SQL query from toplink expression

Hi,
I have a oracle.toplink.expressions.Expression object with me which has been created using oracle.toplink.expressions.ExpressionBuilder. I want to find its equivalent SQL query(say select emp.empname,emp.empId from employee emp) which will be fired in order to fetch data i.e. find its equivalent Statement/PreparedStatement or anything which will help me obtain the raw SQL statement about to be fired.
Please let me know if there is any soln.
Thanks,
Adithya.

You can create ReadAllQuery with the expression and get the query's SQL using query.prepareCall() and then query.getSQLString().

Hi,
Depends on datasource type but you could have a look at ODBC trace or if you have access to the SQL Server you could use profiler to monitor the session.

Retrieve SQL Query from report without RAS.

We have a fat client application which uses Crystal Reports. We upgraded from the RDC/ActiveX viewer to the .Net SDK/.Net Viewer. One feature that we miss is that we used to read the SQL Query that a report used and wrote it to our log file. This helped with debugging and with troubleshooting problems in the field.
Since we only deploy the freely distributable Crystal Reports model and I don't think that RAS falls into this category is there a way which we can read the SQL Query from a report? If not, could you add this to a list of requested features for future versions.
I understand why you removed the ability to set the SQL query, but simply reading it does add value. Maybe it is difficult for you to return this before the report is run in which case giving us the ability to read the value after the report has been run would also be fine.
Alternatively some sort of event that is fired each time a query is executed would also be helpful as this would allow Crystal Reports clients to monitor SQL from sub-reports. You could even build a robust logging mechanism which could report additional information (i.e. number of rows returned, formula evaluations, or anything related to report execution). All of this would make troubleshooting report issues easier for those of us who use Crystal Reports.

Need to know what version of CR you are using?
You can use InProc RAS, it comes with CR and is distributed with the runtime files.
If you are using CR Basic or the version that comes with Visual Studio .NET then no this will not be added to that product line. It is basic functionality only. You will need to upgrade to a Developer version of Crystal reports to take advantage of the the RCAPI features as well as more general API's.
There is logging for our DB drivers but the log files get very large. If you use ODBC then you have the option to turn on tracing also. Using RAS you don't need to turn on logging as you can get the SQL. This won't be added either.
Thank you

How do I call pl/sql function from Toplink

I can easily call a stored procedure from Toplink
====================================================
public Collection executeSelectingStoredProcedure(StoredProcedureCall storedProcedureCall) throws DAOException
Collection returnValue = null;
Session session = null;
session = this.getSession();
returnValue = session.executeSelectingCall(storedProcedureCall);
session.release();
return returnValue;
====================================================
The same does not work for pl/sql functions. Doesnt Toplink treat function calls as a callable statement as in JDBC?
"select <function_name>(<arguments>) from dual" seems to be a work around. If this or using expressions is the only solution can someone please tell me the reasoning behind this shift.
Regards
Aamir Dehlavi

I have the same problem.
I have a PL/SQL function that returns a number. This function receives 2 parameters. I use StoredProcedureCall plus ValueReadQuery.
Session aSession = SessionManager.getManager().getDefaultSession();
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("CIO_UTILS.COUNT_USER_ROLES_IN_MODULE");
call.addNamedArgument("p_persid");
call.addNamedArgument("p_module");
call.addUnamedOutputArgument("rolesnum", Integer.class);
ValueReadQuery query = new ValueReadQuery();
//query.bindAllParameters();
query.setCall(call);
query.addArgument("p_persid");
query.addArgument("p_module");
Vector parameters = new Vector();
parameters.addElement(persid);
parameters.addElement(theModule);
Integer rolesnum = (Integer) aSession.executeQuery(query,parameters);
aSession.release();
if(rolesnum.intValue()<=0)return false; else return true;
However, I receive the following error:
Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: ORA-06550: line 1, column 96:

Error Code: 6550
Call:BEGIN CIO_UTILS.COUNT_USER_ROLES_IN_MODULE(p_persid=>'SANCRA2791', p_module=>'PSL_MONITORING', ?); END;
bind => [=> rolesnum]
If comment the line
"call.addUnamedOutputArgument("rolesnum", Integer.class);"
Toplink is trating it as a procedure, and I also receive an error from PL/SQL.
There should have to be a way of make it to receive the resoult somehow, but I do not know what.
Thanks in advance.

Help in Forming sql query in Toplink...

