Capturing multiple error messages from a single statement inside TRY CATCH

Question

I am running a batch of statements on several columns and tables and want to retrieve information on what errors occur.

The statement is a type change (varchar to nv

Depending on your needs and the permissions of the account that you are running this script under you may be able to use DBCC OUTPUTBUFFER(@@spid).

I came across this idea when reading Erland Sommarskog's Error Handling article. He links to a procedure spGET_ErrorMessage.

Unfortunately this didn't quite work in my test script on SQL Server 2008 though so I'm not sure if the buffer format has changed but it might get there with a bit of tweaking!

CREATE TABLE #foo
(
c INT DEFAULT(0)
)
ALTER TABLE #foo ALTER COLUMN c VARCHAR(10)

GO
EXEC spGET_LastErrorMessage

Actual Output

Msg 5074, Level 16, State 1, Line 2
The object 'DF__#foo___________c__6DCC4D03' is dependent on column 'c'.

    Msg 4922, Level 16, State 9, Line 2
    ALTER TABLE ALTER COLUMN c failed because one or more objects access this column.

Claimed Output
