Benefit of using store procedure instead of select statement to pull data into biztalk

I was wondering why store procedure is more beneficial than using select statement to pull data into biztalk?

In addition to the above two points, in case if there is a change in logic of stored procedure, you only need to modify the stored proc and the applications calling/using it may be left intact.
Also, stored procedures are complied code so performance is better and safe too.

Use of a stored procedure in a select statement submitted to cx_oracle

Hi,
I am developping under python and I'm using the cx_oracle interface.
I've written a stored procedure that I've tested directly under sqlplus session : it's ok. I've also tested this stored procedure from python by using callproc routine : its also ok.
Now I need to use this procedure within a select statement that I submit to the execute statement of cx_oracle as :
s = "select a.airport_name,gmlpos.ExpLatLong(a.point_name) from airport"
self.db = oracledb('ops/opeope00@ACE2008B')
dbmsg = self.db.execute(s)
IF (dbmsg == "") :
An error occurs :
Message = request = select a.AIRPORT_NAME, gmlpos.ExpLatLong(a.point_name) from airport, errmsg = ORA-00904: "GMLPOS"."EXPLATLONG": invalid identifier
Noting that the execution of any other select (without stored procedure) order from python works fine.
Is anybody has a solution or workaround ?
thanks a lot for your help

The result gives what is expected :
AIRP
GMLPOS.EXPLATLONG(A.POINT_NAME)
LFLL
-45.71666666666667 -5.08333333333333
As I said the stored procedure works fine.
Thanks for your expertise
PS : why change the login password until nobody says which machine or database is concerned ?

Which is better to use Store Procedure or Views in Crystal Reports ?

Hi,
which one is more better to use Store Procedure or Views in Crystal Reports ?
Thanks.

It depeneds on the requirement. Well, but from performance point of view as u know that stored procedures are already compiled on DB side, they would be more efficient. Views are handled differently. Here CR has nothing to do with it.
But if the stored procedure u r using is having 2 Select statements, CR will only display the results from the first select statement. In that case you need to use Views as one can use more than one views in the report and join them.
Using a Generic view which is created by the DBA for a larger audience will result in performance issues meaning if a View "V" has 25 fields and View is based on 5 tables and ur report is using only 5 fields which are coming only from 2 tables inside the view,in this case u will end up in joining 3 more tables unnecessarily.
Hope this helps!

How to build a report in web Intelligence using Store procedure under Microsoft SQL Server 2000

Post Author: ltkin
CA Forum: WebIntelligence Reporting
Hi,
How to build a report in web Intelligence using Store procedure under Microsoft SQL Server 2000 ?
Regards,

Hi ltkin,
Unfortunately, it is not possible in Xir2 to create Webi reports from stored procedures.
Webi reports can only be created from Universe. So in Business Objects XIR3 we can create a special universe that enables Web Intelligence user's to access stored procedures residing in the database. This is the only way that Web Intelligence user's can access stored procedures.
Please let me know if the above information helps.

How to pass xml data as objects into Database using store procedures

Hi All,
     I don't have much knowledge on store procedure,can anybody help how to pass the xml as objects in Database using store procedure.
My Requirement is I have a table with three fields EMPLOYEE is table name and the fields are EMP_ID,EMP_TYPE AND EMP_DET,I have to insert the employees xml data into corresponding fields in the table.
Input Data
<ROWSET>
   <ROW>
     <EMP_ID>7000</EMP_ID>
      <EMP_TYPE>TYPE1</EMP_TYPE>
     <EMP_DET>DEP</EMP_DET>
<ROW>
<ROW>
     <EMP_ID>7000</EMP_ID>
     <EMP_TYPE>TYPE2</EMP_TYPE>

    <EMP_DET>DEP3</EMP_DET>
<ROW>
<ROWSET>
So each row values has to inserted into resp fields in the table.

Do you have a similar structure in your stored procedure ?
In that case you can simply call the procedure from soa using db adapter and do a mapping to assign the values.

