Sql For Comparing Two Tables
Aug 2, 2004Hi everyone,
I have 2 seperate databases and I need to check for rows that are different from each other in a table.
I used access to link the tables in a database and am using queries to check the tables. However, I am having trouble formulating the SQL. What I want to do is not just check for the ID field to see if it exists, but to make sure the whole row exists. How can I form an SQL statement for this?
I tried something like:
Select * from table1 where Column1 NOT IN (Select Column1 from Table2) AND Column2 NOT IN (Select Column2 from Table2). However, I do not think this is correct. I want to make sure that the rows are compared, not individual values.
Any help would be appreciated.
Thanks,
Pankaj

Comparing Two Tables.
Aug 24, 2007I'm having a bit of a brain melt.
I've got two identical tables (except for the names) and I need to run a query that outputs the rows that aren't in the primary table.
To clarify table one has 38,450 records and table two has 30,703. I need to output the records that are in table one but not table two.
Everything I've tried keeps returning the records that are in it. They have a ID as primary key and a userid field which is what I want to be able to list.
Any ideas?
Thanks.
Comparing Tables Again
Dec 28, 2007I need to compare two tables and update the records that have changed.
The following code works great for that:
SELECT MIN(TableName) as TableName, ID, COL1, COL2, COL3 ...
FROM
SELECT 'Table A' as TableName, A.ID, A.COL1, A.COL2, A.COL3, ...
FROM A
UNION ALL
SELECT 'Table B' as TableName, B.ID, B.COL1, B.COl2, B.COL3, ...
FROM B
) tmp
GROUP BY ID, COL1, COL2, COL3 ...
HAVING COUNT(*) = 1
ORDER BY ID
However, I also need to compare the two tables and see if there are any new records or deleted records. What would those queries look like? Can they all somehow be combined into one query?

Comparing Fields In Tables
Aug 4, 2005I am working with the article that MAK wrote on SecurityLogs http://www.databasejournal.com/features/mssql/article.php/3515886
I have completed this, but I have made some changes to the database (for normalization to 3NF purposes). I now have problems with a query.
I am trying to "Insert a new record in a table if it does not already exist in the table". To try to clarify I perform the following query:
INSERT INTO Tmp_Event
SELECT DISTINCT EventID, EventType, EventTypeName from Tmp
Which gives me the Tmp_Event table consisting of EventID's etc. (no duplicates). What I then want to do, is compare the 'Tmp_event' table and an already existing 'Event' table. These two tables are in fact identical. I would like to insert any records from 'Tmp_Event' into 'Event' if they do not already exist in 'Event'.
This query gives me all records that do not exist in 'Event'
SELECT EventID, EventType, EventTYpeName from Tmp_Event
WHERE EventID NOT IN (SELECT EventID from Event)
How can I change this query into performing an INSERT INTO Event as well?
Hope this makes sense :)

Comparing Tables In SQL Server 2k
Dec 29, 2004I have two tables that share (supposedly) 2 fields (PartID and RaceID) and those two tables should be identical as far as those two fields are concerned. That is, there should be the same number of rows in both tables and if listed in the same sort order in reference to these two fields, they should be identical. The problem is, they are not. There are in excess of 3000 records in each field and I need to write a query that will allow me to compare them row-by-row.
I am using sql server 2000 and I am (kind of)familiar with the SQL Query Analyzer. What I really need to know is how to write the select statement that will allow me to compare the two tables line-by-line to find the discrepancies or, better yet, simply show the discrepancies so I can focus on them.
Thanks!

Comparing Two Tables In Two Different Databases

Note that both databases are mirrors of each other but contain slightly different data and are on different servers.
Comparing Large Tables
Oct 19, 2007
I've successfully created SSIS packages where I compare two tables in different databases on different servers. However, this is good enough to compare hundreds of thousands of records quickly. The process becomes a huge performance problem when trying to compare table differences when I'm looking at tables that each contain tens of millions of records.
One database is on a SQL 2005 box and the other DB is SQL 7.0 so the lookup component fails for this type of SQL Server. I've been implementing merge joins and conditional components to do my standard table comparisons.
Is there another way to implement this process or maybe partition it somehow to take pieces of the table at a time and compare them? I'm open to ideas.
Comparing Two Tables And Updating As Needed.
Jan 5, 2004I have two tables in seperate dbs that I need to match up users and update the passwords in the second db table. I know how to match up the data and I'm sure I can do this using a cursor but I was wondering if there is a way I can do this with an update statement. Any suggestions(including telling me I'm stuck using a cursor) would be great.
Thanks ahead of time
EDIT: Nevermind, figured it out :D Thanks anyway.

