The data can be used anywhere that you can use the return value of a user-d= efined function. It is possible that there are other contexts but I don't k= now what they are. Since the current effect of calling this method is that = Derby raises a coercion exception today, those use cases would be hidden be= hind coercion exceptions. >Is it read-only, or can it be modified? In the use cases I understand (function return values), the data is read-on= ly. >What is the life-time of the object? It depends on what the object is. If the object is a SQLClob (as in this pa= tch), then it is a transient, internal object which disappears at the end o= f the query. If, however, the object is the UserClob (a solution I am experimenting with= now), then the object's lifetime is determined by the application. >Does the data in the DVD (that implements getObject()) come from the user/= function or Derby? Or can it be both?=20 The data in the DVD comes out of the Clob returned by the user-defined func= tion. The function, of course, could have gotten the data from anywhere. > Calling functions that return Blob/Clob does not work. > ------------------------------------------------------ > > Key: DERBY-2201 > URL: https://issues.apache.org/jira/browse/DERBY-2201 > Project: Derby > Issue Type: Bug > Components: SQL > Affects Versions: 10.3.1.4 > Environment: Derby, head of trunk.

It fails because DataValueFactory.getClobDataValue= (Clob, StringDataValue) does not exist. However, getClobDataValue(String,= StringDataValue) exists.
