Compare Data
Jul 23, 2005
I've created two tables. One table (Classes) stores data about classes
that we offer. The Classes table stores the class id (classid) and the
max number of students allows (maxstudents). The other table
(Students) stores student data and the class they register for.
When a user registers for a class, the classid column data from Classes
populates the class column in Students.
I'm not sure how to count the number of students who registered for
course X, subtract that from the max number of students in the Classes
table, and display that the class if the max is reached either in a
warning dialog box or as text on the page.
I'm also populating a drop-down field on the registration form with the
class information from Classes. Confused yet?
I don't know much about SQL or .ASP. Any help is appreciated.

I am using MSSQL v8 (if that matters)
The data looks like the following
---------------------------
| PBP 20070420 2:26pm |
---------------------------
Now the data in this field is not uniform it can be blank, a sentence or have a different pre fix, instead of PBP, but the date will be YYYYMMDD when it is supplied.
I need to find all the dates that are within the last 10 months. How do I perform this task?

Hi all,
Newbie here. I was wondering if any of you gurus could answer a question for me. Here is what I need to do (and I stress need):
I have 2 tables.
Table A has 3 columns, column 1 is unique customer numbers, column 2 is ticket numbers, column 3 is empty records.
Table B has 2 columns, column 1 is unique customer numbers (same numbers, although not the same order as Table A) , column 2 is invoice numbers.
I need to compare Table A where records in column 1 match records in column 1 in Table B. Where the records do match, I need to copy the records from Table B, column 2 to Table A column 3.
Can anyone here help me with this, please? It would really get me out of a jam with this, since it is the last step I have to take to finally get this new app rolled out.
Thanks a lot.
Mark

I have a billing database with patient names in it. I received a tab delimited file from insurance plan of our roster of assigned patients.
I now want to compare the insurance roster to our database to see who is missing.
The roster is layed out like this (info jumbled to protect privacy):
Eligibility List Sample
Last Name First Name Date of Birth Gender Insured ID VW Acct #
ALLEN CARRIE A4/16/1939FDH36664A572576-02
BAKER AMBER S11/24/1956FFXI2824C596439-02
BARKLOWLOREN R12/15/1956MKVF0092A588878-01
BRENNANPATRICIA A 1/14/1959FFXI8763A549675-02
BROWN MARTHA E8/14/1967FBD65508A366963-02
CALDWELL MICHAEL V 12/19/1969MLR500N2J595087-01
CLARK CYNTHIA A4/24/1971FVO600M8O596011-02
DEMPSTER SCOTT A 2/21/1976MCC85242A573371-01
DUNNE ANNETTE M10/26/1976FAE88375D598423-02
DUNNE CHRISTOPHER M 8/1/2021MBV81536A598423-01
I have loaded the text into an Excel Spreadsheet to work with it.
I was able to query our patient profile data base to get people with this insurance plan...but of course the data is never an ideal match.
For instance, some of the roster patients above have Middle Initials Concatenated to the First Name. In my database it is a mixed bag of missing initials, initials concatenated to first name or initials in separate Middle field. Thus a strict match on name is not going to work.
Date of Birth should hopefully be valid between both data sources.
Probably the best source of data to validate on would be the VW Acct# as I trust this to be the same in both sets of data. However in my patient data base it is buried in a note field preceded by a "Vital Works ID: " and then the number 602659-02. Generally it is the first part of the note field, but there could be additional notes preceding or trailing this Vital Works ID info.
An example of the query I was able to pull from the patient data base is as follows:
LastFirstMiddleDate of BirthGenderNotes
ClarkLawrence J9/7/1955MVital Works ID: 7575-01
ClarkKayleeann NULL1/3/1955FVital Works ID: 7575-02
ColeCodyNULL8/19/1948FVital Works ID: 8771-02 snt ref req to ohms for impact appt tbs Sent ref req back to ohms for Impact-DX.
CreaseyWadeL7/9/1988FVital Works ID: 602659-02
KennyRoyJ2/27/1953FVital Works ID: 602679-02
UttJannieC4/11/1984MVital Works ID: 602715-01

YankeeDonald E10/27/1996MVital Works ID: 602762-03
YankeeStephana A4/4/2001FVital Works ID: 602762-04
How could I now construct a query that would tell me what patients were in the eligibility roster that didnt have a match in the patient database?
I would like to then save that to Excel or somewhere that I could print it out from so I can have someone up date the database.
Thanks for your help.

Does anyone have an opinion on specific “data comparison tools�?
We are looking for something to use in our test or dev environments that will be able to compare snaps shots of the data in a database before verse after a test event.
We have been able to record and compare data in specific tables but are learning that other tables were also being changed that we didn’t track. We want to be able to see all changes to a database.

