pgAdmin error - relation “[name of function/Views/Trigger Functions]” does not exist

Question

I\'m just new to pgAdmin, so I don\'t really know what causes these errors:

ERROR:  relation \"ongoingprojects\" doe         


        

Answer 1

Pay careful attention to the error message:

ERROR: relation "ongoingprojects" does not exist

Note that it is complaining about ongoingprojects when your SQL talks about ongoingProjects. You probably created the table with something like:

create table "ongoingProjects" ( ...

PostgreSQL folds all identifiers (table names, column names, ...) to lower case unless they are double quoted. Once you've created the table as "ongoingProjects", you'll have to double quote the name everywhere and exactly match that case:

select * from "ongoingProjects";

The usual practice with PostgreSQL is to create tables with unquoted names in lower case with word separated using underscores:

create table ongoing_projects ( ...

so that you don't have worry about quoting.
