!ISNULL((DT_DATE)last_local_call_time) ? last_local_call_time : "Null"

but getting this Error;

[OLE DB Destination [16]] Error: SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80040E21.
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80040E21  Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".

kindly help .

Answer 1

Can't you get it as datetime from the source instead of a srtring? Then you have less problems with the format of the datatime...

Or if you don't want a datetime format use:
!ISNULL(last_local_call_time) ? last_local_call_time : "Null"
