Question

我对ScrollableCursor有问题。在我的本地环境中，它运行良好，但是在远程环境中，我遇到了异常：

内部异常：java.sql.SQLException：结果集已关闭。错误代码：0 在org.eclipse.persistence.exceptions.DatabaseException.sqlException（DatabaseException.java:340）在org.eclipse.persistence.internal.databaseaccess.DatabaseAccessor.processExceptionForCommError（DatabaseAccessor.java:1620）在org.eclipse.persistence.queries.ScrollableCursor.getPosition（ScrollableCursor.java:251）在org.eclipse.persistence.queries.ScrollableCursor.retrieveNextObject（ScrollableCursor.java:551）在org.eclipse.persistence.queries.ScrollableCursor.loadNext（ScrollableCursor.java:411）在org.eclipse.persistence.queries.ScrollableCursor.hasNext（ScrollableCursor.java:277）

我的查询：

SELECT 
    order_header.order_head_id,
    order_header.order_date,
    order_header.status,
    suppliers.supplier,
    categories.category,
    order_header.user,
    order_header.sage_ref,
    SUM(order_lines.total_price) AS price
FROM
    order_header
        LEFT JOIN
    order_lines ON order_header.order_head_id = order_lines.order_head_id
        LEFT JOIN
    suppliers ON order_header.supplier_id = suppliers.supp_id
        LEFT JOIN
    categories ON order_header.category = categories.cat_id
WHERE
    order_header.status LIKE '%'
        AND order_header.order_head_id LIKE '%'
        AND order_header.user LIKE '%'
GROUP BY order_header.order_head_id
ORDER BY order_head_id DESC
LIMIT 50;

能否请您告诉我一些错误的地方？
