MySql, bagaimana saya bisa mengekspor indeks dari database pengembangan saya ke database produksi saya?

Mungkin maksud Anda "Bagaimana cara membuat ulang indeks pengembangan saya di basis data langsung (yang sudah ada)"?

Jika demikian, saya pikir perintah SQL yang Anda cari adalah;

TAMPILKAN BUAT TABEL {tablename};

ALTER TABLE ADD INDEX {index_name} (col1, col2)

ALTER TABLE DROP INDEX {index_name}

Anda dapat menyalin baris "KEY" dan "CONSTRAINT" dari output "SHOW CREATE TABLE" dan meletakkannya kembali di "ALTER TABLE ADD INDEX".

dev mysql> SHOW CREATE TABLE city;
CREATE TABLE `city` (
  `id` smallint(4) unsigned NOT NULL auto_increment,
  `city` varchar(50) character set utf8 collate utf8_bin NOT NULL default '',
  `region_id` smallint(4) unsigned NOT NULL default '0',
  PRIMARY KEY  (`id`),
  KEY `region_idx` (region_id),
  CONSTRAINT `city_ibfk_1` FOREIGN KEY (`region_id`) REFERENCES `region` (`id`) ON UPDATE CASCADE ON DELETE RESTRICT
) ENGINE=InnoDB;

live mysql> SHOW CREATE TABLE city;
CREATE TABLE `city` (
  `id` smallint(4) unsigned NOT NULL auto_increment,
  `city` varchar(50) character set utf8 collate utf8_bin NOT NULL default '',
  `region_id` smallint(4) unsigned NOT NULL default '0',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB;

live mysql> ALTER TABLE `city` ADD KEY `region_idx` (region_id);
live mysql> ALTER TABLE `city` ADD CONSTRAINT `city_ibfk_1` FOREIGN KEY (`region_id`) REFERENCES `region` (`id`) ON UPDATE CASCADE ON DELETE RESTRICT;

Semoga ini bisa membantu!
