Azure 逻辑应用中 SQL 列名称的 URI 编码

Question

我有许多从根本上执行以下操作的逻辑应用程序：

在时间触发器上，一组 SQL 存储过程被调用，然后是一系列 Select 语句运行，这些被传送到 CSV table 然后通过电子邮件发送给报告收件人。

该过程在一个问题上运行良好 - SQL 中的许多列中都有空格。

当我在 SQL 中运行 a select [column 1] from table 时，它工作正常。

当我从逻辑应用程序中运行相同 select - 输出已修改为我相信 URI 编码示例：

Column_x0020_1  
result1  
result2  
result3  
etc.

当我运行调试时，我看到这是在执行 SQL 查询的输出中生成的，而不是在 CSV table 的创建中生成的，我没有看不到任何选项来转义空格以使它们不以 URI 格式编码或以编程方式将 URI 编码列 names/data 更改为 'normal' 编码。

所以请帮忙？

Answer 1

您可以使用下面的表达式将URI编码的列名转换为普通格式

 replace(string(body('Execute_a_SQL_query_(V2)')),'_x0020_',' ')

这里是示例输出以供参考

使用 compose 将 URI 编码的列名称移除为普通名称
