Rebuild All Indexes Script for SQL Server 2005 and Later

 Rebuild All Indexes Script for SQL Server 2005 and Later

The below script will work with SQL Server 2005 and later versions.

Because we need to change from database to database we need to create dynamic SQL code for the queries. The code uses master.sys.databases to get a list of databases as well as check the status for the database to make sure we are working with databases that are online.  This also uses INFORMATION_SCHEMA.TABLES to get a list of user tables in the database.

--Query Begins

DECLARE @Database NVARCHAR(255)   
DECLARE @Table NVARCHAR(255)  
DECLARE @cmd NVARCHAR(1000)  

DECLARE DatabaseCursor CURSOR READ_ONLY FOR  
SELECT name FROM master.sys.databases   
WHERE name NOT IN ('master','msdb','tempdb','model','distribution')  -- databases to exclude
--WHERE name IN ('DB1', 'DB2') -- use this to select specific databases and comment out line above
AND state = 0 -- database is online
AND is_in_standby = 0 -- database is not read only for log shipping
ORDER BY 1  

OPEN DatabaseCursor  

FETCH NEXT FROM DatabaseCursor INTO @Database  
WHILE @@FETCH_STATUS = 0  
BEGIN  

   SET @cmd = 'DECLARE TableCursor CURSOR READ_ONLY FOR SELECT ''['' + table_catalog + ''].['' + table_schema + ''].['' +  
   table_name + '']'' as tableName FROM [' + @Database + '].INFORMATION_SCHEMA.TABLES WHERE table_type = ''BASE TABLE'''   

   -- create table cursor  
   EXEC (@cmd)  
   OPEN TableCursor   

   FETCH NEXT FROM TableCursor INTO @Table   
   WHILE @@FETCH_STATUS = 0   
   BEGIN
      BEGIN TRY   
         SET @cmd = 'ALTER INDEX ALL ON ' + @Table + ' REBUILD' 
         PRINT @cmd -- uncomment if you want to see commands
         EXEC (@cmd) 
      END TRY
      BEGIN CATCH
         PRINT '---'
         PRINT @cmd
         PRINT ERROR_MESSAGE() 
         PRINT '---'
      END CATCH

      FETCH NEXT FROM TableCursor INTO @Table   
   END   

   CLOSE TableCursor   
   DEALLOCATE TableCursor  

   FETCH NEXT FROM DatabaseCursor INTO @Database  
END  
CLOSE DatabaseCursor   
DEALLOCATE DatabaseCursor

--Query Ends

I have excluded the system databases, so you can include these or add other databases to exclude from you index maintenance routines.  Also, you can change the code to include only specific databases instead.
