Question

I am using a capturing software, Abbyy FlexiCapture, after user done the verification (some sort of user key in data). It will export captured data into SQL Server 2008 R2

Once SQL Server identify there is an inserted data (new row), it will trigger code to update table Abbyy base on business rule.

The table has two columns called ProcessingDate and DateOfService

My business rule requirement is

1. If Processing Date is later than Date Of Service 7 month, it will update Table Abbyy
   • column CouponStatus with “Reject“,
   • column RejectCode with “A5“.
2. If Processing Date is earlier than Date Of ServiceDate 7 month, it will update Table Abbyy
   • column CouponStatus with “Approve”,
   • column RejectCode with “null”.

I am facing an error because some inserted data with Processing Date more than Service Date 7 month, column CouponStatus become “Approve“.

I am not sure is my trigger code problem or date format problem.
when user do validation, the date format is dd/mm/yy,

In SQL Server 2008 R2, my ProcessingDate and DateOfService column’s datatype is date with format yyyy-mm-dd

Here are my trigger code, pls focus start on line 86

USE [master]
GO
/****** Object:  Trigger [dbo].[BusinessRule]    Script Date: 10/03/2012 11:28:05 ******/
SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

Appreciate anyone can give me some guideline to solve this problem. Thank you.

Answer 1

Do some kind of date formatting before comparison to convert both values to the same format

Example :

WHERE CONVERT(VARCHAR,ProcessingDate,102) = CONVERT(VARCHAR,@ProDate,102)

OR

WHERE CONVERT(DATE,ProcessingDate,102) = CONVERT(DATE,@ProDate,102)
