获取当前语句执行时的时间,返回值类型为timestamp(0)。 获取当前语句执行时的时间,返回值类型为timestamp(0)。 获取当前系统的时间,返回值类型为timestamp(0)。此函数不可下推,建议用current_date代替。 now() 获取当前事务时间,返回值类型为timestamptz。
database。 支持多ip端口配置形式,jdbc自动实现了负载均衡,多ip端口配置形式是采取随机访问+failover的方式,这个过程系统会自动忽略不可达IP。 以","隔开,例如jdbc:postgresql://10.10.0.13:8000,10.10.0.14:8000/database

ssDB(DWS) 中进行的基本数据查询。 在进行数据查询之前,请先执行“Analyze”命令生成与数据库表相关的统计信息。统计信息存储在系统表PG_STATISTIC中,执行计划生成器会使用这些统计数据,以生成最有效的查询执行计划。 查询示例如下: 查询各商铺的月度营业额 复制并执行以下语句查询各商铺的月度营业额。