Use of cursors insted of select statements

could any one please explain what is the advantage of using cursors instead of simple select statements
thanks
siby

A benefit to using an explicit cursor rather than a select statement, is for the NO_DATA_FOUND exception. Its kind of like a free IF statment. IF no data is found, then stop.
if you write a select statement, and no data is returned, you SHOULD code for the NO_DATA_FOUND exception. Often people say, "i'll ALWAYS get a row returned". but you should always cover your code "just in case". so you must code an exception...
declare
v_var varchar2(1);
procedure do_something(p_parm varchar2) is
begin
null;
end do_something;
procedure log_error is
begin
null;
end log_error;
begin <<main>>
do_something('x');
begin <<selectblock>>
select dummy
into v_var
from dual
where dummy = 'a';
do_something(v_var);
exception
when no_data_found then
log_error;
end selectblock;
do_something (v_var||'abc');
end main;
if you use an explicit cursor instead, you don't need to code for the NO_DATA_FOUND. If an explicit cursor opens and finds no rows, there are simply no rows. of course, you don't need a loop if you expect only 1 row returned under normal circumstances.
BTW, don' forget that SQL%ROWCOUNT and your_cursor%ROWCOUNT are not initialized. There is a null, until a row is successfully fetched. therefore if no rows are returned at all, %ROWCOUNT is NULL.
declare
v_var varchar2(1);
cursor my_cur is
select dummy
from dual
where dummy = 'a';
procedure do_something(p_parm varchar2) is
begin
null;
end do_something;
procedure log_error is
begin
null;
end log_error;
begin << main>>
for cur_rec in my_cur loop
dbms_output.put_line('inside');
begin <<loop_block>>
if nvl(my_cur%rowcount,0) > 1 then
do_something(cur_rec.dummy);
else
log_error;
end if;
end loop_block;
end loop;
end main;

Can we call a stored procedure in a select statement

Hi All
I want to call a stored procedure inside a select statement is this possible.
Regards
Sravz

You can create a pipelined function which gathers the data from your stored procedure and then use that in a select statement or directly write your script in any function or pipelined function. ;)
There is no way you can call any stored procedure in a SELECT statement directly - i guess.

Using pop-up value in select statement

Hello.
I want to select a value from a pop-up box and then use that value in a select statement for another pop-up. Is that possible?
The first pop-up is P39_PIIN_CALL but it is not recognized in the second pop-up when I use it in the select statemnt... select * from table where PIIN = :P39_PIIN_CALL. I get nothing back because it has no idea what :P39_PIIN_CALL is. I'm desperate and on a timeline.
Thanks,
Mark E

Hi,
After fetching the value from first popup the page should submit so that the value is availble to the second popup..
Edit the first popup.. and in HTML Form Element Attributes and enter onchange="doSubmit('MyRequest')"

Limitations in using a function within a select statement

I have a function which retrieves various data elements from the
database and formats it accordingly. The data (varchar2)
returned could be in excess of 2,000 characters length.
I need to use the returned data as part of a view. I am able to
use the function in a "select" statement, but when I use it with
returned data in excess of 2,000 chars, I get the following
error:
ORA-06502: PL/SQL: numeric or value error
This error is occurring whenever the returned data is in excess
of 2,000 characters.
Is there an alternative method to what I am proposing, I have
tried alternative data types but if I am able to use it in a
"select" statement, I get the above error when the returned
length exceeds 2,000 chars.
Thanks
Peter

are u using oracle 7. varchar2 limit in 8 is 4000.

Insert and update same record of table using store procedure in oracle 10g

Hi,
I am using oracle sql developer for this.
I have created Store procedure which run after every 30mins of interval.
the problem is Ii need to insert data for first time of day then later that same record should update for particular field(here its plan code).
if new field is coming (if new plan code is generated) then it should insert data and again update same for interval.
means for each plan individual record(i.e. plan wise summary) should be there for only a day. next day new record for same plan.

