Hey Brian,
I checked out the wengine-branch filemgr and unfortunately, it still didn't
work. I tried a query using the wengine branch's query_tool since this version
of the filemgr-client didn't have the ability to query.
In any case, I took the liberty of diving into the Query Tool code to see if I
can find out more as to what is going on. So this is what I found:
Surrounding single quotes around each of the conditions got me further into the
code. So, when I entered the query as follows,
SELECT * FROM L0a_Radar WHERE 'RangeBeginningDate>2007-01-01' AND
'RangeBeginningTime>12:00:00Z'
The SQLParser class liked the syntax and it produced the following post fix
statement:
Post Fix Statement: ['RangeBeginningDate>2007-01-01',
'RangeBeginningTime>12:00:00Z', AND]
I think from here, it creates some Boolean Query Criteria with the following
content:
Boolean Query Criteria: AND('RangeBeginningTime:[12:00:00Z' TO null],
'RangeBeginningDate:[2007-01-01' TO null])
I noticed that there are unmatched single quotes around the date and time
values. Not sure how that came about. The tool still threw an exception. I'm
guessing it's because of the unmatched single quotes.
I tried surrounding the date and time values with single quotes as well, but
the SQLParser class didn't like that either:
SELECT * FROM L0a_Radar WHERE 'RangeBeginningDate>'2007-01-01'' AND
'RangeBeginningTime>'12:00:00Z''

hey mike,
would you mind trying to run this query using the wengine-branch filemgr
(https://svn.apache.org/repos/asf/oodt/branches/wengine-branch/filemgr/)...
there are a lot of bug fixes floating around in both Lucene and DataSource
Catalogs in that branch... if it works with that then we know it is a bug with
trunk.

Hey Brian,
Ya, I tried the query with and without the double quotes surrounding the where
clause and they both didn't work for me.
In any case, I've built the latest file manager in the trunk and it fixed that
StringIndexOutofBoundsException issue I was seeing. Thanks!
Out of curiosity, I tried using the latest File Manager Client tool with the
query with multiple conditions to see if I could get a result, but it threw an
exception as well:
./filemgr-client -u http://localhost:9000 -q "SELECT * FROM L0a_Radar WHERE
RangeBeginningDate>'2007-01-01' AND RangeBeginningTime>'12:00:00Z'" -op

hey mike,
first pass over the policy files look good... however, is the way you posted
the query the way you are running it?
./query_tool --url http://localhost:9000<http://localhost:9000/> --sql -query
"SELECT * FROM L0a_Radar WHERE "RangeBeginningDate>'2007-01-01' AND
RangeBeginningTime>'12:00:00.000Z'""
you have an extra set of double quotes around the where clause... try removing
those

My repository manager and catalog combination is defined as follows in the
filemgr.properties:
filemgr.repository.factory=org.apache.oodt.cas.filemgr.repository.XMLReposi
toryManagerFactory
filemgr.catalog.factory=org.apache.oodt.cas.filemgr.catalog.DataSourceCatal
ogFactory
org.apache.oodt.cas.filemgr.catalog.datasource.quoteFields=true

Based on the properties specified above, the quoteFields option is turned
on. So I think the properties are set correctly, no?
It'll be interesting to see if Brian was able to find an error in the
policy files that I sent in the previous e-mail.
