REFERENCES Is a SQL keyword used to define a foreign key.

If you have a table/col named with a SQL keyword, you have to wrap the table/col name into specific characters.

MySQL

INSERT INTO `References` (...) ...

MS SQL

INSERT INTO [References] (...) ...

Postgre SQL

INSERT INTO "References" (...) ...

I'm not sure concerning pgSQL, can someone confirm?

In example, nothing (but common sense) prevents you from creating a database named INSERT with a table INTO having a column VALUE(42)

This query works :

USE [INSERT]
SELECT [INTO].[VALUE(42)] FROM [INTO]
