Oracle数据库序列的创建

创建序列，TEST_SEQ是序列名称：

CREATE SEQUENCE TEST_SEQ

minvalue 1

maxvalue 9999999

INCREMENT BY 1

START WITH 1;

查询所有的序列：

SELECT * FROM user_sequences ORDER BY sequence_name;

MyBatis中序列自增的写法：

<insert id="insert" parameterType="com.slmanage.entity.TEST">
    <selectKey keyProperty="ID" resultType="java.lang.Long" order="BEFORE">
        SELECT TEST_SEQ.NEXTVAL FROM DUAL
    </selectKey>
    INSERT INTO TEST (ID, NAME)
    VALUES (#{ID}, #{NAME})
</insert>
