Comparing One Database To Another For Changes..????
Sep 19, 2007
Hi,
Lets suppose i am having 2 database that is
Database1 and Database2
Then both datbases are same having same number of tables, sp's, vies and etc.
Then wht i have done is i have added two tables in database1 tb23 and tb24, and at the same time i have added one table out of these two table that is tb23 in the database2,
Now i want a querry by using that querry i am able to find out that how many objects are there that are present in database1 but not in database2. Basically i want to do comparison in between two databases.
ANY QUERRY, OR ANY TOOL by using which we can acheive this.....
HOW????
There are two tables in my Database, tb1 and tb2 which both have the same attribute ID. I would like to ensure that there is nothing in ID in tb1 which is not listed in ID in tb2, can anyone help?
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 would be very grateful if someone could help me. I have very little SQL knowledge and would like a push in the right direction:
I have a application that receives GPS lattitude and longitude values. I was originally using file base system where I would load all the points from the file into memory and do the calculations in the software but I now would like to use SQL Server Express.
I have created the tables:
[Table 1] GPS Points: id int Primary key latitude real longitude real desc nvarchar(128)
[Table 2] GPS Locations (comprises of one or more GPS Points from [1] above) to form a boundary: GPS Locations database structure is: locationId int primary key gpspoint1 int gpspoint2 int gpspoint3 int gpspoint4 int desc nvarchar(128)
Table 2 contains up to 4 gps points ids from table 1 and GpsPoints1-4 can be null.
I have created the tables and I have inserted GPS values into both tables.
My problem: I am trying to compare the current Lat/Lon (which are passed into the SQL fuction as two real datatype value) and I want to return all Table 2 locationId's where the current Lat/Lon are withing GPSPoints1-4 area. gpspoint1, gpspoint2, gpspoint3, gpspoint4 reference an id from Table 1. I am not sure how I can do this?
I have implemetned a SQL function that returns all points from Table 1 that are within the predefined radius of 1.5 miles from the current Lat/Lon values passed in.
where 3963.191 is earths radius in miles, radius is 1.5, @LatDec is the current latitude and @LonDec is the current longitude
Uses a lot of Trig and (for me) is quite complicated. This works very well and is very accurate. It also only uses a single table. I want to be able to now look for the current position within a boundary of 3 or more positions from Table 1 and this is where I am struggling?
Also, any suggestions on how I could do this better would be very much appreciated?
hi im trying to code a login page using asp.net, vb.net. i have 2 web-controlled textboxes whose values i want to compare to userID and password stored on a SQL server database called users. When button clicked, call function checklogin.
heres the code:
Private Sub btn_login_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_login.Click
If Page.IsValid Then
Dim usersDS As New System.Data.DataSet
usersDS = checklogin(userID.Text, password.Text)
If usersDS.Tables(0).Rows.Count = 1 Then FormsAuthentication.RedirectFromLoginPage(userID.Text, False) Else error_log.Text = "Invalid Credentials: Please try again" End If End If
End Sub
Function checklogin(ByVal userID As Char, ByVal password As Char) As System.Data.DataSet
Dim connectionString As String Dim dbConnection As New SqlConnection Dim dbCommand As New SqlCommand Dim dataAdapter As New SqlDataAdapter Dim ds As New DataSet
With dbCommand .Connection = dbConnection .CommandText = "SELECT COUNT (*)Â?@AS pass FROM tbl_users WHERE ((tbl_users.userId = @userId) AND (tbl_users.password = @password))" End With
dataAdapter.SelectCommand = dbCommand
dataAdapter.Fill(ds)
Return ds
End Function
Heres the error i get:
Details of exception: System.Data.SqlClient.SqlException: There is a syntax invalid near line {''1
Source error:
Line 75:. CommandText = "declare@userID As varChar; declare @password As varChar; End With .."Line 76:.. line 77:of SELECT COUNT(*) AS pass FROM tbl_users WHERE((tbl_users.userId=@userId)AND(tbl_users.password=@password)) Line 78: DataAdapter.SelectCommand=dbCommand Line 79: DataAdapter.Fill(ds)
ive just started using .net, im a lil lost...thanks for any help. cheers
We're using SQL Server 2000 as back end in our web project. The problem is we've 3 different copies of same database - one each for Development, Test and Production sitting in 2 different machines.
