nvl(t.valid_type,2)<>1

nvl(t.valid_type,2)是一个SQL语句中的函数，它的作用是判断字段t.valid_type的值是否为空，如果为空则返回2，否则返回t.valid_type的值。而<>1是一个条件判断，表示不等于1。所以整个表达式nvl(t.valid_type,2)<>1的含义是判断字段t.valid_type的值是否不等于1，如果不等于1则返回True，否则返回False。

首先，可以将子查询中的所有列名改为别名，这样可以避免重名和提高代码可读性。另外，可以尝试使用 EXISTS 子查询来替换 NOT EXISTS 子查询，因为 EXISTS 子查询的性能通常更好。最后，可以考虑对 WHERE 子句中的多个条件进行逻辑上的分组，以避免出现过于复杂的条件表达式。下面是优化后的 SQL：

我可以帮你将这段 SQL 转换成 Ignite 的写法，以下是转换后的代码：

IgniteCache<Object, Object> cache = ignite.getOrCreateCache("myCache");

SqlFieldsQuery query = new SqlFieldsQuery(
    "WITH t AS (" +
    "    SELECT NVL(t2.FINANCIER, t2.ISSUER) customerId, " +
    "        NVL(NVL(t1.TDY_FLOAT_INGPL, 0) + NVL(t1.DSC_COST_AMT, 0), 0) AS amount " +
    "    FROM PTL_SEC_VALUTION t1 " +
    "    INNER JOIN FIN_PRODUCT t2 ON t1.FINPROD_ID = t2.FINPROD_ID " +
    "    INNER JOIN FIN_PRODUCT_TYPE t3 ON t3.FINPROD_ID = t2.FINPROD_ID " +
    "    WHERE (t2.FINPROD_TYPE2 = 'F01' " +
    "        OR (t2.FINPROD_TYPE2 = 'F18' AND t3.TYPE_6 = 'P01' AND t3.TYPE_7 = '1209') " +
    "        OR (t2.FINPROD_TYPE2 = 'F18' AND t3.TYPE_6 = 'P11')) " +
    "        AND t1.CDATE = to_date(?, 'yyyy-MM-dd') - 1" +
    ") " +
    "SELECT h.counterId " +
    "FROM (" +
    "    SELECT n.counterId, n.amount " +
    "    FROM (" +
    "        SELECT m.counterId, sum(amount) amount " +
    "        FROM (" +
    "            SELECT t5.customer_Id counterId, T.AMOUNT " +
    "            FROM t " +
    "            INNER JOIN MST_CUSTOMER_INFO_ADD t5 ON t5.customer_id = t.customerId " +
    "            WHERE t5.INDUSTRY != '10' AND t5.PARENT_CUSTOMER_ID IS NULL " +
    "            UNION ALL " +
    "            SELECT t6.customer_Id counterId, T.AMOUNT " +
    "            FROM t " +
    "            INNER JOIN MST_CUSTOMER_INFO_ADD t5 ON t5.customer_id = t.customerId " +
    "            INNER JOIN MST_CUSTOMER_INFO_ADD t6 ON t6.customer_id = t5.PARENT_CUSTOMER_ID " +
    "            WHERE t5.INDUSTRY != '10'" +
    "        ) m " +
    "        GROUP BY m.counterId " +
    "    ) n " +
    "    ORDER BY n.amount DESC" +
    ") h " +
    "WHERE ROWNUM < 11"
);

query.setArgs(valDate);

try (QueryCursor<List<?>> cursor = cache.query(query)) {
    for (List<?> row : cursor) {
        Object counterId = row.get(0);
        // Do something with the counterId
    }
}

在上面的代码中，我们首先获取了一个 Ignite Cache 对象，然后创建了一个 `SqlFieldsQuery` 对象，将原来的 SQL 语句作为参数传递进去，并使用 `setArgs` 方法设置 SQL 语句中的参数值。最后，我们使用 `cache.query` 方法执行查询，并遍历结果集中的每一行数据，在其中获取 `counterId` 并做一些处理。
