How to convert PL/SQL table to ref_cursor

Hi,
Can anyone provide a sample procedure to accecpt a PL/SQL table and ouput a ref cursor?
Thanks
Vimal

The nested table must be a SQL type (not a package level type).

How to convert from SQL Server table to Flat file (txt file)

I need To ask question how convert from SQL Server table to Flat file txt file

Hi
1. Import/Export wizened
2. Bcp utility
3. SSIS
1.Import/Export Wizard
First and very manual technique is the import wizard. This is great for ad-hoc and just to slam it in tasks.
In SSMS right click the database you want to import into. Scroll to Tasks and select Import Data…
For the data source we want out zips.txt file. Browse for it and select it. You should notice the wizard tries to fill in the blanks for you. One key thing here with this file I picked is there are “ “ qualifiers. So we need to make
sure we add “ into the text qualifier field. The wizard will not do this for you.
Go through the remaining pages to view everything. No further changes should be needed though
Hit next after checking the pages out and select your destination. This in our case will be DBA.dbo.zips.
Following the destination step, go into the edit mappings section to ensure we look good on the types and counts.
Hit next and then finish. Once completed you will see the count of rows transferred and the success or failure rate
Import wizard completed and you have the data!
bcp utility
Method two is bcp with a format file http://msdn.microsoft.com/en-us/library/ms162802.aspx
This is probably going to win for speed on most occasions but is limited to the formatting of the file being imported. For this file it actually works well with a small format file to show the contents and mappings to SQL Server.
To create a format file all we really need is the type and the count of columns for the most basic files. In our case the qualifier makes it a bit difficult but there is a trick to ignoring them. The trick is to basically throw a field into the
format file that will reference it but basically ignore it in the import process.
Given that our format file in this case would appear like this
9.0
9
1 SQLCHAR 0 0 """ 0 dummy1 ""
2 SQLCHAR 0 50 "","" 1 Field1 ""
3 SQLCHAR 0 50 "","" 2 Field2 ""
4 SQLCHAR 0 50 "","" 3 Field3 ""
5 SQLCHAR 0 50 ""," 4 Field4 ""
6 SQLCHAR 0 50 "," 5 Field5 ""
7 SQLCHAR 0 50 "," 6 Field6 ""
8 SQLCHAR 0 50 "," 7 Field7 ""
9 SQLCHAR 0 50 "n" 8 Field8 ""
The bcp call would be as follows
C:Program FilesMicrosoft SQL Server90ToolsBinn>bcp DBA..zips in “C:zips.txt” -f “c:zip_format_file.txt” -S LKFW0133 -T
Given a successful run you should see this in command prompt after executing the statement

bcp import completed!
BULK INSERT
Next, we have BULK INSERT given the same format file from bcp
CREATE TABLE zips (
Col1 nvarchar(50),
Col2 nvarchar(50),
Col3 nvarchar(50),
Col4 nvarchar(50),
Col5 nvarchar(50),
Col6 nvarchar(50),
Col7 nvarchar(50),
Col8 nvarchar(50)
GO
INSERT INTO zips
SELECT *
FROM OPENROWSET(BULK 'C:Documents and SettingstkruegerMy Documentsblogcenzuszipcodeszips.txt',
FORMATFILE='C:Documents and SettingstkruegerMy Documentsblogzip_format_file.txt'
) as t1 ;
GO
That was simple enough given the work on the format file that we already did. Bulk insert isn’t as fast as bcp but gives you some freedom from within TSQL and SSMS to add functionality to the import.
SSIS
Next is my favorite playground in SSIS
We can do many methods in SSIS to get data from point A, to point B. I’ll show you data flow task and the SSIS version of BULK INSERT
First create a new integrated services project.
Create a new flat file connection by right clicking the connection managers area. This will be used in both methods
Bulk insert
You can use format file here as well which is beneficial to moving methods around. This essentially is calling the same processes with format file usage. Drag over a bulk insert task and double click it to go into the editor.
Fill in the information starting with connection. This will populate much as the wizard did.
Example of format file usage
Or specify your own details
Execute this and again, we have some data
Data Flow method
Bring over a data flow task and double click it to go into the data flow tab.
Bring over a flat file source and SQL Server destination. Edit the flat file source to use the connection manager “The file” we already created. Connect the two once they are there
Double click the SQL Server Destination task to open the editor. Enter in the connection manager information and select the table to import into.
Go into the mappings and connect the dots per say
Typical issue of type conversions is Unicode to non-unicode.
We fix this with a Data conversion or explicit conversion in the editor. Data conversion tasks are usually the route I take. Drag over a data conversation task and place it between the connection from the flat file source to the SQL Server destination.
New look in the mappings
And after execution…
SqlBulkCopy Method
Sense we’re in the SSIS package we can use that awesome “script task” to show SlqBulkCopy. Not only fast but also handy for those really “unique” file formats we receive so often
Bring over a script task into the control flow
Double click the task and go to the script page. Click the Design script to open up the code behind

