How do I limit the number of rows returned by a query after ordering in PostgreSQL?

 To limit the number of rows returned by a query after ordering in PostgreSQL, you can use the "LIMIT" clause in your query. This clause specifies the number of rows that should be returned from the result set after sorting. Here's an example query:

vbnet
SELECT column1, column2, column3
FROM your_table
ORDER BY column1
LIMIT 10;

In this example, the query will return the first 10 rows of the result set after sorting by "column1". You can adjust the number of rows returned by changing the number after the "LIMIT" keyword.

Additionally, you can use the "OFFSET" keyword to skip a certain number of rows before returning the results. For example, to return rows 11-20 of the result set after sorting, you can use the following query:

sql
SELECT column1, column2, column3
FROM your_table
ORDER BY column1
LIMIT 10 OFFSET 10;

This query will skip the first 10 rows and return the next 10 rows after sorting by "column1".
