ibatis中mysql、oracle的區別

ibatis中mysql、oracle的區別：

mysql中主鍵自動增長爲後生成主鍵
例如：
<insert id="insert" parameterClass="student">
insert into student(name,profession) values(#name#,#profession#)
<selectKey resultClass="java.lang.Integer" keyProperty="id">
<![CDATA[SELECT LAST_INSERT_ID() AS ID]]>
</selectKey>
</insert>

oracle中主鍵自動增長爲預生成主鍵
例如：
<insert id="insert" parameterClass="student">
<selectKey resultClass="java.lang.Integer" keyProperty="id">
SELECT STUDENT_SEQUENCE.NEXTVAL AS ID FROM DUAL
</selectKey>
insert into student(id,name,profession) values(#id#,#name#,#profession#)
</insert>
