In this article, I will try to give information about the physical dimensions of Tables in SQL Server.

In SQL Server, in some cases, you may want to learn the physical size information of the tables.

You can easily do this by using the query below.

SELECT t.name AS TableName,
       s.name AS SchemaName,
       p.rows AS RowCounts,
       SUM(a.total_pages) * 8 AS TotalSpaceKB,
       SUM(a.used_pages) * 8 AS UsedSpaceKB,
       (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM sys.tables t
    INNER JOIN sys.indexes i
        ON t.object_id = i.object_id
    INNER JOIN sys.partitions p
        ON i.object_id = p.object_id
           AND i.index_id = p.index_id
    INNER JOIN sys.allocation_units a
        ON p.partition_id = a.container_id
    LEFT OUTER JOIN sys.schemas s
        ON t.schema_id = s.schema_id
WHERE t.name NOT LIKE 'dt%'
      AND t.is_ms_shipped = 0
      AND i.object_id > 255
GROUP BY t.name,
         s.name,
         p.rows
ORDER BY t.name;

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

As can be seen, we have seen the physical dimension information of the tables.

Good luck to everyone in business and life.

In this article, I will talk about how to list updated tables in SQL Server.

In SQL Server, in some cases, it may be desirable to know which tables have been updated.

I will describe my transactions using the Northwind database.

Let’s check if there is a change on the related database using the following query.

SELECT tbl.name,
       ius.last_user_update,
       ius.user_updates,
       ius.last_user_seek,
       ius.last_user_scan,
       ius.last_user_lookup,
       ius.user_seeks,
       ius.user_scans,
       ius.user_lookups
FROM sys.dm_db_index_usage_stats ius
    INNER JOIN sys.tables tbl
        ON (tbl.object_id = ius.object_id)
WHERE ius.database_id = DB_ID();

When we call the query before making changes to any table, you will get a result like the one below.

As you can see, it came up empty because we didn’t make any changes (Insert, Update, Delete) in the database before.

Now, let’s make the CategoryName name Deniz Ürünleri for the category with CategoryID=8 in the Categories table.

UPDATE dbo.Categories
SET CategoryName = 'Deniz Ürünleri'
WHERE CategoryID = 8;

Let’s run the query.

As you can see we have updated it. Now let’s check with the first query we wrote.

As you can see, it showed us that there was an update in the Categories table.

Good luck to everyone in business and life.
