我的存储过程：

ALTER PROCEDURE [dbo].[Spaddvoucherreachcols] @xml   XML,
                                              @error VARCHAR(1000) output
AS
  BEGIN
      BEGIN TRY
          INSERT INTO VoucherReachCols
                      (ColName,
                       Title,
                       DataSource,
                       ControlID,
                       MaxLength,
                       Width,
                       Height,
                       IsMandatory,

                 N.value('(ColName)[1]', 'Varchar(MAX)'),
                 N.value('(DataSource)[1]', 'Varchar(MAX)'),
                 N.value('(ControlID)[1]', 'NVarchar(MAX)'),
                 N.value('(MaxLength)[1]', 'NVarchar(MAX)'),
                 N.value('(Width)[1]', 'NVarchar(MAX)'),
                 N.value('(Height)[1]', 'NVarchar(MAX)'),
                 N.value('(IsMandatory)[1]', 'Varchar(MAX)'),
                 N.value('(CreatedBy)[1]', 'int'),
                 Getdate(),
                 Getdate(),
                 1,
                 N.value('(UpdatedBy)[1]', 'int'),
                 N.value('(IPAddress)[1]', 'Varchar(20)')
          FROM   @XML.nodes('/Table/VoucherReachCols') AS T(N);
      END TRY

      BEGIN CATCH
          SET @Error = Error_number() + ' ' + Error_message();
      END CATCH
  END

Answer 1

错误非常自我解释。尝试替换

N.value('(ControlID)[1]', 'NVarchar(MAX)'),
N.value('(MaxLength)[1]', 'NVarchar(MAX)'),

与

N.value('(ControlID)[1]', 'int'),
N.value('(MaxLength)[1]', 'int'),

编辑：检查源表：IPAddress varchar（1） - 在实际插入中我注意到varchar（20）的IPAddress。您应该更改表并增加此列宽。

如何解决此错误：转换nvarchar值时转换失败＆＃39; String或二进制数据将被截断。＆＃39;到数据类型int
