Question

What are Joins in SQL Server and how we can implement them?

Shivanand Arur · Answer

Joins are basically used when you want combined information from more than 1 table. The syntax used to join tables and get the information is like this.... Lets say that we have 2 tables "Employee" and "Departments" "Employee" table contains 3 columns Table Name: Employee Table Name: Department EmpID Name Profile DeptID DeptName deptCity Profile 01 Shiv S/w Eng 001 IT Chennai S/w Eng 02 Anand Manager 002 Purchase Mumbai Manager 03 Aahan Manager 003 HR Mumbai Manager Now if you want to get information about the Employee and the Departname in which they work, you can get it through Joins... "Select Emp.Name, Emp.Profile, Dept.deptCity from Employee Emp, Department Dept JOIN Department Dept ON EMP.Profile = Dept.Profile". This was just a sample example to explain you. There are various types of JOINS which are as follows: 1. Inner Join: (Refer this site) http://www.1keydata.com/sql/inner-join.html 2. Outer Join: (Refer this site) http://www.1keydata.com/sql/sqlouterjoin.html 3. Left Outer Join: (Refer this site) http://www.1keydata.com/sql/left-outer-join.html 4. Cross Join: (Refer this site) http://www.1keydata.com/sql/cross-join.html HOPE this helps you!!! PLEASE MARK THE ANSWER AS ACCEPTED IF IT HELPED