Hi,
I've the following query in SQL which I need to formulate the same using Toplink expression builder.
SELECT AVG(HPE),AVG(DK), AVG(HDS), AVG(NAS), AVG(EMC), AVG(EBR), AVG(ARC), AVG(CEL)
FROM V_SRTS_AGGREGATE WHERE DATACENTER_ID = 2 AND (UPPER(DATA_FLAG_365) = 'YES') and input_date between sysdate -365 and SYSDATE;
And I've the following in my DAO for Toplink.
UnitOfWork unitOfWork = getUnitOfWork();
     ExpressionBuilder aSrtsAggregateView = new ExpressionBuilder();
     ReportQuery query = new ReportQuery(aSrtsAggregateView);
     query.setReferenceClass( SrtsAggregateView.class );
     query.addAverage("EVA", aSrtsAggregateView.get("hpe"));
     query.addAverage("DK", aSrtsAggregateView.get("dk"));
     query.addAverage("HDS", aSrtsAggregateView.get("hds"));
     query.addAverage("NAS", aSrtsAggregateView.get("nas"));
     query.addAverage("EMC", aSrtsAggregateView.get("emc"));

          Expression dateToLink = aSrtsAggregateView.get("inputDate").between(fromdateLink, todateLink);
          Expression flagToLink = aSrtsAggregateView.get("data_flag_365").equalsIgnoreCase("yes");
          query.setSelectionCriteria(locToLink.and(flagToLink).and(dateToLink));
I'm getting following error

Please advise if any one has suggestions..
Thanks,

The TopLink expression method currentDate() should return the SYSDATE. You could also use ExpressionMath to subtract 365 from this. There is also an expression method literal() that is sometimes useful for advanced SQL.
<p>
i.e.
<code source="java">
Expression dateToLink = aSrtsAggregateView.get("inputDate").between(ExpressionMath.subtract(aSrtsAggregateView.currentDate(), new Integer(365)), aSrtsAggregateView.currentDate());

How to SQL intersect using Toplink expressions

I try to do this SQL intersect
SELECT part_k FROM ATTR_VALUE
where commodity_n ='dab badge' and attribute_n='Badge Width' and attribute_value_x='10'
INTERSECT
SELECT part_k FROM ATTR_VALUE
where commodity_n='dab badge' and attribute_n='Brand Logo' and attribute_value_x='Jaguar'
using the following Toplink expressions:
Expression e1 = builder.get("commodity").equal("dab badge")
.and(builder.get("attribute").equal("Badge Width"))
.and(builder.get("value").equal("10"));
Expression e2 = builder.get("commodity").equal("dab badge")
.and(builder.get("attribute").equal("Brand Logo"))
.and(builder.get("value").equal("Jagua"));
Expression myExpression = e1.and(e2);
However, this would not give me the correct result.
Any suggestions would be greatly appreicated.

Right, TopLink doesn't have an Intersect operator. If it did, you might still get the same problem unless you are using a report query to return only the "part_k" value instead of an object since attribute_n cannot have a value of both 'Badge Width' and 'Brand Logo' at the same time.
You can get the part_k values or the objects from the ATTR_VALUE
table by using a report query for the second expression as a subquery to the IN clause. Something like
ReportQuery subquery = new ReportQuery(yourclass.class);
ExpressionBuilder subBuilder = subquery.getBuilder();
Expression e2 = subBuilder.get("commodity").equal("dab badge").and(subBuilder.get("attribute").equal("Brand Logo")).and(subBuilder.get("value").equal("Jagua"));
subquery.setSelectionCriteria(e2);
subquery.addAttribute("partk");
Expression myExpression = e1.and( builder.get("partk").in(subquery) );Regards,

How to run a sql query from a button in apex 3.0

Hi,
I am brand new and went through/installed the obe project tracker. I have need to create a simple application that displays a result (2 fields, name and license number) based on two parameters (dob and login id) which all are stored in 1 table in the database. I could this very simply in VB or VB.net but have no idea how to do it in apex.
Please provide guidance,
Thank you,
Tom

Hi Tom,
Sounds like a report region will satisfy your requirements.
Create a new report region on one of your pages.
Choose SQL Report and give the region a title.
When you get to the "Enter SQL Query or PL/SQL function returning a SQL Query:" step, type:
SELECT name, license_number
FROM <insert_your_table_name_here>
WHERE dob = :P<n>_dob
AND login_id = :P<n>loginid(replace <n> with the page number that the region is on and use your own table name).
Don't try to run the page yet - it will give 'No data found'
Now, go back to the Page Definition screen and add two items in the region you just created - call them P<n>dob and P<n>login_id
Then, create a button in the same region (to be displayed amongst the region's items) - call it P<n>_GO and click 'Create' (take all the other defaults).
Now you can run the page, put some values into the fields and click go.
If you want to get fancier, you can change the text items to select lists etc. - let us know if you need help with that.
Hope this helps,
Bryan.

