MySQL里创建索引(Create Index)的方法和语法结构及例子，

CREATE INDEX Syntax

CREATE [UNIQUE|FULLTEXT|SPATIAL] INDEX index_name
[index_type]
ON tbl_name (index_col_name,...)
[index_type]

index_col_name:
col_name [(length)] [ASC | DESC]

index_type:
USING {BTREE | HASH | RTREE}

 

-- 创建无索引的表格 create table testNoPK ( id int not null, name varchar(10) ); -- 创建普通索引 create index IDX_testNoPK_Name on testNoPK (name);
