我有一张包含itemID和Imagepath（s）的以下数据的表
tableImagePath
ItemID frontimage backimage
--------- ---------------------------------- ---------------------------------
772740509 2011\11\24\1\8014681_5_1_FRONT.tif 2011\11\24\1\8014681_5_1_BACK.tif

772740501 2011\11\24\1\8014673_2_1_FRONT.tif 2011\11\24\1\8014673_2_1_BACK.tif

我有一个存储过程，用于生成base64编码的图像输出（来自上面的imagepath）。
declare @base64image as varchar(max)
exec dbo.prIMGCLR_ReadImage_Base64 '2011\11\24\1\8014681_5_1_FRONT.tif', @base64image out
select @base64image
返回输出，如下所示：
SUkqAAgAAAATAP4ABAABAAAAKwIAAAIBAwABAAAAAQA+gAAABwBAwABAAAAAQAAACIAAAAAQAAAMgAAAABAAAA....
注意：dbo.prIMGCLR_ReadImage_Base64存储过程实际上已被锁定，我无法打开源以查看其中的内容。
所以我只能使用这个过程，我没有其他函数返回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，输出应该如下所示......
tableImage_Base64Encoded

有人可以帮助我以良好的表现方式完成这项工作。而不是循环每一个以产生结果。 有时这可以超过1000行的项目。因此，以表格形式生成输出可能需要很长时间。 感谢您查看问题并为我提供解决方案。

如果你不能将产生base64字符串的proc转换为标量值函数，我恐怕除了迭代你的行并一次生成一个值之外你无能为力
