HI to all, i agree with all the above possibilities to copy the table, with data, and structure, but all the above queries wont copy the key constraints ( relations). Is there any query that copy index, key fields in mysql

Thanx, it definitely works.
However, I tried to do this on a 15 million record table,
The INSERT INTO statement, being a logged operation, combined with the possibility for the existence of indexes, possibly even clustered ones, makes this an all around inapplicable solution.
Can you think of any alternative.

On 5.1 this method copied all my indexes between tables (they were MyISAM ones).

Also, it can all be done in one command:

CREATE TABLE recipes_new SELECT * FROM production.recipes;

as explained in the MySQL help - http://dev.mysql.com/doc/re...

Doesn't work on a MySQL 4.x server. Might work on MySQL 5.x. This will also supposedly not copy indexes or foreign key constraints. Makes this approach fairly limited.

What most people don't realize is that MySQL stores each table in its own set of flat files. MyISAM, for instance, creates tablename.MYD, tablename.MYI, and tablename.frm files. D = Data, I = Index(es), frm = structure. I've found you can clone a table VERY quickly - even on a heavily-used live production system with millions of rows - by using the file system to copy these files to new names and then running the "FLUSH TABLES", "FLUSH QUERY CACHE", and "RESET QUERY CACHE" MySQL commands. Although, it is best to temporarily take the database offline before cloning, it can be done on a live system. If the destination table/index gets corrupted during the copy, a "REPAIR TABLE" command usually fixes the problem (or re-running the whole process).

yeah the single-line command is a bad scene. Even the two-line command will have issues in some cases, eg if you have foreign key restraints or are inserting rows with autoincrement keys that equal 0 (they get incremented to 1). I wrapped the statements in code used by mysqldump.
Also doing a mysqldump, replacing the table names in the statements, and then loading the resulting dump is another way to do this. It's actually probably more robust than doing it with insert..select, but will be slower and a bit tricky.

It creates a duplicate table but does not copy the constraints and other meta details of a table

This could also be done in one step with the following:

create table recipies_new select * from production.recipies;

Be aware that this method doesn't seem to duplicate any of the indexes from the original table into the new table. [Using MySQL 5.1]
