#Solution-1: SQL Query

The query joins information from the system catalog views such as “sys.tables”, “sys.indexes”, ”sys.partitions”, and “sys.allocation_units” to calculate the size of each table in KB(kilobytes) and as well as MB(megabytes).

It provides a detailed overview of all tables in the specified database, including the table name row count, total size, used size, and unused side. The results are ordered by total size in descending order, so you can easily identify the largest tables.

SELECT 
    t.name AS TableName,
    s.name AS SchemaName,
    p.rows,
    SUM(a.total_pages) * 8 AS TotalSpaceInKB, 
    CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceInMB,
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceInMB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceInKB,
    CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceInMB
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 
    TotalSpaceInMB DESC, t.name;

#Solution-4: To Get the size of all tables in the SQL Server Database

In SQL Server, it is an easier way to get the size of all tables in the database is to use the Standard Report feature available in SQL Server Management Studio.

• Open the SSMS (SQL Server Management Studio)
• Now, Right Click on the Selected Database.
• Select Reports
• Next, Select Standard Reports
• Then Click on Disk Usage by Table

Here’s a Query to find all identity columns in a database.

Using SQL Server to Find All Identity Columns in the Database

SELECT 
	OBJECT_SCHEMA_NAME(tables.object_id, db_id())
	AS SchemaName,
	tables.name As TableName,
	columns.name as ColumnName
FROM sys.tables tables 
	JOIN sys.columns columns 
ON tables.object_id=columns.object_id
WHERE columns.is_identity=1

This query retrieves the table and column names of identity columns in a Database.

Another way to find all identity columns in the Database. It contains details of all identity columns in a database along with their seed value, increment value, and other information. The below query for the same is given.

SELECT 
	OBJECT_SCHEMA_NAME(tables.object_id, db_id())
	AS SchemaName,
	tables.name As TableName,
	identity_columns.name as ColumnName,
	identity_columns.seed_value,
	identity_columns.increment_value,
	identity_columns.last_value
FROM sys.tables tables 
	JOIN sys.identity_columns identity_columns 
ON tables.object_id=identity_columns.object_id

An effective tool for administering SQL Server databases is called SQL Server Management Studio (SSMS). Users can communicate with SQL Server via its graphical user interface (GUI) without having to write any code. However, navigating SSMS with the mouse can be cumbersome and ineffective. Tasks can be completed more quickly and conveniently by using keyboard shortcuts.

 SQL Server Management Studio (SSMS) – what is it?

Users can administer SQL Server databases using the free Microsoft application SQL Server Management Studio (SSMS). For activities like building databases, tables, and stored procedures as well as running queries and managing users, it offers a user-friendly interface.

Why should you utilize keyboard shortcuts?

Keyboard shortcuts enable users to complete activities quickly and efficiently by avoiding the need to travel through menus and options. This saves time and effort, which is especially beneficial for recurring jobs. Keyboard shortcuts also lessen the possibility of errors by requiring less mouse movement and clicking.
