Join 2 Tables Exist In Two Databases
Nov 23, 2005
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??
Best Regards,
Manolis Perrakis

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.

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

I have this sql statement:select A.field1,B.field2from table1 A,table2 Bwhere A.field1=B.field2If there is no match, I still want to produce a line of output withfield2 showing a blank. Ordinarily I could simply do an outer join.But because I have more than two tables in my real query, it won't letme.So instead, I tried this approach:select A.field1,B.field2from table1 A,table2 Bwhere A.field1=B.field2or not exist(select 1 from table2 C where C.field2 = A.field1)But now I get this error:--------------Incorrect syntax near the keyword 'select'. Incorrect syntax near ')'.Statement(s) could not be prepared.--------------Any hints as to what I need to fix?Thanks.Dennis HancyEaton CorporationCleveland, OH

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 have two tables:
1. tblProducts
columns: ProductID, ProductName
2. tblProductCodes
columns: ProductID, CustomerID, ProductCode
The 2nd table is for storing product codes for customers, in other words, one product can have different ProductCode for different customers. But some customers do not have ProductCode for a ProductID.
I want to create a query to return all the Products and its ProductCode (null is valid) for a specific customer.
I tried:
SELECT dbo.tblProductCodes.ProductCode, dbo.tblProductCodes.CustomerID,
dbo.tblProducts.ProductName,
dbo.tblProducts.ProductID
FROM dbo.tblProducts LEFT OUTER JOIN
dbo.tblProductCodes ON dbo.tblProducts.ProductID = dbo.tblProductCodes.ProductID
WHERE dbo.tblProductCodes.CustomerID = 2
But the query left out all products that does not have ProductCode value in tblProductCodes table for CustomerID = 2. I want all the ProductName returned from query and render null or empty string for ProductCode value if the code does not exist in tblProductCodes table for the customer.
Any help is highly appreciated.

I have table Products and Orders that has the following columns:
table Products: ProductID, ProductName
table Orders: OrderID, ProductID, OrderDate, Quantity, Price
The Orders table contains orders placed on all the dates. I want to obtain a list of orders for a particular date, if there is no order for a product on the requested date, I want to return null values for the Quantity and Price fields.
I tried the following select statement:
select Products.ProductName, Orders.Quantity, Orders.Price from Products left join Orders on Products.ProductID = Orders.ProductID where Orders.OrderDate = '10/16/2004'
Where, there are a total of three products (A,B,C) in table Products. Product-C has no order on 10/16/2004, but I want it to return :
ProductName / Quantity / Price
Product-A 5 1.89
Product-B 6 2.43
Product-C null null
Obviously, my sql statement won't work becaue the where clause will filter out Product-C.
Could anyone help me figure out how to modify my sql code to get the resultset I want?
Thanks in advance.

Hi guys,
I'll appreciate any help with the following problem:
I need to retrieve data from 3 tables. 2 master tables and 1 transaction table.
1. Master table TBLOC contain 2 records :
rcd 1. S01
rcd 2. S02
2. Master table TBCODE contain 5 records:
rcd 1. C1
rcd 2. C2
rcd 3. C3
rcd 4. C4
rcd 5. C5
3. Transaction table TBITEM contain 4 records which link to 2 master table:
rcd 1. S01, C1, CAR
rcd 2. S01, C4, TOY
rcd 3. S01, C5, KEY
rcd 4. S02, C2, CAR
I use Left Join & Right Join to retrieve result below (using non-ASNI method) but it doesn't work.
Right Join method:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A RIGHT JOIN TBCODE B ON A.CODE = B.CODE
RIGHT JOIN TBLOC C ON A.LOC = C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
When I use Non-ASNI method it work:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A, TBCODE B, TBLOC C
WHERE A.CODE =* B.CODE AND A.LOC =* C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
Result:
LOC CODE ITEM

S01 C3 CAR
S01 C4 TOY
S01 C5 KEY
S02 C1 NULL
S02 C2 CAR
S02 C3 NULL
S02 C4 NULL
S02 C5 NULL
Please Help.
Thanks.

When I am initializing a transactional replication from SQL 2005 to Oracle 10g, SQL tries to drop tables that don't exist. The properties option for the articles specifically states "if the name is in use:". The name is not in use, yet SQL still tries to drop non-existent tables, which causes the replication to halt. Anyone seen this before, or have any ideas what to do about it?
Thanks!

I have two tables that will not drop in a Database. I'm running SQL 6.5 on a Compaq Proliant.
Symptoms: Both tables show up in sysobjects, sysindexes, and syscolumns. Both allow SELECT, sp_rename, and truncate, but just hang ISQL or the Enterprise Manager when I try to drop them. I ran a DBCC CheckTable on them with no errors reported. Any ideas??

I have two SPs, call them Daily and Weekly. Weekly will always callDaily, but Daily can run on its own. I currently use a global temptable because certain things I do with it won't work with a local temptable or table variable.I have been trying to get code so that if the table already exists, itjust keeps going and uses it, but creates the temp table if it doesn'texist. Unfortunately, no matter how I try to do it, it always attemptsto create it, raising an error and breaking the code.create table ##load_file_log (id int identity(1,1),contentsvarchar(1000))insert into ##load_file_log (contents) values ('test record')IF object_id('tempdb..##load_file_log') IS not NULLprint 'exists'ELSEcreate table ##load_file_log (id int identity(1,1),contentsvarchar(1000))select * from ##load_file_logdrop table ##load_file_logIf I change it to IS NULL, the same error occurs (Server: Msg 2714,Level 16, State 1, Line 7There is already an object named '##load_file_log' in the database.)I have found one way to do it, but it seems a bit...clunky.IF object_id('tempdb..##load_file_log') IS NULLexec ('create table ##load_file_log (id int identity(1,1),contentsvarchar(1000))')I'll use that for now, but is there something I missed?Thanks.

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,

Function GetConnectionString() As StringDim ConnectionString As String = ConfigurationManager.ConnectionStrings("MainWeb").ConnectionString

If i > 0 Then sql = sql + " OR "
sql = sql + "(CoCInfo.CoCName + ' ' + AmendmentInfo.AmendmentName) LIKE '%" + words(i) + "%'"

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.

Hi everyone.
I am stuck on this for quite a while. Lets say i have 2 tables.
Table 1 with these columns:
Serial_Num
Product
Price
Table 2 with this column only:
Product
I need to create a VIEW that will show me all the the data in Table 1 but only for the column that exists in table 2. Example:
Something like this:
select (all the columns from table 2)
from table 1
I need it to be dynamic because columns could be added to both tables anytime.
Thanks.

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 get all distinct values from 10 different tables that exist in the field [favoritesport] And each table holds close to 50K records so I am looking at 500,000 records to get distinct values for. Would the fastest, less intrusive way of achieving this be to just create a UNION ALL so run
Select Distinct([favoritesport]) from table1
Union
Select Distinct([favoritesport]) from table2
Union
Select Distinct([favoritesport]) from table3
etc etc etc

I have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores'
storeid doc article storeid doc article
ALL 0010 001 101 0010 001
ALL 0010 002 101 0010 002
ALL 0011 001 102 0011 002
ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".

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.
Thank you.
