问题 I'm just new to pgAdmin, so I don't really know what causes these errors: ERROR: relation "ongoingprojects" does not exist LINE 1: SELECT * FROM ongoingProjects; ^ ********** Error ********** ERROR: relation "ongoingprojects" does not exist SQL state: 42P01 Character: 15 Even if the function/view exists in the schema.

问题 I have two tables that have a column named id_user in common. These two tables are created in my Drupal webpage at some point (that I don't know because I didn't created the Netbeans project). I checked on the internet and found that probably by adding REFERENCES 1sttable (id_user) to the second table, it should copy the value of the 1sttable (that is always created when a new user arrives) to the id_user value of the 2ndtable (that I don't know at which point is created). Is it correct? If

问题 I am using pgAdmin to connect remotely to my database as phpPgAdmin is a bit limited in its features. Only problem is if I leave the SQL window open without running a query for a few minutes, then it says I need to reconnect.
