You might have a table with some information and you want to copy the data of a few columns to another table. First thing you need to do is to create a table with columns same to the specific columns you require from original table.
Let say you have a table table1 with following fields:
name, email, company
You want to copy all the names and emails to a new table. So you will create a new table let say table2 with fields:
Following query will copy all the names and emails from table1 to table2
INSERT INTO`table2`(name, email) SELECT name, email FROM `table1`
You can also copy filtered records using where clause like
INSERT INTO `table2`(name, email ) SELECT name, email FROM` table1` WHERE company='Google'
