在没有分布统计信息的情况下,执行该查询时,动态sql的一个快照返回以下监视器值(假定所需的监视器开关已激活)。
When the query is executed without distribution statistics, a snapshot for dynamic SQL returns the following monitor values (given that the required monitor switches are active).
这些能量态的水平代表0或者1,就像传统计算机使用晶体管的开关状态来代表数据位0或1一样。
Those levels represent a one or zero, just as the off and on states of a transistor correspond to zero or one bits of data in traditional computing.
