oracle自增，返回插入记录的ID02

1、oracle自增是在SEQUENCE设置；可以在这个文件中设置自增规则；插入一条记录：

insert into student(student_id,first_name,last_name) values(seq_student.nextval,'','');

seq-student是自增规则的名字，seq_student.nextval主键自增；

2、插入一条数据，返回插入数据的ID；keyProperty是插入对象的属性，也就是与表中主键ID对应的；order="after"是在插入之后执行，SEQ_A_MODEL_LOSS是主键自增规则的名字，SEQ_A_MODEL_LOSS.CURRVAL是获取插入的主键值，DUAL是oracle中的虚拟表，来构成select的语法规则，oracle保证dual里面永远只有一条记录。

    <insert id="addLossModel">
        <selectKey resultType="long" order="AFTER" keyProperty="modelId">
            SELECT SEQ_A_MODEL_LOSS.CURRVAL as ID from DUAL
        </selectKey>
        INSERT INTO A_MODEL_LOSS (MODEL_ID,MODEL_CATE_ID,MODEL_CODE,MODEL_STANDARD_NAME,
        MODEL_TRIVIAL_NAME,MODEL_PINYIN_CODE,MODEL_LPCK_CODE,
        MODEL_TYPE,MODEL_CLASS,MODEL_COUNTRY,MODEL_MADE_IN,
        MODEL_IS_INSURER,MODEL_IS_LOSS,MODEL_IS_PIC,MODEL_BIG_PATH,

        MODEL_STRUCT_TYPE,MODEL_GEAR_BOX,MODEL_IS_ENABLE,MODEL_IS_DELETE,

        VERSION,MODEL_FACTORY,MODEL_DESC,TRAN_EDITION,PART_UPDATE_TIME)
