示例XML：

  <TransactionSalary SL="7" Basic="9860.00" Grad_pay="4100.00" DA="6282.00" HRA="2094.00" MA="300.00" Ptax="150.00" pf="2000.00" Itax="0.00" LIC="0.00" Month_Of="20-Dec-2012" /> 
  <TransactionSalary SL="9" Basic="11850.00" Grad_pay="4800.00" DA="7493.00" HRA="2498.00" MA="300.00" Ptax="150.00" pf="2000.00" Itax="0.00" LIC="200.00" Month_Of="20-Dec-2012" />

错误：

Msg 8115，Level 16，State 8，Procedure Update_MCR，Line 42
算术溢出错误将十进制转换为数据类型数字。

我无法找出此错误发生的原因以及值。在插入的情况下，我采取在本网站提到的另一种方式。但再一次面对同样的问题。

我会：

将@xmlString的数据类型更改为XML - 它毕竟是XML - 对吧？
摆脱光标！你不需要它 - 它只是一个性能杀手 - 放弃它
摆脱“旧式”OPENXML的东西 - 使用SQL Server的原生XQuery支持！更容易使用

所以我的程序就像：

ALTER PROCEDURE [dbo].[Update_MCR]
     @xmlString  XML,
     @Message nvarchar(500) output
AS
BEGIN
    SET NOCOUNT ON;

    BEGIN TRY
        BEGIN TRANSACTION 

        ;WITH trsal AS 
        (
            SELECT
                SL = TrSal.value('@SL', 'int'),
                [Basic] = TrSal.value('@Basic', 'decimal(16,2)'),
                [Grad_Pay] = TrSal.value('@Grad_pay', 'decimal(16,2)'),
                [DA] = TrSal.value('@DA', 'decimal(16,2)'),
                [HRA] = TrSal.value('@HRA', 'decimal(16,2)'),
                [MA] = TrSal.value('@MA', 'decimal(16,2)'),
                [Ptax] = TrSal.value('@Ptax', 'decimal(16,2)'),
                [Itax] = TrSal.value('@Itax', 'decimal(16,2)'),
                [pf] = TrSal.value('@pf', 'decimal(16,2)'),
                [LIC] = TrSal.value('@LIC', 'decimal(16,2)'),
                [Month_Of] = TrSal.value('@Month_Of', 'datetime')
             FROM 
                @XmlString.nodes('/Salary/TransactionSalary') AS XTbl(TrSal)    
        )
        UPDATE [Monthly_Salary_Statement]  
        SET 
        [Basic] = trsal.Basic, 
        [Grad_pay] = trsal.Grad_pay, 
        [DA] = trsal.DA, 
        [HRA] = trsal.HRA, 
        [MA] = trsal.MA, 
        [Ptax] = trsal.Ptax, 
        [Itax] = trsal.Itax, 
        [pf] = trsal.pf, 
        [LIC] = trsal.LIC
        FROM
        trsal        
        WHERE
        [SL] = trsal.SL 
        AND MONTH([Month_Of]) = MONTH(trsal.Month_Of) 
        AND YEAR([Month_Of]) = YEAR(trsal.Month_Of)

      COMMIT TRANSACTION

      SET @Message = 'True'

    END TRY
    BEGIN CATCH
       ROLLBACK TRANSACTION

       SET @Message = 'sp_Update_Montly_Salary: ' + ERROR_MESSAGE()
