我想使用 ODBC 连接从 asp.net C# 将多行数据插入到 Hive 表中

Question

`我写了下面的代码，用于 5 列的多个数据插入，但我需要它用于 100 多列，超过 10 条数据和快速执行。

Need to optimise the above code; above, I create a string of data and a stored name variable, but the above code will not work for more than 100 columns. Can you please help me figure out why I can't store values and insert them into the Hive table?

Thank you in advance.
