SQL Select Top
The SELECT TOP statement in SQL shows the limited number of records or rows from the database table. The TOP clause in the statement specifies how many rows are returned. It shows the top N number of rows from the tables in the output. This clause is used when there are thousands of records stored in the database tables.
Let’s take a simple example: If a Student table has a large amount of data about students, the select TOP statement determines how much student data will be retrieved from the given table.
Example:
SELECT TOP number | percent column_Name1, column_Name2, ….., column_NameN FROM table_name WHERE [Condition] ;
In this syntax, the pattern is a sequence of characters that have to be searched in that column which is just specified after the WHERE clause.
Let’s take the following Employee table which helps you to analyze the LIKE operator with % sign:
Suppose, you want to show the first three Names and Color of Car from the above table. To do this, you have to type the following query in SQL:
SELECT TOP 3 Car_Name, Car_Color FROM Cars;
This query shows the following table:
We have a table called Student with three columns:
Suppose, you want to show the details of the first four students in the result from the above table. To do this, you have to type the following query in SQL:
SELECT TOP 4 * FROM Student;
This query shows the following table:
We have a table called Employee with four columns:
Suppose, you want to show the details of those first four employees whose city is Goa from the above table. To do this, you have to type the following query in SQL:
SELECT TOP 4 * FROM Employee WHERE Emp_City = Goa ;
This query shows the following table:
