在mysql中,可以利用「ALTER TABLE」語句修改表字首,修改表字首可以看做修改表名,利用RENAME可以修改表名,語法為「ALTER TABLE 原表名 RENAME TO 新表名;」。

本教學操作環境:windows10系統、mysql8.0.22版本、Dell G3電腦。

mysql怎麼修改表字首

使用sql語句修改mysql資料庫表字首名

首先我們想到的就是用sql查詢語句來修改,這個方法也很方便,在執行 SQL 查詢框中輸入如下語名就可以了。

ALTER TABLE 原表名 RENAME TO 新表名;

如:

ALTER TABLE old_post RENAME TO new_post;

Sql查詢語句有一個缺點,那就是一句SQL語句只能修改一張資料庫的表名,如果你要精確修改某一張表,很好用。如果資料庫表很多的話,比較麻煩。

但是我們可以通過一條語句一次性生成所有的sql語句:

select concat('alter table ',table_name,' rename to ',table_name) from information_schema.tables where table_name like'dmsck_%';

生成語句如下:

alter table dmsck_acategory rename to dmsck_acategory;
alter table dmsck_address rename to dmsck_address;
alter table dmsck_article rename to dmsck_article;
alter table dmsck_attrcategory rename to dmsck_attrcategory;
alter table dmsck_attribute rename to dmsck_attribute;
alter table dmsck_brand rename to dmsck_brand;
alter table dmsck_cart rename to dmsck_cart;
alter table dmsck_category_attr rename to dmsck_category_attr;
alter table dmsck_category_goods rename to dmsck_category_goods;
alter table dmsck_category_store rename to dmsck_category_store;
alter table dmsck_collect rename to dmsck_collect;
alter table dmsck_comment rename to dmsck_comment;
alter table dmsck_coupon rename to dmsck_coupon;
alter table dmsck_coupon_sn rename to dmsck_coupon_sn;
alter table dmsck_enterprise rename to dmsck_enterprise;
alter table dmsck_filmstrip rename to dmsck_filmstrip;
alter table dmsck_friend rename to dmsck_friend;
alter table dmsck_function rename to dmsck_function;
alter table dmsck_gattribute_rule rename to dmsck_gattribute_rule;
alter table dmsck_gcategory rename to dmsck_gcategory;
alter table dmsck_goods rename to dmsck_goods;
alter table dmsck_goods_attr rename to dmsck_goods_attr;
alter table dmsck_goods_bak rename to dmsck_goods_bak;
alter table dmsck_goods_down_log rename to dmsck_goods_down_log;
alter table dmsck_goods_image rename to dmsck_goods_image;
alter table dmsck_goods_old rename to dmsck_goods_old;
alter table dmsck_goods_qa rename to dmsck_goods_qa;
alter table dmsck_goods_spec rename to dmsck_goods_spec;
alter table dmsck_goods_statistics rename to dmsck_goods_statistics;
alter table dmsck_groupbuy rename to dmsck_groupbuy;
alter table dmsck_groupbuy_log rename to dmsck_groupbuy_log;
alter table dmsck_keyword rename to dmsck_keyword;
alter table dmsck_mail_queue rename to dmsck_mail_queue;
alter table dmsck_member rename to dmsck_member;
alter table dmsck_message rename to dmsck_message;
alter table dmsck_module rename to dmsck_module;

然後將其複製到一個文字檔案中,將要修改的字首統一修改(稍稍麻煩),然後再複製到mysql中執行sql語句就ok了。
