If a dataset contains 50 rows, how to fetch rows between 10 and 20 only?
If you want sql query for above assuming your table name is mytable below query will work
select * from mytable order by id Offset 10 Rows fetch next 10 Rows only;
Assuming your dataset is in a table named my_table and has a column that can be used to order the rows (e.g. an auto-incrementing ID column named “id”), you can use the following SQL query to fetch rows 10 through 20:
SELECT *FROM my_tableORDER BY idLIMIT 10 OFFSET 9;
SELECT *
FROM my_table
ORDER BY id
LIMIT 10 OFFSET 9;
Explanation:
The specific way to fetch rows between 10 and 20 from a dataset depends on the programming language and technology being used. Here’s an example using C# and LINQ (Language Integrated Query):
var data = Enumerable.Range(1, 50).ToList(); // sample datasetvar result = (from item in data where item >= 10 && item <= 20 select item).ToList();
var data = Enumerable.Range(1, 50).ToList(); // sample dataset
var result = (from item in data
where item >= 10 && item <= 20
select item).ToList();
In this example, the data variable is a list of integers ranging from 1 to 50. The result variable contains a list of integers that are between 10 and 20 (inclusive). The where clause in the LINQ query filters the items in the data list that are greater than or equal to 10 and less than or equal to 20.
