thr问题是，虽然它应该从linq中的临时表中返回行，但它返回一个int是否有任何理由说明为什么会发生这种情况？
答案 0 :(得分：3)
一个常见的原因是存储过程具有众所周知的弱元数据，特别是对于具有分支等的复杂代码。外部代码很难真正理解正在选择/返回的内容。
一个常见的技巧是用一些令人头脑麻木的简单（即简单地返回所需模式的任何样本数据）替换sproc用于检查过程，然后交换回真实代码。或者，如果可能，请考虑交换到UDF - 因为UDF具有更强大的模式元数据。
当然，您也可以根据类似的方法手动编辑DBML。
暂时不谈 - 您可能在现有代码中遇到许多问题，包括（但不限于）DML / DDL转换（强制重新编译），对同一个表进行多次更新（强制选择性重新编译） - 更不用说了游标用法（可能没有必要）。表变量（@table而不是#table）也可能有用。我不是要重写它;请注意一些您可能想要查看的内容。
答案 1 :(得分：-1)
SPROC中的第一个SELECT是在临时变量
中产生INTSELECT @CONTRACT = CONTRACT FROM [tbl_property] WHERE [PROPREF] = @PROPREF
这是绊倒元数据的原因。你应该做一个
SET @CONTRACT = (SELECT CONTRACT FROM [tbl_property] WHERE [PROPREF] = @PROPREF)
代替。
