Hello
I've used oracle for 10years,but I've never seen such notations.
In fact the SQL retuns an error .
<PostgreSQL>
postgres=# select E'\\';
?column?
----------
\
(1 row)
<ORACLE(10.2.0)>
SQL> select E'\\' from dual;
select E'\\' from dual
*
ERROR at line 1:
ORA-00923: FROM keyword not found where expected
--Of cource,this SQL works.
SQL> select '\\' from dual;
'\
--
\\
--or
SQL> set escape on
SQL> select '\\' from dual;
'
-
\
Sorry ,but I don't know SQLServer.
