I created two tables that match the names and columns of your query and it
works. The table creation DDL is as follows:
CREATE TABLE "groupmembership"("user" INTEGER, "group" INTEGER);
CREATE TABLE "groupcapability"("group" INTEGER, "capability" INTEGER);
It is obvious that one or both the tables were not defined with quoted
names, in which case their names would be interpreted by any SQL92 compliant
DB as all uppercase and would not match the quoted lowercase names.
Try:
SELECT * FROM groupmembership WHERE "user" = 1 AND EXISTS ( SELECT
groupcapability."group" FROM groupcapability, "groupmembership" WHERE
groupcapability."group" = groupmembership."group" AND "capability" = 0)
If you want to see the exact DDL as interpreted by HSQLDB, run
DatabaseManager, open the database, and issue the SCRIPT command. All
unquoted names will be unquoted in uppercase and all quoted names will be
quoted as they were defined.

Subject: [Hsqldb-developers] Quoting problem
Hi Fred,
Here is another little one, I have quoted everything and come up with this
SELECT * FROM "groupmembership" WHERE "user" = 1 AND EXISTS ( SELECT
"groupcapability"."group" FROM "groupcapability", "groupmembership" WHERE
"groupcapability"."group" = "groupmembership"."group" AND "capability" = 0)
Error reported by jdbc driver
Column not found: S0022 Column not found: group in statement [SELECT * FROM
"groupmembership" WHERE "user" = 1 AND EXISTS ( SELECT
"groupcapability"."group" FROM "groupcapability", "groupmembership" WHERE
"groupcapability"."group" = "groupmembership"."group" AND "capability" = 0)]
Is there an obvious way around this problem?
cheers
