Something I needed today... I wish this was standarized, but it is not, so here are some examples:
SQL Server:
SELECTTOP10product,descr,email
FROMproducts
FROMproducts
ORACLE:
SELECTproduct,descr,email
FROMproducts
WHEREROWNUM<=10
FROMproducts
WHEREROWNUM<=10
MySQL:
SELECTproduct,descr,email
FROMproducts
LIMIT10
FROMproducts
LIMIT10
