Comparing 2 Records SQL Query
May 9, 2008Hey Guys, I have a contacts table that contains ID, First Name, Last Name, and Phone Number, Date Entered, Changed. Every time, the data is modified and saved, it will insert a new record in the table. So, Ill create a new record for a contact named Ryan, and then come back a day later and update the last name and phone number. So theSQL table would look like...1 Ryan Scott 818-550-0000 05/08/2008 Null2 Ryan Peters 000-000-0000 05/09/2008 Null How do I write a sql query that will run an update after the insert of the second record to fill in the Changed field with the data that changed?So I want to have record 2, end up looking like this... 2 Ryan Peters 000-000-0000 05/09/2008 LastName,PhoneNumberAny ideas?

Comparing Millions Of Records From File A And B
Sep 11, 2006I'm trying to compare about 28 million records (270 length) from table A and B using the Lookup task as described in this forum. The process works fine with about two million records or so on my desktop ( p.4 3.39GHz, 1.5 GB Ram), but hangs with the amount of data I'm trying to process. I tried using full and partial caching, but to no avail. I'm thinking this is a hardware resource problem. So, does anyone has any recommendation on the hardware needed for this kind of operation and/or suggestion? Thanks in advance...

Comparing Data In Two Tables To Find Missing Records
Jul 20, 2005I have two tables of book information. One that has descriptions of thebook in it, and the isbn, and the other that has the book title,inventory data, prices, the isbn.Because of some techncal constraints I won't get into now, I can'tcombine them both into one table. No problem. Things are going fine aslong as there is a description in the one table to corrispond to theisbn and other data in the other table.However, about half of the products are not yet entered into thedescrition table. I'd like to run a sql query that pulls up all theisbns that don't exist in the other. In other words, I'd like to get aquery that tells me exactly which isbns do not yet have descrition datain them. I know there is some sql that says to search from one filewhere the number does not exist in the other, but it slips my mind. Cansomeone help me on this please?Thank you!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Transact SQL :: Comparing Previous Records Based On Each ID Column
Aug 21, 2015I have a scenario to compare previous records based on each ID columns. For each ID, there would be few records, I have a column called "compare", We have to compare all Compare 1 records with Compare 0 Records. If Dt is lesser or equal to comparing DT, then show 0. Else 1
We always only one Compare 0 records in my table, so all compare 1 columns will compare with only one row per ID
My tables look like
Declare @tab1 table (ID Varchar(3), Dt Date, Compare Int)
Insert Into @tab1 values ('101','2015-07-01',0)
Insert Into @tab1 values ('101','2015-07-02',1)

Insert Into @tab1 values ('102','2015-07-02',1)
Insert Into @tab1 values ('102','2015-07-01',1)
select * from @tab1
1.) In the above scenario for ID = '101', we have 5 records, first record has Compare value 0, which mean all other 4 records need to compare with this record only

3.) If Compare 1 record's Dt is greater than Compare 0's DT, then show 1 in next column

