我试图使用T-SQL查询来实现此结果

Question

在下表中，根据说明，我们在不同的列中有不同的数量。我们希望使用T-SQL脚本将所有数量放在一列中，而将desc放在另一列中。表名是rawdata。

当前表格结果：

SSI_CUST_TRANS#  WAYBILL#   BILL_OF_LADING  NET_FREIGHT_CHARGES MISC_CODE1_DESC MISC_CODE1_AMT  MISC_CODE2_DESC MISC_CODE2_AMT  MISC_CODE3_DESC MISC_CODE3_AMT  MISC_CODE4_DESC MISC_CODE4_AMT
3574296 618852  618852  32.5    SPECIAL DELIVERY    40  FUEL SURCHARGE  4.88    NULL    NULL    NULL    NULL
3574319 618852  618852  32.5    SPECIAL DELIVERY    40  FUEL SURCHARGE  4.88    NULL    NULL    NULL    NULL

必填结果：

 BILL_OF_LADING WAYBILL#    SSI_CUST_TRANS# Charge Type Desc    Amount
618852  618852  3574296 AMOUNT_PAID     77.38
618852  618852  3574296 NET_FREIGHT_CHARGES ELECTRONIC EQUIP./PARTS 32.5
618852  618852  3574296 SPECIAL DELIVERY        40
618852  618852  3574296 FUEL SURCHARGE      4.88
618852  618852  3574319 AMOUNT_PAID     0
618852  618852  3574319 NET_FREIGHT_CHARGES ELECTRONIC EQUIP./PARTS 32.5
618852  618852  3574319 SPECIAL DELIVERY        40
618852  618852  3574319 FUEL SURCHARGE      4.88

我们希望数量和描述如图所示进行转置。

从上面的数据尝试这样的 预期输出需要更多数据

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id="one_to_many">click
<form action="demo_form.asp">
      <input type="checkbox" name="graph" value="like"> کامنت ها<br>
      <input type="checkbox" name="graph" value="comment" checked> لایک ها<br>
      <input type="checkbox" name="graph" value="friend" checked> دوستان<br>
      <input type="button" id="cls_btn" value="رسم گراف">
     </form>
</div>

输出
