> Key: TORQUE-123
> URL: https://issues.apache.org/jira/browse/TORQUE-123
> Project: Torque
> Issue Type: Bug
> Components: Village
> Affects Versions: 3.3
> Environment: OS ：RedHat Enterprise Linux ES 4 update 4
> Java ：1.4.2_08
> Tomcat：4.1.31
> Torque：3.0.2
> JDBC(Oracle): ojdbc.jar(10.2.0.4)
> Reporter: Kazu Nambo
> Assignee: Thomas Fischer
> Fix For: 3.3.1
>
>
> When syntax error(SQLException) happens at executeQuery in the constructor
> QueryDataSet(Connection conn, String selectStmt), the member stmt is left
> open and this problem sometimes results in ORA-01000 (Maximum open cursors
> exceeded).
> In the upper layer like BasePeer#executeQuery method, it tries to close
> QueryDataSet instance by VillageUtils.close but it fails because the instance
> is null.
> Other exceptions may result in the same situation.
> If I try to make the constructor more robust as follows, it will work. (No
> ORA-01000)
> public QueryDataSet(Connection conn, String selectStmt)
> throws SQLException, DataSetException
> {
> this.conn = conn;
> selectString = new StringBuffer(selectStmt);
> try
> {
> stmt = conn.createStatement();
> resultSet = stmt.executeQuery(selectStmt);
> schema = new Schema();
> schema.populate(resultSet.getMetaData(), null);
> }
> catch (Exception e)
> {
> try {
> if (null != resultSet) {
> resultSet.close();
> }
> } catch (Exception ignored) {}
> try {
> if (null != stmt) {
> stmt.close();
> }
> } catch (Exception ignored) {}
> if (e instanceof SQLException)
> throw (SQLException)e;
> else if (e instanceof DataSetException)
> throw (DataSetException)e;
> else
> throw new SQLException("QueryDataSet: exception
> caught.", e);
> }
> }
