Course Outline
What is a database
A database is information that is set up for easy access, management and updating. Computer databases typically store aggregations of data records or files that contain information, such as sales transactions, customer data, financials and product information. Databases are used for storing, maintaining and accessing any sort of data. They collect information on people, places or things. That information is gathered in one place so that it can be observed and analyzed. Databases can be thought of as an organized collection of information.
Variables
SQL Variables are used to store and manipulate data within SQL code. They are assigned a value that can be used throughout the SQL statement or batch. Variables are typically declared using the DECLARE statement and can be assigned values using the SET statement.
Data Types and Constraints
SQL data types define the type of data that can be stored in a database table column, such as integer, string, or date. Constraints are rules that are applied to a database table to enforce data integrity, such as primary keys, foreign keys, unique constraints, and check constraints. They help ensure that data is accurate and consistent.
Table
In SQL, a table is a collection of data that is organized into rows and columns. Each row represents a record in the table, and each column represents a specific attribute or field of the data. Tables can be created using the CREATE TABLE statement and can be modified using the ALTER TABLE statement. Tables are a fundamental component of relational databases and are essential for organizing and storing large amounts of data.
Queries and Index
SQL queries are used to retrieve data from one or more tables in a relational database. They typically use the SELECT statement to specify which columns and records to retrieve, and may also include filtering, sorting, grouping, and joining operations. An index is a data structure that improves the performance of queries by providing a quick lookup of data based on specific columns. Indexes can be created using the CREATE INDEX statement and can significantly improve the speed and efficiency of SQL queries.
Clause
In SQL, a clause is a component of a SQL statement that specifies additional information or conditions for the query. Common SQL clauses include WHERE, GROUP BY, HAVING, and ORDER BY, which are used to filter, group, aggregate, and sort data in various ways.
Control Flow Structure
Control flow structures in SQL are used to conditionally execute code based on certain conditions. Common SQL control flow statements include IF-ELSE, CASE, and WHILE. These statements allow developers to add branching logic and perform conditional operations based on the data retrieved from the database.
Join
SQL join is a way of combining two or more tables in a relational database by matching rows based on a common column. There are different types of joins such as inner join, left join, right join and full outer join. SQL join is used to retrieve related data from multiple tables in a single query.
Conditions
In SQL, conditions are used to filter data based on specific criteria. Conditions are typically included in the WHERE clause of a SQL query and use comparison operators such as =, <, >, and LIKE to specify the condition. Conditions allow developers to retrieve specific data from a database based on certain requirements.
Aggregate Functions
SQL aggregate functions are used to perform calculations on sets of data in a database. These functions include SUM, AVG, COUNT, MAX, and MIN, and can be used to perform various calculations on numerical or non-numerical data. Aggregate functions are often used in conjunction with GROUP BY clauses to summarize and aggregate data in a meaningful way.
