In this article, I will try to give information about learning the physical size of a table in SQL Server.

In SQL Server, in some cases you may want to know the physical size of a table.

We use the sp_spaceused procedure for this operation.

We run our procedure by saying exec.

EXEC sp_spaceused;

After that, parts such as name information, rows information, and data information of the Products table come.

Good luck to everyone in business and life.

In this article, I will try to give information about which database uses how much RAM in SQL Server.

In SQL Server, you may want to know how much RAM each database uses in some cases.

You can easily do this using the code below.

SELECT
	[DatabaseName] =
	CASE [database_id]
		WHEN 32767 THEN 'Kaynak DB'
		ELSE DB_NAME([database_id])
	END
   ,COUNT_BIG(*) [Pages in Buffer]
   ,COUNT_BIG(*) / 128 [Buffer Size in MB]
FROM sys.dm_os_buffer_descriptors
GROUP BY [database_id]
ORDER BY [Pages in Buffer] DESC;

In this article, I will try to give information about checking when the database was last backed up in SQL Server.

In SQL Server, in some cases, you may want to check when the database was last backed up.

You can easily do this using the code below.

;WITH CTE_Backup
AS (SELECT database_name,
           backup_start_date,
           type,
           physical_device_name,
           ROW_NUMBER() OVER (PARTITION BY database_name, BS.type ORDER BY backup_start_date DESC) AS RowNum
    FROM msdb..backupset BS
        JOIN msdb.dbo.backupmediafamily BMF
            ON BS.media_set_id = BMF.media_set_id)
SELECT D.name,
       ISNULL(CONVERT(VARCHAR, backup_start_date), 'No backups') AS last_backup_time,
       D.recovery_model_desc,
       state_desc,
       CASE
           WHEN type = 'D' THEN
               'Full database'
           WHEN type = 'I' THEN
               'Differential database'
           WHEN type = 'L' THEN
               'Log'
           WHEN type = 'F' THEN
               'File or filegroup'
           WHEN type = 'G' THEN
               'Differential file'
           WHEN type = 'P' THEN
               'Partial'
           WHEN type = 'Q' THEN
               'Differential partial'
           ELSE
               'Unknown'
       END AS backup_type,
       physical_device_name
FROM sys.databases D
    LEFT JOIN CTE_Backup CTE
        ON D.name = CTE.database_name
           AND RowNum = 1
ORDER BY D.name,
         type;

When you run the above code, you will see a result similar to the one below.

As you can see, we checked when the database was last backed up.

In this article, I will provide information about listing 365 days in SQL Server.

In SQL Server you may want to list 365 days in some cases.

You can easily do this using the code below.

WITH mycte AS
(
  SELECT CAST('2021-01-01' AS DATETIME) DateValue
  UNION ALL
  SELECT  DateValue + 1
  FROM    mycte   
  WHERE   DateValue + 1 <= '2021-12-31'
)

SELECT  DateValue
FROM    mycte
OPTION (MAXRECURSION 0)

When you run the above query, you will see a result similar to the one below.

As you can see, we have listed 365 days in SQL Server.

Good luck to everyone in business and life.
