Comparing SQL Data Against XLS
Apr 10, 2007
Hello,
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

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])

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 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

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 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.

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.

Can anyone tell me how a program like this might work:http://www.red-gate.com/products/SQ...mpare/index.htmI want to backup databases into a central repository but I only wantthe records that have changed for that day. 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:)

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!

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.

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!

I'm trying to come up with an elegant, simple way to compare twoconsecutive values from the same table.For instance:SELECT TOP 2 datavalues FROM myTable ORDER BY timestamp DESCThat gives me the two latest values. I want to test the rate ofchange of these values. If the top row is a 50% increase over the rowbelow it, I'll execute some special logic.What are my options?

It 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
B01
6
A01
7680
12345
C01

98765
Y15
2500
Y15
3000
98765
X10
1200
Y15
3000
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:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345

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?

I am wondering how I would create a SELECT that will select the most recent date from one of two tables. 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.
Can anyone help?

Hi All,
I have a database field (datestamp) which returns the date the records were inserted into the database. The datestamp was created with the now(); function in .net and is in the following format: 5/23/2006 2:27:45 AM
I basically want to return all records that were inputted more than 28 days ago. I have had alook though some other posts and below is the closest query that i could find but unfortunately it does not work for me.
SELECT id, datestampFROM table WHERE datestamp > DateAdd(d, 28, GetDate())
Thanks in advance,
