How to limit the results on a SQL query

Question

I'm wondering is it possible to limit the result of a SQL request?

For example, only return up to 50 rows from:

  SELECT * FROM <table>

thanks.

Answer 1

Yes, this is possible. This differs between db engines.

Postgres:

SELECT * FROM <table> LIMIT 50

SQL Server:

SELECT TOP 50 * FROM <table>
