Question

之前提问过一个问题，现在自己看来确实不是一个好问题，描述模糊不清，谢谢指正

Answer 1

What is a good question?

At least make the following points clear:

1. What environment, what version

2. What operation was done, the specific operation action: the command executed, what sql was executed

3. What is the specific problem? "There is a problem with the data after verification"? Only the devil knows what the problem is

4. "The amount of imported data is too large"? How loud is it?

5. udf? What udf was used?

I have nothing, so I came to ask questions. Are you expecting divine help?
