I have following table in my QV documnet, In my data load script I have created the field 'POLICY_PERIOD'combining the two fields 'POL_PERIOD_FROM' and 'POL_PERIOD_TO' with following syntax.
DUAL( DATE(POL_PERIOD_FROM,'MMM-YY') &' - '& DATE(POL_PERIOD_TO,'MMM-YY'),POL_PERIOD_FROM) AS POLICY_PERIOD,
However in the policy period column ending period shown as Mar-17 although actual ending period is Sep-16. I can not understand how that happened and kindly correct me if I have done anything wrong,
Solved! Go to Solution.
I think I know what the problem is. A dual value can only have one possible text representation for a numerical value. The real value of the dual is the numeric - the text is only the display representation of the value.
I expect that you have a POLICY_PERIOD value somewhere else for POL_PERIOD_FROM = 31 March (Mar-16 - Mar-27). In the model, the dual will be stored as a numeric with a single display format. So the display value for 31 March 2016 is the value in POLICY_PERIOD.
If you want to correctly reflect you would have to create a numeric value that considers both the _FROM and _TO fields. You could try this if you want to return a valid date value that reflects the FROM date:
Dual(Date(POL_PERIOD_FROM, 'MMM-YY') & ' - ' & Date(POL_PERIOD_TO, 'MMM-YY'),
POL_PERIOD_FROM + POL_PERIOD_TO/100000
) as POLICY_PERIOD,
It looked like an unexplainable bug ... and doing the same within the UI worked like expected. I think I would re-create the qvd-source and ensure that the from/to-fields there are loaded equally maybe with floor(to).
