如何导出MySQL索引的创建语句

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 = 'TEST' and TABLE_NAME='TEST'
GROUP BY TABLE_NAME, INDEX_NAME
ORDER BY TABLE_NAME ASC, INDEX_NAME ASC；

说明:TABLE_SCHEMA为库名，TABLE_NAME为表名
