how_to_use_ant_query_data_and_mail

        下面的示例是一个用Ant执行数据库查询并通过Javamail发送邮件的例子，要完成相同的功能，请先安装下列步骤执行操作：

        1、安装j2sdk1.4.2，并设置path和classpath
        2、安装Ant161，加到path中去。
        3、下载javamail-1.3.1，并在classpath中指定mail.jar
        4、下载jaf-1.0.2，并在classpath中指定activation.jar
        5、编辑buildfile文件，例如night_build.xml。
        6、执行：ant -buildfile night_build.xml
        7、添加计划任务（Linux下采用cron），定时执行以上脚本就可以实现nightly building。

        night_build.xml脚本如下：

<?xml version="1.0" encoding="GB2312"?>
<project default="init" name="Project Argon">
     <description>
          A Simple project doing the nightly build in ant build file
     </description>
     <property name="sqlDir" location="sql"/>
     <property name="logDir" location="log"/> 
     <property name="attachmentDir" location="attachment"/>
     <tstamp>
         <format property="creDate" pattern="yyyy-MM-dd"/>
     </tstamp>
     <!-- XML comments can also be used -->
     <target name="init">
          <mkdir dir="${sqlDir}"/>
          <mkdir dir="${logDir}"/>
          <mkdir dir="${attachment}"/>
          <sql
              driver="oracle.jdbc.driver.OracleDriver"
              url="jdbc:oracle:thin:@192.168.15.250:1521:ycdb"
              userid="training"
              password="deep1704sea"
              src="./sql/queryData.sql"
              showheaders="false"
              print="yes"
              output="${attachmentDir}/outputfile${creDate}.txt"  
          >
          </sql>
          <mail mailhost="email.ctgpc.com.cn" mailport="25" subject="TGPMS一周数据报告_${creDate}" charset="utf-8">
              <from address="[email protected]"/>
              <to address="[email protected]"/>
              <message>您现在看到的是由系统发出的TGPMS一周数据报告.</message>
              <fileset dir="${attachmentDir}">
                  <include name="*.txt"/>
              </fileset>
          </mail>
     </target>
</project>

    queryData.sql脚本如下：

        SELECT 'Nightly Building begining: '||sysdate FROM dual;
        SELECT '昨日D8512中新增'||COUNT(*)||'条工序编号'  FROM process_no
        WHERE modify_date>=sysdate-1;
        SELECT '昨日D8512中新增'||COUNT(*)||'条指标编号' FROM process_test_index
        WHERE modify_date>=sysdate-1;
