When you wrote "mysql client program" I'm assigning you mean the Python code I'm writing, the answer is no the stored procedure crashes.

As for create table statements...

This with this data using the parameter "fred" it should work.
call getSettingsUploadStock("fred")


Using any other parameter the stored procedure should still function however the result will tell you that there is no data for that value.
call getSettingsUploadStock("bob")


But if you look at the bottom of stored procedure you will see three select statements which are the three datasets that should be returned. Comment out any two and everything functions.

select err_ID, err_Category, err_Name, err_Long_Description, err_Values
from temp_errors;

select tmp_id, tmp_name, tmp_version, tmp_filetype, tmp_has_header, tmp_prefix
from temp_upload_type;

select tmp_id, tmp_supplier_id, tmp_name, tmp_header_text, tmp_mysql_name, tmp_field_type
from temp_upload_type_field;

But if you return more than one dataset it crashes.
