Using ref cursor in "in clause" in select statement
Hi,
Is there any way can we use the ref cursor in the in condition of a select statement.
Regards,
Venkat.

I'm sorry if I post in confusing way. I will give an example. Just see the psudo code here.
declare

begin
pr_test(empno,rf_cur);
-- rf_cur returning emp names.
select * from emp
where empname in (ref_cusor results);-- here i want to consume my ref cursor result in the in conditions.
end;
Thanks &Regards,
Venkat.No you can't do that. A ref cursor is not a set of results as you believe.
Take a read of this article...

Using ref cursor in where clause
I have a stored procedure (package procedure) that returns a ref cursor as a parameter. This procedure performs a query and returns the cursor. The procedure calls another stored procedure within the package. This second procedure also returns a ref cursor. I want to do my query on the results of the cursor returned by the second procedure. Hopefully the example below is okay.. "I had to change names to protect the blah blah...."
For example:
TYPE out_cursor IS REF CURSOR;
TYPE IDTable IS TABLE OF table1.ID%TYPE;
PROCEDURE A
v_ID IN NUMBER,
v_Param2 IN NUMBER,
v_FromClause IN VARCHAR2, -- ignore for now
v_WhereClause IN VARCHAR2, -- ignore for now
v_retval OUT NUMBER,
the_cursor OUT out_cursor
IS
v_SQLString VARCHAR2(2048);
v_cursor1 out_cursor;
v_tabIDs IDTable;
BEGIN
v_SQLString := '';
packageA.procedureA(v_ID, v_retval, v_cursor1);
-- this does not work
-- I get ORA-00942: table or view does not exist
v_SQLString := 'select distinct * from v_cursor1';
-- I found this on the message board but
-- it did not compile.
-- local collection types not allowed in SQL statements
FETCH v_cTSFiles BULK COLLECT INTO v_tabIDs;
v_SQLString := 'select distinct * from table1 WHERE table1.ID in (select * from table(v_tabIDs))';
OPEN the_cursor FOR v_SQLString;
END;You can use that second technique but as the error message says, "local collection types not allowed in SQL statements". You need to create a schema type instead.

Use of LIKE in where clause of select statement for multiple records
Hi Experts,
I have a account number field which is uploaded from a file. Now this account numbers uploaded does not match fully with sap table account numbers but it contains all of the numbers provided in the file mostly in the upright positions.
For example in file we have account number as 2ARS1 while in sap table the value is 002ARS1.
And i want to fetch data from sap table based on account number uploaded. So, i am trying to use LIKE with for all entries but its not working as mentioned below but LIKE is not working with FOR ALL ENTRIES.
data : begin of t_dda occurs 0,
dda(19) type c,
end of t_dda.
data : begin of t_bukrs occurs 0,
bukrs type t012k-bukrs,
end of t_bukrs.
data : dda type t012k-bankn,
w_dda type t012k-bankn.
CONCATENATE '%'
'2ARS1'
INTO W_DDA.
MOVE W_DDA TO T_DDA-DDA.
APPEND T_DDA.
CLEAR T_DDA.
free t_bukrs.
SELECT BUKRS
FROM T012K
into TABLE t_bukrs
for all entries in t_dda
WHERE BANKN like t_dda-dda.
Can anybody suggest what should i use to get the data for multiple account numbers using one select statement only instead on using SELECT UP TO 1 ROWS in LOOP....ENDLOOP ?
Thanks in advance,
AkashHi,
yes, For All entries won't work for LIKE with '% '.
I think the other alternative is go for Native SQL by writing sub-query
sample code is here:
data: begin of i_mara occurs 0,
matnr like mara-matnr,
matkl like mara-matkl,
end of i_mara.
exec sql.
select matnr, matkl from mara where matnr in (select matnr from marc) and matnr like '%ma' into :i_mara
endexec.
loop at i_mara.
write:/ i_mara-matnr, i_mara-matkl.
endloop.
hope u got it.
regards

How to access variable number of columns using ref cursor !
Hi,
I am trying to get variable number of columns using ref cursor.
Declare
mySzSql varchar2(2000);
Type dynSqlRC is Ref cursor;
current_cur dynSqlRC;
tbl_rec alt_42_consolidated%Rowtype;
Begin:
/* This works */
mySzSql := 'select *
from
Table1
Where
rowid = ''AAEWNEABXAAAAkxAAA''';
/* i want something like this to work, this is not working, giving missing variable name error */
mySzSql := 'select col1, col2, col3
from
Table1
Where
rowid = ''AAEWNEABXAAAAkxAAA''';
open current_cur for mySzSql;
fetch current_cur into tbl_rec;
close current_cur;
End;
I do have the list of desired columns which I am looking to fetch, so after taking that in the record type, how should i get their values. Is it possible to traverse tbl_rec declared above and if column name matches then I will store the value in the array and finally return this array.
Can somebody please tell me how to do this.
ThanksIt appears that this is a followup to How to loop through columns selected by select clause which is itself a followup to [url="
How to execute dynamic sql"]this earlier thread.
Assuming these are intended to be followup questions, can we please stick to a single thread? That makes it a lot easier to understand the situation and follow the conversation. Starting multiple threads makes it harder to follow the conversation.

