SingleRowWriter
public SingleRowWriter(TupleDesc tupleDesc)
throws java.sql.SQLException
- Throws:
java.sql.SQLException
getObjectValue
protected java.lang.Object getObjectValue(int columnIndex)
throws java.sql.SQLException
- Specified by:
getObjectValue
in class ObjectResultSet
- Throws:
java.sql.SQLException
rowUpdated
public boolean rowUpdated()
throws java.sql.SQLException
- Returns
true
if the row contains any non null
values since all values of the row are null
initially.
- Throws:
java.sql.SQLException
updateObject
public void updateObject(int columnIndex,
java.lang.Object x)
throws java.sql.SQLException
- Throws:
java.sql.SQLException
cancelRowUpdates
public void cancelRowUpdates()
throws java.sql.SQLException
- Throws:
java.sql.SQLException
close
public void close()
throws java.sql.SQLException
- Cancels all changes but doesn't really close the set.
- Throws:
java.sql.SQLException
copyRowFrom
public void copyRowFrom(java.sql.ResultSet rs)
throws java.sql.SQLException
- Throws:
java.sql.SQLException
getTupleAndClear
public long getTupleAndClear()
throws java.sql.SQLException
- Creates a tuple from the current row values and then cancel all row
updates to prepare for a new row. This method is called automatically by
the trigger handler and should not be called in any other way.
- Returns:
- The native pointer of the Tuple reflecting the current row
values.
- Throws:
java.sql.SQLException
getTupleDesc
protected final TupleDesc getTupleDesc()
- Specified by:
getTupleDesc
in class SingleRowResultSet
isClosed
public boolean isClosed()
throws java.sql.SQLException
- Throws:
java.sql.SQLException
getHoldability
public int getHoldability()
- Returns
ResultSet.CLOSE_CURSORS_AT_COMMIT
. Cursors
are actually closed when a function returns to SQL.
- Specified by:
getHoldability
in interface java.sql.ResultSet
- Overrides:
getHoldability
in class SingleRowResultSet
