Description:
There are several places the return value are not handled, which could contain error code:
sql/sql_parse.cc Line 5395: "error"
storage/innobase/row/row0import.cc Line 3797: "err"
sql/sql_executor.cc: Line 4835: "error"
storage/innobase/gis/gis0rtree.cc: Line 875: "ret"
storage/innobase/os/os0enc.cc: Line 1214: "my_ret"
sql/item_func.cc: Line 7895: "res"
storage/innobase/arch/arch0recv.cc: Line 42: "err"

I wonder whether there needs to be any error handling mechanism or at least an assert here.

How to repeat:
It's in mysql-8.0.21

Suggested fix:
Add error handling mechanism or assert.

Hi Mr. Zhong,

Thank you for your bug report.

However, you are using an old release of the 8.0 version.

Can you, please, let us know the exact line numbers in the current release, 8.0.23.

Thanks in advance.
