- パラメータ:
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 benull
if Query.QUERY_NO_METADATA was specified.tuples
- the actual datacursor
- a cursor to use to fetch additional data;null
if no further results are present.

- パラメータ:
status
- the command status string (e.g. "SELECT") returned by the backendupdateCount
- the number of rows affected by an INSERT, UPDATE, DELETE, FETCH, or MOVE command; -1 if not available.insertOID

secureProgress
public void secureProgress()インタフェースからコピーされた説明:ResultHandler
Callback for batch statements. In case batch statement is executed in autocommit==true mode, the executor might commit "as it this it is best", so the result handler should track which statements are executed successfully and which are not.- 定義:

- パラメータ:
warning
- the warning that occurred.

handleError
インタフェースからコピーされた説明: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.- 定義:

- オーバーライド:
handleError

- パラメータ:
newError
- the error that occurred

handleCompletion
インタフェースからコピーされた説明: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.- 定義:
handleCompletion
インタフェース内ResultHandler
- オーバーライド:
handleCompletion
クラス内ResultHandlerBase
- 例外:
SQLException
- if the handler wishes the original method to throw an exception.
