mysql查询某个字段并修改

比如我存储的数据,有的是 山东,有的是山东省

我想统一改为山东省

UPDATE t_security SET province = REPLACE( province, '山东', '山东省' ) WHERE province ='山东';

大同证券改为山西大同证券

UPDATE t_security SET security = REPLACE( security, '大同证券', '山西大同证券' ) WHERE security ='大同证券';

如果我想把股票表的交易所代码全部从SH改为sh

UPDATE t_stock SET exchangeCode = REPLACE( exchangeCode, 'SH', 'sh' ) WHERE exchangeCode ='SH';

SZ改为sz

UPDATE t_stock SET exchangeCode = REPLACE( exchangeCode, 'SZ', 'sz' ) WHERE exchangeCode ='SZ';
