Hi,

I tried a MariaDB update 10.1.32 -> 10.2.19
My data was after that not available any more in the database (mysqld.exe: Incorrect information in file: '.\tst01\tbl01.frm')
I use many databases with tables with virtual columns and subpartitions.

Environment: WIN 10

.err file: attached
mypc.err
my.ini: attached
my.ini
Test Case: sql file to create a database in version 10.1.32 and some Inserts are attached (my.ini also) 1.sql
I update this to version 10.2.19 - at the end mysql_upgrade_service was without a error (mysql_upgrade_service.MySQL.log attached)
mysql_upgrade_service.MySQL.log
The .err file contains already some warnings

[Warning] InnoDB: Table mysql/innodb_table_stats has length mismatch in the column name table_name.  Please run mysql_upgrade

After starting the database, I cannot see the data in the table any more.

Also if I try mysql_upgrade.exe I will get some errors (mysql_upgrade.exe logs.txt) but the data is still not available
mysql_upgrade.exe logs.txt
