I'm using the free version of Vstudio. I think there is a bug in the studio with mysql 5.7 version. With older versions things are OK. Also have to mention, if I connect with every other IDE, i don't receive this error which is..

Error( 1055 ) 42000: "Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'information_schema.STATISTICS.COLUMN_NAME' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by"

This error appears when I roll the mouse cursor over some table name. And this error also appears on every database I tested. event the system mysql database
