== Restoring a table from .frm and .ibd files == | |||
Assuming you already have a running database, this demonstrates a restore of a table into a temporary database. | |||
# Create a temporary database | |||
#: Use a <code>create database</code> or other means to create a temporary database to use as to restore the table. | |||
# Restore the structure of the table | |||
#: Use '''mysqlfrm''' tool to extract ''create table'' script. | |||
#: <code>mysqlfrm -server=root:password@localhost -port=3311 "path/to/mytable.frm" > "path/to/recovered_mytable.sql"</code> | |||
# Recreate the table | |||
#: Create the table using the generated script, or previously existing script that matches the backup structure. | |||
# Replace .ibd file. | |||
#: Remove the newly created .idb file by executing the following: <source lang="mysql">> ALTER TABLE mytablename IMPORT TABLESPACE;</source> | |||
#: Copy the restored .ibd file into the folder that contains the .ibd file. | |||
# Reactivate the table | |||
#: Re-establish the link. <source lang="mysql">> ALTER TABLE mytablename IMPORT TABLESPACE;</source> | |||
#: You can usually ignore the warnings (sometimes even errors) that show up. | |||
