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.

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?

Passing table name as a parameter

Hi:
I have a question regarding passing part of a table name to crystal. I have table getting created everyday and the dynamic part being Table_<date in yymmdd format>, for e.g. - Table_20140225 for table created on 02/25/2014
I have written query like "select * form Table_{@DT}". This used to work in Crystal 11.5.8.826. but recently we upgraded to 12.2.0.290. In this version of Crystal it is not working and giving me error "com.crystaldecisions.sdk.occa.report.lib.ReportSDKServerException: Missing parameter values.---- Error code:-2147217394 Error code name:missingParameterValueError".
Can you please suggest to get around this problem. Running a stored procedure with REFCURSOR is not an option.
i tried another solution, where i just wrote a stored procedure to do a insert into a table handling the dynamic table in stored procedure. but to my surprise, the stored procedure doesn't execute all the time.
Any help on this is much appreciated...

Please see if SP 6 helps. You are on SP 2 at this time.

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

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).

How to pass column name at run time in function.

how to pass column name at run time in function as parameter.
thank in advance
pramod patel

Hello,
Using dynamic sql you can pass column name to function. well I am not getting what you really want to do ? Please write in more detail. By the way I am providing one example here. see it uses dynamic sql.
Create or replace function fun_updtest (p_columnname_varchar2 in varchar2,
p_value_number in number)
return number is
v_stmt varchar2(500);
begin
v_stmt := 'update emp
set '||p_columnname_varchar2||' = '||to_char(p_value_number)||'
where empno = 7369';
execute immediate v_stmt;
return 0;
commit;
end;
call to this function can be like this..
declare
v_number number;
begin
v_number := fun_updtest('SAL',5000);
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 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 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;

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 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..
Thanks & regards,

You shouldn't do it, but if you do, you can use something like this:
Anton
create or replace type my_parm as object

create or replace type my_parms as table of my_parm
create table t1( c1 number, c2 varchar2(10), c3 date )
create or replace procedure doital( p_action in varchar2, p_tab in varchar2, parms in my_parms )
is
p_stmt1 varchar2(32000);
p_stmt2 varchar2(32000);
ind pls_integer;
curs integer;
dummy integer;
t_a anytype;
t_v varchar2(32000);
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
        then
          dummy := parms( ind ).val.GetDate( t_d );
          dbms_sql.bind_variable( curs, ':b' || to_char( ind ), t_d );
      end case;
      ind := parms.next( ind );
    end loop;
end if;
dummy := dbms_sql.execute( curs );
dbms_sql.close_cursor( curs );
end;
begin
doital( 'I', 't1', my_parms( my_parm( 'c2', anydata.ConvertVarchar2( 'testje' ) )
                             , my_parm( 'c1', anydata.ConvertNumber( 3 ) )
                             , my_parm( 'c3', anydata.ConvertDate( sysdate ) )
doital( 'I', 't1', my_parms( my_parm( 'c1', anydata.ConvertNumber( 77 ) )
                             , my_parm( 'c2', anydata.ConvertVarchar2( 'goedzo' ) )
