xpreaderrorlog doesn't have a column dedicated to the database name, so no, there's no way to filter based on a LIKE statement directly.

there's a pretty good recap of the parameters and usage here:

i would simply stick all the results into a temp table, and then filter the results from there;

something like this looks right to me and my preliminary test:

[#RESULTS]

drop table[#RESULTS]

CREATE TABLE [dbo].[#RESULTS] (

[RESULTSID] INT IDENTITY(1,1) NOT NULL,

[LOGDATE] DATETIME NULL,

[PROCESSINFO] VARCHAR(128) NULL,

[XPTEXT] VARCHAR(max) NULL)

INSERT INTO #RESULTS([LOGDATE] ,[PROCESSINFO],[XPTEXT])

EXEC Xp_readerrorlog 0

SELECT DISTINCT #RESULTS.*

--dbz.*

FROM #RESULTS

left outer join(SELECT name from sys.databases where name like 'D%') dbz

ON CHARINDEX(dbz.name,#RESULTS.XPTEXT) = 0
