"operation not allowed for temporary LOBs"
*Cause: Temporary LOB locators are not allowed in the operation.
OCILobAssign only takes persistent LOB locators as parameters,
not temporary LOBs.
*Action: Use OCILobLocatorAssign for temporary LOBs instead.
Note that OCILobLocatorAssign can also be used for persistent
LOBs, in which case it will behave the same as OCILobAssign.
