getObjectValue
Description copied from class:ObjectResultSet
Primary method for subclass to override to retrieve a value.The signature does not constrain this to return an object of the requested class, so it can still be used as before by methods that may do additional coercions. When called by
ObjectResultSet.getObject(int,Class)
, that caller enforces the class of the result.- Specified by:
getObjectValue
in classObjectResultSet
- Throws:
SQLException
-
getConcurrency
ReturnsResultSet.CONCUR_READ_ONLY
.- Specified by:
getConcurrency
in interfaceResultSet
- Overrides:
getConcurrency
in classSingleRowResultSet
- Throws:
SQLException
-
cancelRowUpdates
