nuBuilder Forum

In MySQL 5.7 and MySQL 5.6, queries against INFORMATION_SCHEMA.TABLES returned column names in lowercase such as table_name, table_schema.

With the transition to MySQL 8.0, the implementation of INFORMATION_SCHEMA was re-engineered to use views over the transactional data dictionary, leading to column names being returned in uppercase (e.g. TABLE_NAME, TABLE_SCHEMA)

Replace all occurrences of table_name with TABLE_NAME (I counted 7) in nucommon.php and check if the saving error is gone.

Some other issues might come up with your versions (PHP deprecations etc). I highly recommend updating nuBuilder to a newer version if possible.

Perfect!! thanks
I indeed need to update, but I didn't dare to update with errors in the system. Now it looks everything is ok, so now I will update. Thanks for your help

4.5 installed and working
Is it necessary to install all version sequently, or can i just install the latest.

You can install the latest directly.