SQL Server 2008 :: Comparing / Merging Records In Single Table?
Jun 2, 2015I'm trying to avoid a large amount of manual data manipulation.
Here's the background: Legacy system that has (well let's call apples apples) pretty much no method of enforcing data integrity, which has caused a fairly decent amount of garbage data to be inserted in some tables. Pulling one of the [Individuals] table from within this Legacy system and inserting it into a production system, into the Table schema currently in place to track [Individuals] in this Production system.
Problem: Inserting the information is easy, how to deduplicate the records that exist within the staging table that the legacy [Individuals] table has been dumped into in production, prior to insertion. (Wanting to do this programmatically with SQL or SSIS preferably, so that I can alter it later to allow for updating existing/inserting new)
Staging Table Schema:
;
CREATE TABLE [dbo].[stage_Individuals](
[SysID] [int] NULL, --Unique, though it's not an index intended to identify the [Individuals]
[JJISID] [nvarchar](10) NULL,
[NameLast] [nvarchar](30) NULL,
[NameFirst] [nvarchar](30) NULL,
[NameMiddle] [nvarchar](30) NULL,
[code]....
Scenario: There are records that duplicate the JJISID, though this value is supposed to be unique for every individual. The SYSID is just a Clustered Index (I'm assuming) within the Legacy system and will be most likely dropped when inserted into the Production [Inviduals] table. There are records that are missing their JJISID, though this isn't supposed to happen either, but have valid information within SSN/DOB/Name/etc that can be merged into the correct record that has a JJISID assigned. There is really no data conformity, some records have NULLS for everything except JJISID, or some records will have all the [Individuals] information excluding the JJISID.
Currently I am running the following SQL just to get a list of the records that have a duplicate JJISID (I have other's that partition by Name/DOB/etc and will adapt whatever I come up with to be used for those as well):
;
select j.*
from (select ROW_NUMBER() OVER (PARTITION BY JJISID ORDER BY JJISID) as RowNum, stage_Individuals.*, COUNT(*) OVER (partition by jjisid) as cnt from stage_Individuals) as j
where cnt > 1 and j.JJISID is not nullNow, with SQL Server 2012 or later I could use LAG and LEAD w/ the RowNum value to do my data manipulation...but that won't work because we are on SQL Server 2008 in this environment.
[URL]
With, the following as a potential solution:
GSquared (3/16/2010)Here's a query that seems to do what you need. Try it, let me know if it works.
Performance on it will be a problem, but I can't fine tune that. You'll need to look at various method for getting this kind of data from the table and work out which variation will be best for your data. Without access to the actual table, I can't do that.
;
WITH CTE
AS (SELECT master_id,
MIN(ID) AS first_id,
MAX(Account_Expiry) AS latest_expiry
FROM #People
GROUP BY master_id)
SELECT P1.master_id,
[code].....
Unfortunately, I don't think that will accomplish what I'm looking for - I have some records that are duplicated 6 times, and I'm wanting to keep the values within these that aren't NULL.
Basically what I'm looking for, is to update any column with a NULL value to the corresponding Duplicate [Individuals] record value for that column.
**EDIT - Example, Record 1 has a JJISID with NULL NameFirst & NameLast BUT Record 2 has the same JJISID and values for NameFirst & NameLast. I'm wanting to propogate the NameFirst & NameLast from Record2 into Record1
Transact SQL :: Comparing 2 Records / Multiple Instances In The Same Table For A Specific Combination?
Jun 10, 2015I have a problem where I have 2 compare 2 records from the same table. This part looks easy but the problem is for a User there can be multiple records and I have 2 compare each record with its previous instance based on the timestamp. Not only I have to compare I have to perform some analysis. Below is the Table script and sample output.
Givens: All SQL Server 2008 or 2012 tools at your disposal.
Production database contains the following tables (simplified for example: constraints ignored, etc.) associated with a racing video game’s server.
-- A player of our game
-- Table greater than 10 million rows
CREATE
TABLE [dbo].[User]
(
[UserId]
[bigint] NOT
NULL
,[country]
[int] NULL
-- User’s home country
,[name]
[nvarchar](15)
NULL -- User’s displayable name (‘John’, ‘Bill’)
,[subscriptionTier]
[int] NULL
)
-- 0 == free, 1 == paid, for instance
Assume that rows get written into the event tables at a rate of 1,000 a minute,are never updated once written and currently are only read on a replica/reporting server.
Question Background: Write up a single query that would return the following: List of users and whose “TotalMoneyEarned” value ever grew (between logon events) at a rate of more than 1,000 per minute (we’d consider these suspicious and flag them for later investigation).
For instance, if the sample data were:
-- example of [Events.UserLogon] data -- not the query output we want
EventId UserId TotalMoneyEarned LogonDate
----------- -------------------- ---------------- -----------------------
1 1 1000 2010-10-16 00:19:56.460
2 1 1500 2010-10-16 00:20:56.460
3 1 3000 2010-10-16 00:21:56.460
4 1 10000 2010-10-16 00:29:56.460
Event 1 is okay because there’s nothing to compare it against
Event 2 is okay because the TotalMoneyEarned only grew 500 in a minute
Event 3 should be flagged, as the value grew 1500 in a minute
Event 4 is okay, as it grew 7,000 in 8 minutes (< 1000 per minute)
Query Output (your query should return data in a format like this):
User Flagged Logon Time Rate Since Last Logon (money/minute)
John 2010-10-16 00:21:56 1500
Dave 2010-10-16 00:30:50 3200
Bill 2010-10-16 00:35:23 1000
It is likely that you will need to create sample data for both the User and [Events.Logon] tables. We are looking for a single query that returns data like what is represented in Query Output.
Comparing Date Records In One Column To Know Missing Date Interval?
Jun 6, 2012I need to compare the contents of a column.
I have a table with 1 column. Below are the sample contents..
DateInterval
2012-06-01 00:30:00.000
2012-06-01 01:00:00.000
2012-06-01 01:30:00.000
2012-06-01 02:00:00.000
2012-06-01 02:30:00.000
[code]....
as you can see, the records have a 30minutes time interval. i need to create a query to know if there are missing records in the table. so basically the result should be this:
DateInterval
2012-06-01 18:00:00.000
2012-06-01 20:30:00.000
if it is not doable, we can get the nearest record of all missing records like this:
DateInterval
2012-06-01 17:30:00.000
2012-06-01 20:00:00.000
or this:
DateInterval
2012-06-01 18:30:00.000
2012-06-01 21:00:00.000
or this:
DateInterval
2012-06-01 17:30:00.000
2012-06-01 18:30:00.000
2012-06-01 20:00:00.000

