ATENÇÃO: apenas para constar que NÃO me responsabilizo se você testar isso em seu ambiente e apresentar problemas
Vamos pelo básico,,,
Para listar os comandos DBCC: DBCC HELP(‘?’)
Para uma ajuda mais específica sobre um comando: DBCC HELP(‘SQLPERF’)
Bom,,, agora vem a parte divertida,,,
Para exibir os não documentados você precisa habilitar um TRACEON: DBCC TRACEON(2588) — O 2588 é para 2005 e 2008, para 7 e 2000 é 2520
Depois de habilitar o traceon execute um: DBCC HELP(‘?’) WITH NO_INFOMSGS
Agora vem um esquema camarada legal,,,
Salve o resultado em um arquivo. Ex.: c:\dbcc.txt
Crie uma tabela temporária e importe os registros do dbcc.txt
| IF OBJECT_ID(‘tempdb.dbo.#dbccs’) IS NOT NULL DROP TABLE #dbccs; GO CREATE TABLE #dbccs ( [dbcc] nvarchar(4000) NOT NULL ); GO DECLARE @bulkcmd varchar(8000) SET @bulkcmd = ‘BULK INSERT #dbccs FROM N”C:\dbcc.txt” WITH ( ROWTERMINATOR = ”’ + NCHAR(10) + NCHAR(13) + NCHAR(10) + ”’, DATAFILETYPE = ”widechar” )’; EXEC(@bulkcmd);– Execute o select abaixo e depois remova a tabela temporária SELECT ‘DBCC HELP(”’ + [dbcc] + ”’) WITH NO_INFOMSGS’ FROM #dbccs ORDER BY [dbcc]; DROP TABLE #dbccs |
Com o resultado do SELECT você terá algo como:
