Hi
Is there a way of comparing the data contained in two separate databases (on the same server)?
I have two databases: DevDB and DB and all I want to verify is that the data in both are *exactly* the same.
Is there a nifty function to do this in SQL Server?
Thanks

Hi, I would like to know if it is possible to compare data in two different databases (both SQL7.0),
with same exact schema. If possible, how could we do it?
Thanks

I have a Development and Production database and they are a little out of sink. Does any one know of a way to compare two databases (tables, fields, sp) and report the differences? Thanks in advance.

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

Hey guys,
Im busy working on converting one DB to look like another one and I am using a data comparison tool to generate a script that I can hopefully use to upgrade an existing DB.
The problem is occuring with only one table and as soon as the script is run I receive the following error msg in SQL server 2005;
______________________________________________________________________________________________________
'Patient' table
- Unable to modify table.
Cannot insert the value NULL into column 'ClinicCode', table 'DCS.dbo.Tmp_Patient'; column does not allow nulls. INSERT fails.
The statement has been terminated.
______________________________________________________________________________________________________
Now the problem I am facing and I am hoping you could help with is where I can find the .Tmp table. This is obviously a temporary table created, but I have no clue as to how to alter the values of that temporary table in order to facilitate the changing of the table to coincide with the updated table.
Some help would be appreciated in this regard.
p.s. Hopefully I explained the problem sufficiently for you guys to help out!
Thanks in advance
Hi, does anybody know a nice tool to automatically compare and showonly the structural differences between two databases, this is, thedifferences in the columns of a table, constrains, data type, etc.ThanksJ.A.
View 2 Replies View RelatedI want to compare the records in a table on my live database server with the same table that is my test database server. How can I do this?
Note that both databases are mirrors of each other but contain slightly different data and are on different servers.
Hi All,
I wan't to compare two SQL Server databases. i.e., I wan't to check both databases structure and add if necessary.
In my project I am using SQL Express database and now we update some fields in the database. So, if we wan't to update the new versions for those customers who are using old database we need to update the database also. It is not recommanded that to manually add the fields in the database and is time taking too. So, I wan't to compare two databases(old and new) and update the fields in the old database.
Any confusion in my question plz let me know so that I can be more clear.
Thanks for any reply,
Narayana Ayyagari.

I am trying to build various reports that compares data over time. I have one that measures Year Over Year % difference for number of incoming projects. I managed to do that easily by calculating the following
YTDProjects:=if(ISBLANK(SUM('TrendData'[Projects])),blank(),CALCULATE(SUM('TrendData '[Projects]),DATESYTD(CalendarDate[FullDate])))
PYProjects:=if(ISBLANK(SUM('TrendData'[Projects])),blank(),CALCULATE(sum('TrendData '[Projects]),SAMEPERIODLASTYEAR(DATESYTD(CalendarDate[FullDate]))))
YoYDifference:=[YTDProjects]-[PYProjects]
YoYPercProjects:=IF([PYProjects]=0, BLANK(), [YoYDifference]/[PYProjects])
Where Projects is the metric in question, TrendData is the table that contains project data and CalendateDate is the Date Table. But now I am trying to compare the same YTD projects data to number of projects that came in the last 6 months. How do our projects compare to average number of projects that came in last 6 month period.
I tried the the DATEADD function instead but got no luck and data came out wrong!
PrevProjects:=CALCULATE(SUM([Projects]),DATEADD(CalendarDate[FullDate],-1,QUARTER))
For some reason, this also returns blank in my model:
QTDProjects:=TOTALQTD(SUM('TrendData'[Projects]),CalendarDate[FullDate])
I made ahuge load script in SQL Server 2000 as i load data from manytables(select some of each one collumns) into one single table and iwant to test the loaded data against the selected data to make surethat the loaded data is the same the selected datais there a code or tool to make this test or monitoring ?? pleaseurgent ....
View 2 Replies View RelatedHello,
I am looking for some "best practice" information on how to properly setup a comparison of SQL data -vs- an Excel spreadsheet. I've never performed this task before, and will likely have to do more in the future. How can I define the range of cells to be used from the xls? There are over 1000 rows in the xls, so a Select * from dbo.table where dbo.column = 'x' just isn't practical.
Any information/direction that's out there is most appreciated!
Many thanks
Hello,
I need to do a query to compare the same field in two different databases. How can I go about doing that? Can you use an if not exists and how does that work?
I also need to compare two numbers in two different databases and then convert that number to a decimal. For example I need to compare 22940 in one column and 22942 in a different column and insert the value of 2.1 in a third column. How can that be done?
Thanks in advance,
Anita
Hi
I am relatively new to SQL. Basically i am trying to compare data that doesn't match properly. Firstly one set of data has spaces, secondly the first part of the data is missing.
After researching I am going to remove the spaces with the replace and only query the final 8 number - this would dow hat I want but I cannot get it to work.
Here is my code.
Code:
update aleads as a, leads as l
set a.lid = l.lid
where replace(right(a.htel,8), ' ', '') = replace(right(l.htel,8), ' ', '');
Of course this didn't work but I do not know why - or how to actually achieve this.
create table #prints(id int IDENTITY(1,1) NOT NULL,
Printermarkersupplyid varchar(36),PrinterID varchar(10),Description varchar(10),SupplyLevel int,ModifiedDate datetime)
insert into #prints(Printermarkersupplyid,PrinterID,Description,SupplyLevel,ModifiedDate)
select newid(),'P1','D1',100,'2013-08-1 03:28:38.203'
union all
[code]....
my requirement is to get the difference between adjacent rows.ie difference between 2nd and 3rd or 6th and 7th but not 6th and 8th.if difference between 2nd and 3rd is less than zero and 3rd modified date > 2nd modified date,then i should get count as 1 against 3rd row.
I have the following situation. One set of data has 274 rows (set2)and anther has 264 (set1). Both data sets are similar in structure aswell as values for both of them were extracts from the same parenttable. Hope the info would substitute DDL. I need to find the "gap"rows between these two sets.Attempted to run a query likeselect count(*)from set2where not exists(select *from set1)did not yield what I desired. What else to try?TIA.