How to use PL/SQL table

Hi all,
can you guys suggest me how can I use pl/sql tables for the below query to incresing the performance.
DECLARE
    TYPE cur_typ IS REF CURSOR;
    c           cur_typ;
    total_val varchar2(1000);

                    where updateddate > '01-JUN-13'
                    and path is not null

      EXIT WHEN imgname_cur%NOTFOUND;
      total_val := 'EMC_Image_C_' || imgname_rec.cs_ownerid;
      sql_stmt := 'SELECT instr(textvalue,''' || total_val || '''), cs_ownerid FROM EMC_FTW_PREVA.EMC_Content_C_Mungo a Where cs_attrid = (select id from EMC_FTW_PREVA.EMC_ATTRIBUTE where name = ' || '''' || 'Body_freeform' || '''' || ')';

          FETCH c INTO freeform_id,freeform_name;
          EXIT WHEN c%NOTFOUND;
                                  IF freeform_id > 0 THEN
            dbms_output.put_line (imgname_rec.cs_ownerid || ',' || total_val || ',' || freeform_id || ',' || freeform_name);

        END LOOP;
        CLOSE c;
   END LOOP;
   CLOSE imgname_cur;
END;
Thanks in Advance.

can you guys suggest me how can I use pl/sql tables for the below query to incresing the performance.
There would be absolutely no point at all in improving the performance of code that has NO benefit.
The only result of executing that code is to possibly produce some lines of output AFTER the entire procedure if finished:
dbms_output.put_line (imgname_rec.cs_ownerid || ',' || total_val || ',' || freeform_id || ',' || freeform_name);
So first you need to explain:
1. what PROBLEM you are trying to solve?
2. why you are trying to use PL/SQL code to solve it.
3. why are you using 'slow by slow' (row by row) processing and then, for each row, opening a new cursor to query more data?
You should be using a single query rather than two nested cursors. But that begs the question of what the code is even supposed to be doing since the only output is going to a memory buffer.

How to convert pl/sql code into java/j2ee

Hi,
We have a PL/SQL Oracle App server application that we will support if we can convert in j2ee/java. But when i did take a look at the code, these pl/sql contains all HTML and java code inside the stored procedures.
And iam looking to explore some tools and mechanisms that can convert these pl/sql in a JAVA application so that i can deploy this new app into my BEA81 environment.
Does any body has any idea:
a) How to convert from pl/sql > java ?
b) Any plugins or tools of BEA that can run these pl/sql (the way thay are currently...i.e w/o converting) in BEA 81 container ?
thanks, sangita

these pl/sql contains all HTML and java code insideJava or JavaScript. They are not the same. I wouldn't expect to see Java inside html, whereas JavaScript would be intermixed. On the other hand you might have a java stored proc (Oracle 9/10) which is generating HTML.
>
Does any body has any idea:Refactor.
I doubt it just has html and JavaScript/Java. So what you have is a mess that mixes several things that should have been seperate in the first place.

