CREATE PROCEDURE dbo.usp_ShrinkAllLogsExcludeSysDBS (@dbname SYSNAME = '%')

BEGIN

DECLARE @TSQLExec VARCHAR (MAX) = '';

SET NOCOUNT ON;

IF OBJECT_ID('tempdb..#Temp') IS NOT NULL

DROP TABLE #temp

CREATE TABLE #temp (dbname sysname, dbid int, logFileSizeBeforeMB decimal(15,2), logFileSizeAfterMB decimal(15,2));

WITH fs

(

SELECT database_id, TYPE, SIZE * 8.0 / 1024 SIZE

FROM sys.master_files

)

INSERT INTO #temp (dbname, dbid, logFileSizeBeforeMB)

SELECT

name, database_id,

(SELECT SUM(SIZE) FROM fs WHERE TYPE = 1 AND fs.database_id = db.database_id) LogFileSizeMB

FROM sys.databases db

WHERE database_id > 4

AND NAME LIKE @dbname;

SELECT @TSQLExec = CONCAT (

@TSQLExec,

'USE [',

d.NAME,

']; CHECKPOINT; DBCC SHRINKFILE ([',

f.NAME + ']) with no_infomsgs;' ,

Char (13),Char (10))

FROM sys.databases d,

sys.master_files f

WHERE d.database_id = f.database_id

AND d.database_id > 4

AND f.type = 1

AND d.NAME LIKE @dbname;

PRINT @TSQLExec;

EXEC (@TSQLExec);

WITH fs

(

SELECT database_id, TYPE, SIZE * 8.0 / 1024 SIZE

FROM sys.master_files

)

UPDATE a

set a.logFileSizeAfterMB = (SELECT SUM(SIZE) FROM fs WHERE TYPE = 1 AND fs.database_id = db.database_id)

FROM #temp a

inner join sys.databases db on a.dbid = db.database_id

WHERE database_id > 4

AND NAME LIKE @dbname

SELECT * FROM #temp ORDER BY dbname

SET NOCOUNT OFF;

END;

Depois rodamos o comando abaixo ou podemos também colocar em um Job.

USE master
GO
EXEC dbo.usp_ShrinkAllLogsExcludeSysDBS 
GO

USE master

EXEC dbo.usp_ShrinkAllLogsExcludeSysDBS
