How to use PL/SQL in javascript

Hi, Iam trying to do the following:
I need to call a function PL-SQL from javascript. In Oracle I can do this with sth like:
variable result varchar2(100);
exec :result := MyFunction(param1, param2);
(a string with a varible long returns)
Someone could help me and tell me which is the right way to do this in javascript?
Thanks
Veronica Loureda

I don't think you can execute PL/SQL from javascript.

How to Use Dynamic SQL

Can anybody please send me a small program on How to Use Dynamic SQL.
How to execute and run give details.
Thanks

You can certainly use the INTO (and USING) clauses of EXECUTE IMMEDIATE to pass in and return data, i.e.
EXECUTE IMMEDIATE sqlStmt
USING variable1, variable2
INTO output1, output2The more complex the statement, however, the more appropriate DBMS_SQL is. DBMS_SQL also has the potential to allow you to use bind variables rather than reparsing the statement many times.

Hi experts, how to use open sql to read data from one " maintenance view"?

i want to use this part of data within report ,so how to use open sql statement to read data from one " maintenance view"?

Hi
You can't use OPEN SQl statements to fetch data from maintenance view
You have to use only Database views
see the different types of views and the difference
The followings are different types of views:
- Database View (SE11)
Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set.
In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
- Help View ( SE54)
Help views are used to output additional information when the online help system is called.
When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view.
- Projection View
Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.
A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
- Maintenance View ( SE54 )
Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.
Please have a look at below link. It will help you.

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

        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 use count sql statement?

i've never used the count function and i'm not sure how to use it to print it onto a html page...my code is below...
<%
String tot = (String)session.getAttribute("total");
int total = Integer.parseInt(tot);
Class.forName("org.postgresql.Driver");
// create connection url
String URL2 = "jdbc:postgresql://dbhost/ug59sxn";
// pass database parameters to JDBC driver
Connection Conn2 = DriverManager.getConnection(URL2, "ug59sxn", "hupeswop");
// query statement
Statement SQLStatement2 = Conn2.createStatement();
// generate query
String Query2 = "SELECT COUNT(*) FROM userteam WHERE total > '"+total+"'";
// get result code
ResultSet SQLResult2 = SQLStatement2.executeQuery(Query2);
int position = (int)SQLResult2 + 1;
%>
<TD valign=top>
Welcome <%= session.getAttribute("fName") %> <%= session.getAttribute("surname") %> 
Your Team, <%= session.getAttribute("teamname") %>, are currently lying in position <% out.println(position) %>, with <%= session.getAttribute("total") %> points. 

 Use the shorcuts on the left to visit different sections of the game.
You can change your squad around to prepare for forthcoming games (fixtures can be found in the statistics section),
transfer a player in to your squad to add some depth or replace injured members, or perhaps browse the statistics section to see how your team is doing in the FFL table.
<HR>
<%

You cannot cast a ResultSet object (or any other object for that matter) to a primitive (such as an int)
Replace the following line of code:
int position = (int)SQLResult2 + 1;with this:
int position = 0;
if(SQLResult2.next())
position = SQLResult2.getInt(1) + 1;
}Additionally I noticed that you have put single quotes around total in the following line:
String Query2 = "SELECT COUNT(*) FROM userteam WHERE total > '"+total+"'";Are you sure that the total column in the userteam table is of string type? If not, you don't need the single quotes.

How to use Native SQL statement in JDBC receiver interface

Dear All,
Can any one please help us in using Native SQL statement in a JDBC receiver channel. The reason why I need to use Native SQL statement instead of standard XML structure is that I need to execute a dynamic SQL query in third party database system lke:-
Select Field1 Field2 from TABLE Where Field3 like "%Name'
I expect the the response in the form of XML file which I can pick up using synchornous interface as mentioned on help.sap.com:-
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
The value for %Name can change dynamically according to the transaction and hence cannot be inluded as a KEY element in standard XLM structure,
Hence I need to know:-
1. What message mapping I should use in case if I have to use Native SQL statement.
2.What operation mapping I should use in case if I have to use Native SQL statement.
If guess correclty I may have to use Java mapping to do the above activities. Hence I want to know
3 .How do to go about it to do the Java mapping.
Thanks

You can use a stored procedure, and call it from jdbc receiver adapter.
I also solve this issue, with a DBLookup in message mapping. You can refer to my blog, and this usefull 3d:

How to use this sql query in oracle?

Hi all,
i am using one sql query that is
SELECT @ToDate = '2012-10-03 00:00:00.000'
select @BetweenDate = DATEADD(MM,-1,@ToDate)
select @FromDate = DATEADD(m,DATEDIFF(m,0,@BetweenDate),0)
SELECT @ToDate = DATEADD(month, ((YEAR(@BetweenDate) - 1900) * 12) + MONTH(@BetweenDate), -1)
so @todate value is = '2012-10-03 00:00:00.000'
so in @betweendate value will come 1 month before like '2012-09-03 00:00:00.000'
again in @fromdate value will come like that '2012-09-01 00:00:00.000' means first date of @betweendate
and again @todate value will come like that '2012-09-30 00:00:00.000' means last date of @betweendate
it's happening in sql and i have to use same logic in oracle also.
how to use it??
thanks

declare
todate date:= to_date('2012-10-03 00:00:00','yyyy-mm-dd hh:mi:ss');
betwendate date := add_months(todate,-1);
for datediff / additions you can direct subtract/add two different date variables
like
datediff = betweendate -todate
dateadd := todate+1;

