SQL SELECT TOP N equivalent in ORACLE and MySQL

 

Something I needed today... I wish this was standarized, but it is not, so here are some examples:

SQL Server:

SELECT TOP 10 product, descr, email FROM products  

ORACLE:

SELECT product, descr, email FROM products WHERE ROWNUM <= 10  

MySQL:

SELECT product, descr, email FROM products LIMIT 10
