Mysql 自动增加设定基值的语句

复制代码 代码如下:

ALTER TABLE 表名 AUTO_INCREMENT = 设定的值

复制代码 代码如下:

alter_specification:
ADD [COLUMN] create_definition [FIRST | AFTER column_name ]
or ADD INDEX [index_name] (index_col_name,...)
or ADD PRIMARY KEY (index_col_name,...)
or ADD UNIQUE [index_name] (index_col_name,...)
or ALTER [COLUMN] col_name {SET DEFAULT literal | DROP DEFAULT}
or CHANGE [COLUMN] old_col_name create_definition
or MODIFY [COLUMN] create_definition
or DROP [COLUMN] col_name
or DROP PRIMARY KEY
or DROP INDEX index_name
or RENAME [AS] new_tbl_name
or table_options
eg:
mysql> alter table topics change hotico hot_count int(4);
mysql> alter table topics alter hot_count set default 1;
