Distinct SQL clause with Recordset object

Hi all, I was using a recordset with an sql distinct clause, on SAP B1 SP:0
Now we have updated to SP1, and it seems like recordset query doesnt works well with the distinct clause.
It returns all values.
Does anybody tried to use this clause with SP1?
Thanks.

Hi,
The DISTINCT clause by itself is NOT working in recordsets. You have to programatically make sure that you have the distinct records. So, if you're adding distinct records to a combo box you can either check if it exists before you add it or you can add a try... catch block around it that just catches the error (without displaying anything) when you add to a combo box.
Hope it helps,
Adele

How to Set Distinct SQL Clause on View Object without using Expert Mode.

Hi to all Actually i have a View Object usign 3 entities
if i use expert mode in my VO, it generate
QRSLT WHERE
instruction and force to include all columns on my dynamic where clause on select statement i can't include columns because get me duplicate rows
How i can include disctinct clause without usign expert mode or any other solution?
Note that in normal mode without expert mode QRSLT WHERE is not generate and all work fine
For example
select * ( select id , name from table) QRSLT WHERE loc = ..
if i use expert mode it generate QRSLT WHERE and if loc is not predicated colums get me and error :
( ORA-00904: invalid identifier )
in simple mode of View Object all work fine..
Any suggestion on It will be appreciate.....
Tnx

My problem is that when use expert mode
it's change simple select statement for a select that use
select * from (select column....)
qrslt WHERE (column=somevalue)
this kind of select force me to include all where conditions of qrslt on my select columns and this get duplicate rows
thats beacuse i need include distinct without use expert mode
Anny Help on this?

Can't use ";" in sql clause with Oracle 8.X

Can't use ";" in sql clause with Oracle 8.X
I can't use ";" at the ending of sql clause in VB program. First this program can use with Oracle 7.3.4 database. But now i need to upgrade DB to Oracle 8.1.7 ,program can't operate. It show error Runtime 40002
and 37000:ODBC driver for oracle/invalid charactor
Thankyou

I've seen a lot of discussion about semicolons in SQL
sent from 3rd party applications. A web search should
bring up the discussions.
Also you might get more response if you ask this question
somewhere else. This is not a VB forum, so you may
not reach relevant people.

Performance problem with recordset object

Hi,
I have a performance problem with record set object. Is it true using RecordSet object as argument to the method will cause any perfomance degradation?
here is my code.
finStmtList = selectFinancialStatements(rs, shortFormat, latestOnly, true);
I changed the code by populating the recordset in the method that called the above statement. previously the population of valueobject is within the select FinancialStatements.
Now the method looks like
finStmtList = selectFinancialStatements(ValueObject, shortFormat, latestOnly, true);
Is this fix will result in any performance gain?

Can any one suggest me that the above RecordSet Object contains large number of records that counts up to 1000 rows and having 30 columns? I tested the application. But the performance varies from time to time.
Is there any other way to fine tune it?

SQL error with LIKE clause in statement

Can anyone explain how an SQL statement with a LIKE clause is executed properly?
Seems like it ought to be cut and dried, no pun intended!
When I run the following and set the requestor name = ?, and correctly type in the entire name, a result set (albeit abbreviated) will return.
But if I try to set the request param to LIKE I get an error of some kind, either invalid cursor state or NullPointer exception.
Here's my code.
Statement selstmt = connection.createStatement();
String preparedQuery = "SELECT DISTINCT AID, ACTIVE, REQUESTOR_NAME,REQUESTOR_EMAIL" +
" FROM CHANGE_CONTROL_USER, CHANGE_CONTROL_ADMIN " +
" WHERE REQUESTOR_NAME LIKE '%?%';";
String reqName = request.getParameter("requestor_name");
PreparedStatement prepstmt = connection.prepareStatement(preparedQuery);
prepstmt.setString(1, reqName);
ResultSet rslts = prepstmt.executeQuery();
rslts.next();
int aidn = rslts.getInt(1);
int actbox = rslts.getInt(2);
String reqname = rslts.getString(3);
String reqemails = rslts.getString(4);It's also returning only 1 record for some reason, as I have the following:
<% while (rslts.next()) { %>
<tr class="style17">
 <td><%=reqname%></td>
<td><%=reqemails%></td>
 <td><%=actbox %></td>
 <td><%=aidn %></td>
</tr>
<%
rslts.close();
selstmt.close();
%>If I use
" FROM CHANGE_CONTROL_USER, CHANGE_CONTROL_ADMIN " +
" WHERE REQUESTOR_NAME = ?;";it will actually spit out the name and corresponding email properly, albeit just one record like I said.
Is there some kind of escape sequence I should be using that I'm not?
And why just the one record?
Any help or direction is appreciated!
Thanks.

