我想在外部關鍵約束條件下的SQL Server上創建一個表。我檢查了我所有的父表和它們的主鍵與我的新外鍵約束匹配。有人可以幫我解決這個問題。我的DDL和錯誤信息如下。在SQL Server表創建過程中出現外鍵約束錯誤

錯誤消息
消息1776,級別16,狀態0,第1行
引用表'I_IPV_LOB_PROG_PROV_MEAS_TRNS'中沒有與外鍵'RefI_IPV_LOB_PROG_PROV_MEAS_TRNS345'中的引用列表匹配的主鍵或候選鍵。
消息1750,級別16,狀態0,行1
無法創建約束。查看以前的錯誤。
你應該添加引起錯誤的引用表的DDL –
那麼這個錯誤真的已經說明了一切:你的外鍵'...._ TRNS345'使用了一列列** **匹配目標表上的任何主鍵或唯一約束。最有可能的是,你的列清單只是一個或某個東西。附註:由** 8列*(!!!!!)組成的PK確實是一個糟糕的主意,需要付出巨大的痛苦。你不能使用一個**單一的,代理**列作爲你的PK? –
