This helped and it supports a BLOB/TEXT columns.

CREATE TEMPORARY TABLE temp_table
AS
SELECT * FROM source_table WHERE id=2;
UPDATE temp_table SET id=NULL WHERE id=2;
INSERT INTO source_table SELECT * FROM temp_table;
DROP TEMPORARY TABLE temp_table;
USE source_table;

Answer 3

insert into MyTable(field1, field2, id_backup)
    select field1, field2, uniqueId from MyTable where uniqueId = @Id;

Answer 4

A lot of great answers here. Below is a sample of the stored procedure that I wrote to accomplish this task for a Web App that I am developing:

-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON

-- Create Temporary Table
SELECT * INTO #tempTable FROM <YourTable> WHERE Id = Id

--To trigger the auto increment
UPDATE #tempTable SET Id = NULL 

--Update new data row in #tempTable here!

--Insert duplicate row with modified data back into your table
INSERT INTO <YourTable> SELECT * FROM #tempTable

-- Drop Temporary Table
DROP TABLE #tempTable

Answer 5

Say the table is user(id, user_name, user_email).

You can use this query:

INSERT INTO user (SELECT NULL,user_name, user_email FROM user WHERE id = 1)

Answer 6

Use INSERT ... SELECT:

insert into your_table (c1, c2, ...)
select c1, c2, ...
from your_table
where id = 1

where c1, c2, ... are all the columns except id. If you want to explicitly insert with an id of 2 then include that in your INSERT column list and your SELECT:

insert into your_table (id, c1, c2, ...)
select 2, c1, c2, ...
from your_table
where id = 1

You'll have to take care of a possible duplicate id of 2 in the second case of course.
