advance="no"

抱歉，我之前的回答中的 'advance="no"' 是一个错误，我犯了一个错误。在Fortran中，'advance="no"' 并不是有效的写法。这是我错误地将Fortran的格式控制语句与输入语句混淆了。

在Fortran中，'advance="no"' 是无效的。正确的用法是使用非格式化的输入语句，例如：

write(*, *) "Enter the size of the array:"
read(*, *) size

这样可以在屏幕上输出提示信息 "Enter the size of the array:"，然后从用户输入读取值并将其存储在变量 size 中。

非格式化的输入语句中的 * 号表示标准输入/输出单元，也就是通常用于终端输入和输出的设备。您可以根据需要更改它。

再次对之前的错误表示歉意，并感谢您的指正。如果您还有其他问题，请随时提问！

首先，我们可以对该 SQL 查询语句进行简化，只选择需要的字段而不是全部选择。其次，我们可以尝试添加索引以加快查询速度。

以下是优化后的 SQL 查询语句：

SELECT pao.id, pao.order_no, pao.apply_time, pao.purchase_user_id, pao.purchase_user_name, pao.apply_user_id, 
       pao.apply_user_name, pao.apply_department_id, pao.apply_department_name, pao.apply_end_time, pao.create_user_id, 
       pao.create_user_name, pao.approve_type, pao.approve_user_id, pao.approve_user_name, pao.approve_time, 
       pao.description, pao.order_type, pao.purchase_type, pao.storage_type, pao.compose_order_no, pao.company_id, 
       pao.delete, pao.create_time, pao.update_time, pao.supplier_id, pao.image_path, pao.contract_id, pao.status, 
       pao.invoice_signer_name, pao.total_amount, pao.total_amount_tax, pao.purchase_status, pao.cancel_reason, 
       pao.print_status, pao.demand_id, pao.arrival_status, pao.supervise_num, pao.supervise_date, pao.merge_apply_id, 
       pao.deadline, pao.remind, s.name AS supplierName, paod.amount, cm.return_status AS returnStatus, 
       cm.inventory_status AS inventoryStatus, cm.stock_remark, cm.merge_flag, cm.signature_file, cm.department_pass, 
       cm.receipt_file, cm.amount_paid, cm.amount_unpaid, cm.contract_name, cm.status AS contractStatus, 
       cm.contract_no, cm.contract_amount, paod.product_name, cm.advance_payment, cm.advance_ratio, cm.currency_unit
FROM purchase_apply_order pao 
LEFT JOIN supplier s ON pao.supplier_id = s.id 
LEFT JOIN (
    SELECT GROUP_CONCAT(DISTINCT p.product_name) product_name, SUM(IFNULL(amount_tax, 0)) amount, apply_order_no 
    FROM purchase_apply_order_details pa 
    LEFT JOIN product p ON p.pn_code = pa.product_code 
    WHERE p.company_id = 29 
    GROUP BY apply_order_no 
) paod ON paod.apply_order_no = pao.order_no 
LEFT JOIN contract_management cm ON pao.contract_id = cm.id 
WHERE pao.delete = 0 
  AND pao.company_id = 29 
  AND deadline <= '2023-05-25 15:34:00.01' 
  AND remind = 0 
  AND arrival_status IN (0, 1) 
ORDER BY pao.create_time DESC;

我们可以为 `purchase_apply_order` 表的 `company_id` 字段和 `deadline` 字段以及 `remind` 字段创建索引。同时，也可以为 `arrival_status` 字段和 `delete` 字段创建索引。这可以大大加快查询速度。

CREATE INDEX idx_purchase_apply_order_company_id_deadline_remind ON purchase_apply_order (company_id, deadline, remind);

CREATE INDEX idx_purchase_apply_order_arrival_status_delete ON purchase_apply_order (arrival_status, delete);

fortran里面格式如何从横排换成竖排

在Fortran中，可以使用FORMAT语句来控制输出格式。要将输出从横排转换为竖排，可以使用以下步骤：

1. 将要输出的数据存储在一个数组中。
2. 在FORMAT语句中使用/符号表示换行。
3. 在DO循环中逐行输出数据。

以下是示例代码：

PROGRAM vertical_output
IMPLICIT NONE
INTEGER :: i
REAL :: data(5)

data = [1.0, 2.0, 3.0, 4.0, 5.0]

WRITE(*, '(A)', ADVANCE='NO') 'Data:'
DO i = 1, 5
   WRITE(*, '(F5.1)', ADVANCE='NO') data(i)
   WRITE(*, '(A)', ADVANCE='YES') ''
END DO

END PROGRAM vertical_output

在上面的代码中，我们使用DO循环逐行输出数据，并在每行结尾处使用空的FORMAT语句来实现换行。输出结果如下：

Data:
 1.0
 2.0
 3.0
 4.0
 5.0
