REFERENCES command denied to user ''@'localhost' for table 'table_name'

Looks like some permissions need to be updated before we can test out foreign keys.

Hello James, it is fixed, foreign key creation now works :)

Hallo,
I have problem with:

select top (5)
from....

The error is: execute command denied to user ''@'localhost' for routine 'top'

Cyril (Admin)-2020-11-03 12:58

Hello,

top is not supported by MySQL. You can use LIMIT:

Select * from MyTable Limit 3

SELECT * FROM Employee WHERE doj IS NULL; -> is not working, neither is 'WHERE doj IS NOT NULL'.

Everything else is awesome. Thank you very much for this webiste.
