如何计算查询结果中的值

Question

我想计算查询结果的值，但如果有意义，则在同一查询中。原始查询是

SELECT CLOSING_FEE+CLOSING_FEE_INT+CLOSING_INS+CLOSING_INT+CLOSING_OTHER as BAL, total_closing_balance
FROM statement

这会返回超过4000行。我想检查两个加起来。有没有办法在同一个查询中使用count函数来计算select语句的前两个值？

或者我是否必须使用像临时表这样的东西然后计算？

Answer 1

使用Select sum(CLOSING_FEE+CLOSING_FEE_INT+CLOSING_INS+CLOSING_INT+CLOSING_OTHER )

它将添加所有这些细节。

Answer 2

如果total_closing_balance是静态的话，请尝试这个

 SELECT SUM(CLOSING_FEE+CLOSING_FEE_INT+CLOSING_INS+CLOSING_INT+CLOSING_OTHER) as BAL, MAX(total_closing_balance) AS total_closing_balance FROM isql.VW_300_statement WHERE brand = '1'AND DAT = '2013-01-18 00:00:00.00000'AND INS_TYPE =''group by Brand,DAT

Answer 3

为了计算查询结果的行数，您必须按如下方式编写查询：

select count(*)
from (SELECT CLOSING_FEE+CLOSING_FEE_INT+CLOSING_INS+CLOSING_INT+CLOSING_OTHER as BAL, total_closing_balance
FROM isql.VW_300_statement
WHERE brand = '1'
AND DAT = '2013-01-18 00:00:00.00000'
AND INS_TYPE ='')
