I want to create stored procedure which will give output rows from "values that are passed as one parameter (comma seperated) to store procedure".

Hello,
I want to create stored procedure which will give output rows from "values that are passed as one parameter (comma seperated) to store procedure".
Suppose ,
Parameter value : person 1,person2,person3
table structure :
Project Name | officers 1 | officers 2
here, officers 1 or officers 2 may contain names of multiple people.
expected OUTPUT : distinct list(rows) of projects where person 1 or person 2 or person 3 is either officer1 or officer 2.
please explain or provide solution in detail
- Thanks

Hi Visakh,
Thanks for reply.
But the solution you provided giving me right output only if officer 1 or officer 2 contains single value , not with comma seperated value.
Your solution is working fine for following scenario :
Project
Officers 1
Officers 2
p1
of11
off21
p2
of12
off22
with parameter : of11,off22 : it will give expected output
And its not working in case of :
Project
Officers 1
Officers 2
p1
of11,of12
off21,off23
p2
of12,of13
off22,off24
with parameter : of11,off22 : it will not give any row in output
I need patten matching not exact match :)
ok
if thats the case use this modified logic
CREATE PROC GetProjectDetails
@PersonList varchar(5000)
AS
SELECT p.*
FROM ProjectTable p
INNER JOIN dbo.ParseValues(@PersonList,',')f
ON ',' + p.[officers 1] + ',' LIKE '%,' + f.val + ',%'
OR ',' + p.[officers 2] + ',' LIKE '%,' + f.val + ',%'
GO
Keep in mind that what you've done is a wrong design approach
You should not be storing multiples values like this as comma separated list in a single column. Learn about normalization . This is in violation of 1st Normal Form

passing table name to a procedure while calling(fp_table_old captures this value) and then need to open a cursor for this table in 'for i in (select * from fp_table_old )', one of the ways I tried is : for i in (execute immediate Lv_sql_query ) but its not working for me, please find the code below for reference, I know I am sounding stupid but I have been very out of touch, please help.

Help passing table name as parameter to a procedure

Hello,
i'm trying to write a procedure that takes a table name as input and uses a cursor to select a column,count(1) from the passed table to the cursor. The procedure i've come up with is as follows,

That aside, what do you want to return? You're selecting a column and applying an aggregate function (count) but you're not grouping, that doesn't usually work out too well.
TUBBY_TUBBZ?select owner, count(*) from all_objects;
select owner, count(*) from all_objects
ERROR at line 1:
ORA-00937: not a single-group group functionWhy do you perceive the need to be able to take in ANY table name, can't you design an application where table names are known at compile time and not run time?

Passing Table Name to Stored Procedure for From Clause

Is it possible to pass a table name to a stored procedure to be used in the From clause? I have the same task to perform with numerous tables and I'd like to use the same SP and just pass the table name in. Something like this:
=======================================
CREATE OR REPLACE PROCEDURE SP_TEST(
in_TABLE IN VARCHAR2,
AS
V_TABLE VARCHAR2(10);
BEGIN
V_TABLE := 'st_' || in_TABLE; -- in_TABLE is 2-3 character string
SELECT some_columns
INTO some_variables
FROM V_TABLE
WHERE some_conditions...;
END;
=======================================
I'm also using the passed table name to assign to variables in the Select and Where clauses. What I'm getting is an error that V_TABLE must be declared. When I hard code the table name, I don't get any errors, even though I'm also using the same method to assign values in the Select and Where clauses.
Thanks,
Ed Holloman

You need to use dynamic SQL whenever you are swapping out object names (tables, columns).
create or replace procedure sp_test
(in_table in varchar2)
is
-- variables
begin
execute immediate 'select a, b, c from st_' || in_table || ' where x = :xval and y = :yval'
into v_a, v_b, v_c using v_x, v_y;
end;

How i will pass table within procedure

how i will pass table within procedure and call another procedure.
can anybody give some example

