叫这个程序

我正在尝试使用usp_TimesheetsAuditsLoadAllbyId 42747 NULL命令调用此过程。

但是我总是会出错

消息8114，级别16，状态5，过程usp_TimesheetsAuditsLoadAllById，第9行将数据类型varchar转换为bigint时出错。

TimesheetsAudits表的ID是bigint类型。 我尝试了几种类型的转换和强制转换，但现在我真的很困难。

具有不同Parameters顺序的Insert Query和Value查询，这导致发出Insert语句。 对您的Insert查询尝试此操作，

ALTER PROCEDURE [dbo].[spInsertLoanMaster]
   @TAc_no bigint
   ,@TAcc_no bigint
  ,@TAc_name nvarchar(50)
  ,@TV_no bigint
  ,@TJlg_no bigint
  ,@TPost_no bigint
  ,@TPhone_no1 bigint
  ,@TAct_no bigint
  ,@TLoan_amt bigint
  ,@TLoan_date date
  ,@TInt_rate bigint
  ,@TPay_mode nvarchar(max)
  ,@TPrin_inst nvarchar(max)
  ,@TGuar_name1 nvarchar(50)
  ,@TGuar_name2 nvarchar(50)
  ,@TChq_no bigint

  ,@TGurAdd2 nvarchar(100)
  ,@TGurPhone1 nvarchar(100)

您存储过程的插入中的参数与传递的变量不匹配。
