查询同一个表以获取MS SQL Server中的数据库列表

Question

This is my first time posting on SO, so please go easy!

I'm attempting to write a SQL script that queries the same table for a list of databases in a single SQL Server instance.

I have successfully queried the list of databases that I required using the following, and inserting this data into a temp table.

Select name Into #Versions
From sys.databases
Where name Like 'Master%'

Master is suffixed with numerical values to identify different environments.

Select * From #Versions

Drop Table #Versions

The table name I am trying to query, is the same in each of the databases, and I want to extract the newest value from this table and insert it into the temp table for each of the database names returned.

I have tried researching this but to no avail. I am fairly comfy with SQL but I fear I could be out of my depth here.

Answer 1

You can do the following. Once you have the list of your databases, you can build up the query (you need to edit it for your purpose).

Select name Into #Versions
From sys.databases
Where name Like 'test%'

declare @sql as varchar(max) = ''
select @sql = @sql + 'INSERT INTO sometable SELECT TOP 1 * FROM ' + name + '..sourcetable ORDER BY somedate DESC; '
FROM #Versions

exec (@sql)

Drop Table #Versions