You are not specific at all. Do you mean you want to pass table_name as parameter to a procedure? Do you want to pass tables_name dynamically while the procedure is running? If so, use dynamic sql. You can directly call another procedure within a procedure.
create or replace procedure sample_proc
as
v_table_name varchar2(10);
begin
   select table_name into v_table_name
   from user_tables
   where table_name = 'EMP';
   procedure_2(v_table_name);
end;And the procedure_2 would be
create or replace procedure procedure_2(p_table_name varchar2)
as
begin
   execute immediate 'DROP TABLE '||p_table_name;
end;For God's sake please completely describe what you want, otherwise we don't know what on Earth you want!
Cheers

Create a procedure which requires displaying information from two tables

What if we want to create a procedure which requires displaying information from two tables. In this situation,
I need to display all the details of an employee from an 'emp' table based on the deptno. and also their salary information which is
stored in "Salgrade" Table. Is the use of "And" the correct way of using it?
Do I need to declare all the attributes before begin or I can just access them directly? Thanks
Create Procedure findDept
( I_deptno IN number
) As
Begin
Select Ename, Job, MGR, Hiredate, Sal, Comm, Dept_no from emp and exp, grade , location from salgrade where dept_no
= I_Deptno;
Exception
When NO_Data_Found then
DBMS_Output.Put_Line(' Department not found"|| I_deptno);
End findDept;

Hi,
Besides Qwerty's remark, you've also got a quoting error:
Change
DBMS_Output.Put_Line(' Department not found"|| I_deptno);
{code}
into
{code}
dbms_output.put_line(' Department not found: '|| i_deptno);
{code}
Which leads to the question:
What do you want to do when a record is found?
Display it?

Pass table name to procedure

hi
Can any one plz suggest me , how to pass
table name (that would be varchar) to a procedure,such that i
should be able to do DML and DDL on the table refered !!

EXECUTE IMMEDIATE executes the SQL statement held in a specified
VARCHAR2. So, with a bit of string concatenation, you can make
the statement dynamic, thus:
EXECUTE IMMEDIATE 'DELETE * FROM emp' ;
could become:
EXECUTE IMMEDIATE 'DELETE * FROM '||p_table_name ;
where p_table_name is a VARCHAR2 parameter passed into your
procedure. Check out the PL/SQL User's Guide and Reference,
chapter 10, for full details.

Passing TABLE NAME as parameter is possible or not?

I want develop a small/simple report like this
TABLE NAME :
WHERE :
ORDER BY :
QUERY ROWS
In the above model i want to pass all the three (TABLE NAME,WHERE and ORDER BY) as a parameter.
My doubt, is that possible to pass TABLE NAME as a parameter? If so!
When i enter any TABLE NAME it has to fetch me out the records of that table (Based on WHERE condition and ORDER BY).
Is that possible to do?
Need some help!
Edited by: Muthukumar Seshadri on Aug 10, 2012 6:19 PM

Yes, it is possible with lexical parameters. Look in the help for examples:
SELECT Clause
SELECT &P_ENAME NAME, &P_EMPNO ENO, &P_JOB ROLE FROM EMP
P_ENAME, P_EMPNO, and P_JOB can be used to change the columns selected at runtime. For example, you could enter DEPTNO as the value for P_EMPNO on the Runtime Parameter Form.
Note that in this case, you should use aliases for your columns. Otherwise, if you change the columns selected at runtime, the column names in the SELECT list will not match the Report Builder columns and the report will not run.
FROM Clause
SELECT ORDID, TOTAL FROM &ATABLE
ATABLE can be used to change the table from which columns are selected at runtime. For example, you could enter ORD for ATABLE at runtime.
If you dynamically change the table name in this way, you may also want to use lexical references for the SELECT clause (look at the previous example) in case the column names differ between tables.
WHERE Clause
SELECT ORDID, TOTAL FROM ORD WHERE &CUST
ORDER BY Clause
SELECT ORDID, SHIPDATE, ORDERDATE, TOTAL FROM ORD ORDER BY &SORT You have to be really careful with this approach. Dynamic SQL may cause serious performance problems.

