Question

我应该在xampp中执行此操作，为此需要一个sp结构，因为如果可能，我是一个初学者，可以通过详细说明为该方案提供完整的sp。诸如crud操作之类的其他结构已使用php，javascript

完成

1. SELECT `cid`, `parent_cat`, `category_name`, `category_life`, `status` FROM `categories`
2. SELECT `pid`, `cid`, `bid`, `product_name`, `product_price`, `product_stock`, `added_date`, `p_status`, `loc`, `in_no`, `gst_no`, `cgst`, `sgst`, `igst`, `total`, `depre`, `pur_from` FROM `products`

从上面两个表的i中，我应该获取记录并计算这些字段并插入下表中：

3. SELECT `elapsed_yend`, `remaining_days`, `depreciation_cur`, `current_wdv`, `depreciation_next`, `next_wdv`, `accumulate_depre`, `sale_amount`, `pro_los`, `end_date` FROM `calculation`

例如，这些计算应在产品表中进行：

CGST:
    cgst = product_price * 09
    sgst = product_price * 09
    igst = product_price * 09

if status is 1 it should calculate  igst other cgst,sgst must be 0(zero)
             0 it should calculate  cgst,sgst other igst  must be 0(zero)

        Depreciation Amount:

            depre = product_price + .5(cgst+sgst+igst)


Elapsede year end :
        elapsed_yend = added_date(from products table (No:2)) till every year 31/March/xxxx.

        Number of days between these two dates

    remaining_days = category_life - (date difference between added_date(from products (No:1)) till date)

    category_life(from categories table (No:1))Ex:mobile it's life will be 1080 days.

    Current Year depreciation:
        depreciation_cur  = (depre/category_life)*elapsed_yend

    Current Year Written down value:

        current_wdv  = depre - depreciation_cur

    Next Year depreciation :

        depreciation_next = (depre / category_life) * D
        D = days difference between every year 01/April/xxxx till end_date(from calculation table)

    Next Year Written down value:   

        next_wdv = current_wdv - depreciation_next

    Accumulate Depreciation :

        accumulate_depre = depreciation_cur + depreciation_next

如果需要，请提出一些建议以改进我的存储过程。无论如何，我已经破解了它，到目前为止它运行良好。非常感谢所有支持，尤其是堆栈溢出团队

UPDATE calc SET pro_loss = 0 WHERE sale_status=0;
SELECT * from calc;

END

需要存储过程才能从这两个表中进行计算
