下面的代码是一个包含温度的分组数据样本（请记住它在医院中的人体温度）。
显然数据很糟糕但想知道是否有可能以某种方式将这些数据转换为INT，因为我们有一个UOM（测量单位）字段，所以我们只需要这个数字。
数据问题：
88度显然是华氏温度而不是摄氏温度 3635将是36.35 .368将是36.8 37.3。将是37.3 .37.7将是37.7 377将是37.7 .3.8将是38我认为任何其他变体都应该被排除在无效数据之外，因为无法准确地做出明智的假设。
DECLARE @Test TABLE (
[Temperature] VARCHAR(500),
[Count] VARCHAR(50)

INSERT INTO @Test ([Temperature],[Count])

我相信这会让你接近。
SELECT *,
CASE
WHEN ISNUMERIC(REPLACE(REPLACE(REPLACE(Temperature, 'oC', ''), ' ', ''), '.', '')) = 1
THEN CONVERT(INT, (REPLACE(REPLACE(REPLACE(Temperature, 'oC', ''), ' ', ''), '.', '')))
ELSE NULL END AS TemperatureValue
FROM @Test
希望这可以帮助你。
答案 1 :(得分：1)
这个工作正常，但没有考虑我们保留的DQ问题，因为这是记录的
TRY_CAST(REPLACE(Temperature, 'oC', '') AS DECIMAL(19,8))
