all about joins in database management systems
and database programing using the SQL hope you get good information about joins
so this is also used by web developers as syntax to fetch information in the database
SQL JOINS allow data to be combined from multiple tables by performing joins between columns that share common values. There are five main types of joins: equi joins which combine rows where joined columns are equal, inner joins which return rows where there is a match in both tables, outer joins which return all rows of the left or right table even if there is no match, self joins which join a table to itself, and non-equi joins which join on columns that are not equal. Joins are useful for combining related data across tables and are implemented using conditions in the WHERE clause that compare columns from different tables.
This document discusses different types of SQL joins. It defines SQL joins as using the JOIN keyword to query data from two or more related tables based on relationships between columns. It describes inner, left, right, and full joins. Inner joins return rows when there is a match in both tables. Left joins return all rows from the left table even without matches in the right table. Right joins are the opposite of left joins. Full joins return rows when there is a match in either table. Examples are provided to illustrate each type of join.
This document discusses different types of joins in SQL, including inner joins, outer joins, cross joins, and natural joins. It provides examples of how to write join conditions in the WHERE clause and use table aliases. It also covers Cartesian products that result when join conditions are omitted, as well as guidelines for qualifying ambiguous column names when joins involve multiple tables.
This document discusses different types of SQL joins, including inner joins, outer joins, equi joins, non-equi joins, natural joins, and self joins. It provides examples of how to write queries using each type of join, explaining the purpose and output of each. Key points covered include that equi joins use equality comparisons, natural joins only show common columns once, and self joins allow a table to be joined to itself.
SQL is a programming language used to communicate with and manipulate databases. It allows users to retrieve, insert, update and delete data from databases. Common SQL statements include JOINs, which combine data from two or more tables based on a common column. Some types of JOINs are INNER JOIN, which returns rows with matches in both tables; LEFT JOIN, which returns all rows from the left table; and FULL JOIN, which returns rows that match in either table. JOINs are often used with SELECT statements to query multiple tables at once.
This document discusses different types of joins in SQL, including inner joins, outer joins, cross joins, and natural joins. It provides guidelines for writing join conditions, handling ambiguous column names, and joining more than two tables.

Join queries combine data from two or more tables in a database. An inner join returns rows where there is a match between columns in both tables. A left join returns all rows from the left table, along with matched rows from the right table, returning null if there is no match. A right join is similar but returns all rows from the right table. A full join returns all rows and fills in nulls for missing matches between the tables.
This document discusses different types of joins in SQL including inner joins, self joins, outer joins, and cross joins. An inner join combines rows from two tables based on a common column and returns matched rows. A self join performs an inner join on a single table to match rows with itself. Outer joins return all rows from one or both tables whether or not they have a match. A cross join returns the Cartesian product of all rows in two tables.
Joins in databases combine records from two or more tables. The main types of joins are natural joins, equijoins, self joins, and outer joins. Natural joins automatically match columns with the same name, while equijoins use equality comparisons in the WHERE clause. Self joins match a table to itself, and outer joins return all records from one or both tables even if there are no matches.
SQL JOINS combine data from two or more tables by matching column values. The major JOIN types are INNER, LEFT OUTER, RIGHT OUTER, and FULL OUTER JOINS which return matched and unmatched rows based on criteria. JOINS improve performance over subqueries and are used with other SQL clauses like WHERE, GROUP BY, and aggregate functions.

This document provides an overview of MySQL JOIN and UNION operations. It discusses subqueries, table aliases, multi-table joins, UNION ALL, UNION rules, and GROUP BY. Subqueries allow querying data from multiple tables in a nested format. Table aliases are used to temporarily rename tables and columns for readability. JOIN operations combine data from two or more tables, including INNER JOIN, LEFT JOIN, and RIGHT JOIN. UNION combines the results of multiple SELECT statements, requiring the same number and order of columns. UNION rules specify that data types must be compatible. GROUP BY is used to retrieve aggregate information about grouped data.
This document provides an overview of key concepts for getting started with Microsoft Excel 2013, including understanding spreadsheets and Excel windows, entering labels and values, using formulas, editing cells, switching views, and setting print options. The objectives are to learn how to identify Excel window components, enter and edit simple formulas, switch between worksheet views, and choose print layout and settings.
The SQL UNION operator combines the results of two or more queries into a single result set. By default, UNION eliminates duplicate rows but UNION ALL includes duplicate rows. For UNION, the number and order of columns must match between queries and column data types must be compatible. Usually the column names from the first query are used. Examples demonstrate UNION, UNION ALL, and combining queries on the same table or with joins between tables.
This document discusses different types of SQL joins: inner join, outer join, and cross join. It explains that inner joins return only matching records from both tables, while outer joins return all records from one table and matching records from the other table.