How to use Pl/Sql function in Discoverer report

Hi Everybody,
Would you be able to provide a workflow/guidance how to use sql function in Discoverer right from creating the function using PLSQL Developer.
(I am new to Oracle environment... prev. worked as analyst with Microsoft Access... took PL/Sql class in school a few years ago)
We are using Discoverer Desktop.
a) Just emailed dba for permission to create pl/sql function.
b) Recently got Discoverer Administrator installed on my pc.
can you pls add to the list:
c)....
d)....
etc.?
tx for your help, sandra

Hi Kranthi,
Thx for your warm words....
The links you provided are great! Thx soooo much!
Thanks to you and the rest of forum members, am able to use what you've all taught me
with other Discoverer reports.... so i was able to do more on my own....
About a month ago, I got access to Discoverer Admin, and was able to paste SQL to create a custom folder.
Then i joined the custom folder to an existing baseline folder.
I have found that sometimes when I use calc within a calc when the calcs use analytic functions, that Discoverer
just displays null in the column. I thought that maybe instead I could create my own function as a work-around.
I wrote IT for permissions to create views, functions etc. Hopefully, they'll approve and can move toward learning
pl/sql functions for Discoverer.
tx again, sandra

How to use Native SQL String

Hi all,
How do i use Native SQL String in the Reciver JDBC Adapter.
Do i need to change the message format could u suggest me some blogs on the same.
Also please can anyone let me knw if i can use this for stored procedure.

hi aditya,
there shud be no format as such. for sql xml format there are specific structure. but for native sql there shudnt be any specific structure.
as pointed in sap documentaion:
Instead of an XML document format, a text is expected that represents any valid SQL statement.
When inserting a line into a table the corresponding document looks as follows:
INSERT INTO tableName (column-name1, column-name2, column-name3) VALUES(column-value1, column-value2, column-value3)
so jus make sure that u give a valid sql statement becoz if will be passed as it is to the database and try ur scenario.
regards,
latika.

How to use java.sql.Date ?

hi there:
I used
ps.setDate(27, new java.sql.Date(new java.util.Date().getTime()));
ps.executeUpdate();
in my code to insert the current date to the 27th column of one table, this column's type is DATE, the database is ORACLE. However, I got the error like this one: ORA-01843: not a valid month.
I think I incorrectly used the java.sql.Date API to cause this error. So anyone can tell me how to use it correctly?
Thanks for the answers,
Sway

Other columns are all VARCHAR2 type;
The oracle error message indicated that this is a
date-related one. 27th are the only column using DATE
So I came to draw my conclusion that the SQL might be
wrong.Except that if, for example, the date column is actually at index 26 then Oracle might try to convert the string being passed in (at 26) as a date. But it isn't a date. So then oracle is going to throw an exception indicating that something is wrong - like that the month is invalid.

thanks in advice,

Hello Gaurav,
First off, not sure why you are calling
call.addNamedArgument("JOB_ID", "JOB_ID_I");
call.addNamedArgumentValue("JOB_ID", jobId);
You should call the first statement to indicate you will be adding in a "JOB_ID_I" argument to the query, or the second statement to add the value directly to the call, but not both. Calling both indicates your procedure is expecting two parameters called "JOB_ID" and you will get an exception if you do not define the "JOB_ID_I" argument on the query and pass in a parameter for it.
TopLink does not currently create Oracle objects such as Structs and VARRAYs for you from java objects - atleast not for stored procedures arguments, as it does not know how or what to convert them to. You will need to create the Oracle object type yourself, and pass it into the query. I have not tested it, but it would look something like:
UnitOfWork unitOfWork = getUnitOfWork();
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("DSM_JOB_PKG.INSERT_JOB_RUN_LOG");
String jobId = jobIdItr.next().toString();
call.addNamedArgumentValue("JOB_ID_I", jobId);
Timestamp sysdate = BeanConvertUtil.getCurrentTimestamp();
call.addNamedArgumentValue("ORDER_DATE_I", sysdate);
call.addNamedArgumentValue("USER_ID_I", userId);
Connection con = getSession().getAccessor().getConnection();
oracle.sql.ArrayDescriptor anArrayDescriptor = new oracle.sql.ArrayDescriptor("GENERIC_STRING_TYPE",con);
oracle.sql.ARRAY anARRAYin = new ARRAY(anArrayDescriptor, con, paramTypeIds );
call.addNamedArgumentValue("JOB_PARAM_TYPE_IDS_I", anARRAYin );
oracle.sql.ARRAY anARRAYin2 = new ARRAY(anArrayDescriptor, con, paramValues);
call.addNamedArgumentValue("JOB_PARAM_VALUES_I", anARRAYin2 );
session.executeSelectingCall(call);

How to use PL/SQL Function after registering

Hi,
I have successfully registered a PL/SQL Function within Discw Admin. But i don't know how to use it further??? Please let me know the steps to use it in folders (admin) or in plus.
Actually i have a stored procedure which fetches the records from the base tables and i have to develop a report based on that data.
Please reply ASAP.
Thanks,
Jay

Hi Jay,
If this function is a stored procedure in the right schema, you can access this function in your custom SQL like any other database functions (e.g. SUM, AVG, MAX, etc).
If you are not using a custom folder (ie. your own SQL), you can access this function in the workbook (Tools --> Calculations --> New Button --> Select Function Radio Button --> All Functions or Database Folders.). This calculation wil become a new column in the workbook.

John
