Temporary tables

Question

i am trying to create a temporary table in PL/SQL and want to insert rows.
create procedure temp
as
xsql varchar2(1000);
begin
vsql := 'create global temporary table t1 (n1 varchar2(50))';
execute immediate vsql;
insert into t1 values ('abc');
select * from t1;
end;
it does not allow me to compile and gives error ORA-00945: table or view does not exists

Answer 1

The following block might get created. As the table is created on the fly, (i.e is the table gets created and records inserted only when executing the procedure and not when the procedure is created), we cannot have the table name outside the variable.
Thanks,

create or replace procedure temp1
as
vsql varchar2(1000);
tbl_name varchar2(30) := 'T1';
v_ins varchar2(1000);
v_n1 varchar2(50);
v_sel varchar2(1000);
begin
vsql := 'create global temporary table t1 (n1 varchar2(50))';
execute immediate vsql;
v_ins := 'insert into'||tbl_name||'values (''abc'')';
execute immediate vsql;
v_sel := 'select n1 into v_n1 from t1';
execute immediate v_sel;
end;
