Pasing table name as parameter

hiiii
i have the following PROCEDURE ..
i want the table name in the FROM clause to be (user_table) ... but its not working in the way am using now ... HOW can i do that ??
PROCEDURE LOGIN(u_name varchar2,PWD varchar2,user_table varchar2) IS
nm varchar2(50);
BEGIN
select F_NAME into nm from user_type ;
END;
thanx in advance

hiii
thanx for replying
i used the following
PROCEDURE LOGIN(u_name varchar2,PWD varchar2,user_type varchar2) IS
nm varchar2(50);
BEGIN
execute immediate 'select f_name from ' || user_table into nm;
END;
i got the following error
This feature is not supported in client-side programs
identifier 'USER_TABLE' must be declared

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

Well, I would say (ugly as it is) String concatenation, or stored procedures.

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 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.

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,

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?

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

, val anydata
create or replace type my_parms as table of my_parm
create table t1( c1 number, c2 varchar2(10), c3 date )

p_stmt2 varchar2(32000);
ind pls_integer;
curs integer;
dummy integer;

t_n number;
t_d date;
begin
curs := dbms_sql.open_cursor;
if upper( p_action ) = 'I'
then
    ind := parms.first;
    loop
      exit when ind is null;
      p_stmt1 := p_stmt1 || ', ' || parms( ind ).name;
      p_stmt2 := p_stmt2 || ', :b' || to_char( ind );
      ind := parms.next( ind );
    end loop;
    p_stmt1 := 'insert into ' || p_tab || ' (' || substr( p_stmt1, 2 ) || ' ) values (' || substr( p_stmt2, 2 ) || ' )';
    dbms_sql.parse( curs, p_stmt1, dbms_sql.native );
    ind := parms.first;
    loop
      exit when ind is null;
      case parms( ind ).val.GetType( t_a )
        when dbms_types.typecode_varchar2
        then
          dummy := parms( ind ).val.GetVarchar2( t_v );
          dbms_sql.bind_variable( curs, ':b' || to_char( ind ), t_v );
        when dbms_types.typecode_number
        then
          dummy := parms( ind ).val.GetNumber( t_n );
          dbms_sql.bind_variable( curs, ':b' || to_char( ind ), t_n );
        when dbms_types.typecode_date

Writing procedure using table name as parameter

I want to write a procedure to sample size any table. It could be employees, departments, etc. It will not know anything about the table (what table, columns, datatypes) until it is called.
I want to invoke it sample_size(table_name_in, table_name_out, sample_sz).
Table_out will be created and empty. It will determine the columns to be selected from table_in.
It is a given that all columns in table_out exist in table_in with same name/datatypes.
Pseudocoding:
determine increment using size of table_in and sample_sz
build out_var list from table_out
select out_list from table_in
for (rows in table_in) loop by increment
insert into table_out
end for
I wrote function to get cursor:
create or replace
FUNCTION get_cursor
(table_nm IN VARCHAR2,
flds IN VARCHAR2)
RETURN sys_refcursor
IS
cur sys_refcursor;
vQry VARCHAR2(4000);
BEGIN
vQry := 'SELECT ' || flds || ' FROM ' || table_nm;
OPEN cur FOR vQry;
RETURN cur;
END get_cursor;
What I cannot figure out is how to define rowtype in calling procedure:
PROCEDURE
sample_size( table_in IN VARCHAR2,
table_out IN VARCHAR2,
sample_sz IN NUMBER )
IS
c1 sys_refcursor;
vInto VARCHAR2(4000);
BEGIN
-- code to get variables desired into variable vInto (I know how to do this)
c1 := get_cursor(table_in,vInto);
LOOP
FETCH c1;
EXIT WHEN c1%NOTFOUND;
-- code to decide wether to insert row into table_out
END LOOP;
CLOSE c1;
END sample_size;
I get error on FETCH c1; line:
Error(47,15): PLS-00103: Encountered the symbol ";" when expecting one of the following: . into bulk
All discussions I found about subject will have something similar to:
Rec emp%rowtype
and then
fetch c1 into Rec
None of the discussions showed me how to process an unknown table.
If tomorrow someone tells me to sample_size table CITIES, I want to use function without having to change it.
This is my first post. I hope I gave enough information. Thanks for any answer.

Welcome to the forum.
If yours is not an exercise why you don't want to use just
<tt><b>[url http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_10002.htm#SQLRF01702]select * from table_name {sample_clause}</b></tt> ;)

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.

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;
Regards.

Use table name in UPDATE statement as variable

Hi All,
I am using ORACLE 9i AIX base. I want to write following procedure:
PROCEDURE update_header (
p_care_msg_nbr IN NUMBER,
p_care_msg_id IN NUMBER,
p_care_msg_gkey IN NUMBER,
p_old_status IN VARCHAR2,
p_new_status IN VARCHAR2
IS
l_table varchar2(50);
BEGIN
l_table := 'CARE_EDI_MESSAGES';
UPDATE '&l_table'
SET status = p_new_status,
changed = sysdate,
changer = user
WHERE care_msg_no = p_care_msg_nbr
AND care_msg_id = p_care_msg_id
AND gkey = p_care_msg_gkey
AND status = p_old_status;
END;
I want to give the table name by passing value in a variable or parameter. Is it the write way or can I do this function in any other way.
Pleae tell me in urgency.
Thanks & Regards

This implies that you have several tables with identical or near identical structures, otherwise you will get errors if any of the mentioned columns do not exist in the table passed but ...
You cannot use a substitution variable that way. Oracle will ask for a value when you try to create the procedure, and compile what ever value you supply into the procedure viz.
SQL> CREATE PROCEDURE p AS
2 l_id NUMBER;
3 BEGIN
4     SELECT id INTO l_id FROM &t;
5 END;
6 /
Enter value for t: T
old   4:    SELECT id INTO l_id FROM &t;
new   4:    SELECT id INTO l_id FROM T;
Procedure created.
SQL> SELECT text FROM user_source WHERE name = 'P'
2 ORDER BY line;
TEXT
PROCEDURE p AS
l_id NUMBER;
BEGIN
   SELECT id INTO l_id FROM T;
END;Even if that is the effect you want, note that there are no quotes around the substitution variable in the CREATE statement.
If you want to be able to pass the name of the table to the procedure, then you need to make the table name a parameter, then build the sql statement and execute it using EXECUTE IMMEDIATE. Something more like:
PROCEDURE update_header (p_care_msg_nbr IN NUMBER,
                         p_care_msg_id   IN NUMBER,
                         p_care_msg_gkey IN NUMBER,
                         p_old_status    IN VARCHAR2,
                         p_new_status    IN VARCHAR2,
                         p_table         IN VARCHAR2) IS
l_sqlstr VARCHAR2(4000);
BEGIN
   l_sqlstr := 'UPDATE '||p_table||' SET status = :b1 '||
               'changed = sysdate, changer = user '||
               'WHERE care_msg_no = :b1 and care_msg_id = :b3 and '||
               'gkey = :b4 and status = :b5';
   EXECUTE IMMEDIATE l_sqlstr
      USING p_new_status, p_care_msg_nbr, p_care_msg_id, p_care_msg_gkey, p_old_status;
END;HTH