Comparing Data In Tables/views.
May 13, 2008I am looking for an efficient mechanism to compare data between 2 tables/views.
Rationale:
I use a proprietary tool to data transfer between 2 databases. The tool itself uses Microsoft SSIS (integration service) to transfer data. I want to make sure that the data is transfered properly. Both the source and target database are not live database. The source and target database are in seperate servers.
Comparing Data And Integrity Between Two Tables
Jun 4, 2008Hi everyone,
I have recently converted my DTS packages to SSIS and deployed them to the new server. I have the 2000 and 2005 server running concurrently, all that is left for me to do is compare the the tables generated by the DTS and SSIS packages to see if they are the same.
How do I go about comparing the tables, which are from two different servers using SQL server 2005?

Comparing Two Tables Or Views Easily
Jan 15, 2003Based on the discussion at:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=23038
and BSmith's idea (no relation), I came up with this silly stored proc to compare any two tables or views. Supply the table names and the columns you wish to compare and have fun!
The key to the GROUP BY approach is that it handles NULLS quite well which JOINS have trouble with.
CREATE PROCEDURE CompareTables(@table1 varchar(100),
@table2 Varchar(100), @T1ColumnList varchar(1000),
@T2ColumnList varchar(1000) = '')
AS
-- Table1, Table2 are the tables or views to compare.
-- T1ColumnList is the list of columns to compare, from table1.
-- Just list them comma-separated, like in a GROUP BY clause.
-- If T2ColumnList is not specified, it is assumed to be the same
-- as T1ColumnList. Otherwise, list the columns of Table2 in
-- the same order as the columns in table1 that you wish to compare.
--
-- The result is all records from either table that do NOT match
-- the other table, along with which table the record is from.
declare @SQL varchar(8000);
IF @t2ColumnList = '' SET @T2ColumnList = @T1ColumnList
set @SQL = 'SELECT ''' + @table1 + ''' AS TableName, ' + @t1ColumnList +
' FROM ' + @Table1 + ' UNION ALL SELECT ''' + @table2 + ''' As TableName, ' +
@t2ColumnList + ' FROM ' + @Table2
set @SQL = 'SELECT Max(TableName) as TableName, ' + @t1ColumnList +
' FROM (' + @SQL + ') A GROUP BY ' + @t1ColumnList +
' HAVING COUNT(*) = 1'
exec ( @SQL)

Update/Delete/Add Comparing 2 Tables
Mar 12, 2008Hi,
Im pretty new to SQL Server, but was able to create a dsn conenction to our dbf database, and then use sql script to import the table into sql server using this script below:
use cameodata;
/* Drop stock Table */
IF EXISTS (
SELECT 1
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'stock'
AND TABLE_SCHEMA = 'dbo'
AND TABLE_TYPE = 'BASE TABLE'
)
BEGIN
DROP TABLE stock
END
/* Import stock Table */
select * into stock
from openrowset ('msdasql','dsn=stock',
'select * from stock')
So basically everytime i run this script, it deletes the table in sql server and then imports the latest copy.
The problem is that this table is huge and it takes a while. What Id rather have is a script that i could run that would compare the dsn connected table with the table currently on sql server and if there are any updates then update sql server, if there are items on the sql server that are not the the latest copy, then delete that record on the sql server table and also if there are new items on the lastest copy then add the new record to the sql server table.
Is this possible?
thanks,
Anthony.
Comparing Tables In Different Servers (EXCEPT/INTERSECT)
Nov 14, 2007Hi people!!!
First I'll introduce my situation.
I have the folowing tables:
1.- Table "Codes", DataBase "COD", server 1001
2.- Table "Codes", DataBase "COD", server 1002
Both servers run SQL Server 2000 Edition.
What i need to perform is a check that compares the data stored in both tables in order to know if there is any difference between them. Of course, the structure of both tables are the same.
I use the SP sp_addlinkedserver to link the servers, but the problem is that EXCEPT and INTERSECT didn't work.
Anyone can help me?
Thanks,
Bob
P.S.: Please!!!!!!!!!

SQL Server 2008 :: Comparing Tables For Like Values?
Jul 17, 2015I have a table of raw data with supplier names, and i need to join it to our supplier database and pull the supplier numbers.
The issue is that the raw data does not match our database entries for these suppliers; sometimes there are extra periods, commas, or abbreviations (i.e. FedEx, FederalExpress, FedEx, inc.) etc. I'm trying to create a query that will search for entries that are similar.
I tried setting a variable to be equal to the raw data field, and then using a LIKE '%@Variable%' to try and return anything that would contain it, but it didnt return any rows.
Problem With Comparing 2 Text Columns In 2 Tables

When i compared the 2columns with the LIKE operator i found something strange.create table test1( var1 text )create table test2( var1 text )insert into test1 values ( '-- [ CustomerType = 1 ]' )insert into test2 values ( '-- [ CustomerType = 1 ]' )select * from test1, test2where test1.var1 like test2.var1The last query surprisingly did not return any results. However when itook of the '[' in the text data and had something like thisinsert into test1 values ( '-- CustomerType = 1 ]' )insert into test2 values ( '-- CustomerType = 1 ]' )the query returned expected results, showing one row.any helpful would be great.Regards,Arun Prakash.

