（四）IBATIS + ORACLE
第一部分：基础篇
1.4.1.1 分页SQL
<!-- 开头 -->
<isNotNull prepend="" property="end">
SELECT * FROM (
</isNotNull><!-- 结尾 -->
<isNotNull prepend="" property="end">
<![CDATA[ WHERE ROWNUM<=#END#) WHERE ROWINDEX>=#START# ]]>
</isNotNull>1.4.1.2 $column$
执行sql语句时，控制台输出的语句，在该位置不会以问号的形式出现，而是直接填充其对应的值
1.4.1.3 日期类比较大小
<isNotEmpty prepend="and" property="BEGINDATE">
<![CDATA[
T.SCHEDULE_DATE >= TO_DATE(#BEGINDATE#,'yyyy-MM-dd')
]]>
</isNotEmpty>
<isNotEmpty prepend="and" property="ENDDATE">
<![CDATA[
T.SCHEDULE_DATE <= TO_DATE(#ENDDATE#,'yyyy-MM-dd')
]]>
</isNotEmpty>1.4.1.4 从Oracle服务器获取当前系统日期
<select id="getSYSDATE" resultClass="java.lang.String">
SELECT TO_CHAR(SYSDATE,'yyyy-MM-dd hh24:mm:ss') AS SYSTEMDATE FROM DUAL
</select>dao层配置
/**
* 获取Oracle服务器时间
* @return 系统当前时间
*/
public String getSYSDATE() throws DaoException {
try {
return (String)sqlMapClient.queryForObject("telemedicine.service.bo.remoteCons.schedule.getSYSDATE");
} catch (SQLException e) {
String err = "查询系统当前时间出错->出错原因:" + e.getMessage();
log.error(err, e);
throw new DaoException(err, e);
}
}1.4.1.5 增加
方式一：主键使用序列生成
<insert id="insertTSORGDIAITEM" parameterClass="map">
<selectKey resultClass="java.math.BigDecimal" keyProperty="FID" >
SELECT STSORGDIAITEM.NEXTVAL AS FID FROM DUAL
</selectKey>
INSERT INTO TSORGDIAITEM(FID,
FORGID,
FITEMCODE,
FITEMTYPE,
FCURCODE,
FCENCODE,
FITEMNAME,
FZJM,
FITEMSPEC,
FUNIT,
FPRICE)
VALUES(#FID :NUMERIC#,
#FORGID :NUMERIC#,
UPPER(#FITEMCODE :VARCHAR#),
#FITEMTYPE :NUMERIC#,
#FCURCODE :VARCHAR#,
#FCENCODE :VARCHAR#,
UPPER(#FITEMNAME :VARCHAR#),
UPPER(#FZJM :VARCHAR#),
#FITEMSPEC :VARCHAR#,
#FUNIT :VARCHAR#,
#FPRICE :NUMERIC#)
</insert><insert id="insertCONSULT_DEPENT_DOCTOR_INFO" parameterClass="map">
<selectKey keyProperty="id" resultClass="java.lang.String">
select sys_guid() as id from dual
</selectKey>
INSERT INTO CONSULT_DEPENT_DOCTOR_INFO(DEPENT_DOCTOR_INFO_ID,CONSULT_APPLY_ID,CONSULT_DEPENT_ID,CONSULT_DEPENT,CONSULT_DOCTOR_ID,CONSULT_DOCTOR,DOCTOR_PHONE)
VALUES(#id#,#CONSULT_APPLY_ID#,#CONSULT_DEPENT_ID#,#CONSULT_DEPENT#,#CONSULT_DOCTOR_ID#,#CONSULT_DOCTOR#,#DOCTOR_PHONE#)
</insert>注意：
a.selectKey标签的keyProperty属性：查询出来的结果会被放到这个字段里面；必须指明返回的数据类型：resultClass；select ... 别名 from dual 别名可以任意取；
b.执行插入语句后，默认返回的是主键。
1.4.1.6 WHERE条件<!-- 通用查询条件 -->

</select>注意：
a.增，删，改这3个操作无需指明返回的数据类型，执行SQL语句，会默认返回影响行数：Integer；
b.如果将Map作为查询的返回数据类型，必须指定resultClass="java.util.HashMap"。

在ibatis框架当中，插入数据的同时，如何返回主键？
执行insert，默认返回的是插入行数。
要想返回主键的话，需要使用<selectKey>标签先将主键查询出来，再执行插入语句。
<selectKey keyProperty="PATIENT_INFO_ID" resultClass="java.lang.String">
select sys_guid() from dual
</selectKey>
打个断点，验证一下。
我们可以看到，此时，在执行插入语句后，主键就返回过来了。
同时，如果我们使用的是Map作为入参的话，keyProperty的值也会作为Map当中的key。
