SQL INSERT INTO Statement

The INSERT INTO statement is used to insert new records in a table Or  to insert a new row in a table.

SQL INSERT INTO Syntax

It is possible to write the INSERT INTO statement in two forms.
The first form doesn't specify the column names where the data will be inserted, only their values:

INSERT INTO table_name  VALUES (value1, value2, value3,...)

The second form specifies both the column names and the values to be inserted:

INSERT INTO  table_name (column1, column2, column3,...) VALUES (value1, value2, value3,...)

SQL INSERT INTO Example

We have the following "Persons" table:

P_Id	LastName	FirstName	Address	City
1	Suhail	Osmani	Maharaj Nagar	Sitapur
2	Maxwel	Tom	Biswan	Sitapur
3	Rahi	Ayon	Okhla	Delhi

Now we want to insert a new row in “Persons” TABLE.
We use the following SQL statement:

INSERT INTO Persons  VALUES (4,'Nyla', 'Johan', 'Bakken 2', 'Delhi')

“Persons” TABLE will now look like this:

P_Id	LastName	FirstName	Address	City
1	Suhail	Osmani	Maharaj Nagar	Sitapur
2	Maxwel	Tom	Biswan	Sitapur
3	Rahi	Ayon	Okhla	Delhi
4	Nyla	Johan	Bakken 2	Delhi

Insert Data Only in Specified Columns

It is also possible to only add data in specific columns.
The following SQL statement will add a new row, but only add data in the "P_Id", "LastName" and the "FirstName" columns:

INSERT INTO Persons (P_Id, LastName, FirstName) VALUES (5, 'Thoria', 'Jakob')

“Persons” TABLE will now look like this:

P_Id	LastName	FirstName	Address	City
1	Suhail	Osmani	Maharaj Nagar	Sitapur
2	Maxwel	Tom	Biswan	Sitapur
3	Rahi	Ayon	Okhla	Delhi
4	Nyla	Johan	Bakken 2	Delhi
5	Thoria	Jakob
