這是正在返回什麼： enter image description here

我已經努力並設置爲空OriginalEstimateHours但0返回。我怎樣才能讓這些單元變成空白？

什麼是Effort和OriginalEstimateHours的類型？我猜想某些數字，他們不允許是空的？您可能想要返回一個僞造號碼，例如-99以顯示它實際上是「false」 – Dave

您發佈的查詢與您顯示的結果集不匹配。「Category」，「IncidentNumber」等去了哪裏？ 'MondayHours'已經成爲'Monday' –

他們的類型是INT和BIGINT，這可能就是爲什麼會出現這種情況。但我仍然希望它是空的。 –

我懷疑STY.Effort和TSK.OriginalEstimateHours（SELECT子句中的行爲RowType 3）是數字。

從文檔UNION：

作爲UNION操作的一部分列的定義不必相同，但它們必須通過隱式轉換兼容。 當數據類型不同時，結果數據類型根據data type precedence的規則確定。

（我強調）

裹那些列在CONVERT(varchar(20),STY.Effort)以便選擇用於這些列類型是varchar而不是數字類型。

它們的類型INT和BIGINT，

如果你想要一個空字符串，而不是0或NULL，您將需要使用CAST或CONVERT功能列轉換爲VARCHAR類型。您不能在數字列中輸入空字符串。您可能還需要使用CASE語句將0字符串轉換爲空字符串。

當您分配空字符串時，取決於數據類型，它將轉換爲不同的值。 0表示整數，1900-01-01表示日期等。請參閱此處瞭解更多信息 http://beyondrelational.com/modules/2/blogs/70/posts/10841/empty-string-and-default-values.aspx
