Select query on key field for different time format

Hello Experts,

I am working in Sender ABAP proxy <===> SAP PI 7.31 JAVA <===> Oracle database.

Oracle Database stores all records of material sold where the date is maintained in 01/15/2010 01:48:20 which has date and time format.

In ECC , I will be sending a proxy request with system date as the only field and this would be key field to select all the material records sold for 01/15/2010 in Oracle Database i.e. Select statement.As we can observe that the system data of ECC does not have time stamp.

I am clueless how to get this done in Message Mapping or in some way? If I maintain just the date stamp of ECC as the key field, would I be

able to fetch all the records from Database?

Regards

Rebecca
