mysql 批量修改表列明為大小寫

 

根據表名 修改為小寫

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

 

根據庫名 修改為小寫

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

WHERE
TABLE_SCHEMA = '數據庫名'

 大寫的話 把  LOWER 改成 UCASE
