Passing table as (IN) parameter of an Oracle StoredProcedure
Hello,
I want to call an oracle 8.1.7 stored procedure define as:
CREATE TYPE Commande as object(Name varchar2(64), Type varchar2(2))
CREATE TYPE CommandeList as table of CommandeRapport
PROCEDURE Enregistrer (pListe IN CommandeList)
I can't use oracle.jdbc.driver.OracleCallableStatement
because I'm using the JDBC pooling of Weblogic (JDBC dataSource that gives me an java.sql.CallableStatement)
CallableStatement cs =
connection.prepareCall("{call Enregistrer(?)}");
what type of cs.set????(1, ????) do I have to use, while I cannot instanciate an "java.qsl.Array" object ?
I'm not using Weblogic JDBC driver but the Oracle thin driver for 8.1.7.
I want to use Weblogic JDBC pooling mecanism that gives me "weblogic.jdbc20.rmi.SerialConnection" (not OracleConnection)
My question is not about driver but "how to pass java array as a SQL ARRAY parameter to a Callable/PreparedStatement, using JDBC 2.0 standard API ?". Oracle specialized JDBC classes allow me to create "oracle.jdbc.ARRAY" objects. I used it for a test and it works fine, but I need JDBC pooling ...
Please help ... My boss is getting nervous !

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

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 PMYes, 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 adviceHi,

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).

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.

select owner, count(*) from all_objects

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 -

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:

Here's how to pass XML as a parameter to an Oracle stored proc

The first sample has exactly what you need in order to pass "XML" as a parm to a stored proc.
http://www.oracle-base.com/forums/viewtopic.php?f=2&t=8468> Really, what is the difference between the 2?
"What is a...?" questions are easily answered by Google. Generally speaking, however, "JavaScript" is Netscape's implementation of ECMAScript, a scripting language primarily for client-side development for a web browser. "Java" is an entire platform, but typically refers to an object-oriented programming language that is typically compiled to bytecode and run in a virtual machine.
They're not the same thing at all.

Oracle 9i - passing a string as parameter when integer is required yet
Dear all;
I am trying to fix this problem with a limited amount effort and also prevent redesigning it as well. I know it is completely wrong but it was done by a past developer and I am just trying to make a simple twick to it. I will try to explain my current problem so please bear with me
I have a table with a field called SN which is number type field, I have a select statement similar to this below
select stype from tbl_one where sn = 1ok, the select statement works for numbers and numbers with dash(e.g 03-2). In the case of numbers with dash, it returns null which is okay now, I am having a bit of problems where sometimes the user entry is a an actual string like this (cat). Now the select statement isnt going to work for this case because I am going to get a Ora-00904 - invalid identifier error.
The solution I had in mind is first use a regular expression to determine whether the parameter is a string or a numeric value and if it is a numer value pass it as a parameter to the select statment if not, then just return null in the select statement. However, since I am using oracle 9i I cant use regualr expression is there any suitable sql statment i can use in replacement of a regular expression or any other ideas.
All help is appreciated. Thank you.Hi,
user13328581 wrote:
... the select statement works for numbers and numbers with dash(e.g 03-2). That's actually not a number with a dash. That's a subtraction operation involving two numbers, 03 (which is the same as 3) and 2. 3 - 2 = 1, so it's the same as typing 1.

LTRIM ( s
, '0123456789'
) IS NOT NULLThe condition above will be TRUE when s contains anything other than a digit.
If you want to check for signs, decimal points, and scientific notation, then see this thread:

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.
JiaxinHi, 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?

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)
asYou 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'
