ibaits插入即获取主键(mssql,mysql,oracle)

oracle主键需预先生成，通过sequence；mysql和mssql是插入后生成。

mysql:

<insert id="insertStu_mysql" parameterClass="stu">
insert into stu(name) values (#name#)
<selectKey resultClass="int" keyProperty="id" >
select LAST_INSERT_ID() selectKey>
insert>ibatis测试代码：SqlMapClient client = SqlConfig.getSqlClient();
Stu s = new Stu();s.setName(“test”);

client.insert("insertStu-mysql",s);
//获取主键
System.out.print(" pk = " + s.getId());------------------------------------------------------------------ oracle:预先通过sequence获取insertStu-oracle" parameterClass="stu">
int" type="pre" keyProperty="id" >
SELECT STOCKIDSEQUENCE.NEXTVAL AS VALUE FROM DUAL

insert into STU (ID,NAME) values (#id#,#name#)
mysql ：插入后生成

<insert id="insertStu-mssql" parameterClass="stu">
insert into STU(name) values (#name#)
<selectKey resultClass="int" keyProperty="id" >
select @@IDENTITY as value
<selectKey>
<insert>
