My code
CREATE OR REPLACE proc_grade IS
v varchar2(20);
c varchar2(20);
t integer(10);
x integer(10);
CURSOR s IS
SELECT total_marks,name,roll_no FROM STUD_MARKS ORDER BY roll_no;
BEGIN
OPEN s;
LOOP
FETCH s INTO x,c,t;
BEGIN
v:=grade(x);
INSERT INTO result VALUES(t,c,v);
dbms_output.put_line('ROLL_NO : '||t||'NAME: '||c||' CLASS: '||v);
END;
EXIT WHEN s%notfound;
END LOOP;
CLOSE s;
END;
Error that I am getting is as follows:
ORA-00922: missing or invalid option

CURSOR s IS
It is not
CREATE OR REPLACE proc_grade
but
CREATE OR REPLACE PROCEDURE proc_grade
By the way, you could have done it way simpler by running only this instead of all the PL/SQL you wrote.
INSERT INTO result
SELECT roll_no, name, grade (total_marks)
FROM stud_marks;

You can use FETCH:
declare
lang_cur SYS_REFCURSOR;
lang_name LANGUAGE_SELECT.LANG_NAME%TYPE;
begin
movie_pkg.lang_display(lang_cur);
LOOP
FETCH lang_cur INTO lang_name;
EXIT WHEN lang_cur%NOTFOUND;

I'm able to run an anonymous PL/SQL block and set an initial_rsrc_consumer_group via DBMS_RESOURCE_MANAGER in Oracle 19; however, when I attempt to name it as a stored procedure it throws ORA-00942: table or view does not exist.
Anonymous plsql block that runs ok:

What changed now that I've named the procedure?
I have this procedure:
create or replace
PROCEDURE P_P2
IS
v_str varchar2(1000);
v_file_name varchar2(1000);
BEGIN
P_P1(v_str, 'EXPORT_CSV',v_file_name);
v_str := 'select * from H----)';
v_file_name := 'H_'||to_char(sysdate,'DD-MM-YYYY')||'.csv';
END;
I am getting error "ORA-06561: given statement is not supported by package DBMS_SQL" when I execute it:
Error starting at line : 165 in command -
exec P_P1
Error report -
ORA-06561: given statement is not supported by package DBMS_SQL

06561. 00000 - "given statement is not supported by package DBMS_SQL"
*Cause: Attempting to parse an unsupported statement using procedure
PARSE provided by package DBMS_SQL.
*Action: Only statements which begin with SELECT, DELETE, INSERT, UPDATE,
LOCK, BEGIN, DECLARE or << (PL/SQL label delimiter) are supported.
I cannot see why. What am I doing wrong?
You haven't shown what P_P1 is doing, but from what you have shown, your P_P2 procedure may just be calling it too early; you have a call to P_P1 which uses v_str as a parameter, but it's null at that point - you set it after the call that uses it.
That means that somewhere in P_P1 you are probably ending up doing the equivalent of:
dbms_sql.parse(c, null, dbms_sql.native);
which throws the error you are seeing. You're doing the same with v_filename, which will presumably cause other issues.
So for a start, swap those lines around so the procedure is called last:
create or replace
PROCEDURE P_P2
IS
v_str varchar2(1000);
v_file_name varchar2(1000);
BEGIN
v_str := 'select * from H----)';
v_file_name := 'H_'||to_char(sysdate,'DD-MM-YYYY')||'.csv';
-- call this AFTER populating the variables
P_P1(v_str, 'EXPORT_CSV',v_file_name);
END;
/
You may have other problems of course - the table name looks odd, both because of the dashes and the closing parenthesis; but you may have just hidden the real name oddly. You seem to have changed the procedure names too (though inconsistently, as your exec seems to be calling the wrong one...).
I have created a procedure and it requires Dynamic SQL block.
Procedure is as below which complies correctly but when I try to run it , it gives the below error.
I have tried to use cast() for all the variable which are used here. But this does not help.
Also, I am trying to run this procedure on Oracle using SQL - Developer tool.
Once the dynamic SQL is stored in sqlquery variable I would try and run the dynamic query and display its results!

Using Oracle SQL Developer I created a simple procedure. The procedure compiles successfully, but when I type the command:

Please help me to solve this. I know it's a small error. Also I have specified the data types, declarations of names correctly.
My procedure code is
CREATE OR REPLACE PROCEDURE CMPPROJECTPROCSELECT(
p_projectname IN VARCHAR2,
p_description OUT VARCHAR2)
IS
BEGIN
SELECT DESCRIPTION
INTO p_description
FROM CMPPROJECT
WHERE PROJECTNAME = p_projectname;
EXCEPTION
WHEN NO_DATA_FOUND THEN
p_description:= NULL;
COMMIT;
END CMPPROJECTPROCSELECT;
execute CMPPROJECTPROCSELECT();
BEGIN CMPPROJECTPROCSELECT();
END;
EXECUTE is SQL*Plus command.
You are not passing the required parameters to the procedure. You have declared two parameters for your procedure:
p_projectname IN VARCHAR2,
p_description OUT VARCHAR2
So, you need to declare the required parameters and then pass it to the procedure:
DECLARE
proj_desc VARCHAR2(2000);
BEGIN
CMPPROJECTPROCSELECT('project_name', proj_desc);
-- use the OUT value of proj_desc later
END;
/
On a side note, you do not need COMMIT at all. It is required to permanently commit a DML and has nothing to do with a SELECT ..INTO clause.
SELECT DESCRIPTION INTO p_description FROM CMPPROJECT WHERE PROJECTNAME = p_projectname;
EXCEPTION
WHEN NO_DATA_FOUND THEN
p_description:= NULL;
COMMIT; -- You don't need COMMIT at all
