Is it possible to pass table name as parameter to function calls?

Let's say I would like to retrieve data from table BSAD, BSID, BSIS, BSAS with the exact same WHERE conditions.
I.E.
      SELECT SINGLE * FROM bsis
           WHERE bukrs = zbukrs
             AND belnr = zbelnr
             AND gjahr = zgjahr
             AND buzei = bseg-buzei.
      SELECT SINGLE * FROM bsas
           WHERE bukrs = zbukrs
             AND belnr = zbelnr
             AND gjahr = zgjahr
             AND buzei = bseg-buzei.
Is there a way that I could put them into a function and do something like?
perform select_table_bsas using 'bsas'.
perform select_table_bsis using 'bsis'.
and I should get SELECT * FROM passed from the function calls.
Thanks.

Hello,
You can try something like this
DATA : LV_DBTAB1 LIKE DD02L-TABNAME.
DATA : DREF TYPE REF TO DATA.
FIELD-SYMBOLS: <ITAB> TYPE ANY TABLE. " used to store dynamic tables
LV_DBTAB1 = 'MARA'. " in caps
CREATE DATA DREF TYPE STANDARD TABLE OF (LV_DBTAB1)
WITH NON-UNIQUE DEFAULT KEY.
ASSIGN DREF->* TO <ITAB> .
* chooses only english values
SELECT * FROM (LV_DBTAB1) INTO TABLE <ITAB> WHERE SPRAS = 'E'.
here, even the internal table is dynamic, but that can be static if you know the structure for sure

Not able to pass table name as parameter in function

Hi,
i am not able to pass tablename as parameter. I am using below function.
function count_test(tabname varchar2) return number is
l_count number;
begin
select count(*) INTO l_count FROM tabname;
RETURN l_count;
END;

You can't do it with static SQL.
The only way is to do it with dynamic SQL:
EXECUTE IMMEDIATE 'select count(*) FROM '|| tabname INTO l_count;

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.

Pass table name as parameter in prepared Statement

Can I pass table name as parameter in prepared Statement
for example
select * from ? where name =?
when i use setString method for passing parameters this method append single colon before and after of this parameter but table name should be send with out colon as SQL Spec.
I have another way to make sql query in programing but i have a case where i have limitation of that thing so please tell me is it possible with prepared Statment SetXXx methods or not ?
Thanks

Dynamic SQL : passing table name as parameter

Hi
I have a SQL query (a store procedure ) that i want to convert to PLSQL
This is a part of my SQL query that i am trying to to find a solution for it, because i cant convert it to oracle :
DECLARE lookupTableRow CURSOR FOR
SELECT TableName FROM SYS_LookUpTable
OPEN lookupTableRow
FETCH NEXT FROM lookupTableRow INTO @tableName
WHILE @@FETCH_STATUS=0
BEGIN
SET @sql='SELECT * FROM '+@tableName
EXECUTE sp_executesql @sql
IF @counter=0
BEGIN
INSERT INTO T_TABLE_MAPPING VALUES('P_MAIN_METADATA', 'Table', @tableName)
END
ELSE
BEGIN
INSERT INTO T_TABLE_MAPPING VALUES('P_MAIN_METADATA', 'Table'+CONVERT(NVARCHAR(10),@counter), @tableName)
END
SET @counter=@counter+1
FETCH NEXT FROM lookupTableRow INTO @tableName
END
CLOSE lookupTableRow
DEALLOCATE lookupTableRow
As i understand i can't use ORACLE dynamic sql (execute immediate) when the table name is a parameter
Furthermore when i execute this dynamic query in my SQL store procedure each SELECT statement return me as a result the relevant table rows , those result are different in each loop .
So i cant do this too with ORACLE dynamic sql .
Please advice for any solution
* how can i use dynamic sql with table name as parameter ?
* how can i use a "dynamic" cursor, in order to be able to display the dynamic results ?
Thanks for the advice

I have a SQL query (a store procedure ) that i want to convert to PLSQL
I doesn't help when you use one term to mean another thing.
SQL is a language used in both Oracle and other products, such as Microsoft's SQL Server. I don't know much about SQL Server, but Oracle (at least) doesn't support stored procedures in SQL itself; they have to be coded in some other language, such as PL/SQL.
As i understand i can't use ORACLE dynamic sql (execute immediate) when the table name is a parameter
If the table name is a parameter (or only known at run-time for any reason), that's exactly the kind of situation where you MUST use dynamic SQL.
The number of columns that a query produces (and their datatypes) is fixed when you compile a query, whether that query is dynamic or not. If you have multiple queries, that produce result sets with different numbers of columns, then you can't combine them into a single query. The best you can do with one query is to add NULL columns to some of the queries so they all produce the same number of columns.
If you're just displaying the results, there might not be any reason to combine separate result sets. Just display one result set after another.
Whenever you have a question, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Passing Table name as parameter to proc.

