I am trying to execute a simple proc Like this in oracle 10g but not able to do getting error PLS-00905: object dbnew.sp_TDCCountry is invalid any idea would be appreciated
Table
CREATE TABLE TDCCountry
( CountryID number(10) NOT NULL,
CountryName varchar2(50) NOT NULL
);
Procedure
CREATE OR REPLACE PROCEDURE SP_TDCCountry
IS
BEGIN
select * from tdcCountry;
COMMIT;
END SP_TDCCountry;
Execution
1.
begin
SP_TDCCountry;
end;
2.exec SP_TDCCountry;
Because you do not have an into clause by which you return values to some variables. It may be proper to return your variable as a rowtype [ By the way a commit is not needed for a non-DDL( in this case, there's a SELECT) statement ].
So, You may use in the following way :
SQL> set serveroutput on;
SQL> CREATE OR REPLACE PROCEDURE SP_TDCCountry IS
v_row tdcCountry%rowtype;
BEGIN
select * into v_row from tdcCountry;
dbms_output.put(v_row.countryid||' - ');
dbms_output.put_line(v_row.countryname);
END;
/
SQL> exec SP_TDCCountry;
If your SELECT statement brings more than one row, then it's proper to return data by means of cursor :
SQL> CREATE OR REPLACE PROCEDURE SP_TDCCountry IS
v_row tdcCountry%rowtype;
BEGIN
for c in ( select * from tdcCountry )
loop
dbms_output.put(c.countryid||' - ');
dbms_output.put_line(c.countryname);
end loop;
END;
/
SQL> exec SP_TDCCountry;

Below sql command is not working in procedure
PROCEDURE P_EMPDETAIL
AS
V_WHERE := 'E.EMP_ID = 123'B
BEGIN
EXECUTE IMMEDIATE 'INSERT INTO EMPLOYEE E ' || V_WHERE || ;
END;
It seems to me there are various issues with your syntax and approach (you shouldn't be using dynamic SQL this way), perhaps you should learn PL/SQL and reference the manuals. The insert statement is also wrong. Below is the correct syntax.
CREATE OR REPLACE PROCEDURE P_EMPDETAIL as
V_WHERE varchar2(100);
BEGIN
V_WHERE := 'E.EMP_ID = 123';
EXECUTE IMMEDIATE 'INSERT INTO EMPLOYEE E (colname) values (1) ' || V_WHERE;
END;
Well, not exactly like that (obviously; otherwise, you wouldn't be asking for help).
It is unclear what you want to do because syntax is really strange. If you wanted to insert a row into the table, then:
SQL> CREATE TABLE employees
2 (
3 emp_id NUMBER
4 );
Table created.
SQL> CREATE OR REPLACE PROCEDURE p_empdetail (par_emp_id IN NUMBER)
2 AS
3 l_str VARCHAR2 (200);
4 BEGIN
5 l_str := 'insert into employees (emp_id) values (:1)';
6
7 EXECUTE IMMEDIATE l_str
8 USING par_emp_id;
9 END;
10 /
Procedure created.
Testing:
SQL> EXEC p_empdetail(123);
PL/SQL procedure successfully completed.
SQL> SELECT * FROM employees;
EMP_ID
----------
123

I need to write an oracle procedure which will have an array of ID's as parameter.
Then I will return a cursor which contains result of select(1).
(1) - select * from table where id in(ID's)
As an option we can pass a string param and then convert string to array.
DECLARE
info sys_refcursor ;
error varchar(255);
BEGIN
package.test_function('1,2,3',info ,error);// info will contain a result cursor for select(1)
END;
Do you have other ideas?
You can create a user-defined collection type:
CREATE TYPE int8_list IS TABLE OF NUMBER(8,0);
Then your package:
CREATE PACKAGE pkg_name AS
PROCEDURE proc_name (
i_ids IN int8_list,
o_cursor OUT SYS_REFCURSOR
);
END;
/
CREATE PACKAGE BODY pkg_name AS
PROCEDURE proc_name (
i_ids IN int8_list,
o_cursor OUT SYS_REFCURSOR
)
IS
BEGIN
OPEN o_cursor FOR
SELECT * FROM table_name WHERE id MEMBER OF i_ids;
END;
END;
/
Then you can call the procedure:
DECLARE
v_info sys_refcursor ;
v_id TABLE_NAME.ID%TYPE;
v_value TABLE_NAME.VALUE%TYPE;
BEGIN
pkg_name.proc_name(int8_list(1,2,3), v_info);
LOOP
FETCH v_info INTO v_id, v_value;
EXIT WHEN v_info%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(v_id || ' ' || v_value);
END LOOP;
END;
/
Which, for the sample data:
CREATE TABLE table_name (id, value) AS
SELECT LEVEL, CHR(64+LEVEL) FROM DUAL CONNECT BY LEVEL <= 5;
Outputs:
1 A
2 B
3 C

