GardenTools WHERE price > 9.99

Inserting a Row into a Table

  • INSERT INTO GardenTools VALUES (202, 'Large rake', 24.49)
  • INSERT INTO GardenTools (id, description) VALUES (219, 'Small rake')

Updating a Row in a Table

  • UPDATE GardenTools
  • SET price = 25.99
  • WHERE id = 202

Deleting a Row in a Table

  • DELETE FROM GardenTools WHERE id = 202
