Join in
SQL Sever
When
we need to select data from more than one table then we can use joins in SQL
Server. We can join two or more tables on the basis of common column between
these tables.
Consider
the following table which I am using in this example:-
Table 1:- Emp_Record
create table Emp_Record(eid int primary key, ename varchar(100), email varchar(100))
Figure

Table 2:-emp_sal
create table emp_sal(eid int foreign key references emp_record(eid), salary int, ispermanent varchar(100))

Types of
Joins
Inner Join
When
we need to select the common data from more than one table then we will use
inner join. It will select only those data which will be common in these two tables.