Comparing Dates In SQL

For example, table1 has a field called LastUpdate and table 2 has a field called LastUpdate. I need to grab only the most recent date. I tried this using an inner join...but that didn't work because it only picks the lastupdate form one table only. talbe1 and table2 are tied by table2.table1id.

Comparing Dates
Jul 10, 2001How do i compare 2 dates without comparing their Time portions. I have a Datetime column in my table which for example has values :-
6/6/2001 7:23:42 PM
6/6/2001 8:01:08 PM and so on....
I have a Stored Procedure in which i am trying to fetch values from this table. The SP has 2 DateTime parameters @DateFrom and @Dateto. This SP is called from a Web page. On the Web Page the user just enters mm/dd/yyyy values for the 2 Date parameters. Therefore the Time portions defaults to 12:00 AM. So when the user passes 6/6/2001 as Date From and 6/6/2001 as Date To values, he doesn't get back the 2 records mentioned above since the Time portion makes the 2 records fall out of the date range.
Is there a way to just do a comparison on the Date portions i.e. give me all the records for 6/6/2001 irrespective of the time. I don't wan't to do individual comparisons for Day then Month and then Year.
Thanks
Sanjay.
Comparing And Filtering??
Sep 1, 2003Hello all,
I'm new to SQL Server so if the following sounds stupid then apologies. I am trying to design a query which compares columns and filters according to the result of the comparison. We are a UK based charity that provides financial help to families with disabled children (www.familyfund.org.uk). We have a large database (250,000 entries) which we know contains some duplicate/split files from a recent migration. We need to identify these files but not delete them. Currently I am using the following:
SELECT dbo.Families.famId, dbo.Address.street, dbo.Children.childId, dbo.Address.postcode
FROM dbo.Children INNER JOIN
dbo.Families ON dbo.Children.family_no = dbo.Families.famId INNER JOIN
dbo.Persons ON dbo.Families.famId = dbo.Persons.famId INNER JOIN
dbo.Address ON dbo.Persons.addressId = dbo.Address.addressId
WHERE (NOT (dbo.Children.eligStatus IN (3, 4)))
GROUP BY dbo.Children.childId, dbo.Address.postcode, dbo.Families.famId, dbo.Address.street
HAVING (dbo.Address.street IS NOT NULL)
ORDER BY dbo.Address.street
Obviously this returns all 250,000 records and then we have to search manually. We would like to run a query which compares families.famID to address.street so that where famId has more than one address attched it is returned to the results grid. Does this make sense? is it possible? Any help would be gratefully received
Thanks in advance

Comparing Two Databases

Sep 28, 2005Hey all,
Trying to compare unique fields from two databases.
Basically what i'm trying to do is get all of the id's out of one field that don't exsist in the 2nd database.
so I have this query
Code:
select Distinct Id
from table1
where ID!= (select Distinct ID from table2)
I'm getting this error
Server: Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Now I don't understand why because then I query
select id from tables 2
I only get 1 value for each row.
Now you should know, the two columns in either table are different, in one of them the first value is "1" in the other the first value is "00000001" although I don't think that should effect anything.
Any idea's?
Thanks

the format of the stdate and dateEntered (a datetime datatype) looks like - 25 Aug 2005
right now, the query simply uses the first 2 letters of the date to fetch the record. That would not do the job as i want the thing to compare the whole lot! not just the 1st two letters...

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,

Basically I have two tables,
AgentSchedule
AgentPunchData
These tables both contain agent names.
The schedule table has a column called "SHEND" which is a DATETIME datatype which identifies when an agent shift should end.
The entries all have a date attached which means nothing, for example "12/30/1899 9:00:00 PM"
The PunchData table has a column called "LOGOUT" which is also a DATETIME, the entries will have the real date and look something like this: "3/28/2008 9:23:00 PM"
I need to strip the date out of these functions so I can compare the times. I need to query the databases and return any instances where the LOGOUT time is > the shift end time (SHEND).
So far nothing I've tried has been successful. I'm completely stumped, I've tried so many different things and nothing compares the two times correctly. SQL DATETIME is the biggest pain in the ass, I wish we had SQL 2008 so I could just use TIME.
