MySql, how can I export indexes from my development database to my production database?

Question

I\'ve been working on my development database and have tweaked its performance.

However, to my surprise I can\'t find a way to export the indexes to my production da

Extending on @origo's answer. There is a case where i needed to extract the DDL for a bunch of indexes. This script does the job.

SELECT
CONCAT(
'ALTER TABLE ' ,
TABLE_NAME,
' ',
'ADD ',
IF(NON_UNIQUE = 1,
CASE UPPER(INDEX_TYPE)
WHEN 'FULLTEXT' THEN 'FULLTEXT INDEX'
WHEN 'SPATIAL' THEN 'SPATIAL INDEX'
ELSE CONCAT('INDEX ',
INDEX_NAME,
' USING ',
INDEX_TYPE
)
END,
IF(UPPER(INDEX_NAME) = 'PRIMARY',
CONCAT('PRIMARY KEY USING ',
INDEX_TYPE
),
CONCAT('UNIQUE INDEX ',
INDEX_NAME,
' USING ',
INDEX_TYPE
)
)
),
'(',
GROUP_CONCAT(
DISTINCT
CONCAT('', COLUMN_NAME, '')
ORDER BY SEQ_IN_INDEX ASC
SEPARATOR ', '
),
');'
) AS 'Show_Add_Indexes'
FROM information_schema.STATISTICS
WHERE TABLE_SCHEMA = 'PLEASE CHANGE HERE'
GROUP BY TABLE_NAME, INDEX_NAME
ORDER BY TABLE_NAME ASC, INDEX_NAME ASC;
