當我在.EDMX文件中右鍵單擊,然後單擊Generate Database From Model時,由於表名稱,產生的腳本顯然是錯誤的。它生成的是以下腳本。請注意0​​部分中的表名與CREATE TABLE部分中的表名。EF4生成無效腳本

這是爲什麼不一致?

這顯然不是一個可重複使用的腳本。我創建的是一個名爲「Address」的實體和一個名爲「Company」的實體等(都是單數形式)。 EntitySet名稱被複數化。 「多重新對象」布爾值也不會改變這個。那麼交易是什麼?

對於它的價值,我最初生成EDMX的方法是將它指向一個具有非複數名稱表的數據庫,現在我已經做了一些更改,我想以其他方式返回。我希望可以選擇來回切換,因爲db-first和model-first模型在所有情況下都不是理想的,並且我有控制權確保不會有多人同時出現合併問題方式在同一時間。

我一直無法找到這個問題的答案。另外,我在重新創建這個問題時遇到了問題,我不會從DB優先到模型優先的情況。因此,我只是假設來回發生了問題,並且是通過EF來解決問題的一個不好的情況。
