mysql 批量修改表列明为大小写

根据表名修改为小写

SELECT
concat( 'alter table ', TABLE_NAME, ' change column ', COLUMN_NAME, ' ', LOWER( COLUMN_NAME ), ' ', COLUMN_TYPE, ' comment \'', COLUMN_COMMENT, '\';' ) AS '修改脚本'
FROM
information_schema.COLUMNS
WHERE
TABLE_NAME = '表名';

根据库名修改为小写

SELECT
concat( 'alter table ', TABLE_NAME, ' change column ', COLUMN_NAME, ' ', LOWER( COLUMN_NAME ), ' ', COLUMN_TYPE, ' comment \'', COLUMN_COMMENT, '\';' ) AS '修改脚本'
FROM
information_schema.COLUMNS

WHERE
TABLE_SCHEMA = '数据库名'

大写的话把 LOWER 改成 UCASE
