Let’s assume that, we have our employee table.
We have to copy this data
into another table. For this purpose,
we can use the INSERT INTO SELECT
operator. Before we go ahead and do that,
we would have to create another
table that would have the same structure
as the given table.
• First create the second table with
the same table structure with copied one.
• Then use the syntax:
Let’s say employee_duplicate is New table
employee is First table that we want to copy it into new table
INSERT INTO employee_duplicate SELECT * FROM employee;copy data from one table column to another table column in sql
#to copy or update a table column from another table column
UPDATE table_name1
SET column1 = (
SELECT column2
FROM table_name2
WHERE table_name1.id = table_name2.id
