How Can I Connect To Two Databases?
Aug 3, 2007
hello,
i want to make a relation betwen one of my tables and the user tables (to take it's unique ID), if there isn't any methode to do that without using the two databases(ASPNETDB - automaticly created when a user registers, and MyData), how can i connect to both databases? here is my connection string, but what should i do?<connectionStrings>
<add name="SiteConnection" connectionString="Server=(local)SqlExpress; Integrated Security = True; Database = MyData" providerName="System.Data.SqlClient" />
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|MyData.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
</connectionStrings> thank you

I designed the AlwaysOn wrong, but every time we fail over from primary server to another server, my applications cannot connect because the sql logins cannot connect to their default databases. Once I run the command to link the login with the user in the default database then the users are able to connect. Did I do something wrong when designing AlwaysOn?

Hi, If you have 2 databases with the exact same table columns, and in the first database in a table column the indentidy seed starts at 1 and finishes at 32,000 can you attatch a second database so that the indentity starts at 32,001and carries on. What happens if you create a site and run out of disk space and need to attach another database which is located on another server??? I am really confused about this.Hope someone can give some links to some articles about this as I can't find any information about it.How can this be done? Thanks

Hello!
I have a problem connecting to two mssql databases to select data in one php script.
- I made two different include file to connect to the two db's
- in the php script I include both files
- my first select statement look as follows:
$msquery1 = "SELECT Dateiname FROM database1.dbo.table";
$msquery1 .= "WHERE AuftragNr = '$jobNr'";
$msresult1 = mssql_db_query($msquery1,$link1);
while ($mszeile1=mssql_fetch_array($msresult1))
{
...
echo "<td>$mszeile1[Dateiname]</td>";
...
}
mssql_close ($link1);
- the second select statement in the same file:
$msquery = "SELECT AdrName FROM database2.dbo.table";
$msquery .= "WHERE AuftragNr = '$AuftragNr'";
$msresult = mssql_db_query($msquery,$link);
while ($mszeile=mssql_fetch_array($msresult))
{
...
echo "<td>$mszeile[AdrName]</td>";
...
}
mssql_close ($link);
I am totally stuck - when I take one select out an run the other one separately I get the field contents I ask for.
Can anyone help - I searched this forum and many more but I cannot see where I go the wrong way.
Thanks very much in advance.

In my IPAQ, I have been using SQL CE for databases with various sizes without any problem. I am creating the databases on my desktop using VS 2005. After I moved to VISTA, I have upgraded my VS 2005 to SP1 and SQL CE to 3.1. My databases which were created before worked without any problem. After I have created my databases via 3.1 on the desktop and moved them to Mobile, I had problems.
1. I specify Max database size parameter as the size of the database
2. If the size of the database is smaller than 16 then I specify 128
3. If the database is old version then program runs without any problems whatever the database size is
4. If the database is created with 3.1 and size is small (20MB, 60MB, etc) no problems arise
5. Ä°f the databse is created with 3.1 and size is large (133MB, 174MB) then dbconnection.Open() command runs indefinitely and program hangs up .
My IPAQ runs "Microsoft Pocket PC Version 4.20.1081" and desktop runs VISTA Home Premium. I have installed VS 2005 SP1.
Thanks for any help

Good morning all,
I need to create a new table on a SQL Server 2005 Database, but the data needed for the table is kept in different databases on different servers.
Half the data is on the SQL 2005 database, so that shouldn't be too much of a problem, but the other half is on a SQL Express database on a different server, is it possible to write a T-SQL query to retrieve this data on the other server?
Normally I use a create table + insert into kind of query to create custom tables but I don't know how to connect to the SQL Express server/database using T-SQL (if it's possible at all?) to do this.
Any tips, hints, ideas very welcome. Please use small words and short sentences.
Thanks,
Paul

Dear Readers,Is it possible, like in Access, to link to tables in other SQL databases that are on the same server? I have a query that I originally had in Access that queered from multiply databases. It did this by having those other tables in the other databases linked to the database that had the query.

I try to import my SSIS packages which are created using the Business Intelligent studio into SQL server 2005 but I cannot do that.
I am running SQL server 2005 enterprise edition.
Also when i tried to connect to Integration services using Object explorer, it only prompt me for server name. I cannot change the username and password which is disabled.
Then how am i supposed to connect to Integration services on a server in this case?