Who know how to handle pl/sql table return from stored procedure calling from jsp

I have some stored procedure which return pl/sql table (index by table), It is look like an array. how jdbc handle this?
CallableStatement cs = con.prepareCall("EXECUTE bill.getcountry(?,?)");
cs.setInt(1, cid);
cs.registerOutParameter(2, java.sql.Types.VARCHAR);// ARRAY?
ResultSet rs = cs.executeQuery();
Array array = (Array) rs.getObject (1);
ResultSet array_rset = array.getResultSet ();

Not that familiar with the OCI (Oracle Call Interface), but I think this call will be problematic - the OCI deals with SQL data types and not with PL/SQL structures.
The OCI has since Oracle 8i sported an object call interface (see OCI Runtime Environment for Objects for details).
This allows you to use the CREATE TYPE command to create advance user data types - and these are supported by the SQL engine, PL/SQL engine and external languages via the OCI.
So you need to have a look at the Perl-DBI documentation to see how it supports Oracle object types and consider using these. As for internal PL/SQL data structures. These are not supported by the SQL engine and I would expect limited or no support in the OCI for these. Anyway, using SQL data types makes a lot more sense ito flexibility and transparency across languages and environments.

Hi ,
Why do you wantto use templates as table control .
You should use table control in place of template to dipslay contents of an internal table .
To use table control as template put template inside a loop . Im not sure it works or not .

How to convert select-options table into single field internal table

Hi,
My requirement is to convert select-options table into single internal table which has one field.
e.g. select-options: s_matnr for mara-matnr.
       select-options table can have options 'BT',"EQ", "NE", "GE", "GT", "LE", "LT", "CP" etc. select-options table
       have   Sign:I ,Option:BT, Low: 1, High.10.The new internal table records should be 1,2,3,4,5,6,7,8,9,10.
Please suggest any function module available for this scenario in SAP.
Thanks,
Somi.

Hi Sowmya,
Here is the answer if I understand well of your question.
Data: begin of gt_mon OCCURS 0,
              mon(2)             TYPE n,
         end of gt_mon.
Data: begin of gt_year OCCURS 0,
              year(4)             TYPE n,
         end of gt_year.
Select-options: s_period       FOR ptdw_pws_db-kmonth NO-EXTENSION
                                                                                DEFAULT sy-datum(6)
                                                                                TO sy-datum(6).
For example according to above statement period is 201110 is 201201.
Period field does n't exists in SAP for selection. If your selection is on date based on period which is given on the selection-screen then you need to convert the period to date by concatenating ( or using FM to convert )01 at the end of each period . You need to declare one range table for date to select the data from table.
loop at s_period.
gr_date-sign   = s_period-sign.
gr_date-option = s_period-option.
COncatenate s_period-low
                      '01'
into gr_date-high.
COncatenate s_period-high
                       '01'
into gr_date-low
append gr_date.
ENDloop.

How to invoke PL/SQL Table parameter in the query string?

Hello,
I've met a problem invoking PL/SQL Table parameter in the query string, in OWS 3.0.
What I'm going to do is, to invoke a stored procedure to generate a web page using PL/SQL Web Toolkit 2.0, like: "http://.../owa/test_proc".
But there is a IN parameter for this procedure, and it's a PL/SQL Table variable. So I can't invoke the procedure sucessfully just using "http://.../owa/test_proc?v_plsql=i_plsql".
Did someone have met this kind of problem or have the answer to it? Thanks so much for your help.

When using procedures with pl/sql-tables as parameter they should be overloaded, e.g.:
procedure my_procedure (my_var in varchar2)...
and
procedure my_procedure (my_var in owa_util.ident_arr)
the procedure then can be called with:
http://..../my_procedure?my_var=Scott, which invokes the version with the varchar2 parameter, or
http://..../my_procedure?my_var=Scott&my_var=Miller......
which invokes the version with the pl/sql-Table
Another solution might be the use of flexible parameters, passing pairs of parameter_name, parameter_value to your procedure. Your procedure looks like:
procedure my_procedure (name_array IN owa.vc_arr, value_array IN owa.vc_arr)..
and is invoked (note the ! )
http://..../!my_procedure?ename=Scott&sal=200&job=clerk.....
looping through the pl/sql tables will retrieve values of ename, sal and job for name_array and Scott, 200 and clerk for value_array

You are correct - cast the bind as the proper type. I have a SQL type named emp_table_type so this works
explain plan for select * from table(cast (:e1 as emp_table_type))The types involved are
CREATE OR REPLACE TYPE SCOTT.emp_scalar_type as object

