I am new to oracle, I am trying to grant the roles to the users via a procedure. I am receiving the following error. can someone please help me with this?
declare stmnt2 varchar(10000);
p_user_name varchar2(20);
v_role_name varchar2(20);
begin
v_role_name := 'ROLE';
p_user_name := 'TOM';
stmnt2 := 'grant '||v_role_name||' to '
||v_user_name||'; '
||' grant connect to '
||v_user_name ;
execute immediate stmnt2;
end;
/
Error report -
ORA-00900: invalid SQL statement
ORA-06512: at line 10
00900. 00000 - "invalid SQL statement"
Thank you
You don't have spaces in your statement:
stmnt2 := 'grant '||v_role_name||' to '||p_user_name;
This must work better.

I am trying to run the below script. My script works fine without ' WITH ADMIN OPTION' in EXECUTE IMMEDIATE. But when using ' WITH ADMIN OPTION' i get below error.
"Error report - ORA-00900: invalid SQL statement ORA-06512: at line 17

SET SERVEROUTPUT ON;

Try to add a space after grant keyword:
EXECUTE IMMEDIATE 'grant '||v_dba_role_privs||' to '||v_Cloned_UserName||' WITH ADMIN OPTION';
I have a table with columns insert,select,where clause,dynamic where clause,group by clause.
Using procedure i need to execute insert into statement and also use dynamic where clause.
I tried the following one however it is giving me an error missing expression.

THEN
dbms_output.put_line(processQuery);
EXECUTE IMMEDIATE processQuery USING Process_Date;
ELSE
EXECUTE IMMEDIATE processQuery;
END IF;
END LOOP;
CLOSE Process_Report;
END;
While executing the proc it is giving me the below error.

Your questions is not 100% clear . you saying after DATEE is being empty, are you assigning a variable after date ? the below is example of how using execute immediate with a variable. Note how is the bind variable :i is showing in the print.
set serveroutput on size 1000
/
declare t number(4) :=10;
txt varchar2(100);
begin
txt :='INSERT INTO TAB (ID) values (:i)';
dbms_output.put_line(t || ' ' || txt);
execute immediate txt using T;
end;
/
PL/SQL procedure successfully completed

I wrote this script to grant execute on functions on the source DB so that they are accessible from another DB using the DBlink. The scripts runs without issues, but I still cannot access the functions.
DECLARE
FNC_STRNG VARCHAR2(4000);
CURSOR CUR IS
SELECT * FROM USER_OBJECTS
WHERE OBJECT_TYPE = 'FUNCTION';
BEGIN
FOR I IN CUR LOOP
BEGIN
FNC_STRNG := 'GRANT EXECUTE ON schema_name.' || I.OBJECT_NAME || ' TO
DB_LNK';
EXECUTE IMMEDIATE FNC_STRNG;
EXCEPTION
WHEN OTHERS THEN
NULL;
END;
END LOOP;
END;
Once I run this script...
PL/SQL procedure successfully completed.
Then when I try to access the functions using this script:
SELECT schema_name.func_name#db_link(param1, param2) FROM schema_name.table_name#db_link;
And I get this error:
00904. 00000 - "%s: invalid identifier"
I have a PL/SQL script to perform some aggregation tasks. I am having compilation errors, logic is not top priority at this moment as that can be changed once the errors are resolved. The script is as follows :

Any help on where I am going wrong is highly appreciated?
PL/SQL is a framework for running SQL statements programmatically. So often we find that PL/SQL errors are caused by the SQL errors in our code.
That is the case here. You have several PL/SQL errors indicating that the Cursor declaration is invalid. And why is it invalid? This line holds the answer:
6/15 PL/SQL: ORA-00942: table or view does not exist
So the problem is, the owner of the procedure UPDATEFEATUREPERFORMANCETABLE (ugly name by the way) does not have rights on gfmdev.feature_performance.
To solve, the table owner GFMDEV needs to grant SELECT and INSERT directly to the account which owns this procedure.
SQL> conn gfmdev/password
SQL> grant select, insert on feature_performance to whoever;
Note that granting privileges through a view won't cut it. The Oracle security model only permits us to build objects - PL/SQL programs, views - with privileges granted directly to our user.
I am executing the following snippet of code
set serveroutput on;
DECLARE
TYPE emp_rec_type IS record (emp_id NUMBER,salary NUMBER);
emp_rec emp_rec_type;
l_out number;
l_statement varchar2(1000);
BEGIN
emp_rec.emp_id := 1;
emp_rec.salary := 1000;
SELECT emp_rec.salary INTO l_out FROM dual WHERE 1=1;
dbms_output.put_line(l_out);
l_statement := 'select emp_rec.salary from dual where 1=1';
execute immediate l_statement into l_out;
dbms_output.put_line(l_out);
END;
I am getting the below output
Error report:
ORA-00904: "EMP_REC"."SALARY": invalid identifier
ORA-06512: at line 23
00904. 00000 - "%s: invalid identifier"
*Cause:
*Action:
1000
I am expecting the output to be
1000
1000
Why is it that the dynamic statement execution insists on emp_rec.salary being an invalid identifer while the Select into statement works fine?
Is there something else I need to do to make it work?
The content of the EXECUTE IMMEDIATE statement is running in a completely different scope to the rest of your PL/SQL code - you can't reference PL/SQL variables directly.
If you want to use the contents of emp_rec.salary in the dynamic statement, you should bind in the value like so:
l_statement := 'SELECT :1 FROM dual WHERE 1=1';
EXECUTE IMMEDIATE l_statement INTO l_out USING emp_rec.salary;
