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;
