Aug 3, 2007
hi,
i have one database ASPNETDB.MDF created by default when adding a user to my site, and MyData.mds - my database...i want to join the aspnet_Users table with another table created by me (in myData.mds), how can i do that? is hard if i should re-write all the data from myData into the ASPNETDB,i even writed both connectionStrings in the web.config but still with no succes...
is there any trick in the SQL statment? please help me
Hi, I want to get the results of a query between 2 tables that exist in the same server but in 2 different databases. I want this query to be executed in a stored procedure (use the reults in a cursor), or if it's possible to be used in an ado dataset or a simple dataset in Delphi. Can this be done also if the two datases (MSSQL) exist in different servers?? Can anyone show an example of how to accomplish these tasks??
I have a problem in that a database I have created required splitting into three databases. The records were similar but reporting and maintenance differed enough that splitting the data seemed the best option. So now I have three databases that are needing to be updated from one file and I am not sure how to do that. See the illustration below. The Machine table is a one to many to the Job table, the Job table is a one to one with the Run Data.
The first idea was to query the first database if the record was not found go to the next. If no match was found in any table drop it in a reject bucket. Then what about perhaps a lookup table with starting and ending Job ranges. I would query it to find the correct database then do another query to update the record. But then I could have some type of joining table. Not sure how that would look across databases.
The tables I am updating or adding new records to has the same fields, unique key across all the databases. I could make one big table which gets rid of the query to find the correct database to update but I still would have to connect this back to the Job table which brings me back to a join table or index table.
I have a basic sql statement, where I have a usersID, and I want to joing that usersID to another table in another database to get the users first and last names. How do I join across databases... each with a different connection string? Here's what I want.. Select usersID from tableA in databaseA, and usersFirstName, usersLastName from table B in database B where the usersID from tableA = the usersID in tableb.
Hello, I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services? Thanks
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 need to do a inner join on tables from two separate databases. I understand that you can do this by using this type of syntax: select a.col1, b.col2from db1.dbo.tab1 a, db2.dbo.tab2 bwhere a.col1 = b.col2however, how do I reference the two databases in the following code? Thanks, Tim

My environment:XP Home, VWD, SQLEXPRESS.A purely local setting, no network, no remote servers. I try to do a JOIN query between tables in the membership ASPNETDB.mdf and one table in a self created 3L_Daten.mdf. After dragging the tables into the Query Design window and connecting them VWD creates this query (here I added the control declaration): <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringAspNetDB %>" SelectCommand="SELECT aspnet_Users.UserName, aspnet_Membership.Password, aspnet_Membership.Email, aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer, aspnet_Membership.CreateDate, aspnet_Membership.LastLoginDate, aspnet_Roles.RoleName, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Age, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Sex, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Area FROM [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten INNER JOIN aspnet_Users ON [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.User_ID = aspnet_Users.UserId LEFT OUTER JOIN aspnet_Roles INNER JOIN aspnet_UsersInRoles ON aspnet_Roles.RoleId = aspnet_UsersInRoles.RoleId ON aspnet_Users.UserId = aspnet_UsersInRoles.UserId LEFT OUTER JOIN aspnet_Membership ON aspnet_Users.UserId = aspnet_Membership.UserId"></asp:SqlDataSource> THIS WORKS, BUT: As you can see the database 3L_Daten.mdf is inserted with its full path, which is not feasible for deployment reasons. My question: How can I address both databases purely by their database names ? Both have been created within VWD and lie under App_Data. (I tried almost everything, I practiced with the SQL Server 2005 Management Studio Express Edition, I tried linked servers, all without success). Thank you for your consideration.

A customer has messed up while moving their databases. After working for a week they found that data is missing in the database.I have two backups, one from the old server and one from the new server today, they have been working in the new one for a week.
I need to compare these two databases and then update the new database with all data that is in the old one but not in the new database. Join the data in the two databases so to say. Both databases are from the same application so they use the same users, schema and so on.
I need to run an Insert query which pulls data from a table located on server A database AA Table AAA conditional on (or JOINED with) Table BBB in database BB sever B. In SQL 2000 I would simply do the following:
From Server A:
sp_addlinkedserver B
INSERT dbo.ResultsTable
SELECT SourceTable.* FROM B.BB.dbo.BBB SourceTable
INNER JOIN A.AA.dbo.AAA ConditionTable ON SourceTable.RecID = ConditionTable.RecID
sp_dropserver B
What do I need to do to perform the same operation in SSIS world?
Hi, I'm writing an intranet application - a web survey engine.
I'd like to create a new database for each user that creates a survey form... versus creating new tables for each survey.
Memory and disk space is not exactly the problem... just user permissions. If I dump all the results onto one database, doesn't it mean that this user can have access to all other tables(including the results of other surveys??)
Question is, does SQL Server reserve a bunch of memory for each database that I create, thereby hogging up a lot of space if I create more than one database.
Credit for this script really goes to ToddV (see http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=13737)
The following script issues a DBREINDEX command against every table in every database on your server. It can be modified to issue other commands, but this one in particular is helpful as we are migrating about 30 databases from SQL 7 to SQL 2000 (new server) and re-indexing is recommended. Here's the script:
DECLARE @SQL NVarchar(4000) SET @SQL = ''
SELECT @SQL = @SQL + 'EXEC ' + NAME + '..sp_MSforeachtable @command1=''DBCC DBREINDEX (''''*'''')'', @replacechar=''*''' + Char(13) FROM MASTER..Sysdatabases WHERE dbid > 6 -- skip the 6 built-in databases. Remove to process ALL
PRINT @SQL -- Only if you want to see the code you're about to execute. EXEC (@SQL)
Notes: There is a limit (nvarchar 4000) to how big your command can be, so too many databases will halt this.
Hello, Let's say I created some tables in SQL server using the designer. Tables -> Right click -> New Table ->... How would I send someone else the script for creating that table? Or how would I send somebody else the tables? Thanks.
I am using Vista Business with Visual Web Developer and Sql Server Express 2005. I want to be able to access the data from two tables in a query. Both tables are attached to the application. To refer to the two databases I have used the following DATABASE.OWNER.TABLE (specifically TaskMgr.dbo.TaskTable) For both databases I get the error "Invalid object name" What am I missing? Thanks
I would like to know if it is possible to link two databases together (in my case ASPNETDB, and another mdf database) so that I can run queries on those shared tables. For example, I would like to use the uniqueidentifiers from the ASPNETDB tables in my own tables.
Thank you!
(I do use the latest version of Visual Web Developer).
I am using SQL server7.0. I am having two databases ,say database A and database B.Database A is the main database which is used in two /three projects.While database B is created by me for my work.From the database A, I am using the 4/5 tables, which i have copied in to the database B. So, i want to update these tables in the database B as soon as any change (insert,update or delete ) occures on the tables in the database A. That's why I am interested in doing these work.I have tried, but it doesn't work.So, I have placed these into these forum. Is any body is having the trigger, procedure ready for doing these job. then plz,mail it to me
Hey everyone. I am somewhat of a newbie to the database world. I have been given the task of connecting two different SQL databases. Both are Microsoft SQL.
I want some of the tables of one of the databases to be linked to the tables of the other.
I have two databases that each contain the same tables, but different data in the tables. For example, each data contains a table with the same name, arcus, that holds data on our customers. Although the data is different in each table, there is some overlap, particularly in the area of customer number since that is assigned automatically when a customer is entered and serves as the primary key for that table.
To consolidate, I need to merge the two databases. How can I import the data from one table in second database into a table in the first database and append a number to the customer number so that all data will be brought across.
To better illustrate:
database one has an arcus file with a field cusno and contains cusno 1-50 database two has an arcus file with a field cusno and contains cusno 27-58
The overlapping cusno's are not the same customer.
How can I get all the cusno from the arcus file in database two to the arcus file in database one?
I am trying to relate two tables but both are from different databases. I have a database 'Current' which has a table 'case' and another database 'Org' which has a table 'employee'. I want to establish a one-to-many relationship between employee and case. I created a coulmn 'employee_key' in the case table & entered values matching the pkey of the employee table. Then I wrote a query using joins to access the table records.
select Org..employee.pkey, Current..case.assignedengineer, Current..case.pkey from Current..case join Org..employee on Current..request.employee_key=Org..employee.pkey
Although the above query works fine, there is no relation between the two tables of the two databases, I wanted to know if this is the right way to achieve what i want to or is there a way in which i can actually create a relationship between tables of two different datbases. Can anyone suggest/help??? Also, I wanted to know if i can relate 1 table of SQL Server db with another table of Oracle DB. Please help ........... Thanks
My boss has asked me to look into this and I haven't been able to find any information on the web. I hope someone can answer this for me. We currently have a single database that is storing all the user information and transactions. Within the same database we are also logging different types of user activity. If both these tables are heavily used, would it make sense to separate it into different database, one for data and one for logging? Is there any pro or cons of having more than one database? Any opinion or suggestion would be greatly appreciated. I'm the closest thing they have to DBA and I'm really new to this. Thanks.
i have 2 db's that are totally different except that they both have a table users and I want to make it that anytime the user table is updated or added to in one db - that it is copied over to the other db.
HiI'm working on an ASP project where the clients want to be able toeffectively perform SELECT queries joining tables from two differentdatabases (located on the same SQL-Server).Does this involve creating virtual tables that link to another database, oram I completely on the wrong track?Any hints as to where I might find more information (buzz-words, etc.) wouldbe most appreciated.Thanks
