数据来自我们的一位客户的文本文件.它完全没有格式化(它是一行很长的文本)，但在 Excel 中可能会这样做.但这对我来说并不实用，因为我需要在我的 sql 查询中使用这些值.每次需要运行查询时都这样做很不方便.
The data comes as a text file from one of our clients. It's totally unformatted (it's a single, very long line of text), but it may be possible to do so in Excel. But it's not practical for me, because I will need to use these values in my sql query. It's not convenient to do so every time I need to run a query.
推荐答案
获取一长串逗号分隔文本的不同值的最简单方法是使用 find an replace with UNION 以获得不同的值.
Simplest way to get the distinct values of a long list of comma delimited text would be to use a find an replace with UNION to get the distinct values.
SELECT 1
UNION SELECT 1
UNION SELECT 1
UNION SELECT 2
UNION SELECT 5
UNION SELECT 1
UNION SELECT 6
应用于您的逗号分隔文本的长行
Applied to your long line of comma delimited text
- 找到并用
UNION SELECT 替换每个逗号 - 在语句前添加
SELECT
您现在应该有一个有效的查询
You now should have a working query
