HSQLDB user lacks privilege or object not found error when making select statements with where

问题

I use SQuirrel SQL Client Version 3.5.3 and HSQLDB for my database. I have been able to specify the corresponding driver (In-memory) to it and create an Alias.

I have created a table

CREATE TABLE ENTRY(
NAME VARCHAR(100) NOT NULL,
DESC VARCHAR(500) NOT NULL,
PRIMARY KEY (NAME))

and added a few lines of data into it. While statements like these work:

select * from ENTRY
select NAME from ENTRY
select DESC from ENTRY

I always get Error: user lacks privilege or object not found" when adding a where clause to my statement, e.g. select DESC from ENTRY where NAME=CAR

Any help is greatly appreciated as I can slowly feel my sanity waning

I had the same problem, but my table name and other things were ok except my query for VARCHAR were inside double quotes("") but it should be in single quotes('')

example:
assume you have table like this which flightId is primary key

now this query is wrong:

SELECT * FROM flights WHERE flightId="0f3ae9b3-6bb1-4c95-9394-6179555f5879"

while this one is ok:

SELECT * FROM flights WHERE flightId='0f3ae9b3-6bb1-4c95-9394-6179555f5879'

I was finally able to fix this myself. I had used a wrong table name for my select statements and after changing it to the real one it worked. The only thing that confuses me is that I also used the wrong table name for my insert statements but they were executed successfully and all data is showing up in them.

HSQLDB has default schema called PUBLIC. All SQL queries will be pointing to PUBLIC; If you have created your own schema like eg:OWNSCHEMA then edit the xxx.script and change the following line

SET DATABASE DEFAULT INITIAL SCHEMA PUBLIC

SET DATABASE DEFAULT INITIAL SCHEMA OWNSCHEMA

When I received the same exception the root cause was that I had a table in the SELECT clause that was not present in the FROM clause.
