Subject --DERBY-PROPERTIES throws error
Date Fri, 11 Apr 2014 16:33:20 GMT

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 -- DERBY-PROPERTIES propertyName
= value [, propertyName = value]*

Here is the SQL. The index does exist.

SELECT 
esq.attachment.guid, esq.attachment.file_name 
FROM 
esq.attachment 
--DERBY-PROPERTIES index = ATTACHMENT_LINKNAMES_INDEX
where 
(   
 	esq.attachment.file_name  LIKE ‘%drisco%' 
   OR esq.attachment.file_index_name  LIKE ‘%drisco%' 
)
AND
(
        esq.attachment.link_guid IS NOT NULL 
        AND 
        esq.attachment.link_table='mat'  
        AND 
        esq.attachment.link_guid IN (
                SELECT esq.matter.guid 
                FROM esq.matter 
                WHERE 
                esq.matter.guid=esq.attachment.link_guid 
                AND ( 
				( esq.matter.grp_guid=0 OR esq.matter.grp_guid IS NULL ) OR ( esq.matter.grp_guid>0
AND esq.matter.grp_guid IN ( 2,1,6,4,3 ) ) 
			)   
                        
        )
) ;