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
These are my values in my Java app web.xml -
<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.
And yes, the port is 1055 - I checked to find it.
I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).
Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

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

I have created a site which now has two databases. Firstly is the ASPNETDB.MDF which I beleives get set to manage the security, logon/Roles that I have on my site. The second dataabase "MyDatabase" is one that I have created for all my data withing the site. I would like to combine this to one Database for simplicity and cost. Now I can't see the ASPNETDB.MDF when I use SQL Manager 2005 and I can't see how to change the set up of ASP.Net Configuration if I was to just use mydatabase. Any suggestions

Hi, I have my site set up, but have had difficulty using the data gathered by the aspnet.mdf. I wanted to use the email and username columns from the membership table to send newsletters automatically from the database(but that's a whole other post)I also have my own databse, which will be populated by information gathered from the website, so is currently empty. I'd like to take this opportunity to say that i don't think there's enough information given on how to populate a blank database from a website application. Most tuorials etc are concentrated on retrieving and displaying data, which is all well and good, once you actually have data to play with!I don't need two databases, so can I add tables to the aspnet.mdf ? But then what about relationships etc? I won't damage the current relationships by adding new ones? On the other hand can i copy the aspnet.mdf into my own database, and then assign the relevant permissions to that db? Any help would be greatly appreciated-in language for newbies please! I am relatively new to .asp.net/Visual Basic/ and SQL. It's a steep learning curve!Also....I have used create user wizard, login, password recovery etc within my site, the data is inserted into the correct db tables-without using an sql datasource for some reason...? is that right?I have also created a wizard to collect some more data (because i couldn't work out how to insert the data from the extra steps in create user wizard, into my own database) but when i click submit the data is not inserting into the specified table - (yes the connection string is fine, insert and update has been selected from the advance tab in connections wizard). Would this/could this be because i have assigned a 'finishbutton url'? should i use a Response.Redirect("blahblah.aspx") instead?

Hello,
I’m using VB6 as the client and MS SQL Server 7 as the database. The company I’m consulting for has a proven track record for marketing and getting millions of customers. The parent company would like to create two new companies selling the same product; with 1 million customers per company. How many records can MS SQL Server 7 handle? I’ve been told it can handle 4 terabytes. What does 4 terabytes translate into records? I have already set up an application for company #1. Should I put company #2 in the same MS SQL Server database? Or should I put company #2 in a different database? My VB Application and SQL Server database were designed to handle multiple companies selling the same product. For performance sake; would it be better to separate the databases? Any suggestions? Is anyone currently using MS SQL Server with 2 or more million records?
Thanks,
Denise

I am presenting using MS SQL 6.5 and have used up all my (VDEVNO) device numbers (1-255). Will I have this problem when I migrate to SQL 7? I understand SQL 7 does not use a device when creating databases, so what
is the maximum number of databases I can create in SQL 7?
Thanks in advance.

Hello,
Is it possible to restore a 6.5 database to a 7.0? I backup the entire 6.5 database to a BAK file then tried to restore it to SQL 7.0 but it didn't work. SQL 7.0 states that the disk device is not a valid Microsoft Tape Format backup set.
We have an application that was developped long long time ago by a old team and I don't want to upgrade the server. I tried to build a second 6.5 server (new hardware) but I couldn't restore the database as SQL 6.5 states that the server is in single user mode. I don't know how to switch to multi users mode. The database I want to restore is not in DBO or single user mode.
Any help will be appreciated.
Thanks.
Toan.

I'm writing an app in vs2005 using sql express. This may be the wrong forum for this question, but here it is. I'm going to have several tables: Seven for Customer information, six for Employee information, 15 for Misc Definitions (status types, skill types, discipline types, gender types, etc.) and 10 for Scheduling information. This is a total of 38 tables.
Is there any advantage to having four databases, one for each type, or should I put all 38 tables in one database and add relationships to everything?

I have assembly with several UDT. Let's call one of them - T. I have loaded assembly to 2 different databases. Let€™s call them €“ d1 and d2. I also have function F(), that returns type T.
I want to run such statement:
use d2
declare
@v t = d1.dbo.F();
If type T in d2 lies in schema dbo, then such statement will work without any problems. But if I want to register T not in dbo, but in some other schema (let€™s call it S), I will have an error:
Msg 206, Level 16, State 2, Line 1
Operand type clash: sysdb.ssma_oracle.Record is incompatible with t1.ssma_oracle.Record
Only conditions for CLR UDT, that I found, were:
When you use user-defined types across databases, you should remember the following:
· The types must have the same name, including the same CLR name, and must be implemented through the same assembly in both databases. Assemblies in two databases are identical if they have the same name, strong name, culture, version, code access permission set, and binary contents.
· You must have SELECT and EXECUTE permissions on each user-defined type column referenced in the query. These permissions are checked with regard to the database in which each column is defined.
· If a type that is implemented in one assembly calls a method in another assembly, the cross-assembly call is checked in the same way as if the user-defined type query were issued without crossing databases.
But I still have the same error. Why?