A JOIN is a means for combining fields from two tables by
using values common to each
• SQL joins are used to combine rows from two or more
tables.
OR
• An SQL JOIN clause is used to combine rows from two or
more tables, based on a common field between them.
3. Type of SQL JOINs
• INNER JOIN: Returns all rows when there is at least one match in
BOTH tables
• LEFT JOIN: Return all rows from the left table, and the matched
rows from the right table
• RIGHT JOIN: Return all rows from the right table, and the matched
rows from the left table
• FULL JOIN: Return all rows when there is a match in ONE of the
tables
• SELF JOIN: Returns table to itself as if the table were two tables;
temporarily renaming at least one table in the SQL statement.
• CARTESIAN JOIN: Returns the Cartesian product of the sets of
records from two or more joined tables
4. SQL INNER JOIN
• The INNER JOIN keyword selects all rows from
both tables as long as there is a match between
the columns in both tables.
• SQL INNER JOIN Syntax
• SELECT column_name(s)
FROM table1
INNER JOIN table2
ON table1.column_name=table2.column_name;
• Lets look at the tables on the preceding slides
6. SQL INNER JOIN
The relationship between the two tables above is the "CustomerID"
column.
• Then, if we run the following SQL statement (that contains an INNER
JOIN):
Example
SELECT
Customers.CustomerID,
Customers.CustomerName,
Customers.ContactName,
Customers.district,
Orders.OrderID,
Orders.OrderDate
FROM Customers
INNER JOIN Orders
ON Customers.CustomerID=Orders.CustomerID;
7. SQL INNER JOIN
• Output would be
CustomerID CustomerName ContactName district OrderID OrderDate
1 Olumonde Godie wakiso 101 2019-03-18
2 Gamukama Raymond luwero 102 2019-03-19
3 Nabacwa Milica kampala 103 2019-03-20
Note: (It selects all rows from both tables as long
as there is a match between the columns in both
tables)
.
8. SQL LEFT JOIN Keyword
• The LEFT JOIN keyword returns all rows from the left
table (table1), with the matching rows in the right table
(table2). The result is NULL in the right side when there
is no match.
SQL LEFT JOIN Syntax
• SELECT column_name(s)
FROM table1
LEFT OUTER JOIN table2
ON table1.column_name=table2.column_name;
• In some databases LEFT OUTER JOIN is called LEFT
JOIN.
9. Using our tables above,
The following SQL statement will return all customers, and
any orders they might have:
SELECT
Customers.CustomerID,
Customers.CustomerName,
Customers.ContactName,
Customers.district,
Orders.OrderID,
Orders.OrderDate
FROM Customers
LEFT JOIN Orders
ON Customers.CustomerID=Orders.CustomerID;
10. SQL LEFT JOIN Example
Note: The LEFT JOIN keyword returns all the rows from the left table
(Customers), even if there are no matches in the right table (Orders).
CustomerID CustomerName ContactName district OrderID OrderDate
1 Olumonde Godie wakiso 101 3/18/2019
2 Gamukama Raymond luwero 102 3/19/2019
3 Nabacwa Milica kampala 103 3/20/2019
4 Kahinda Adon null null null
11. SQL RIGHT JOIN Keyword
• The RIGHT JOIN keyword returns all rows from the
right table (table2), with the matching rows in the left
table (table1). The result is NULL in the left side when
there is no match.
• SQL RIGHT JOIN Syntax
SELECT column_name(s)
FROM table1
RIGHT OUTER JOIN table2
ON table1.column_name=table2.column_name;
NB:In some databases RIGHT OUTER JOIN is called
RIGHT JOIN.
12. Using our tables above,
The following SQL statement will return all employees, and
any orders they have placed:
SELECT
Customers.CustomerID,
Customers.CustomerName,
Customers.ContactName,
Customers.district,
Orders.OrderID,
Orders.OrderDate
FROM Customers
RIGHT JOIN Orders
ON Customers.CustomerID=Orders.CustomerID;
13. SQL RIGHT JOIN Example
• Note: The RIGHT JOIN keyword returns all the rows from the right table
(Employees), even if there are no matches in the left table (Orders).
CustomerID CustomerName ContactName district OrderID OrderDate

3 Nabacwa Milica kampala 103 3/20/2019
null null null null 104 3/21/2019
14. SQL FULL OUTER JOIN Keyword
• The FULL OUTER JOIN keyword returns all rows
from the left table (table1) and from the right table
(table2).
• To achieve that, we use the join keyword
• The JOIN keyword combines the result of both LEFT
and RIGHT joins.
SQL FULL OUTER JOIN Syntax
SELECT column_name(s)
FROM table1
JOIN table2
ON table1.column_name=table2.column_name;
15. SQL FULL OUTER JOIN Example
• Using our tables above,
• The following SQL statement selects all customers, and all orders:
SELECT
Customers.CustomerID,
Customers.CustomerName,
Customers.ContactName,
Customers.district,
Orders.OrderID,
Orders.OrderDate
FROM Customers
RIGHT JOIN Orders
ON Customers.CustomerID=Orders.CustomerID;
16. Note: The JOIN keyword returns all the rows from the left table (Customers), and all the rows from the
right table (Orders). If there are rows in "Customers" that do not have matches in "Orders", or if there are
rows in "Orders" that do not have matches in "Customers", those rows will be listed as well.
CustomerID CustomerName ContactName district OrderID OrderDate

17. SELF JOIN
• is used to join a table to itself as if the table were two
tables; temporarily renaming at least one table in the SQL
statement.
SELECT a.column_name, b.column_name...
FROM table1 a, table1 b
WHERE a.common_field = b.common_field;
Here, the WHERE clause could be any given expression
based on your requirement, for example.(a.value>b.value)
18. CARTESIAN JOIN
• it returns the Cartesian product of the sets of records from
two or more joined tables. Thus, it equates to an inner join
where the join-condition always evaluates to either True
or where the join-condition is absent from the statement.
SELECT table1.column1, table2.column2...
FROM table1, table2 ;
