You can insert records in a table using data that are already stored in the database. This is only a copy of data and it doesn’t affect the origin table.

The INSERT INTO SELECT statement combines INSERT INTO and SELECT statements and you can use any conditions you want. The syntax is:

INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1, column2, column3, ...
FROM table1
WHERE condition;

Here is an example that inserts in the table Person all the male students from the table Students.

INSERT INTO Person(Id, Name, DateOfBirth, Gender)
SELECT Id, Name, DateOfBirth, Gender
FROM Students
WHERE Gender = ‘M’
