Hi,

I'm testing Oracle database 12.1.0.2.160531 on a french Windows 7

I've got some errors with the import script I'm using. Here a test case :

sqlplus system/passwd@127.0.0.1/server.local

create user toto identified by passwd;

create table toto.A (i integer);

create table toto.B (i integer);

exit

expdp system/passwd@127.0.0.1/server.local dumpfile=toto.dmp  schemas=toto

impdp system/passwd@127.0.0.1/server.local SCHEMAS=toto dumpfile='toto.dmp' logfile='toto.log' exclude=table:\"like 'B'\"

if I use the Release 11.2.0.4.0 impdp.exe, connected to the