My question is - is there any tool for comparing the objects (tables, stored procedures, etc) ?
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?
SELECT "Name"."FIRST_NAME", "Name"."LAST_NAME", "Name"."EMAIL", "Name"."ID", "Name"."MEMBER_TYPE" FROM "APSCU_PROD"."dbo"."Name" "Name" WHERE Name.EMAIL='marie@bahoo.com' OR Name.EMAIL='markg@ts.com' OR Name.EMAIL='mare@t.edu'
In my main database table I have many fields but the two following fields are my main concern.
1) email_address
2) unsubscribe
In my secondary database table I have one record only.
1) email_address
What I want to accomplish... I want to compare the email_address of the secondary database table to the email_address of the main database table and if it exist, change the value of the unsubscribe field. (or if I can't do that, then delete the record within the main database table completely.)
how 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.
Hi, I have a table with 3 columns inside - record_id (int) - user_id (varchar) - login_date (date) it is a many-to-many relationship table that record login date of users
Now, I want if I want to COUNT the users who login before 31 May 2008, I would use SELECT COUNT(*) FROM table1 WHERE login_date < '2008-31-05'
That's works
But the problem is I want to split the result to - How many people visit the site only once? - How many people visit the site only twice? - How many people visit the site three time?
I have a field in database money. When I enter value for it the amount entered is for example 20.000. How can I compare this value with noraml vaules i.e. like 20 in my search engine. Will I need to convert it to varchar and then compare it or is there some other way. Also if I need to convert it to varchar, how can I do it?

ok ... it was my error mess, but i just wrote this code :
*********************************************************** Dim conPubs As SqlConnection Dim cmdSelect As SqlCommand Dim strSelect As String conPubs = New SqlConnection ("Server=localhost;uid=ggggg;pwd=uuuu;database=eeee") strSelect = "Select username From userpass Where username = '" & usernametxt.Text & "' And password = '" & passtxt.Text & "'" cmdSelect = New SqlCommand( strSelect, conPubs ) conPubs.Open()
if Not(cmdSelect.ExecuteScalar() IS Nothing) then 'findeduser.text response.redirect("welcome.aspx") conPubs.Close() else msg.text="ID or Pass is incorrect!!" conPubs.Close() end if ***********************************************************
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, Jake
Hi , I have three tables T1 , T2 AND T3. T3 is having fields as a combination of T1 and T2 fields.How can I compare T1 and T2 field values with T3 FIELD VALUES.
How 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.
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
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.
select * from independent_investment_certificate_temp
where independent_investment_certificate_temp.ticker_key = 31
and convert(varchar(40), cast(independent_investment_certificate_temp.maturity_date AS datetime),107) > convert(varchar(40), cast('2006-12-10 10:29:50.733' AS datetime),107)
independent_investment_certificate_temp.maturity_date value is '2005-01-21 00:00:00.000' the query above returns a value even though '2005-01-21 00:00:00.000' is clearly < '2006-12-10 10:29:50.733' but why can anyone plz explain.. how can i compare dates stripping tyhem of the time so that all dates on the same day will be equivalent regardless of the time
Hi, i got this query below, which I'd like to use to compare two sets of date...
select count(*) as rec, convert(char(6),dateEntered,13) as dateEntered from EmailTracker where chtype = '1' AND convert(char(12),dateEntered,13) >= '"& stdate &"' AND convert(char(12),dateEntered,13) <= '"& endate &"' group by convert(char(6),dateEntered,13)
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...
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.
i have two databases best and books.Most of the tables present in best are in books except some. i have been given a task to list out the tables and columns of which are present in best database and not in books database.
Pls suggest me the simplest and quickest way to do this. this is very urgent.
I will try to explain my problem as best as possible without going into too much detail.
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.
I have some code that is trying to first find the first date of service that a person visited. Using the min function is not working. Is there another function? Right now I am still getting multiple rows for each person instead of just the first visit.
Then I want to be able to compare the first date of service to the date of birth and determine if the patient first visited before they were 2 years old. I can't figure out how to do this.
select distinct b.person_id,b.date_of_birth,min(a.enc_timestamp) from patient_encounter a join person b on a.person_id = b.person_id where b.date_of_birth >= '20060301' and b.date_of_birth <= '20060531' group by b.person_id,b.date_of_birth,a.enc_timestamp
