Hi

I know there'd be a reason, but I can't understand that..

mysql> select @valore:=rand(), @valore, @valore:="ciao", @valore;
+-------------------+-------------------+-----------------+---------+
| @valore:=rand() | @valore | @valore:="ciao" | @valore |
+-------------------+-------------------+-----------------+---------+
| 0.483624490428366 | 0.483624490428366 | ciao | 0 |
+-------------------+-------------------+-----------------+---------+
1 row in set (0.00 sec)

mysql> select @valore:=rand(), @valore, @valore:="ciao", @valore;
+-------------------+-------------------+-----------------+---------+
| @valore:=rand() | @valore | @valore:="ciao" | @valore |
+-------------------+-------------------+-----------------+---------+
| 0.747058809499311 | 0.747058809499311 | ciao | ciao |
+-------------------+-------------------+-----------------+---------+
1 row in set (0.00 sec)

why in the first execution the latest value is 0 and not 'ciao'?
and why in the first 2 columns the variables seems works as expected!?

thank you in advance

bye
MAS!
