Request SQL

[Thierry Nauze]

Hello,

In broad outline, I have a table with two fields

FieldA 	FieldB
a		A
b 		A
c 		B
d 		A
e 		C
f 		B

Which request SQL (SELECT ...), if it is possible, it is necessary to 
use to obtain a cursor containing only the records where the 
occurrences of FielsB are multiple:
a		A
b 		A
c 		B
d 		A
f 		B

Thank you beforehand