Aug 9, 2015I have a table containing records of criminal convictions. There are over 1M records and the only change is additions to the table on a monthly basis. The two columns I need to deal with are convicted.NAME and convicted.DOB
I have a second table that has 2 columns. One is the name of the defendant and the other is the birth date. This would be monitor.NAME and monitor.DOB
There are no primary keys or any other way to join the tables for this search I want to do.
I would like to be able to put a name in the "monitor" table and run a query to see if there is a match in the convicted table.
The problem I am having is middle initials or names. If I want to monitor.name = 'SMITH JOHN' it will return the results fine. The problem I am having is if the conviction is in the database as 'SMITH JOHN T', or 'SMITH JOHN THOMAS'.
How can I use the monitor table with a 'LASTNAME FIRSTNAME' and return results if the convicted table has a middle initial. I tried with a JOIN:
select distinct convicted.*
from convicted
join monitor
on monitor.name like convicted.defendant
and monitor.birthdate = convicted.dob

View 1 Replies View RelatedComparing Similar Tables - Removing Duplicate Or Repeated Data
Sep 30, 2007It seems that there should be a solution for my situation, but for the life of me I can't seem to figure it out.
I need to compare two "like" tables, containing similar data. Tbl 1 is "BOOKED" (which is a snapshot of inventory) and tbl 2 is "CURRENT" (the live - working inventory table). If I write my query as follows the the subsequent result is "duplicate" data.
Code Block
SELECT booked.item, booked.bin, booked.quantity, current.bin, current.quantity
FROM BOOKED
LEFT JOIN
CURRENT
ON booked.item = current.item
No matter what type of join I use, there is duplicate data displayed for each table. For example, if there are more bins in the BOOKED table that contain a certain product then the CURRENT table will repeat data and vica versa.
As follows:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345

What I would like to do is display Bin and Quantity only once and the repeating values as NULL or [BLANK]. Or, to display all of the bins from both tables and only the quantities from each table in relation to the bin found in that table, returning a "0" if no quantity exists.
This is what I'm after:

Is this possible? If so, how?
I also might add that it is ok for each table to contain multiple entries for any given item. This is basically being requested as an inventory variance report - inventory before physical count and immediatly after physical count - and will only be run once a year.
-----------------------------------------------
Just thinking out loud here:
What if I created three subqueries, the first containing only BOOKED information, the second containing only CURRENT information and the third being a UNION of both tables? Something like this:
Code Block
SELECT q3.bin, q1.item, ISNULL(q1.quantity, 0) as QTY_BEFORE, ISNULL(q2.quantity, 0) as QTY_AFTER
FROM
(select item, bin, quantity
from BOOKED)q1
Left Join
(select item, bin, quantity
from CURRENT)q2
on q1.item = q2.item
Left Join
(select bin, item
from BOOKED
UNION
CURRENT)q3
on q1.item = q3.item
Order By q1.item
I don't know if I wrote the UNION statement correctly, but I will have to try this when I get back to work...
Any suggestions?
SQL Server 2008 :: Comparing Integer Values Across Tables And Database Servers?
Mar 6, 2015how best to approach a problem involving two tables across two different servers.
Table 1: Contains IP Address along with assessment findings. Lets say the fields are IPADDRESSSTR, FINDING
Table 2: Contains Subnet information stored in integer format. The fields are SITE_ID, LOW, and HIGH
What I'd like to do is load the IP range information into memory and then return the findings from table 1 where the IPADDRESSSTR is between the LOW and HIGH integer value.
1) Is there a way to load all of the ranges from table 2 into an array and then compare all the IP addresses (IPADDRESSSTR) from table 1?
2) How do I convert IPADDRESSSTR (a string) to an integer to perform the comparison.
&"Select&" Comparing Two Tables
Nov 3, 2005I am trying to select a dataset from one table that compares to certain criteria in another table. (i.e. select * from PR_Reservations where PR_Reservations.resource_id = Add_Record.resource_id). I get an error message stating the column prefix "Add_Record does not match with a table name or alias name used in the query." The Add_Record table is a temporary table and will only have one row of data at any given time.
However, the following query works so I know it is recognizing the table: Select * from Add_Record where resource_id=4.
Should I make "Declare" statements for all variables in the Add_Record table that I need to make a comparison on?
What am I doing wrong?
