oracle BBDDで関数を返す行の数を数えようとしています。私は他のいくつかの質問（例えば：rs.last() gives Invalid operation for forward only resultset : last）に見てきましたが、それはResultSet.TYPE_SCROLL_INSENSITIVE、ResultSet.CONCUR_READ_ONLY〜callablestatementに追加する必要があります。resultset.last（）はJavaで例外をスローします
私は結果なし... ResultSet.TYPE_SCROLL_INSENSITIVE、またResultSet.TYPE_SCROLL_SENSITIVEを試してみました。私はまだ同じ無効な操作の例外が発生します。
私が紛失していることはありますか？
HERESに私のコード：
String call = "{ ? = call MyProcedure (?) }";
CallableStatement cstmt= conn.prepareCall(call, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
cstmt.setString(2,"param 1");
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
cstmt.execute();
ResultSet rset = (ResultSet)cstmt.getObject(1);
rset.last(); //Exception comes here
int rowsnumber = rset.getRow();
感謝。
編集：
create or replace FUNCTION MyProcedure
(IdC IN VARCHAR2
)
RETURN sys_refcursor
IS
c_result sys_refcursor;
BEGIN
OPEN c_result FOR SELECT name, properties FROM city WHERE name = IdC;
RETURN c_result;
END;
