Question

I’m messing around with a tutorial
http://www.kendoui.com/blogs/teamblog/posts/12-01-18/get_rolling_with_kendo_ui_and_php_ndash_part_1.aspx

and using the postgres northwind port from here:
http://code.google.com/p/northwindextended/downloads/detail?name=northwind.postgre.sql

I cannot get this query to execute on the db:

SELECT TRIM(t.TerritoryDescription) AS TerritoryDescription
            FROM Territories t                 
            INNER JOIN EmployeeTerritories et ON t.TerritoryID = et.TerritoryID    
            INNER JOIN Employees e ON et.EmployeeID = e.EmployeeID           
            WHERE e.EmployeeID = 1

The error is:

ERROR:  column t.territoryid does not exist
LINE 3:             INNER JOIN EmployeeTerritories et ON t.Territory

but the table territories and the territoryid column are both there.

Answer 1

The problem is that in the SQL that you have used to create the database, you are using quoted column names:

CREATE TABLE territories (
    "TerritoryID" character varying(20) NOT NULL,
    "TerritoryDescription" bpchar NOT NULL,
    "RegionID" smallint NOT NULL
);

Since you used quoted names, postgres expects the column case to match. However it will by default lowercase all column names:

PostgreSQL automatically folds all identifiers (e.g. table/column
names) to lower-case values at object creation time and at query time.
To force the use of mixed or upper case identifiers, you must escape
the identifier using double quotes (“”).

From the PHP pgsql documentation.

So, quote your column names in "" when you execute the query.
