如何以表格格式从另一个存储过程从存储过程获取输出值

Question

我有一个包含以下数据的表，该数据具有itemID和Imagepath （s）

tableImagePath

ItemID     frontimage                          backimage
---------  ----------------------------------  ---------------------------------
772740509  2011\11\24\1\8014681_5_1_FRONT.tif  2011\11\24\1\8014681_5_1_BACK.tif
772740508  2011\11\24\1\8014680_4_1_FRONT.tif  2011\11\24\1\8014680_4_1_BACK.tif
772740507  2011\11\24\1\8014679_3_1_FRONT.tif  2011\11\24\1\8014679_3_1_BACK.tif
772740506  2011\11\24\1\8014678_2_1_FRONT.tif  2011\11\24\1\8014678_2_1_BACK.tif
772740505  2011\11\24\1\8014677_1_1_FRONT.tif  2011\11\24\1\8014677_1_1_BACK.tif
772740504  2011\11\24\1\8014676_5_1_FRONT.tif  2011\11\24\1\8014676_5_1_BACK.tif
772740503  2011\11\24\1\8014675_4_1_FRONT.tif  2011\11\24\1\8014675_4_1_BACK.tif
772740502  2011\11\24\1\8014674_3_1_FRONT.tif  2011\11\24\1\8014674_3_1_BACK.tif
772740501  2011\11\24\1\8014673_2_1_FRONT.tif  2011\11\24\1\8014673_2_1_BACK.tif
772740500  2011\11\24\1\8014672_1_1_FRONT.tif  2011\11\24\1\8014672_1_1_BACK.tif

我已经存储了过程，该过程以base64编码生成图像的输出（来自上面的图像路径）。

declare @base64image as varchar(max)
exec dbo.prIMGCLR_ReadImage_Base64 '2011\11\24\1\8014681_5_1_FRONT.tif', @base64image out 
select @base64image

返回如下所示的输出：

SUkqAAgAAAATAP4ABAABAAAAKwIAAAIBAwABAAAAAQA+gAAABwBAwABAAAAAQAAACIAAAAAQAAAMgAAAABAAAA....

注意： dbo.prIMGCLR_ReadImage_Base64存储过程实际上已被锁定，我无法打开源来查看其内容。 因此，我只需要使用此过程，就没有其他函数可以返回以base64编码的值。

现在，如果我使用相同的过程来获取FrontImage和BackImage的base64编码值，则输出应如下所示：

tableImage_Base64Encoded

有人可以帮我解决这个问题吗？ 而不是循环遍历每个以产生结果。 有时，这可能会超过1000行。 这样一来，以表格形式生成输出可能要花费一些时间。 感谢您查看问题并提供解决方案。

如果无法将生成base64字符串的proc转换为标量值函数，恐怕您无能为力，只能遍历行并一次生成一个值
