mysql find duplicates in same table

Comment

## Find ALL duplicate recods by value (without grouping them by value) ##
# to find the duplicate, 
# replace all instances of tableName with your table name
# and all instances of duplicateField with the field name where you look for duplicates
SELECT t1.*
FROM tableName AS t1
INNER JOIN(
	SELECT duplicateField
	FROM tableName
	GROUP BY duplicateField
	HAVING COUNT(duplicateField) > 1
)temp ON t1.duplicateField = temp.duplicateField
order by duplicateField

how to duplicate mysql table

Comment

-- You can duplicate or "clone" a table's contents by executing
> CREATE TABLE new_table AS SELECT * FROM original_table;

-- keep in mind that new new_table inherits ONLY the basic column definitions, null settings
-- and default values of the original_table. It does not inherit indexes and auto_increment
-- definitions.
-------------------------------------------------------------------------------------------

-- To inherit all table definitions
> CREATE TABLE new_table LIKE original_table; -- copy table structure only
> INSERT INTO new_table SELECT * FROM original_table; -- add data from old table
