對返回值執行操作

Question

我需要從數據庫返回測量數據。不幸的是數據在不同數量（kWatt，我需要瓦特），並希望最好做轉型中的SQL語句

所以我要多與1000 measuremententry在

SELECT measuremententry FROM日誌

這可能嗎？

感謝

Answer 1

SELECT measuremententry * 1000 AS measuremententry 
    FROM log 

Answer 2

如何是這樣的：在PostGre

SELECT kilowatts * 1000 as watts FROM log 

Answer 3

SELECT measuremententry * 1000 FROM log 

工作對我來說，應該爲你工作

Answer 4

你應該能夠做到

SELECT measuremententry * 1000 FROM log 

Answer 5

SELECT measuremententry * 1000 as measurementrytry FROM log
