hi,

create user $1 identified by $2;
eof

but i dont want any file name to be passed,i just want to pass the parameter. is there any way to that??

i tried that &&;
sqlplus -s -l $dbausername/$dbapwd $1 $password <<eof
create user &&1 identified by &&2;
grant create session to &&1;
exit;
eof

sqlplus -s -l $dbausername/$dbapwd <<eof
create user $1 identified by $password;
grant create session to $1;
