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.

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.

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!

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.

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).

You cannot use a (bind) variable in SQL for an object name (i.e. a table name, column name, etc).
Why?
The SQL engine needs to parse the SQL. Part of the parse is to resolve the scope to determine what objects are being reference. It needs to check that the column names referred to is indeed in that object. Etc.
Then these objects are used to determine the best execution path to run the SQL. What indexes do the objects have? Is the object a partitioned table and the partition criteria used in the predicate? Etc.
How can the SQL engine perform any of these when you pass it a table name that is a parameter?
The name of an object (such as the table being selected from) must be explicitly stated in a SQL statement. It cannot be variable.

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.

How to pass file name as parameter into url: or fo:external-graphic src

Hello gurus,
In my rtf I want to dynamically get the name of the image file and display the image in the report. If use hard coded image file name it works but if I try to get the name into a variable and pass that variable it is not working.
Basically my client is having different logos for each operating unit. in the OA_MEDIA directory there are separate logos for each OU. during run time based on OU name we need to display the corresponding image. If I can get this entire path($OA_MEDIA/logo.jpg') in XML field<?CF_OU_LOGO?> then I'm able to print the logo using url:{CF_OU_LOGO}
But I'm using seeded data source and I cant modify the data source, I need to handle this in RTF only. I could able to get the file name into a variable but not sure how to pass to url.
could some one help me on this. I tried the following options
<fo:external-graphic src="url($ln)" />
url:{$ln} in web etc...
here 'ln' is the variable which holds '$OA_MEDIA/logo.jpg'. ln is defined as <xsl:variable name="ln" select=".//CF_OPERATING_UNIT" />
later I set the values as <?xdoxslt:set_variable($_XDOCTX, 'ln',translate( concat('${OA_MEDIA}/','Logo',.//CF_OPERATING_UNIT,'.jpg'),' ',''))?><?xdoxslt:get_variable($_XDOCTX, 'ln')?>
thanks,
Vijay

What version of EBS is the customer running? I read somewhere that in R12 all of the concurrent parameters are passed to the XMLP template. I have not tried this but if true. You could create a conc program parameter that would hold the location of the image. You could either have the user pick the image or maybe derive it from the other parameter choices.
Lets assume the token name is DLOGO you can reference that in your template.
<?param:DLOGO?>
this needs to be at the top of the template. Then where you need to embed the image just reference the value using
$DLOGO
You can embed this in the external graphic field
As I mentioned I have not tested it yet, hopefully its there, if not there are ways around it. Try it first.

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.

           WHERE bukrs = zbukrs
             AND belnr = zbelnr
             AND gjahr = zgjahr

             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;

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.

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?

How to use table name dynamically in report procedure

Hello every body
I want to use table name dynamically means at runtime i want to pass table name.
I can do this by lexical parameter in main query.
But my problem is that i want to crate new format trigger or new function that use 1 cursor in which that lexical parameter : table name is used.
so how to do that?
i can not use that lexical parameter it is giving error.
please help me how to do that.

Call a database function which you pass the lexical parameter. Then in the database function you use dynamic sql or the execute immediate option to build the SQL string.
Return the information from this function to build your business logic on in your format trigger.
