Re: [GENERAL] Syntax error needs fresh eyeballs

From: Rich Shepard
   My schema includes three tables and psql throws an error I'm not seeing when I try to read the schema into the database. I'd appreciate fresh eyes looking at the table and learning what error I'm not seeing.

   The tables:

CREATE TABLE Weather (

   site_id INTEGER PRIMARY KEY,

   site_name TEXT,

   site_location TEXT

);

CREATE TABLE Weather_Params (

   site_id INTEGER

              REFERENCES Weather(site_id),

   param TEXT,

   param_unit TEXT,

   freq INTEGER,

   freq_unit TEXT,

   equip TEXT,

   PRIMARY KEY (site_id, param)

);

CREATE TABLE Weather_Data (

   site_id INTEGER

              REFERENCES Weather(site_id),

   monit_date DATE,

   monit_time TIME,

   read_by TEXT,  -- name of employee collecting data

   param TEXT

              REFERENCES Weather_Params(param),

   param_value REAL,

   PRIMARY KEY (site_id, monit_date, monit_time, param) );

   The error:  ERROR:  there is no unique constraint matching given keys for referenced table "weather_params".

-----------------------

Just a guess...You've camel-cased the table names but aren't using double quotes.  Try either lower-casing all table names and references to them, or double-quoting all identifiers.
