Hi @GOLUSULAP16633731: Can you be more specific on the Question? Are you looking for created date and time for a specific case from PEGA or are you looking to get a list of all cases with its created date and time from DB?
If it is for a specific case, you can see it from the clipboard as mentioned by @KamineniSurya .
If you are looking for a list from table, try to find the table mapped for the case type class and you can use the pyID and pcCreateDateTime columns.
If accessing DB is not feasible, you can make use of API.
@GOLUSULAP16633731 : There will be an OOTB report definition 'DataTableEditorReport' created in your case type class. You can get all the work object details like case ID, case created time etc. from that report.
