go-tpc tpch run Command Not Working for MySQL

[abdelnassergit]

Hi,

I'm encountering an issue with the go-tpc tpch run command when trying to connect to a MySQL database. The prepare command works fine, but the run command fails with the error "cannot connect to the database". Here are the details of my setup:



I also try it why mysql 8.0 with no success.
When i try to run with an inexistant database i have this error :

Unknown system variable 'tidb_default_string_match_selectivity' ???
Any assistance or guidance on resolving this issue would be greatly appreciated. Thank you!
