select 语句中的 参数值被当成关键字了

sql查询语句(SELECT account_id FROM `taobao_office`.`cloud_yunpan` WHERE dt='2021-04-12' AND target='update')中的 ’update‘ 参数值被当成关键字了，把’update‘ 换成其它值就不报错，最新版(druid-1.2.5.jar)也存在bug

**出错方法：**
com.alibaba.druid.sql.SQLUtils#parseStatements(java.lang.String, com.alibaba.druid.DbType)

**错误详情：**

Start with the SQLUtils#parseStatements entry point and the SQLExprParser.primary and HiveExprParser.primary frames named in the report. Reproduce the SELECT using target='update', then trace why UPDATE is treated as a token rather than a quoted value. Done means this query parses successfully while keyword handling remains correct.
