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

Answer 1

I also have development and production servers with the same database structure.

I modified indexes on both of them so I wanted to merge all together. So I needed to compare data with Notepad+.

Here is how you export indexes for all tables, all databases and how to filter and compare them:

--- Single table:
    SHOW INDEX FROM mydb.mytable;
    SHOW INDEX FROM mytable;

--- Multi tables, databases:
    USE information_schema;
    SELECT * FROM `statistics` ORDER BY TABLE_SCHEMA ASC, TABLE_NAME ASC, INDEX_NAME ASC;

Now, phpMyAdmin -> Export to CSV-Excel:

add a header row -> delete all columns but leave "database_name table_name index column value"

Then, filter by database.

Copy all from database1 to a notepad+ screen 1, filter excel database2, copy all to notepad+ screen 2 -> COMPARE!
