Hello!
I followed the instruction you wrote me.
But at that point:" load web2py app, ensure migrate is true, so that will
create the tables defined in web2py"
I have this error:

I just created the db "gadb" in mysql.exe. You can see the db, but I only
created the db with the command
mysql> create database gadb; Query OK, 1 row affected (0.02 sec) mysql>
show databases; +--------------------+ | Database | +--------------------+
| gadb | | information_schema | | mysql | | performance_schema | | sakila |
| sys | | world | +--------------------+ 7 rows in set (0.00 sec)
Can you help me what is my mistake?
THANK YOU
