The INSERT INTO Statement

The INSERT INTO statement is used to insert new rows into a table.

The syntax of inserting data into a table is given on the right: 
 INSERT INTO  table_name
   VALUES (value1, value2,....)
 

 SQL> insert into  Persons 
   2    values ('Hansen', 'Ola', 'Timoteivn 10', 'Sandnes');

 1 row created.

 SQL> insert into  Persons
   2    values ('Svendson', 'Tove', 'Borgvn 23', 'Sandnes');

 1 row created.

 SQL> insert into  Persons
   2    values ('Pettersen', 'Kari', 'Storgt 20', 'Stavanger');

 1 row created.

You can also specify the columns for which you want to insert data: 
 INSERT INTO
   table_name (column1, column2, ...)
   VALUES (value1, value2, ....)
 

 SQL> insert into  Persons  (LastName, Address)  
   2    values ('Rasmussen', 'Storgt 67');

The columns not specified are inserted with values NULL.
