Hi,
I'm using the construction:
INSERT INTO #T(_DBName, _LogSizeMB, _LogSpaceUsedPct, _Status)
EXEC('DBCC SQLPERF(LOGSPACE)')
in a stored procedure. Becaus I ran into the 'An INSERT EXEC statement cannot be nested' error I need to create another construction.
Any help is much appreciated!

This worked for me:

--Table

CREATE TABLE #t(dbname sysname, logsize decimal, logspace decimal, status INT)

--Insert

INSERT INTO #t(dbname, logsize, logspace, status)

EXEC ('dbcc sqlperf(logspace)')

--Results

SELECT * FROM #t

Hi John,

Thank you for your reaction.

You're still using the insert into ---- exec construction. If I use this in my stored procedure, the procedure can be executed with succes. But when I try to store the result of my stored procedure in a table:

insert into DataBaseSizeReport exec StoredProcedure the error "An INSERT EXEC statement cannot be nested" results.

I can't do the insert into trick twice.... so that's why one of them needs to be in another construction.

Any suggestions on how to do that?

Can you not have the stored procedure insert directly into the DataBaseSizeReport table? Or you could have it insert into the same temp table and then copy the data from there into DataBaseSizeReport.

The idea is to execute it on linked servers to gather space usage information and store the collected info in one centralised table.... so it would be a nice solution to execute the sp only on the 'master' instance.

You may be able to use OPENROWSET() and substitute the DBCC command in for the <query> to directly insert into the 'master' table.

I did a process similar to yours and used an sp + table on each server (in the SQLDBA database) and a master table on the 'master' server & pulled the data in using a DTS package that driven by a list of servers stored in a table on the 'master' server.
