Hi,
I have a development db and prod db. We have made some changes to dev and implement them in prod in another month. Before doing that we need to compare the current DEV and PROD for data accuracy.
How do I do that since I need to join 2 different tables in each database server? I wrote the script but the data is not correct. Also there is a table which has same customer details with diff record types, I need to compare the latest record type for each customer. How do I go about and do it?
The following script gives me wrong data:
SELECT PROD.ID as prod_id,PROD.xxx_NUMBER as prod_flight,PROD.xxxDATE as prod_dep,PROD.CENTRE as prod_cent,PROD.AUTOCOMMENTS as prod_autocomments,TEST.ID,TEST.xxx_NUMBER,
TEST.xxx_DATE,TEST.CENTRE, TEST.AutoComments,TEST.RECORD_TYPE,PROD.RECORD_TYPE as prod_type,test.Created_Timestamp,prod.Created_Timestamp as prod_createdtime
into test_table FROM
(SELECT top 1 A.Record_Type,A.Created_Timestamp,A.ParentcustId,B.xxx_Number,B.xxx_Date,B.Centre,B.ID,B.AutoComments
FROM recorsChanges A JOIN customer B ON A.ParentcustId=B.ID where LTRIM(RTRIM(SUBSTRING(B.AUTOCOMMENTS,15,11))) ='15/04/2014'
and a.RECORD_TYPE IN(1,2,3,4,5,6,7)
AND convert(date,a.Created_Timestamp) = '04/15/2014' order by a.Created_Timestamp desc ) TEST
JOIN(SELECT D.Record_Type,D.Created_Timestamp,D.parentcustId,C.xxx_Number,C.xxx_Date,C.Centre,C.ID,C.AUTOCOMMENTS
FROM prod_server.db_name.DBO.cust C JOIN
prod_server.db_name.DBO.recorsChanges D ON D.ParentcustId=C.ID where LTRIM(RTRIM(SUBSTRING(c.AUTOCOMMENTS,15,11))) ='15/04/2014'
and d.RECORD_TYPE IN(1,2,3,4,5,6,7)
AND convert(date,d.Created_Timestamp) = '04/15/2014' ) PROD
ON TEST.xxx_Number=PROD.xxx_Number AND TEST.Centre=PROD.Centre AND TEST.xxx_Date =PROD.xxx_Date
This is giving me wrong data mapping bet 2 servers. I need to compare if the record_type in test is same as in prod for the respective created_time. It is mapping the record_type of a particular created_time with record_type created in test in a different created_time. Any easy way to do this comparison
