案例中的SQL Server 2008更新

Question

我正在嘗試創建一個存儲過程，用於將呼叫分配給呼叫者。我們有幾個由變量@team_id標識的調用者小組。我想要做的是檢查並確定客戶（@code）是否有人分配給他們。如果他們這樣做，則返回該人的ID。如果沒有，請運行THEN語句來確定應將其分配給誰，將記錄更新爲該調用方，然後返回該調用方的標識。這是我的，但它不會讓我運行選擇內的更新。如果可以的話，我想避免每次更新表（將更新子句添加到存儲過程的末尾）。

Answer 1

爲什麼不先更新然後在第一個IF語句裏面選擇一個select。 您可以在更新語句中應用相同的條件邏輯。

編輯：這裏是code.Not雖然測試....