This program seems to do itefficiently. Does Sql Server, Oracle, etc offer any sort of built inway of doing this via metadata or a similar mechanism?I want to be able to mirror databases in such a way that I dont need tohave the admin password for them. I don't want to alter the databaseschema in any way.The only way I can think off the top of my head is to assign MD5checksum values to rows and then compare the checksums in the masterand copy, however, to do it efficiently, you'd have to save the MD5values as you go, which would involve altering the schema on the mastertable.

I need to compare two tables in two different databases and get data that is only in one table.
Table 1 in DB1 and Table A in DB_A
I need all distinct IDs in Table 1 in DB1 that are NOT in Table A in DB_A
and copy those IDs into Table A.
Is the sql below correct in obtaining data?
Can I add the copy part also to this?
select ID
from DB1.dbo.Table1 aaa
where not exists ( select empID
from DB_A.dbo.TableA bbb
where aaa.ID = bbb.empID)
I'm trying to create some records for a data table (Table1) based on values in another table (Table2).
Table1 has the simple structure of
ID (INT), PolicyID (INT) (this is a foreign key linked to a Policies table), Premium (FLOAT), StartDate (DATETIME), EndDate (DATETIME)
Here is the structure and some example data from Table2
- PremID - PolicyID - Year - Prem01 - Prem02 - Prem03 - Prem04 - Prem05 - Prem06 - Prem07 - Prem08 - Prem09 - Prem10 - Prem11 - Prem12 -
- 000001 - 00000001 - 2013 - 100.00 - 100.00 - 100.00 - 100.00 - 100.00 - 100.00 - 100.00 - 100.00 - 100.00 - 130.00 - 130.00 - 130.00 -
- 000002 - 00000001 - 2014 - 130.00 - 130.00 - 130.00 - 140.00 - 140.00 - 140.00 - 140.00 - 140.00 - 140.00 - 140.00 - 140.00 - 140.00 -
PremID is just the PrimaryKey. Then there's the year, and then a load of float fields, each representing a premium paid for each month of the year (01=Jan, 02=Feb etc).
Now what I am looking to achieve is to create separate rows for Table1 from this data.
Starting in January (Prem01), I wish to record a separate line each time the premium amount changes. The best way of exlaining this is to give an example based on the above data.
For the first row (2013), the premium at the start of the year (Prem01) is 100.00. This premium remains until it changes in Prem10 to 130.00. It then remains 130.00 for the rest of the year (Prem10 to Prem12). For this I would want to create 2 rows of data for Table1. The result should look like below.
- ID - PolicyID - Premium - StartDate - EndDate -
- 000001 - 00000001 - 100.00 - 01-Jan-2013 - 30-Sep-2013 -
- 000002 - 00000001 - 130.00 - 01-Oct-2013 - 31-Dec-2013 -
I'd then repeat this for each record in Table2, so based on the 2 lines I have shown above, the end result would be:
- ID - PolicyID - Premium - StartDate - EndDate -
- 000001 - 00000001 - 100.00 - 01-Jan-2013 - 30-Sep-2013 -
- 000002 - 00000001 - 130.00 - 01-Oct-2013 - 31-Dec-2013 -
- 000003 - 00000001 - 130.00 - 01-Jan-2013 - 31-Mar-2014 -
- 000004 - 00000001 - 140.00 - 01-Apr-2013 - 31-Dec-2014 -
The source data is inherited from another system which I'm trying to change the layout of how the data is recorded to fit in with the target database.
Would it be easier to create a view of some sort from Table2, then use some form of WHILE LOOP to do this?
I 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.
Hi 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?
Thank you inadvance:)
Comparing data and integrity between two tables
