诠释到数字转换误差在SQL Server

Question

我有转换数据的问题。我在VBA做了一个选择查询，我如何从varchar值列转换为nvarchar。

我得到这个错误：

Arithmetic overflow error converting numeric to data type numeric

这是我的代码：

Dim strSQL As String 
Dim rst As New ADODB.Recordset 

strSQL = " INSERT INTO dbo.Soferi_test (test1)" & _ 
     " SELECT MySQL.dbo.sofieri.certificat_cipti " & _ 
     " FROM MySQL.dbo.sofieri " & _ 
     " WHERE IDNO = " & Forms!Forma_redactare_soferi!IDNO.Value 

Call AttServ(strSQL, rst) 

Answer 1

你的int值过大的数值精度和规模定义

在这里，我猜错误来自WHERE子句。不是INSERT

DECLARE @foo int = 99999; 
DECLARE @n1 numeric(9,1), @n2 numeric (3,2); 

-- 9,1 is 9 total digits, 1 decimal place 
-- 3,2 is 2 total digits, 2 decimal places 

-- 99999 requires at least 5 total digits 

PRINT 'Wide enough' 
SET @n1 = @foo; 


PRINT 'Error' 
SET @n2 = @foo; 

评论后，同样仍然适用

DECLARE @foo numeric(5,0) = 99999; 
DECLARE @n1 numeric(9,1), @n2 numeric (3,2); 

PRINT 'Wide enough' 
SET @n1 = @foo; 


PRINT 'Error' 
SET @n2 = @foo;