Create a Procedure that will accept a variable

Hi,
I'm new to pl/sql and I'm trying to create a procedure that will accept a variable. I want to use this sql to create restore points that can store the name of each batch job as it runs.
The code works fine on it's own, but if I try to create the procedure it asks me for a value for 1, how do I stop it doing that?
CREATE OR REPLACE PROCEDURE create_restore_point AS
DECLARE
pointno number(5);
pointname varchar2(128) := upper('&1');
dbname v$database.name%TYPE;
scn_time date;
scn number;
BEGIN
SELECT restore_point_seq.nextval into pointno from dual;
SELECT name into dbname from v$database;
SELECT sysdate into scn_time from dual;
SELECT dbms_flashback.get_system_change_number into scn from dual;
INSERT into restore_point
values
(pointno,pointname,dbname,scn_time,scn);
commit;
END create_restore_point;
Many thanks in advance,
Tom.

It asks for value of 1 because you have &1 in your code. If you want to pass the value for pointname, then you can change your procedure like below.
CREATE OR REPLACE PROCEDURE create_restore_point (svar varchar2)AS
DECLARE
pointno number(5);
pointname varchar2(128) := upper(svar);
dbname v$database.name%TYPE;
scn_time date;
scn number;
BEGIN
SELECT restore_point_seq.nextval into pointno from dual;
SELECT name into dbname from v$database;
SELECT sysdate into scn_time from dual;
SELECT dbms_flashback.get_system_change_number into scn from dual;
INSERT into restore_point
values
(pointno,pointname,dbname,scn_time,scn);
commit;
END create_restore_point;

Passing table names through variables

Hi All,
Is it possible to pass the table name in a query using a variable.
For example - can we perform a select on a table where the table name is passed using a variable.
Pl assist. Thanks.

Hello,
Are you wanting to do this in a procedure? Say the table name being passed in as Input Parameter?
We can do that using Dynamic SQL:
CREATE PROCEDURE "PROC_01"
(IN v_IN_Var1 NVARCHAR)
LANGUAGE SQLSCRIPT AS
BEGIN
    DECLARE ABC NVARCHAR(300) := NULL;
    ABC := 'SELECT * FROM ' || :v_IN_Var1;
    EXEC (:ABC);
END;
CALL PROC_01 ('DUMMY');
But the only thing is you'll not be able to see the result set directly.
You might wan2 fire the select to insert the data into a different table.

How to write a procedure with the table name as an argument

I'm very new to Oracle, usually developing in SQL server.
I would like to write a procedure that accepts a table name and then does a
SELECT * FROM [table name] order by CollectionDate.
In SQL I would build up a varchar variable and then execute it.
Thanks

I often wonder why so many people new to Oracle want to do this as a first step, when most people who know what they are doing try and avoid it.

Pass table name as a parameter to function

Is there a way to pass table name as a parameter to functions? Then update the table in the function.
Thanks a lot.
Jiaxin

Hi, Harm,
Thank you very much for your suggestion and example. But to get my program work, i need to realise code like follows:
CREATE OR REPLACE FUNCTION delstu_func(stuno char) RETURN NUMBER AS
BEGIN
EXECUTE IMMEDIATE 'DELETE FROM student s' ||
'WHERE' || 's.student_number' || '=' || stuno;
LOOP
DBMS_OUTPUT.PUT_LINE('record deleted');
END LOOP;
END;
SELECT delstu_func('s11') FROM STUDENT;
The intention is to check if such a function can perform operations such as update, delete and insert on occurence of certain values. When executing the above statement, the system returns an error message:
ERROR at line 1:
ORA-00933: SQL command not properly ended
ORA-06512: at "SCMJD1.DELSTU_FUNC", line 3
Could you tell me where is wrong?
