Omitting the double quote to do query on PostgreSQL
Simple question, is there any way to omit the double quote in PostgreSQL?
Here is an example, giving select * from A;, I will retrieve ERROR: relation "a" does not exist, and I would have to give select * from "A"; to get the real result.
Is there any way not to do the second and instead do the first on PostgreSQL?
Answer
Your problem with this query started when you created your table. When you create your table, don't use quotes.
Use this:
CREATE TABLE a ( ... );
Not this:
CREATE TABLE "A" ( ... );
The latter will make it so that you always have to quote it later. The former makes it a normal name and you can use SELECT * FROM a; or SELECT * FROM A;
If you can't just recreate your table, use the ALTER TABLE syntax:
ALTER TABLE "A" RENAME TO a;