Hi,
You should use Merge like shown below:-
Merge into original_table a
using second_table b
on (a.primary_key=b.primary_key and a.primary_key........)
when match then
update set column_list=b.column_list
when not match then
isert into (column list)
values(a.column_list)If you dont know much about merge then follow below link..

Using store procedures with SQLJ - please help!

I have two questions:
1.I wrote simple test appllication that uses SQLJ to run store
procedures from SQL package. It compiles and work fine from
JDeveloper 3 if I use java version JDK1.2.2_JDeveloper.
It compiles OK in regular JDK1.2.2 but raise the following
exception when running:
profile
com.itrade.trserver.truser.dbqueries.ItrHistorian_SJProfile0 not
found: java.io.InvalidClassException: [Ljava.lang.Object;;
Serializable is incompatible with Externalizable
Does it mean that I have to use JDeveloper JDK?
2.When I give other then default package for *.sqlj file the
*.sqlj file is added to project but I cannot see it in specified
package (the *.sqlj file is created in the its directory).
After I compile the project the I can see *.java file in the
specified package, but compiler gives errors about redefined
symbols. If I remove *.sqlj file from the project it compiles OK.
What I am doing wrong?

Thank you for the response.
I don't create jar file. I run it from JDeveloper environment.
What do you mean by "I made sure to also copy over the
: the .ser file"? What purpose of the *.ser file in this case?

Master Data Service: how to remove the dirty data from master data service from a table using store procedure?

hello, we need to remove the dirty data from MDS, but we found we can only do this from MDS web, and we need to do this by store procedure to make this process automatically. is there any easy method to remove the data from MDS automatically? thank.
Warren

Hi Warren,
Assuming the dirty data is easily identifiable, all you need to do is use the staging process with import type of 5 (de-activate - i.e., soft delete) or import type of 6 (hard delete).
Could give more details if I knew the version of MDS you are running (SQL 2008R2 or SQL 2012).
Kind regards,

Using Store Procedures with BC4J - Help

I need some help, could you explain me how to call some store procedures on an Entity Object with a source code.
I really apreciate your help.
null

You can override the doDML method.
Then I get the connection using the getDBTransaction() method.
After that you can include your code in order to invoke the stored procedure.
Example:
public void doDML(int operation, TransactionEvent e) {
CallableStatement stmt = null;
if (operation == DML_INSERT)
// Prepare JDBC CallableStatement with the Stored Procedure Call
String plStr = "XXXXXX";
stmt = getDBTransaction().createCallableStatement(plStr , 1);
Other way:
Create a method in the view objet and make it a client method.
You can get the appmodule and the DBTransaction in this method.
In both cases you are using the same connection.

Execute store procedure( in Id, in out RefCursor), and data fetched in ref cursor should be sent out as excel sheet.

I am trying to make a ssis package that get the data calling the store proc with two param one is ID and other is Sys_refcursor. Say Store Proc as ListName(Id int, myCur sys_refcursor), which gets the datas with the conditions inside it.
REATE OR REPLACE PROCEDURE schemaName.LISTNAME (P_ID IN INT, LST_NAME_REFCUR IN OUT SYS_REFCURSOR)
IS
P_NAMESOURCE_ID INT;
BEGIN
SELECT SOURCE_ID INTO P_NAMESOURCE_ID FROM SEARCHING_TABLE ST WHERE ST.ID = P_ID;
IF (P_NAMESOURCE_ID=1)
THEN
OPEN LST_SOURCE_REFCUR FOR
SELECT ST.ID,
ST.TRANSACTION_DATE AS TRAN_DATE,
IF (P_NAMESOURCE_ID=1)
THEN
OPEN LST_SOURCE_REFCUR FOR ....
then i need to get the data from that refcursor and fetch those data to excel sheet to a virtual directory.
Any help would be appreciated. I am new to SSIS. and i need to do this assignment this friday.

Hi 11srk,
To fetch data from Oracle store procedure, you can use a Script Component as source to call the Oracle stored procedure by using System.Data.OracleClient OracleDataReader, and get the rows and add them to the pipeline buffer. For more information, please
