Create table statement in Dynamic SQL

Question

Hello,
I am trying to create a table as a select query through a PL/SQL block using dynamic SQL. Following is the query,
declare
stmt varchar2(2000);
begin
stmt := '''CREATE TABLE output AS SELECT PATIENT_ID, FIRST_NAME FROM employee''';
execute immediate stmt;
end;
it throws the following error.
declare
ERROR at line 1:
ORA-00900: invalid SQL statement
ORA-06512: at line 5
I have tried to execute the statement without the variable and it executes fine. I mean,
begin
execute immediate ' CREATE TABLE output AS SELECT PATIENT_ID, FIRST_NAME FROM employee ';
end;
works flawlessly. Can you please help me with this.
Thanks

Hi,
declare
stmt varchar2(2000);
begin
stmt := 'CREATE TABLE output AS SELECT PATIENT_ID, FIRST_NAME FROM employee';
execute immediate stmt;
end;Nothing different from what Anurag has shown above.
But you will have to consider a few things.
1) Since it is possible it is not a must to use it
2) It is considered a bad design where in you have to create tables on the fly.
3) Consider if it is absolutely required.If u can give us an idea of your requirement.I am sure the Gurus here can give you suggestions
4) this kind of design will lead you into trouble sooner or later for sure
