SELECT items.* FROM invoice JOIN items ON invoice.id = items.invoiceid WHERE amount > 1000 OR taxFree = true 这条SQL语句的作用是什么？

这条SQL语句的作用是从一个名为invoice的表中获取所有满足以下条件的items：

与invoice表关联的items，通过invoice.id = items.invoiceid连接
金额大于1000
免税(taxFree)为true

换句话说，它将返回所有在发票中有超过1000金额的免税商品。

帮我把这段SQL从(+)写法修改为left join写法: SELECT temp.segment8, aia.* FROM ap_invoices_all aia, (SELECT aid.invoice_id, gcc.segment8, row_number() over(PARTITION BY aid.invoice_id, gcc.segment8 ORDER BY aid.invoice_id) row_num FROM ap_invoice_distributions_all aid, gl_code_combinations gcc WHERE gcc.code_combination_id = aid.dist_code_combination_id) temp WHERE aia.invoice_num = 'CBS202305041001' AND aia.invoice_id = temp.invoice_id(+) AND temp.row_num(+) = 1

当将(+)写法修改为left join写法时，我们需要将原始查询中的两个关联条件进行修改。下面是修改后的SQL查询：
SELECT temp.segment8, aia.*
FROM ap_invoices_all aia
LEFT JOIN
(SELECT aid.invoice_id,
gcc.segment8,
row_number() over(PARTITION BY aid.invoice_id, gcc.segment8 ORDER BY aid.invoice_id) row_num
FROM ap_invoice_distributions_all aid
INNER JOIN gl_code_combinations gcc ON gcc.code_combination_id = aid.dist_code_combination_id) temp
ON aia.invoice_id = temp.invoice_id AND temp.row_num = 1
WHERE aia.invoice_num = 'CBS202305041001'

需要的类型: InvoiceWhiteTitleModel 提供的类型: List <com.nurseh.meet.front.invoice.model.InvoiceOrderModel>

InvoiceWhiteTitleModel并不是您提供的列表类型 <com.nurseh.meet.front.invoice.model.InvoiceOrderModel> 的直接成员。然而，如果InvoiceOrderModel是您的订单模型，而InvoiceWhiteTitleModel是你需要从这些订单模型中提取特定信息的一个子模型或者是某种筛选后的结果，那么可能需要通过遍历列表来查找匹配InvoiceWhiteTitleModel定义的数据。
例如，假设InvoiceOrderModel有一个whiteTitles字段，它包含了标题信息，你可以这样做：
// 假设发票订单列表不为空
List<InvoiceOrderModel> invoiceOrders = ...;
List<InvoiceWhiteTitleModel> whiteTitleModels = new ArrayList<>();
for (InvoiceOrderModel order : invoiceOrders) {
List<String> titles = order.getWhiteTitles(); // 假设存在getWhiteTitles方法获取标题列表
for (String title : titles) {
InvoiceWhiteTitleModel whiteTitle = new InvoiceWhiteTitleModel(title); // 创建新模型并设置标题
whiteTitleModels.add(whiteTitle);
}
}

这会创建一个新的InvoiceWhiteTitleModel列表，其中包含了原始invoiceOrders中的每个订单的白色标题。
