Postgresql Tables Exists, But Getting "Relation Does Not Exist" When Querying

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;

Postgresql tables exists, but getting relation does not exist when querying

You have to include the schema if isnt a public one

SELECT *
FROM <schema>."my_table"

Or you can change your default schema

SHOW search_path;
SET search_path TO my_schema;

Check your table schema here

SELECT *
FROM information_schema.columns

Sample Image

For example if a table is on the default schema public both this will works ok

SELECT * FROM parroquias_region
SELECT * FROM public.parroquias_region

But sectors need specify the schema

SELECT * FROM map_update.sectores_point

relation does not exist in postgreSQL but already exist

The problem was that PostgreDB wants me to use SELECT colum FROM schema.table instead of SELECT colum FROM table. And that's all. Thanks everyone

I keep getting the error relation [TABLE] does not exist

Each element has to be quoted individually:

select "ID" 
from "Schema"."table1";

More details about quoted identifiers are in the manual

PostgreSQL error: relation Table does not exist

Before this two tables have you created this tables:

  • Users
  • Cinemas
  • Actor
  • Director
  • UserComments

If you have not then both of this tables will not be created.

Also please check have you created a type called RATE.

If you have already created tables I have mentioned and datatype RATE make sure you have primary key's in this table so your foreign key's can reference them.

Then, if you have done all of this do check the comment from @TheImpaler: "DEFAULT '000' on a primary key (or any key) makes little sense.".

Also, when you have primary key on the column you do not need NOT NULL constraint.

After all of that you will have two codes that work:

After commenting with the OP I have discovered that he can create the table by referencing the schema before the table name like this:

create table schema_name.Series...

Postgresql column exists, but getting column of relation does not exist

If you have table names with upper case you have to enclose the table with double quotes

insert into messages( "replyDate") values('2021-05-07T11:33:36.721Z'),('2021-05-07T11:33:39.704Z'),('2021-05-07T11:33:42.414Z'),('2021-05-07T11:33:42.422Z'),('2021-05-07T11:33:49.454Z')
