Hi Frank,
Qualifying column names with the esq schema does not affect my results.
The following script runs fine for me:
connect 'jdbc:derby:memory:db;create=true';
create schema esq;
set schema esq;
create table attachment( guid int, file_name varchar( 10 ) );
create index ATTACHMENT_LINKNAMES_INDEX on attachment( guid, file_name );
SELECT
esq.attachment.guid, esq.attachment.file_name
FROM
esq.attachment
--DERBY-PROPERTIES index = ATTACHMENT_LINKNAMES_INDEX
;
Hope this helps,
-Rick

Will do.
We implicitly use the schema “*esq*” (not the the name matters) in all
column names and in the from clause e.g. “FROM *esq.*attachment”. Can
you try it this way just to be sure I’m not crazy. We also use the
schema when creating the index on the table. BTW 10.10.1.1 is what we
are using. I see I typed it wrong in last email.

Hi Frank,
I am unable to reproduce the problem you are seeing when I run the
following script using Derby 10.10.1.1:
connect 'jdbc:derby:memory:db;create=true';
create table attachment( guid int, file_name varchar( 10 ) );
create index ATTACHMENT_LINKNAMES_INDEX on attachment( guid, file_name );
SELECT
attachment.guid, attachment.file_name
FROM
attachment
--DERBY-PROPERTIES index = ATTACHMENT_LINKNAMES_INDEX
;
The error message you're seeing is raised by the parser. I have
extracted the relevant method from the 10.10.2.0 parser into the
attached zzz.java program. I am unable to reproduce the problem
you're seeing when I run that program on your text. Try setting the
PROPS field in that program equal to what follows
"--DERBY-PROPERTIES" in your query and see if you can tickle the
program into failing.
Hope this helps,

We have a simple query using LIKE but is very slow.
We need to tell the optimizer which index to use but the override
DERBY-PROPERTIES statement returns the following error.
*Invalid syntax for optimizer overrides. *The syntax should be --

Here is the SQL. The index does exist.
