In SQL Server, there are commonly two ways to view table definition. The first method is by using SQL Server Management Studio, and the second way is by executing Transact-SQL queries. Let’s discuss both methods in more detail. To fetch the definition of a table, we need to follow the following steps in SQL Server Management Studio.
From the list of tables, right-click the required table and click on Design option. This will open a table designer page where we can easily view the table structure as well as its properties. Alternatively, there are multiple options in SQL Server, using which we can fetch table structure details.
Displaying table contentsright-click and select Display.click on the Table > Display Table menu option.hit F9.right click and select View > Contents (first 30 rows). This will display a sample of the table (the first 30 rows) in the right-hand grid.

An aggregate function performs a calculation on a set of values, and returns a single value. Except for COUNT(*) , aggregate functions ignore null values. Aggregate functions are often used with the GROUP BY clause of the SELECT statement.
First, you need to write a CTE in which you assign a number to each row within each group. To do that, you can use the ROW_NUMBER() function. In OVER() , you specify the groups into which the rows should be divided ( PARTITION BY ) and the order in which the numbers should be assigned to the rows ( ORDER BY ).
Selecting a top n records for each category from any table, can be done easily using row_number function which generates a sequential integer to each row within a partition of a result set.
On the Design tab, in the Query Setup group, click the down arrow next to Return (the Top Values list), and either enter the number or percentage of records that you want to see, or select an option from the list.
The SQL MAX function is used to return the maximum value of an expression in a SELECT statement.
SQL MIN() and MAX() FunctionsSELECT MIN(column_name) FROM table_name. WHERE condition;SELECT MAX(column_name) FROM table_name. WHERE condition;Example. SELECT MIN(Price) AS SmallestPrice. FROM Products;Example. SELECT MAX(Price) AS LargestPrice. FROM Products;
SELECT MAX (column_name) FROM table_name WHERE column_name NOT IN (SELECT Max (column_name) FROM table_name); First we selected the max from that column in the table then we searched for the max value again in that column with excluding the max value which has already been found, so it results in the 2nd maximum value.
In this SQL Server example, we show you how to Select Top 2 rows in each Group using a subquery.
The ROW_NUMBER Function allows you to assign the rank number to each record present in a partition. You can also use remaining Ranking functions, as per your requirements.
Write a query to display the name (s) of the students who have secured the maximum marks in each subject, ordered by subject name in ascending order. If there are multiple toppers, display their names in alphabetical order.

In SQL Server, we can easily view a table using a SELECT statement. And the main usage of the SELECT statement is to fetch data from database objects. However, a table in one just database object whose data can be fetched using SELECT statement.
In this section, we will illustrate how to view the definition of a table in SQL Server. Now, a table in SQL Server is also a database object that holds data stored in a database. Moreover, tables are similar to spreadsheets in that data is logically structured in a row-and-column manner.
In SQL Server, multiple tables are linked together using primary and foreign keys. And this link between tables can be stated as a relationship between them. However, to view the relationship between tables, we need to view the foreign key attributes.
In SQL Server, a schema is a set of the logical structure of data. And tables, views, triggers, stored procedures, indexes, and other database objects are all part of a schema. Moreover, the owner of these logically related database objects is associated with a username known as the schema owner.
In SQL Server, we can easily view the structure of a table either using SQL Server Management Studio or by executing a query. Therefore, we will illustrate both methods with an example.
In this section, we will understand how to view the data of a table in SQL Server Management Studio. Now, to implement this task, we can follow the following steps in SQL Server Management Studio.
SQL Server also facilitates the use of inserted and deleted tables. These tables are mainly utilized in DML trigger statements to define conditions for trigger actions and to test the impacts of various data changes. Moreover, these temporary tables are created and managed automatically by SQL Server.
Listing all the tables in SQL server when using a newer version (SQL 2005 or greater) is a matter of querying the INFORMATION_SCHEMA views which are automatically built into SQL Server. These allow you to easily view a wide variety of metadata for this particular SQL Server instance, including information about COLUMNS, ROUTINES, and even TABLES.
You may notice that there are four columns returned when using the INFORMATION_SCHEMA.TABLES view, but the most important column is TABLE_TYPE, which determines whether the table in that row is an actual table ( BASE TABLE) or a view ( VIEW ).
