sql - 在存储过程中将数据类型 varchar 转换为 bigint 时出错

Question

我试图用 usp_TimesheetsAuditsLoadAllbyId 42747, NULL 调用这个过程命令。

但我总是收到错误

Msg 8114, Level 16, State 5, Procedure usp_TimesheetsAuditsLoadAllById, Line 9
Error converting data type varchar to bigint.

ID的 TimesheetsAudits表是 bigint类型。我尝试了几种类型的转换和强制转换，但我现在真的被卡住了。

希望有人能帮忙。谢谢

ALTER PROCEDURE [dbo].[usp_TimesheetsAuditsLoadAllById]
(
    @Id INT,
    @StartDate DATETIME
)
AS
BEGIN
   SET NOCOUNT ON

   SELECT TOP 51 * 
   FROM 
      (SELECT TOP 51 
          ID,
          Type, 
          ReferrerId,
          CAST(Description AS VARCHAR(MAX)) AS Description,
          OnBehalfOf,
          Creator,
          DateCreated 
       FROM 
          TimesheetsAudits 
       WHERE 
          (ReferrerID = @Id) AND
          (@StartDate IS NULL OR DateCreated < @StartDate)
       ORDER BY
          DateCreated DESC

       UNION

       SELECT TOP 51 
          tia.ID,
          tia.Type, 
          tia.ReferrerId,
          '[Day: ' + CAST(DayNr AS VARCHAR(5)) + '] ' + CAST(tia.Description AS VARCHAR(MAX)) AS Description,
          tia.OnBehalfOf,
          tia.Creator,
          tia.DateCreated 
       FROM 
          TimesheetItemsAudits tia
       INNER JOIN 
          TimesheetItems ti ON tia.ReferrerId = ti.ID
       WHERE 
          (ti.TimesheetID = @Id) AND
          (@StartDate IS NULL OR tia.DateCreated < @StartDate)
       ORDER BY 
          tia.DateCreated DESC) t
   ORDER BY 
       t.DateCreated DESC
END

来自评论的表的表定义:

CREATE TABLE [dbo].[TimesheetsAudits]( 
  [ID] [bigint] IDENTITY(1,1) NOT NULL, 
  [Type] [tinyint] NOT NULL, 
  [ReferrerId] [varchar](15) NOT NULL, 
  [Description] [text] NULL, 
  [OnBehalfOf] [varchar](10) NULL, 
  [Creator] [varchar](10) NOT NULL, 
  [DateCreated] [datetime] NOT NULL
)



CREATE TABLE [dbo].[TimesheetItemsAudits]( 
  [ID] [bigint] IDENTITY(1,1) NOT NULL, 
  [Type] [tinyint] NOT NULL, 
  [ReferrerId] [varchar](15) NOT NULL, 
  [Description] [text] NULL, 
  [OnBehalfOf] [varchar](10) NULL, 
  [Creator] [varchar](10) NOT NULL, 
  [DateCreated] [datetime] NOT NULL
)

Answer 1

您执行 [dbo].[TimesheetsAudits] 和 TimesheetItems ti ON tia.ReferrerId = ti.ID 的 INNER JOIN

tia.[ReferrerId] 是 varchar，ti.[ID] 是 [bigint]。

我希望 tia.[ReferrerId] 中的值不能转换为 bigint。

请尝试以下操作:

SELECT [ReferrerId] FROM TimesheetItemsAudits WHERE ISNUMERIC(ReferrerId) = 0

这可能会帮助您找到“违规行”。
