MySQL error: mismatched types; Rust type i32 while decoding column 4

[nettonet]

Describe the bug

Hi, thanks for the great tool.
I'm running dbscope against a MySQL database and hit the following error:

MySQL: error occurred while decoding column 4: mismatched types; Rust type i32``

The column in question is a nullable integer field. Some rows contain NULL, and the rest are regular integers within the i32 range.

Not sure if this is related to the way dbscope infers schema or handles nulls. Would appreciate any pointers or a fix.

Happy to provide more info if needed.

Thanks!