Hi,
I need to know how to pass a table name to a oracle procedure.
In that procedure I will put that table name in a variable and then I will make operations on that table like DELETE, UPDATE and INSERT.
Kinldy give me the solution for the above problem as soon as possible..

You shouldn't do it, but if you do, you can use something like this:

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?

Table name as parameter to function

Hi all,
can anybody help me on the below issue..
i have a function like this:
**create or replace**
**function "IL_SUM_AVG_FN" return number is**
**cursor c1 is**
**     select     sum_avg_val value**
**     from     wel_10_tab**
**     where     type='1';**
**v_sum number;**
**v_count number;**
**BEGIN**
**     v_sum:=0;**
**     v_count:=0;**
**     for i in c1 loop**
**          if v_count=0 then**
**               v_sum:=i.value;**
**          else**
**               v_sum:=abs(i.value+v_sum);**
**          end if;**
**          v_count:=v_count+1;**
**     end loop;**
**     return v_sum;**
**END;**
now my requirement is like..i want to pass a value as parameter to the function..say i will pass 10 or11 or 12
then it should change the table name in the cursor according to the parameter.i.e
if the parameter is 10 it should be: select sum_avg_val value from wel_10_tab where type='1';
if the parameter is 11 it should be: select sum_avg_val value from wel_11_tab where type='1';
if the parameter is 12 it should be: select sum_avg_val value from wel_12_tab where type='1';
parameter has only these three possible values..
how to achieve this?
please help..

Hi,
you can do without execute immediate and one cursor is sufficient, if you use open cursor for ...:
set serveroutput on;
drop table TestTab1;
drop table TestTab2;
create table TestTab1 (
     val number
create table TestTab2 as (select * from TestTab1 where 0 = 1);
create or replace procedure TestProc (
     TableName in varchar2)
is
     rec TestTab1%rowtype;
     cur sys_refcursor;
     curStr varchar2(1024) := 'select * from ' || TableName;
begin
     open cur for curStr;
     loop
          fetch cur into rec;
          exit when cur%notfound;
          dbms_output.put_line ('value = ' || rec.val);
     end loop;
end;
insert into TestTab1 (val) values (1);
insert into TestTab1 (val) values (2);
insert into TestTab1 (val) values (3);
insert into TestTab1 (val) values (4);
insert into TestTab2 (val) values (101);
insert into TestTab2 (val) values (102);
insert into TestTab2 (val) values (103);
insert into TestTab2 (val) values (104);
begin TestProc('TestTab1'); end;
begin TestProc('TestTab2'); end;
/regards,
Frank

How to pass Table name as parameter

For example, you have several tables (TableA, TableB, TableC...TableN) that have the same structure.
Ex.
CREATE TABLE TableA(
id VARCHAR(5),
name VARCHAR(20)
CREATE TABLE TableB(
id VARCHAR(5),
name VARCHAR(20)
And you want to create a stored procedure in Oracle that can be used for all of the tables (TableA, TableB, ...)
Ex. SELECT * FROM <tablename>
WHERE ID > 1;
How do you write the prepareCall and Callable Statement for that?
Thanks in advance.

You can't, not directly.
You have two choices:
-Write the SQL in java, then you can use string concatenation.
-Use 'dynamic sql' in Oracle. There is a standard package that will take dynamic sql and run it.

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;

Is it possible to pass TABLE as the output parameter in stored procedure

Hey Experts,
Is it possible to pass TABLE as the output parameter in stored procedure.
eg
create procedure spGetData
@tableName as TABLE(intValue INT NOT NUL)
as

You can use OPENQUERY or OPENROWSET, as mentioned above, to make stored procedure results table like. There are
some limitations with these methods:
http://technet.microsoft.com/en-us/library/ms188427.aspx
In OPENQUERY this-sql-server-instance can be used instead of a linked server name. It requires setting data accces server option:
exec sp_serveroption @server = 'PRODSVR\SQL2012'
,@optname = 'DATA ACCESS'
,@optvalue = 'TRUE'

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?
