可能重複：
recursive function.. won’t work again SQL

我創建包含0和99之間的數字的表格; 對於這兩個數字的查詢工作， 和它的工作對這些數字太之間的數字： 100，200，1000，2000，1100，2100年，100萬一般來說，適用於數量> 100，並且不包含我已經創建的表格中的一個數字.. 和所有其他數字我得到'空'。 我認爲問題出在變量@Units中，但我不能再專注於此。

問題可能是您正在追加到result而未初始化它。空字符串不是空字符串（在大多數數據庫中）。

嘗試改變聲明：

DECLARE @result as nvarchar(1024) = '' 

或者，如果您使用的是舊版本的SQL Server：

DECLARE @result as nvarchar(1024); 
SET @result = = ''