Hi i'm working on this query in oracle and i need to provide many id to a procedure from a table. how can i provide each id from a table to my procedure. sory i'm kinda new at this im completely lost i dont know what to search.
here's
Procedure
PROCEDURE procedname(in_id in VARCHAR2)
select id from mytable
Here's what i tryed
execute procedname(select id from mytable);
but did no work
Is there a way to achive this?
Hope somone help me out with this
You can pass a collection of numbers. Here is an example on how to pass.
--sys.odcinumberlist is a collection which can hold numbers..
create procedure sp_test(i_id in sys.odcinumberlist)
as
l_cnt int;
begin
select count(*)
into l_cnt
from TABLE(i_id); /* the TABLE keyword is used to unfold the collection of numbers as rows..*/
dbms_output.put_line(l_cnt);
end;
/
--calling the stored procedure
begin
dbms_output.enable;
sp_test(sys.odcinumberlist(1,2,3,4,5,6)); /* here i am passing a list of numbers from 1 to 6*/
--the procedure will count the number of elements in the input collection which is 6
end;
/
You cannot directly use a SQL statement as an argument for a procedure or function. Since that needs an INTO clause in order to return the content of the SELECT statement. Your case suggests a CURSOR as needs to return all the records at a time. For this, a possible sample solution using SYS_REFCURSOR as an IN/OUT(or just OUT) type of parameter would be ;
SQL> CREATE TABLE mytable( id VARCHAR2(1) );
SQL> INSERT INTO mytable VALUES('A');
SQL> INSERT INTO mytable VALUES('B');
SQL> CREATE OR REPLACE PROCEDURE Convert_ID(p_myrecordset IN OUT SYS_REFCURSOR) AS
BEGIN
OPEN p_myrecordset FOR
SELECT id, ASCII( id )
FROM mytable
ORDER BY id;
END;
/
SQL> SET SERVEROUTPUT ON;
SQL> DECLARE
l_cursor SYS_REFCURSOR;
l_value1 mytable.id%TYPE;
l_value2 INT;
BEGIN
Convert_ID(p_myrecordset => l_cursor);
LOOP
FETCH l_cursor
INTO l_value1, l_value2;
EXIT WHEN l_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(l_value1 || ' - ' || l_value2 );
END LOOP;
CLOSE l_cursor;
END;
/
A - 65
B - 66
Demo
To take each id from some table and call sometable(id), a PL/SQL loop would be something like this:
begin
for r in (
select id from sometable
)
loop
procedname(r.id);
end loop;
end;
How to create a function to display all employees of one department?
I'd tried this code but it returns only "cursor" value.
CREATE OR REPLACE FUNCTION emp_dept (dept_id IN NUMBER)
RETURN SYS_REFCURSOR
IS
emp_name SYS_REFCURSOR;
BEGIN
OPEN emp_name
FOR SELECT last_name
FROM employees
WHERE department_id = dept_id;
RETURN emp_name;
END emp_dept;
You may use these options to read and display output from the cursor that's returned from your function.
Use a simple select
select emp_dept(10) from dual;
Result
EMP_DEPT(10)
--------------------
CURSOR STATEMENT : 1
CURSOR STATEMENT : 1
LAST_NAME
-------------------------
Whalen
Use DBMS_SQL.RETURN_RESULT ( Oracle 12c and above)
DECLARE
l_cur SYS_REFCURSOR := emp_dept(10) ;
BEGIN
DBMS_SQL.RETURN_RESULt(l_cur);
END;
/
Result
PL/SQL procedure successfully completed.
ResultSet #1
LAST_NAME
-------------------------
Whalen
FETCH from the cursor into a local collection. A slight variation could be also be used to fetch into a scalar variable.
DECLARE
l_cur SYS_REFCURSOR := emp_dept(10) ;
TYPE l_last_name_tab IS TABLE OF employees.last_name%TYPE;
l_lnt l_last_name_tab;
BEGIN
FETCH l_cur BULK COLLECT INTO l_lnt;
for i in 1..l_lnt.count
loop
dbms_output.put_line(l_lnt(i));
end loop;
END;
/
Result
Whalen
PL/SQL procedure successfully completed.
Is it possible, if yes, what would the syntax look like for a stored proc which would pick a stored procedure from a list in a table and then executes it in an oracle db?
The stored procedure should use EXECUTE IMMEDIATE to execute an anonymous PL/SQL block with the procedure name. This can be as simple as creating a string like begin proc_name; end;. Things get more difficult if there are parameters and return values.
create table proc_table(id number, procedure_name varchar2(100));
insert into proc_table values(1, 'proc1');
insert into proc_table values(2, 'proc2');
create or replace procedure proc1 is begin dbms_output.put_line('1'); end;
/
create or replace procedure proc2 is begin dbms_output.put_line('2'); end;
/
begin
for procedures in
(
select procedure_name
from proc_table
order by procedure_name
) loop
execute immediate 'begin '||procedures.procedure_name||'; end;';
end loop;
end;
/
Output:
