[英]Adding a populated column to an existing table
I have 2 table that have table counts in them. 我有2个表,其中有表计数。 Something like Table 1: 如表1所示:
New_Counts
100
Table 2: 表2:
Old_Counts
97
I want to create a single QC table so I can eventually check that the counts are increasing: 我想创建一个QC表,以便最终检查计数是否在增加:
New_Counts|Old_Counts
100|97
Any ideas how to do this in SQL? 任何想法如何在SQL中执行此操作? A join won't work since the counts are never the same. 联接将无法正常工作,因为计数永远不会相同。
select newcount,oldcount
from (select
(select count(*) newcount from table1) newcount,
(select count(*) oldcount from table2) oldcount
from dual);
