Hi Eswar,
I am not that sure with the function support of Castor ATM but we plan a
big refactoring of the OQL engine for 1.1 release.
Until that time I suggest you one of 2 workarounds:
1. Use SQL passthrough queries like:
CALL SQL select ... from ... where AS <classname>
Please take care that the number and sequence of the select columns
are similar to those of a OQL query for the requested class.
2. Create a view that offers the columns that include function calls:
select *, CONCAT(TO_CHAR(qtr_year),TO_CHAR(quarter)) as YEAR_QTY
from mpmweb.mpm_coding
Use this view in the castor mapping.
Hope that helps.

Hi,
I am sure Castor supports the “functions” like TO_CHAR(), CONCAT() etc..
But I am not able to use it properly , can anybody suggest one example .
*SQL:*
* *
SELECT distinct(metric_name)
FROM mpmweb.mpm_coding
WHERE market_name = 'SCORECARD'
AND CONCAT(TO_CHAR(qtr_year),TO_CHAR(quarter)) BETWEEN
CONCAT(TO_CHAR(2004),TO_CHAR(3)) AND CONCAT(TO_CHAR(2005),TO_CHAR(1));
*OQL:*
* *
*aQuery = db.getOQLQuery(" SELECT metricList FROM
com.cummins.mpm.domain.MeasurementWeightList metricList "*
* + " WHERE metricList.marketName =
$1 AND metricList.metricName != $4 AND
concat(to_char(metricList.quarter),to_char(metricList.quarterYear))
between $2 AND $3 ");*
aQuery.bind(marketName.trim());
aQuery.bind(fromQtrYear);
aQuery.bind(toQtrYear);
aQuery.bind(pbit);
Any help really appreciated !!!
