mysql查看索引与存储过程创建索引:

CREATE INDEX可对表增加普通索引或UNIQUE唯一索引。

CREATE INDEX index_name ON table_name (column_list)

CREATE UNIQUE INDEX index_name ON table_name (column_list)

ALTER TABLE用来创建普通索引、UNIQUE索引或PRIMARY KEY主键。

ALTER TABLE table_name ADD INDEX index_name (column_list)

ALTER TABLE table_name ADD UNIQUE (column_list)

ALTER TABLE table_name ADD PRIMARY KEY (column_list)

查看索引

mysql> show index from tablename;

mysql> show keys from tablename;

Non_unique 唯一约束为0。非唯一约束为1。

删除索引

可利用ALTER TABLE或DROP INDEX语句来删除索引

DROP INDEX index_name ON talbe_name

ALTER TABLE table_name DROP INDEX index_name

ALTER TABLE table_name DROP PRIMARY KEY

查询数据库的存储过程:select `name` from mysql.proc where db = 'db_name' and `type` = 'PROCEDURE'

或者

show procedure status

查看函数:

select `name` from mysql.proc where db = 'db_name' and `type` = 'function'

或者

show function status

查看存储过程与函数内容:show create procedure proc_name;

show create function func_name;

如果需要修改存储过程与函数,先drop 再create.

其它数据库参数查看:mysql> help show mysql> Show Global Status, mysql> Show global variables, mysql> Show full processlist, mysql> show engines; mysql> show status; mysql> desc tablename; mysql> show databases; mysql> use database_name;
