　　（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>

　　　　　方式二：主键采用sys_guid()生成

<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 -->
<sql id="DIRECTORY_ERROR_WHERE">
    <dynamic prepend=""> <!-- 或prepend="and" -->
        <isNotEmpty prepend="and" property="FORGID">
            T.FORGID = #FORGID#
        </isNotEmpty>
        <isNotEmpty prepend="and" property="FICDCODE">
            (UPPER(T.FICDCODE) LIKE UPPER(#FICDCODE# || '%') OR T.FICDCODE LIKE #FICDCODE# || '%')
        </isNotEmpty>
        <isEqual prepend="and" property="FERRORSTATUS" compareValue="0">
            T.FCENCODE IS NULL
        </isEqual>
        <isEqual prepend="and" property="FERRORSTATUS" compareValue="1">
            T.FITEMNAME !=T1.FITEMNAME
        </isEqual>
        <isNotEmpty prepend="and" property="FRCODE">
            T.FRCODE = '$FRCODE$'
        </isNotEmpty>
    </dynamic>
</sql>

　　　 1.4.1.7 更新

　　　　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"。
