问题现象

使用下面语句查询得到的列别名是大写, 但是起的别名是小写, 没有达到我想要的效果

select t.channel as id from T_CHANNEL_INFO t;

 解决方案

select t.channel as "id" from T_CHANNEL_INFO t;

 Java中的使用

sql.append("select B.INFO_TITLE "title", ");
sql.append("       B.INFO_CONTENT "content",  ");
sql.append("       B.IMAGE_PATH "image", ");
sql.append("       B.RELEASE_NAME "userid", ");
sql.append("       B.RELEASE_TIME "reltime", ");
sql.append("       B.EFFECT_START_TIME "starttime", ");
sql.append("       B.EFFECT_END_TIME "endtime" ");
