项目启动时候需要自动查询数据，报了一下错误： 错误信息：
Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is com.yashandb.jdbc.exception.YasException: [line: 0 column: 0] YAS-00004 feature "parseQueryImplictTable" is not implemented yet
Caused by: com.yashandb.jdbc.exception.YasException: [line: 0 column: 0] YAS-00004 feature "parseQueryImplictTable" is not implemented yet
问题原因 HikariDataSource的connection-test-query语句 书写不规范
解决办法： HikariDataSource的connection-test-query
原来的写法
connection-test-query: select 1
修改为
connection-test-query: select 1 from dual
以下为全部的配置，以供参考
datasource:
type: com.zaxxer.hikari.HikariDataSource
hikari:
minimum-idle: 5
maximum-pool-size: 100
auto-commit: true
idle-timeout: 600000
pool-name: HikariCP
max-lifetime: 600000
connection-timeout: 60000
connection-test-query: select 1 from dual
url: jdbc:yasdb://0.0.0.0:1688/TEST
username: TEST
password: test
driver-class-name: com.yashandb.jdbc.Driver
如果还是不行，可以使用sys用户连接数据库 执行alter system set AUDIT_SYS_OPERATIONS=TRUE scope=memory;再次尝试
