Dear All,

Need some Suggestion.

I have two tables one is Master and other one is slave.

MY master table has some set of Data and slave tables contains data set from many slaves.

Here is the sample data

Master
No. Type Version Date
1 Sales V1.0 01/10/2012
2 Consumption V1.10 29/10/2012
3 Daily Needs V1.01 13/08/2011
4 Overall V2.01 01/09/2012

Slave
Code No. Type Version Date
S001 1 Sales V1.0 01/10/2012
S001 2 Consumption V1.10 29/10/2012
S001 3 Daily Needs V1.01 13/08/2011
S001 4 Overall V2.01 01/09/2012
S001 5 Electricity V5.01 18/10/2012
S002 1 Sales V1.0 01/10/2012
S002 2 Consumption V1.10 15/10/2012
S002 3 Daily Needs V1.1000 13/08/2011
S003 1 Sales V1.0 01/10/2012
S003 2 Consumption V1.10 29/10/2012
S003 4 Overall V2.01 01/09/2012
S003 3 Daily Needs V1.01 13/08/2011
S003 4 Overall V2.01 01/09/2012
S003 5 Electricity V5.01 18/10/2012

Now, i have to compare Master with slave and then Slave with Master.

Here are conditions.

1. IF my master and slave matches then report says MATCH
2. IF my master and slave doesnt matches then report says MISMATCH
3. IF my Master contains more data than slave then report says Missing at Slave
4. IF my slave contains more data than Master then report says Missing data at Master.

i know how to get the data, but i want quickest way as my slave table contains millions of record, i want my process to be very quick.

Summarization of test cases.

Final Report
Master Slave Status
Code No. Type Version Date Version Date
S001 1 ALL Match
S002 2 Daily Needs V1.01 13/08/2011 V1.10013 /08/2011 Mismatch
S002 3 Daily Needs V1.01 13/08/2011 V1.1000 13/08/2011 Mismatch
S002 4 Overall V2.01 01/09/2012 V5.01 18/10/2012 Missing in Slave
S003 5 Electricity V5.01 18/10/2012 Missing in Master

PLease let me know if anybody have quick way to do it.

thanks

Regards.
Deepika

IF you show your code for the solution and the execution plan then you may get some suggestions on optimization.

This sounds like a relational division problem,ie some rows, equal rows, more rows...

Joe Celko has done a good write up on the subject, http://www.simple-talk.com/sql/t-sql-programming/divided-we-stand-the-sql-of-relational-division/

Hello

You are likely to get a much faster response if you provide DDL for your sample data. Here's your 'master' table, can you do the same with the 'slave' table? Make sure it runs without errors and that the data is correct before you post it. Thanks.

CREATE TABLE #Master ([No] INT, [Type] VARCHAR(20), [Version] VARCHAR(10), [Date] DATE)
SET DATEFORMAT DMY
INSERT INTO #Master ([No], [Type], [Version], [Date])
SELECT 1, 'Sales', 'V1.0', '01/10/2012' UNION ALL
SELECT 2, 'Consumption', 'V1.10', '29/10/2012' UNION ALL
SELECT 3, 'Daily Needs', 'V1.01', '13/08/2011' UNION ALL
SELECT 4, 'Overall', 'V2.01', '01/09/2012'

SELECT * FROM #Master