How to convert PL/SQL Objects to XMLTYPE and use external schema

We are creating PL/SQL Objects using Jpublisher to set values.
We need to build a SOAP request based on that to call Web Service using utl_DBWS/UTL_HTTP.
l_RequestHeader := OBJ_RequestHeader(l_UserObj,l_SourceDet,
l_ReqHeaderId);
XMLTYPE or CreateXML – both take schema(namespace) argument.
For example
reqhead := XMLType(l_RequestHeader,
'Schema URL');
We need converted XML in following format:-
<proc:RequestHeader>
<id>Id</id>
<source>sr1</source>
<user>
<credentials>pass</credentials>
<userID>user</userID>
</user>
</proc:RequestHeader>
But after running XMLType, we are getting like this.
<OBJ_REQUESTHEADER><USER_><USERID_>user</USERID_>
<CREDENTIALS_>pass</CREDENTIALS_></USER_>
<SOURCE_>sr1</SOURCE_>
<ID_>Id</ID_></OBJ_REQUESTHEADER>
XML tags are as per Oracle PL/SQL Wrapper and they are not matching with the request.
Please let us know what is the problem here and any syntax/method to rectify this problem.

"I have created few non cache tables in TT, to compile PL/SQL objects .
if i make any DML's through PL/SQL(passthrough 1) , it is updationg with TT tables but not Oracle table ."
[T2C]: This is correct and it is what you want to do, right?
what is the way to handle non cahe tables updates through PL/SQL, how can we achive non cahe tables updates in TT ,refresh with oracle ( i.e non cahe table updates need to go to the oracle ).
[T2C]: Sorry, but I am not sure I understand. Were you not able to update the non-cached tables, like you mentioned in the first paragraph? Do you mean that you want the non-cached tables to propagate to Oracle? Would that not be a cache table then?

Hi Vijay,
Here's something to start with, you should be able to complete it.
First, combine your select and update statements:
update vt_mlr
   set aggregator_clli = field1
      ,aggregator_vpi_vci = field_2_n_3
      ,aggregator_slot = field4
      ,aggregator_port = field5
where user4 is not null;Then put these two
C1 := INSTR(vt_mlr_record.user4,' ',1,1);
Field1 := SUBSTR(vt_mlr_record.user4,1,C1-1);into
Field1 := SUBSTR(vt_mlr_record.user4,1,INSTR(vt_mlr_record.user4,' ',1,1) -1);And put it into the update statement, removing reference to record
(I have also removed default values for position and occurrence in instr function):
update vt_mlr
   set aggregator_clli = substr(user4, 1, instr(user4,' ') - 1)
      ,aggregator_vpi_vci = field_2_n_3
      ,aggregator_slot = field4
      ,aggregator_port = field5
where user4 is not null; I think you can do the rest from here ;-)

How to convert this SQL query to PL/SQL

I basically need to create an anonymous block that will display each student's first name, last name and the count of students who scored less on test 1 than the student.
So basically we need to find the count of students who have scored less than that particular student and we do it for all students in the table.
So for this particular query i designed my code in SQL
select g1.gr_fname, g1.gr_lname, count(*)
from grade g1, grade g2
where g1.gr_t1 > g2.gr_t1 and
g1.std_code = g2.std_code
group by g1.gr_fname, g1.gr_lname;
But i am unable to get the logic as to how to execute it in PL/SQL,I am missing something a minor detail to execute the same in PL/SQL
could someone please help me with the logic.
Thanks

Hi welcome to the forum try some thing below

How to convert simple SQL Select statements into Stored Procedures?

Hi,
How can I convert following SELECT statement into a Stored Procedure?
SELECT a.empno, b.deptno
FROM emp a, dept b
WHERE a.deptno=b.deptno;
Thanking in advance.
Wajid

stored procedure is nothing but a named PL/SQL block
so you can do it like this see below example
SQL> create or replace procedure emp_details is
2 cursor c1 is SELECT a.empno, b.deptno
3 FROM scott.emp a, scott.dept b
4 WHERE a.deptno=b.deptno;
5 begin for c2 in c1
6 LOOP
7 dbms_output.put_line('name is '||c2.empno);
8 dbms_output.put_line('deptno is ' ||c2.deptno);
9 END LOOP;
10 END;
11 /
Procedure created.and to call it use like below
SQL> begin
2 emp_details;
3 end;
4 /
PL/SQL procedure successfully completed.
SQL> set serveroutput on;