Oracle SQL Query from EXCEL 2007 with prompt

Hello,
I have many excel reports where I am pulling information from our Oracle 9 db through Excel using the following method:
http://blog.mclaughlinsoftware.com/microsoft-excel/how-to-query-oracle-from-excel-2007/
http://blog.mclaughlinsoftware.com/2009/11/30/sql-query-in-excel-2007/
However, I am having trouble when I try the following query due to the prompt:
SELECT
IM.ITEM_GROUP,
IM.ITEM,
IM.DESCRIPTION
FROM
LAWSON.ITEMMAST IM
WHERE
IM.ITEM = '&ITEM';
Does any one know how I can connect a prompt to an excel cell and then pass the query on to Oracle, or have a PL SQL prompt work from Excel?
Thanks,
Ben

The 'prompt' as you call it is a sqlplus feature, so does not belong to the SQL language
You would need to write a stored procedure returning a resultset.
create or replace procedure foo(rc in out sys_refcursor, p_item) as
begin
open rc for
'SELECT
IM.ITEM_GROUP,
IM.ITEM,
IM.DESCRIPTION
FROM
LAWSON.ITEMMAST IM
WHERE
IM.ITEM = '||p_item;
end;
and call that using ODBC or asp.net
Obviously this is profusely documented.

Export SQL query from link or button

I want to list several 'canned' SQL queries on one page as buttons or links; and have the result of selection be an immediate extract/download to excel of the data.
How can I best do this?
I suppose I could create separate hidden regions with their own reports that could somehow be referenced in the link. I would like to avoid doing all that, if I can create a package or process that includes the SQL query and that can be called in the link.
Thanks in advance,
Rich
Edit:
Found 'Report Query' functionality in Apex v3.2.1: However I am unable to get this to work; tells me my printer is not set up. I don't want to print the detail, I want it to be downloaded into excel... I don't have a printer configured - & don't want to. The URL provided for download as attachment is:
f?p=&APP_ID.:0:&SESSION.:PRINT_REPORT=reportname
I also have no page 0.
Help?

Sql query from Oracle/Hyperion

Hi, guys. my problem is:
My work environment is windows 2003 server sp2 on both servers, to have a Hyperion System 9.2 and the other Hyperion System 9.3.1. I have an Oracle ODBC server to fetch data.
When you load data from an Oracle database (version 9.2.0.5) to an Essbase cube through a rule file sql Hyperion System with version 9.2 everything works fine, I am all the necessary information. But when I try to do the same (in another server, version 9.3.1 Hyperion System) with the sql query does not do well. What is the problem. the bag is a bad version or set the ODBC
please help me
Thank you very much.
Alberto.

without knowing more information, I'm going to guess the probem is with the ODBC driver. Try using the SQL in a tool like toad to use the ODBC to query the data. That will tell you if it is an ODBC issue or not.

It is possible to execute a SQL query from OMBPlus?

We have some simple SQL scripts we'd like to be able to incorporate into our existing TCL scripts, instead of having to run them outside of OMBPlus in sqlplus. Is is possible to run a SQL SELECT query from OMBPlus and/or TCL? And get a result set back to iterate through?
Thanks,
Jim C.

You can execute SQLPlus from OMB or just get down and use JDBC to execute the SQL, see others posts on forum such as below;

Passing variables to SQL query from checkboxes

Hello,
I have a cursor which gets different ids from an id table. The cursor is something like this:
CURSOR id IS
         SELECT distinct id_ FROM I
                  order by id_;I then iterated through the cursor to made checkboxes to choose multiple ids:
FOR i IN id
       LOOP
        htp.p('<tr>
       <DIV align="left"><td><input type="checkbox" name="option" value=ID '||i.id_||'> </td></tr>');
         htp.p('<font size="'||3||'">'
         ID'||i.id_||'</a></font>'
         ||'</a>' );
       htp.br;
       END LOOP;The values of the checkboxes were extracted by:
var ids ="";
for (var j = 0;j < document.form.option.length; j++)
             if (document.form.option[j].checked)
                 ids = ids + document.lf.option1[j].value + "\n";
        }I have the following SQL query:
Select * from Persons where Identification = ...; I would like to use to pass the values of the checkboxes (i.e. the variable ids ) to my SQL query. I want the user to select multiple values for the checkboxes. For example, they can select 4 and 3. I want to pass the difference to my SQL query....that is, I want the id to be 1. So, I want this:
Select * from Persons where Identification = 1; Any ideas how to do this? Also my code above is in different procedures within a single package.

Your requirement is not very clear. What happens when you select 3 checkboxes? What will be the difference between them? How do you pass that information to the oracle report?
