I need a T-SQL script to find, for a given view across all databases (they all have this one particular view), which ones contain a specific column and which ones don't. I've tried INFORMATION_SCHEMA, but that appears to be limited to the "current database context" in SSMS. Haven't been able to quickly find something online that solves it...

Your signature line is starting to look more and more like SPAM, Steve. If I didn't know you, I'd mark your post as SPAM.

As to your question, the information you seek is available only at the individual database level. You'll need to write some code that goes through all of the databases.

Thanks for the reply, Jeff... I'll just have to do this manually then, as I don't really have the time right now to write the code...

As to my signature lines, I have two links, and there are supposed to be 3 smiley emojis following the name, and as I haven't made any changes to that signature in quite some time, I can only assume that something in the website doesn't interpret the existing data the same way that it used to, so I'm going to look at it and see if I can fix the missing emojis - only one of them actually appears... as to why the ?'s appear, again, have to make the same assumption, but I will go look at it.

Signature fixed to what it is supposed to be.

Understood that you've not change it in a while. I'm just making a suggestion because it's been like that for a while. 😉 😉 😉

p.s. You could do a "quickie" with sys.sp_MSforeachdb . It's not something that I'd use for production code but it works for a "one off".

Turns out I was chasing an OLD problem... so it was kind of moot once I realized what was going on... Our SSIS package had been ignoring a column entirely, and apparently, that is okie dokie, so the problem no longer exists.

Oh.. and I don't post anywhere near as often as I used to... and it's cause I'm a lot busier than I've ever been, so I hadn't even noticed that the signature was off, and even if I had, it probably looked more like a website issue to me than a signature problem precisely because I had remembered putting exactly 3 smiley emojis in it, without any question marks... and thus I probably mentally dismissed it and moved on...

Here is an answer to the question, just added it for completeness 😉

😎

To query different databases' schema information on the same server, one simply has to use 3 part identifiers, [DATABASE].[SCHEMA].[OBJECT]

USE master;
GO
SET NOCOUNT ON;
GO

SELECT * FROM master.INFORMATION_SCHEMA.COLUMNS     UNION ALL
SELECT * FROM model.INFORMATION_SCHEMA.COLUMNS      UNION ALL
SELECT * FROM msdb.INFORMATION_SCHEMA.COLUMNS       UNION ALL
SELECT * FROM tempdb.INFORMATION_SCHEMA.COLUMNS

Obviously, the user must have access to all the databases.

30 second search https://duckduckgo.com/?q=find+column+name+in+all+databases+sql+server led to the following:

The sp_MSForEachDB procedure is not on my menu, 5 dynamic T-SQL code executions using EXEC, handful of cursors 🙁

😎

Like so much of the old system code, most of what I have reviewed in details, is so bad that I include the names in my static code analysis as a risk on any production system.

Totally understood and, I never thought I'd say this, but this is for a "one-off". I'll invest some time in a better one later. And, I totally agree with the bad "system code" mention. sp_SpaceUsed was one of my favorite examples of how to not write code. They've improved it quite a bit over the last few releases but it could still use a bit of help. To your point, code like sp_MSforeachdb still makes major sucking sounds for the reasons you mention and more. I'd never use it for production code.

What ticks me off about this whole fire-drill is that the old "Enterprise Manager" product would do such a thing just by pressing the {F4} key. Also, the new "version 17 and later" of SSMS has a huge number of regression issues. For example, (a pet peeve for when creating articles and presentations), custom colors are no longer followed when using Copy'n'Paste like they were prior to the "improved" version 17. And there's no documentation on the "version" of RegEx they've decided to use. They do point you to an article about RegEx but half of it doesn't seem to work in SSMS (and I'm being kind there).

Here is some code I had pirated about 6 years ago:

CREATE TABLE #temp_list

(

db_names varchar(500),

tbl_names varchar(500)

)

;

EXEC sp_msforeachdb 'INSERT INTO #temp_list SELECT "?" AS db_names, name AS tbl_name FROM [?].sys.tables'

;

--SELECT COUNT(*)

--FROM #temp_list

--;

SELECT *

FROM #temp_list

WHERE tbl_names = 'LobXFORM'

-- WHERE tbl_names LIKE '%LobXFOR%' /* Use if you don't know the exact name */

;