I am trying to determine the changes an application makes to a database.The plan is to copy the existing schema (active) to a reference schema, runthe application and then diff the table data between the reference and thea active schema. I have found one software vendor who has a tool to dothis, but it will only do one table at a time (interactively); I have morethen 300 and will run this a few times.One other way of determining the changes, I guess, would be to log all sqlstatements (in order), but I don't know how to do this (either).Any pointers would be greatly appreciated.Leo

Using SQL data compare i get the following error message:Could not allocate space for object '(SYSTEM table id: -701903460)' indatabase 'TEMPDB' because the 'DEFAULT' filegroup is full.The comparison is being run on one server between to databases. It hasbeen run several times but each time we get that error message, thetable ID number tends to change each time. We also had a problembefore where the 'TEMPDB' did not have enough space in its log filebut that was fixed by allowing the database to expand in size.

I am trying to QA data being put into a SQL database by an outside source (from Excel) and therefore need to compare two (for the sake of simplicity) tables within a database to one another.
The two tables should contain the same data, and the QA process is meant to find and report any discrepancies. The column names are slightly different.
My question then is, is it possible to write a simple SQL query which will compare the data from the two tables and select only those rows where the data in any given column does not match? My data is mostly text, not numerical.
I'm very new at using SQL and my knowledge of the query syntax is very basic.
Thanks for any help in advance!

We will need to routinely import only changed data from an Oracle data base into a SQL database.
So we need an agent that will
1) Compare data in both databases (From disparate tables)
2) Import only that which is changes or new.
I am new to SQL server administration and am looking for a best practice method that we can be run on a weekly basis.
I am open to using third party software solutions, but would prefer a native MS SQL 2000 solution.
Can someone point me in the right direction?
Thanks.

I have 2 databases( "A" + "B") with identical number of tables and identical number of records for each table. There are also identical number of fields pre record per table. Table A has had the sensitive data within the fields scrambled.
I need to know if there is a way to read down each DB table by table, record by record, field by field and compare the data values. If they are different I need to output the Field name, the data value and the Table name from the Scrambled Table (lets say its "A").

817159784 4.1547006
817159792 3.56576013
I need to extract the corresponding price from the following table:
Zone MaxWeight Price
---------------------- ---------------------------------------
31 1.70 7.14
31 2.20 8.76
31 3.30 9.47
31 4.40 9.69
31 5.50 10.61
31 6.60 11.05
31 7.70 11.49
31 8.80 11.93
31 9.90 12.37
31 11.00 12.81
31 12.10 13.23
In this case, the 2 first rows should give a price of
1) 7.14 (weight between 0 - 1.70)
2) 11.93 (weight between 8.80 - 9.90)
How can I do that with a query?

Okay all I have a problem. I have two list of adresses and phonenumbers. I do not have control over the contents of the lists The onlyunique field between the two is the phone number. I need to be able toinner join the two lists on phone number.This would normally be straigt forward but the problem is that they areformated different and one of them does't even have a control on theformating.*Phone numbers are US phone numbers only.The one list (table) that does have a control uses this formatAAA3334444where AAA is the area code333 is the 3 digit prefix4444 is the four digit suffixthe second list (table) does not have any standardized formating andcan be filled with extraneous spaces, parentheses and dashes not tomention the leading 1 in some instances.I thought that I could do some kind of regular expression to do acomparison but I havn't as yet found a good resource to tell me how todo it or if it is even possible. Or maybe break up the one I know hasa standardized format into something like this:'%AAA%333%4444%' and doing my comparison that way. however It is veryimportant that only those list items in both list that are truly thesame place be listed.suggestions and solutions are apreciated

Heres my sql statement which checks this:
sub select2Cmd( )
'========================================================================================
SET objrs5= SERVER.createObject( "ADODB.recordSet" )
dim sqlStatment
sqlStatment = "SELECT * FROM [table2] WHERE [Name] = objRs2(Name) "

I am trying to compare the data from 2 different servers. It is the same table. I did a select * and put the data into 2 different text files. I then used the Windows NT findstr utility to compare them to find the differences. I used the command findstr /v /i /x /g:file1 file2 > file3, where file1 is the larger table, and file2 is the smaller one. I want to find the records in file2 which are different or do not exist. I recieved no data back. I have ASCII characters in the text files. My question is does anyone know of a better way to do this, or how to make this command work?

Hi all,
Does anyone know any open source tool out there for these purposes?
1. Compare data rowcounts from two databases of the same structure.(On different servers).
2. Compare the structures of two databases.(On different servers).
3. Tool a developer can run on his/her desktop to capture a log of the database that his application is hitting.
Again all, I am new to the database world. Thank you for all assistance.
