Method Detail

handleResultRows

public void handleResultRows(Query fromQuery,
                             Field[] fields,
                             List<byte[][]> tuples,
                             ResultCursor cursor)

Description copied from interface: ResultHandler

Called when result rows are received from a query.

Specified by:

handleResultRows in interface ResultHandler

Parameters:

fromQuery - the underlying query that generated these results; this may not be very specific (e.g. it may be a query that includes multiple statements).

fields - column metadata for the resultset; might be null if Query.QUERY_NO_METADATA was specified.

tuples - the actual data

cursor - a cursor to use to fetch additional data; null if no further results are present.

handleCommandStatus

public void handleCommandStatus(String status,
                                int updateCount,
                                long insertOID)

Description copied from interface: ResultHandler

Called when a query that did not return a resultset completes.

Specified by:

handleCommandStatus in interface ResultHandler

Parameters:

status - the command status string (e.g. "SELECT") returned by the backend

updateCount - the number of rows affected by an INSERT, UPDATE, DELETE, FETCH, or MOVE command; -1 if not available.

insertOID - for a single-row INSERT query, the OID of the newly inserted row; 0 if not available.

secureProgress

public void secureProgress()

handleWarning

public void handleWarning(SQLWarning warning)

Description copied from interface: ResultHandler

Called when a warning is emitted.

Specified by:

handleWarning in interface ResultHandler

Parameters:

warning - the warning that occurred.

handleError

public void handleError(SQLException newError)

Description copied from interface: ResultHandler

Called when an error occurs. Subsequent queries are abandoned; in general the only calls between a handleError call and a subsequent handleCompletion call are handleError or handleWarning.

Specified by:

handleError in interface ResultHandler

Parameters:

newError - the error that occurred

handleCompletion

public void handleCompletion()
                      throws SQLException

Description copied from interface: ResultHandler

Called before a QueryExecutor method returns. This method may throw a SQLException if desired; if it does, the QueryExecutor method will propagate that exception to the original caller.

Specified by:

handleCompletion in interface ResultHandler

Throws:

SQLException - if the handler wishes the original method to throw an exception.

getGeneratedKeys

public ResultSet getGeneratedKeys()