Report using ref cursor or dynamic Sql
Hi,
I never create a report using a ref cursor or a dynamic sql. Could any one help me to solve the below issue.
I have 2 tables.
1. Student_Record
2. Student_csv_help
Student_Record the main table where the data is stored.
Student_csv_help will contain the all the column names of the Student_record.
CREATE TABLE Student_CSV_HELP

Insert into Student_record
(S_ID, S_Name, S_Join_date, S_Address,S_Fee)
Values

Commit;
Now my requirement is:
I have a form with Student_record data block. When i Click on print Button on this form. It will open another window which has Student_CSV_HELP.DESC_NAME and a check box before this.
The window look like as below:
check_box DESC_NAME+
X S_ID+
-- S_Name+
X S_Join_date+
X S_Address+
-- S_Fee+
X means check box checked.+
-- means check box Unchecked.+
After i selected these check boxes i will send 2 parameters to the report server
1. a string parameter to the report server which has the value 'S_ID,S_Join_date,S_Address' (p_column_name := 'S_ID,S_Join_date,S_Address');
2. the s_id value from the student_record block (p_S_id := '101');
Now my requirement is when i click on run. I need a report like as below:
Student ID : 101+
Joining Date : 12/17/2009 08:00:00+
Address : CA-94777+
This is nothing but the ref cursor should run like as below:
Select S_id from student_record block S_id = :p_S_id;
Select S_Join_date from student_record block S_id = :p_S_id;
Select S_Address from student_record block S_id = :p_S_id;
So, according to my understanding i have to select the columns at the run time. I dont have much knowledge in creating reports using ref cursor or dynamic sql.
So please help me to solve this issue.
Thanks in advance.Plain sql should satisfy your need. Try ....
Select S_id, S_Join_date, S_Address
from student_record
where S_id = :p_S_id -
Cursors are not closed when using Ref Cursor Query in a report ORA-01000
Dear Experts
Oracel database 11g,
developer suite 10.1.2.0.2,
application server 10.1.2.0.2,
Windows xp platform
For a long time, I'm hitting ORA-01000
I have a 2 group report (master and detail) using Ref Cusor query, when this report is run, I found that it opens several cursors (should be only one cursor) for the detail query although it should not, I found that the number of these cursors is equal to the number of master records.
Moreover, after the report is finished, these cursors are not closed, and they are increasing cumulatively each time I run the report, and finally the maximum number of open cursors is exceeded, and thus I get ORA-01000.
I increased the open cursors parameter for the database to an unbeleivable value 30000, but of course it will be exceeded during the session because the cursors are increasing cumulatively.
I Found that this problem is solved when using only one master Ref Cursor Query and create a breake group, the problem is solved also if we use SQL Query instead of Ref Query for the master and detail queries, but for some considerations, I should not use neither breake group nor SQL Query, I have to use REF Cursor queries.
Is this an oracle bug , and how can I overcome ?
Thanks

Using ref cursor in after parameter form in reports
hi everyone,
I have problem in usage of ref cursor in after parameter form. My actual requirement is I have user parameter :p_minval, :p_maxval. The values into these user parameters will be coming dynamically using sql_statement as shown below
select min(empid),max(empid) into :p_minval, :p_maxval from emp where empid in (:p_emp);
I will be writing this query in the after parameter form
:p_emp is a lexical parameter as per me but the after parameter form is taking it as a bind variable. so I decided to define a ref cursor and then use it for retrieve. But when I use ref cursor it is returning pl/sql error 591 saying that this is not supported by client side can anyone help me plz..
The following is the code i tried to use in after parameter form
function afterPform return boolean is
type rc is ref cursor;
l_rc rc;
sqlstmt varchar2(512);
begin
sqlstmt:='select min(empid),max(empid) from emp where empid in ('||:p_emp||')';
open l_rc for
select max(empid) from emp where empid in ('||:p_emp||')';
fetch l_rc into :p_maxval;
close l_rc;
return(true);
end;
thanks & regards

I tried to call proc ORDER_RETURN1 with the help of proc ORDER_RETURN2, but no change, it gives me same error if i call the first proc ORDER_RETURN1 or i call ORDER_RETURN2.
I am stuck with this problem, I had used ref cursor in procedure but not able to call the procedure which uses ref cursor as OUT parameter.
Please help me to resolve this.

Procedure to fetch table records using ref cursor
Hi
i need to fetch all the records in the table using ref cursor.we need to pass table
name and the out paramater should be ref cursor.
CREATE OR REPLACE PROCEDURE gettable(p_table_name IN VARCHAR2,
p_ref_cursor OUT dept_pack.ref_cursor1)
IS
BEGIN
OPEN p_ref_cursor FOR SELECT * FROM p_table_name;
END gettable;
is that a start ? then after this i have to execute this procedure to fetch the data from table. i am getting error that table doesnot exist but my idea was to pass p_table_name as IN parameter.
Thnks in Advancehere is the example

How to update data returned using REF CURSOR
Hi all,
I am trying to update updated data in a gridview but the update button seem to do nothing as i retrieve data using REF CURSOR.
Let me describe the architecture of my application first. I'm trying to implement best practice whenever possible. I am following the data access tutorial published in www.asp.net , the only difference is that i have an Oracle (10g) database. So I split my application into three layers, data access, business logic, and presentation layer. I'm also writing all queries in an Oracle package.
So I have my Oracle packages that perform CRUD operations. Then I have an xsd file that define dataTable based on the package procedure. My business logic layer then calls functions defined in the xsd file. And finally a detailsView control that uses an ObjectDataSource to call business logic functions.
In a nutshell, I am just trying to update records retrieved using REF CURSOR. Your help is very much appreciated. Please let me know if further details are required. Cheers,In the DataSet (xsd) where your DataTable is defined, you just need to add additional methods to the TableAdapter to handle insert, update and delete, either with SQL or by mapping to stored procedures.
Alternatively in code, create an OracleDataAdapter and supply its InsertCommand, UpdateCommand and DeleteCommand.

Thanks !!Hi Raj,
I am able to use the REF cursor with BPEL.
I am able to pass the resultset from Database using a REF cursor to a BPEL variable .
When you create a BPEL variable , create it with message type as the output message type of the REF Cursor.