I have working code for LIKE in PreparedStatement, and its equivalent in your case is something like this:Statement selstmt = connection.createStatement();
String preparedQuery = "SELECT DISTINCT AID, ACTIVE, REQUESTOR_NAME,REQUESTOR_EMAIL" +
" FROM CHANGE_CONTROL_USER, CHANGE_CONTROL_ADMIN " +
" WHERE REQUESTOR_NAME LIKE ?";
String reqName = request.getParameter("requestor_name");
PreparedStatement prepstmt = connection.prepareStatement(preparedQuery);
prepstmt.setString(1, "%" + reqName.trim() + "%");
ResultSet rslts = prepstmt.executeQuery();
rslts.next();
int aidn = rslts.getInt(1);
int actbox = rslts.getInt(2);
String reqname = rslts.getString(3);
String reqemails = rslts.getString(4);

SQL IN clause with Bind parameter?

Hi
I have a simple task that hasn't been so simple to figure out. I want to allow a user to search for one or more comma-separated values in a simple JClient ADF app. Is there a way to use a SQL IN clause with a single bind variable? e.g. SELECT TITLE FROM CITATION WHERE ID IN (:0)
When I pass a single value it works fine but a comma separated list doesn't.
Thanks
John

Update: I wanted to combine the techniques found in two of Steve Muench's articles -
1) Providing Default Values for View Object Bind Variables (so I could display an ADF-bound JPanel with defaults)
http://radio.weblogs.com/0118231/stories/2004/10/07/providingDefaultValuesForViewObjectBindVariables.html
2) Array of String Domain Example (so a user could enter one or more comma-separated values into a text box for DB searches)
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
I learned some helpful stuff about the framework but spent lots of time banging my head against the wall because the two examples wouldn't work when directly combined. To best understand this, be sure to study Steve's examples above.
In example 1 Steve passes an array of objects (Object[] DEFAULT_VALUES) to the ViewObject's where clause using the setWhereClauseParams(Object[] values). However, in example 2 he creates an Oracle Array which contains an Oracle ArrayDescriptor, Connection, and array of values to pass to the "IN" bind variable. Also, example 1 allows for multiple bind vars to be included whereas example 2 allows for an array of data to be passed to a single bind var. Even though my code provides an array to a single bind var (per ex. 2) it should still allow for the passage of multiple bind vars with minimal code modification.
Code from Steve's example 1 was copied into my EmpView ViewObject but certain modifications were necessary:
1) Change the ViewObject's DEFAULT_VALUES from Object[] to String[].
2) Modify the executeQueryForCollection() method in the ViewObject to call a function which will set the bind variables as Oracle Arrays (effectively converting the "params" data type from that of String[] to Oracle Array[])
3) Create a setManagerID(String[]) method in the EmpView object and expose it to the client.
(there are a number of others so it's best for you to go through the code and compare)
I finally got it working so I'm attaching the code, however beware - I'm new to this so there may be other, better ways to go about it. Also, there are no framework bind vars so that section of code is never executed...it compiles but may fail at run time.
In order for this to work I suggest you use JDev to re-create the EmpView and Panel1 objects. This will ensure that the necessary ADF framework components are generated. Once complete, then copy in the code provided.

How to Use SQL Query having IN Clause With DB Adapter

Hi,
I am using 11.1.1.5 want to find out how to Use SQL Query having IN Clause With DB Adapter. I want to pass the IN values dynamically. Any ideas.
Thanks

invoke a stored procedure, it's safer than trying to put together an arbitrary SQL statement in the JCA adapter

SQL IN clause with a Tool variable

We are using using Forte 3.M.2 (just upgraded from 3.G, finally).
Platform is AIX 4.3. Database is DB2 (UDB) (version 5.2 i think).
True, I haven't tried my code on any other platform. I think it should work on NT, because one of our other teams members has set up an NT laptop for portable demos. And it has DB2 (NT version i guess) loaded on it.
Dynamic sql is not really that bad, if you have to go that route to build your list.
Let me know how it goes.

Daniel González de Lucas <danieleam.es> 07/28/00 04:06AM >>>We are getinng some trouble, the DB Manager seems to try to convert
:OfficeList to a unique integer lets say:
:OfficeList value is 3,4,7
so the IN clause
trying with Oracle 8.1.5 converts 3,4,7 in a unique integer (a extrange
value because doesn't match with 3,4 nor 7).
trying with SQL Server 6.5 gives an error converting 3,4,7 to a unique
tinyint.
The idea is that with your sintax the DB Manager must split the TextData
into 3 integer values. I think that it works fine in some DB Managers and
not in others.
Which release and vendor of DB Manager you use?
Which Forté release?
Thank you very much in advance.
Daniel.

