Cannot simply use PostgreSQL table name ("relation does not exist")

From what I've read, this error means that you're not referencing the table name correctly. One common reason is that the table is defined with a mixed-case spelling, and you're trying to query it with all lower-case.

In other words, the following fails:

CREATE TABLE "SF_Bands" ( ... );SELECT * FROM sf_bands;  -- ERROR!

Use double-quotes to delimit identifiers so you can use the specific mixed-case spelling as the table is defined.

SELECT * FROM "SF_Bands";

Re your comment, you can add a schema to the "search_path" so that when you reference a table name without qualifying its schema, the query will match that table name by checked each schema in order. Just like PATH in the shell or include_path in PHP, etc. You can check your current schema search path:

SHOW search_path  "$user",public

You can change your schema search path:

SET search_path TO showfinder,public;

I had problems with this and this is the story (sad but true) :

1. If your table name is all lower case like : accountsyou can use: select * from AcCounTs and it will work fine

2. If your table name is all lower case like : accountsThe following will fail:select * from "AcCounTs"

3. If your table name is mixed case like : AccountsThe following will fail:select * from accounts

4. If your table name is mixed case like : AccountsThe following will work OK:select * from "Accounts"

I dont like remembering useless stuff like this but you have to ;)

Postgres process query different from other RDMS. Put schema name in double quote before your table name like this, "SCHEMA_NAME"."SF_Bands"
