On compilation the errors generated are:

Line # = 36 Column # = 17 Error Text = PL/SQL: ORA-00904:
"TOTALCOUNT": invalid identifier

Line # = 42 Column # = 17 Error Text = PL/SQL: ORA-00904:
"TOTALCOUNT": invalid identifier
1) My first doubt is why is the oracle db version of the stored
procedure not using "CREATE.." statement to create procedure.
2)why is the temporary table not being created in the oracle db
version of the procedure.
if i try to create a table using the following code,it gives errors
like :
CREATE TABLE tt_temp (
Summary VARCHAR2(30) ,
TotalCount NUMBER(10,0) );
Line # = 34 Column # = 4 Error Text = PLS-00103: Encountered the
symbol "CREATE" when expecting one of the following:
begin case declare end exception exit for goto if loop mod
null pragma raise return select update while with
<an identifier> <a double-quoted delimited-identifier>
<a bind variable> << close current delete fetch lock insert
open rollback savepoint set sql execute commit forall merge
pipe
3)why im getting this errors at all:
Line # = 35 Column # = 4 Error Text = PL/SQL: SQL Statement ignored
Line # = 36 Column # = 17 Error Text = PL/SQL: ORA-00904:
"TOTALCOUNT": invalid identifier
Im new to pl/sql and have a task of urgently converting t-sql to pl/
sql code. Any help in this direction will be appreciated.

First of all, I'd like to remind you that Oracle is NOT SQL Server,
and PL/SQL is NOT T-SQL, they are conceptually and syntactically
different. As of your questions:
1. What's the tool you're using to view the procedure source code?
Looks like a feature of your tool, as if they simply skip the obvious
"CREATE OR REPLACE PROCEDURE proc_name" line and add it under the hood
when you compile the procedure to form complete CREATE PROCEDURE
statement.
2. CREATE TABLE is an SQL statement, not a PL/SQL statement. If you
try to run it in a PL/SQL BEGIN...END; block, it will not execute and
syntax error will be reported - just like in your case. Looks like
your tool automatically and silently wraps PL/SQL statements into an
anonymous BEGIN...END; block.
3. Most probably that's because you already have TT_TEMP table with a
different definition and it doesn't have "TOTALCOUNT" column. Oracle
doesn't use the concept of dynamic local/global temporary tables so
common in SQL Server. In Oracle, all tables are permanent once you
create them (though content may be temporary if you create a GLOBAL
TEMPORARY table,) unlike SQL Server temporary tables which are
automatically dropped as soon as they go out of scope.
There are ways to simulate local temporary tables in Oracle, but
you'll need to familiarize yourself with quite a few Oracle concepts
by reading the documentation for your Oracle release. Start with
Oracle Concepts, Oracle PL/SQL Developer's Guide and Reference, SQL
Reference, and Application Developer's Guide - Fundamentals. All
Oracle documentation is available at http://tahiti.oracle.com
(requires free Oracle Technology Network registration.)