I have an entry form allowing customers to enter up to 15 skus (productid) at a time, so they can make a multiple order, instead of enteringone sku, then submitting it, then returing to the form to submit thesecond one, and so forth.From time to time, the sku they enter will be wrong, or discontiued, soit will not submit an order.Therefore, when they are done submitting their 15 skus through the orderform, I want a list showing them all of those skus that came back blank,or were not found in the database.I'm doing this by creating two tables. A shopping cart, which holds allthe skus that were returned, and a holding table, that holds all theskus that were submitted. I want to then delete all the skus in theholding page that match the skus in teh cart (because they are goodskus) which will then leave the unmatched skus in the holding table.I'll then scroll out the contents of the holding table, to show them theskus that were not found in the database.(confused yet?)So what I want to do is have some sql that will delete from the holdingtable where the sku = the sku in the cart. I've tried writing this, butit dosn't work.I tiried this delete from holding_table where sku = cart.skuI was hoping this would work, but it dosn't. Is there a way for me to dothis?Thanks!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Hi,
In a table i have a column named 'Name'. It can have multi lingual data.
I have desinged a query in which i have a statement as
Select Col1
FROm TABLE1
WHERE
NAME IN (@NAme)
But for MultiLingual names is not compared.
I have declared that column as NVARCHAR.
Is there a performance impact (if so, how great is it) when comparing a date to a datetime data type?
An educated guess suggests yes, as there will be a type casting... but then again I don't believe there's an issue when comparing an int to a tinyint and there's an assumption these would play by the same rules?
This has only come about because I'm considering changing the data type used in my standard calendar script and this popped in to my head.
I have an excel spreadsheet that only has email addresses in a single columnar format on it (318 emails). I want to check and see if any of those emails are in the database. Is there a easier way than having to enter 300+ "OR" statements?

FROM "APSCU_PROD"."dbo"."Name" "Name"
WHERE Name.EMAIL='marie@bahoo.com' OR Name.EMAIL='markg@ts.com' OR Name.EMAIL='mare@t.edu'
Hello,
I am designing a distributed application where a central SQL Server 2005 database will need to be synchronized with remote SQLExpress databases via a WebService. Data can be edited at the cental db (by our connected applications) or on the local SQLExpress dbs running on the users machines (by this disconnected application).
Now, how can I use the timestamp column to determine the most recent update. The most recent update to me is not the user that most recently invoked the syncing WebService, but the most recent time when the change was made to the data locally vs the change time at the central server. Because a user could make a change on his laptop on Monday but not synchronize it till Friday. I dont want the Mon data to overwrite data of Tues-Fri being overwritten simply based on assumption that a late sync is infact the most recent change.
The initial data will be downloaded to the local SQLExpress db via the WebService so the timestamp data in the table will come along with it.
When a user modifies data in this disconnected SQLExpress db, can that be compared to modifications on the central db using timestamps to determine if the users data being synced is older or newer than the data on the server? I understand timestamps are incremental values, but are they still sensitive to the users timezone since the central server will be a diff timezone then the user.
I 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!

Can you compare chars stored as ccyymmdd correctly?
Field1>=field2
I was thinking you needed to cast this information as a datetime value before you could do it.
Thanks
