mysql导出索引sql 导出索引创建语句

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 ='数据库名' AND TABLE_NAME='表名' GROUP BY TABLE_NAME, INDEX_NAME ORDER BY TABLE_NAME ASC, INDEX_NAME ASC;

 

如果想导出数据库所有表的索引，直接去掉上面表名的条件即可
