Then Select from the combine results of the temp table eg: SELECT * From #TempICITEMĪnd all together: CREATE TABLE #TempICITEMįETCH NEXT FROM CURSOR_ALLDB_NAMES INTO = 0ĮXEC ('INSERT INTO #TempICITEM (,) SELECT ''' + + ''' DbName, FROM ' + + '.dbo. Then add in the complexities of multi-database calls.Store the results into a temp table eg: CREATE TABLE #TempICITEMĬhange your TSQL select to an Insert Into #TempTable Select eg: EXEC ('INSERT INTO #TempICITEM (,) SELECT ''' + + ''' DbName, FROM ' + + '.dbo.ICITEM') Table SELECT T1.ID, T1.name,T2.ID,T2. If you have access to both databases, and your table keys match, you can join across databases by specifying the fully qualified name : Database. Try the four-table join until you get it right. The key point is that whether the two databases are on the same server. To define the relationship, use the mysql endpoint (unless you have multiple databases). I would suggest that you simplify this setup and put it in a test environment (on one DB). On Dedicated environments, MariaDB is available with Galera for. My understanding is that I can do cross database queries by prefixing the database (s) names. If you just add both tables in the FROM statement and you don't do your WHERE statement properly, you will get into trouble like you are describing. Im currently using IBM Data Studio 4.1 to run queries against DB2 LUW database (s). While I don't know your schema, I would guess that this link should be an INNER JOIN. In your example, it sounds like you are getting the link to work but you have a join issue on the repair_ord field. You just add the server name dot the database name dot the owner name dot the table name.įor example: SELECT firstdb.*, seconddb.*įROM AS firstdb (without some 3rd party ETL or lengthy integration, such as with Linked Server, when using Microsoft SQL), Snowflake allows you to do all of this seamlessly. As for getting data from two different databases, the syntax is fairly simple. Whereas most competing database platforms make it impossible to combine data from physically/logically disparate databases using a single query. I think you might need an INNER or OUTER join to handle the linking. Get-DbaDatabase -SqlInstance 'server1' Invoke-DbaQuery -File 'C:\scripts\sql\rebuild.sql'. Or use PowerShell with the module dbatools and execute it from outside SQL Server. Under Registered Servers right click on the 'Demo App1' SQL Server Group that we have created and click 'New Query': Run the following query: SELECT Username, isActive, SERVERNAME as 'Real Server Name', DBNAME () as 'Database Name' FROM dbo. sql file in order to have ready access to it in the future. Modern, native client with intuitive GUI tools to create, access, query & edit multiple databases: MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Amazon. It is also possible to save a query to a. I think the duplicates issue is not one of joining the two databases but rather in your join in the first place. The easiest way to achieve this is what Viorel-1 stated above -. In MS SQL Server, you can create and run a query against multiple databases using Registered Servers. Here is what my query looks like so far: SELECT RF.REPAIR_ORD, How can I run a single query on two databases? All tables have the repair_ord column in common. The problem is that when I try to link the two tables from the second DB server the query returns duplicates of 1000 or more. I have two databases on one sql server, and I have to link two tables from one DB server to two tables in another DB server to get the info that I need.
