Comparing Two SQLServer Databases

Jul 23, 2005

Hi, does anybody know a nice tool to automatically compare and show
only the structural differences between two databases, this is, the
differences in the columns of a table, constrains, data type, etc.

Thanks

Comparing Databases

Sep 28, 2005

Hey 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

Comparing Databases

Feb 27, 2008



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

Comparing Data In Two Different Databases

Apr 2, 2003

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

Comparing Two SQL Server Databases....

Oct 16, 2007

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.

Size Of SQLServer Databases With Indices

Jul 20, 2005

Hello,I am starting to examine using SQLServer instead of Oracle. I wentthrough the SQLServer import utility to copy tables from Oracle intoSQLServer. I then checked the size of the database.I then started to specify indices for the tables. I did not see thedatabase file size grow all that much. I kept on using the shrinkcommand to make sure that wasted space was removed. I even made surethat minimal free space was allowed.I was rather expecting (from experience with Oracle) that there wouldbe a large growth in the database when addind indices. So what did Imiss? Are the indices stored elsewhere and I missed them? DoesSQLServer handle indices differently so they dont' bloat the databasesize?The size of our data in SQLServer is a key factor in whether we movefrom Oracle, so I need to under how indices effect storage size.Thanks for any help.Bart TorbertJoin Bytes!

Connection To Oracle / Sqlserver / Db2 Databases

Jan 23, 2007

Hi All,

Is there a way in SSIS to change the database connection to sqlserver or oracle or db2 without choosing the connection manager in the source.

For e.g. I ran a package which is reading data from sqlserver and later i want to connect to oracle to read the data but without changing the connection manager in the source.

Basically, i want to find out from you gurus is about a way to switch between databases without changing the connection managers. OR the only way is to make different sets of packages for oracle / db2 and sqlserver sources ?

Thanks,

Class Method Is Smoking Fast When Executed Outside Of SQLServer, Dog Slow As A CLR Function Is SQLServer - Anyone?

May 10, 2007

We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?



Here is the class:






Code Snippet

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;

namespace Predict.Services
{
public static class Foo
{
public static string GetIntradayQuote(string symbol)
{
string returnQuote = "";

HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));

request.Timeout = 1000;

HttpWebResponse response = (HttpWebResponse)(request.GetResponse());

StreamReader streamReader = new StreamReader(response.GetResponseStream());

returnQuote = streamReader.ReadToEnd();

streamReader.Close();
response.Close();

return returnQuote;
}
}
}



When I run call it from a console app it is fine.



I compile it into a dll and then create the assembly and function as follows:






Code Snippet

drop function fnTestGetIntradayQuoteXML_SJS

go

drop assembly TestGetIntradayQuoteXML_SJS

go

create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS

go

CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote

go



declare @testing nvarchar(max)

set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')

print @testing





When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?



Regards,



Skipper.

Problem Unicode Data 0x2300 In SQLServer 2000 SQLServer 2005 Express

Sep 20, 2006

Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))

Insert Data
insert into testunicode (Bez)values('Œ€„¢')
with 2 Unicode characters
Œ€ = 0x2300
„¢ = 0x2122

Selecting the data
select Bez from testunicode
I see
"?„¢"

„¢ = 0x2122 is ok but instead of 0x2300 there is 0x3f

When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'„¢')

and select again voila i see
"Œ€„¢"
Does anyone have an idea?

Thanks

Trying To 'load' A Copy Of A SQLServer 2000 Database To SQLServer 2005 Express

Apr 18, 2008



I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.

I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?

The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.

Thanks!!

Replacing Sqlserver 2000 With Sqlserver 2005 Express

Jun 14, 2006

I have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.

Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.

If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:

server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"

DB name: name of db instance

port: 1433(default)

user and pass.

My attempts so far results in

"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."

and

"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."

SQLSERVER 2005 X64 Linked Server To SQLSERVER 7.0

Jun 20, 2007

Hello people.

I am in the process of planning a server upgrade to sql2005 x64.

I created 2 linked servers: one to a SQL2000 sp4 server and one to a SQL7.0 SP3.

I have the following error when I query the linked servers.
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "Unspecified error".
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "The stored procedure required to complete this operation could not be found on the server. Please contact your system administrator.".
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "IVDM2K". The provider supports the interface, but returns a failure code when it is used.

I am aware of KB 906954.
http://support.microsoft.com/default.aspx?scid=kb;en-us;906954

I applied the instcat.sql on the SQL2000SP4 server and my linked server issues for that one are gone.

However, I ran the instcat.sql script on the SQL7.0 sp3 server and the linked server is still giving me an issue.

Can someone help me find a solution to this?

Hi,
I am new to SQL Server 2005. I tried connecting to my local machine by using my machine name as Server name and then tried running the following query:
SELECT * FROM SYS.Objects. It gives me following error:
Invalid object name 'sys.objects'.

Whereas, if I connect to my local machine using mahcinenameSQLEXPRESS, then the above mentioned query runs fine.

Why is this difference? What is the difference when I login in these 2 different ways.
Any help would be appreciated.

Thanks in advance.

Service Broker Not Working For Restored Databases (SQL 2000 Databases Restored On 2005)

Jan 24, 2006

I just restored my SQL server 2000 database on the SQL server 2005. after this i ran the Service broker sample ("Hello World") on this database by changing the AdventureWorks name to the new database name. The "setup.sql" runs fine. When i run the "SendMessage.sql" i was not getting any rows in the output (The message was not getting inserted into the queue). I checked the Service broker is enabled on this databased using the query "select is_broker_enabled from sys.databases where name = 'newdbname' " It was 1. I even tried the ALTER DATABASE SET ENABLE_BROKER. but it didnt work.

When i tried the sample on a newly created database it worked fine.

Is there any solution to make the restored database to work for service broker.

Thanks

Comparing Dates In SQL

Jan 28, 2006

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?
