    INSERT INTO SELECT statement:

    INSERT INTO SELECT statement is used to copy data from existing table into another table.

    Syntax-1:

    INSERT INTO tablename2 SELECT * FROM tablename1;

    Syntax-2 

    INSERT INTO tablename2 (columnname(s)) SELECT columnname(s) FROM tablename1;

    Example:

    INSERT INTO Employee (Name, City) SELECT StudentName, City FROM School;

    This query will insert studentname and his respective city into Employee table from School table.
