如何在MySQL中删除此索引？

Question

它是这样创建的:

create table listings(
    id integer unsigned NOT NULL AUTO_INCREMENT,
    accountId  integer unsigned default null,
    title varchar(300) not null,
    country integer unsigned,
    region integer unsigned,
    type integer unsigned,
    price integer,
    unit varchar(20) not null,
    priceUSD decimal(12,2),
    bedrooms integer unsigned,
    thumbnail varchar(100) default null,
    keywords text,
    created datetime,
    deleted boolean default 0,
    fulltext index (keywords),
    PRIMARY KEY (id)
) engine=MyISAM;

如何删除没有名称的全文索引？

如果未命名的指数是什么:fulltext index (title ,keywords)？

Answer 1

ALTER TABLE listings DROP INDEX keywords;

Answer 2

在mysql客户端中运行此命令:

mysql> SHOW CREATE TABLE listings;

它将显示表的DDL,包括系统为索引指定的名称.

Answer 3

ALTER TABLE {your_table_name} DROP INDEX {your_index_name}

要么

DROP INDEX {your_index_name} ON {your_tbl_name}
