＆＃39; 0＆＃39;附近的语法不正确。 （Microsoft SQL Server）

Question

当我执行下面的程序时，它会返回Incorrect syntax near '0'。我不知道为什么。

错误已在Msg 102, Level 15, State 1, Line 43中进行了本地化。你能告诉我出了什么问题吗？谢谢你提前。

CREATE PROCEDURE [dbo].[PV_SaveCategory]

Answer 1

我看到了2个问题。

1. 您在insert命令中定义了12个字段，只有11个值
2. update语句没有列名（第一个除外）

它应该是这样的：

UPDATE [DB].[dbo].[Category_' + CONVERT(NVARCHAR, @AccountID, 0) + '] 
SET  Level = CASE WHEN @ParentID IS NULL THEN 0 ELSE @Level END,
     field1 = 0,
     field2 = 1,
     field3 = 2,
     field4 = 3,
     field5 = 4,
     field6 = 'test2'
 Where @CategoryID = Id 
 AND   @ParentID = ParentCategoryID

Answer 2

在将值分配给其他缺少左侧列名称