I needed to have an "IN" clause for some numbers. Here's how I did it:
GetOffices():TextData method...
Offices : TextData = new ;
for (x : integer) in sql select MyIntegerColumn
from MY_TABLE
where whatever condition
on session MyDBSession do
Offices.Concat(x) ;
Offices.Concat(',') ;
end for ;
return (Offices.CopyRange(0,Offices.ActualSize -1)) ; // get rid of lastcomma
in actual sql.....
OfficeList : TextData ;
OfficeList = GetOffices() ;
sql select * from MyTable where MyField in (:OfficeList)
on session MyDBSession ;
Works very well.

SQL statement with union clause

Hi,
I have a scenario where i need to generate a sql statement with UNION .
Eg:
SELECT B.YY_ID,
FROM XXXX.YY B
WHERE (B.YY_TY= 'as')
UNION
SELECT B.YY_ID
FROM XXXX.YY_ALT_NAME A, XXXX.YY B
WHERE (A.YY_TY= 'zx'
AND (B.YY_ID=A.YY_ID)"
I tried ns1:table1() union ns3:table2() in XQuery.
But it is pushdown as 2 seperate sqls.
Is it possible to create XQuery that pushdown as SINGLE SQL statement with union clause ?
Thanks

No. See 3.1.1.5 in the document I referenced in your previous post.

Hosting company does not support SQL query with OUTFILE clause

From my mysql database, I want to allow the user to run a query and produce a csv / text file of our membership database. Unfortunately, I just found out my hosting company does not support the SQL query with OUTFILE clause for MySQL database.
Are there any other options available to produce a file besides me running the query in phpadmin and making the file available to users.
Thanks. George

Maybe this external Export Mysql data to CSV - PHP tutorial will be of help

Can you see what's wrong with my sql clause?

Select afkogltri sum( afpowemng ) as yqty
 from ( afpo inner join afko on afpoaufnr = afkoaufnr )
 into ( d_gltri , d_wemng )
 where afpo~matnr = wa_pir-matnr
 and year( afko~gltri ) = year( sy-datum )
 group by afko~gltri.
The above is my sql clause, when I do a syntax check, it said:"Comma without preceding colon (after SELECT ?)"
Can you tell me what's wrong with this sql clause?
Thank you very much!

Hi,
Select Bgltri sum( Awemng ) as yqty (????)

from afpo as A inner join afko as B
on Aaufnr = Baufnr
where A~matnr = wa_pir-matnr
and year( B~gltri ) = year( sy-datum )
group by B~gltri.
ENDSELECT.
eg:... INTO (f1, ..., fn)
Places the result set in the target area (f1, ..., fn). The fields of the result set are transported to the target fields fi from left to right. INTO (f1, ..., fn) is allowed only if a list with n elements is also specified in the SELECT clause.
If the result of a selection is a table, the data is retrieved in a processing loop introduced by SELECT and concluded by ENDSELECT. The processing passes through the loop once for each line read. If the result is a single record, the closing ENDSELECT is omitted.
Example
Output a list of all airlines (with short description and name):
TABLES SCARR.
DATA: CARRID LIKE SCARR-CARRID,
 CARRNAME LIKE SCARR-CARRNAME,
SELECT CARRID CARRNAME
 INTO (CARRID, CARRNAME)
 FROM SCARR.
WRITE: / CARRID, CARRNAME.
ENDSELECT

Oracle 8i array DML operations with LOB objects

Hi all,
I have a question about Oracle 8i array DML operations with LOB objects, both CLOB and BLOB. With the following statement in mind:
INSERT INTO TABLEX (COL1, COL2) VALUES (:1, :2)
where COL1 is a NUMBER and COL2 is a BLOB, I want to use OCIs array DML functionality to insert multiple records with a single statement execution. I have allocated an array of LOB locators, initialized them with OCIDescriptorAlloc(), and bound them to COL2 where mode is set to OCI_DATA_AT_EXEC and dty (IN) is set to SQLT_BLOB. It is after this where I am getting confused.
To send the LOB data, I have tried using the user-defined callback method, registering the callback function via OCIBindDynamic(). I initialize icbfps arguments as I would if I were dealing with RAW/LONG RAW data. When execution passes from the callback function, I encounter a memory exception within an Oracle dll. Where dvoid **indpp equals 0 and the object is of type RAW/LONG RAW, the function works fine. Is this not a valid methodology for CLOB/BLOB objects?
Next, I tried performing piecewise INSERTs using OCIStmtGetPieceInfo() and OCIStmtSetPieceInfo(). When using this method, I use OCILobWrite() along with a user-defined callback designed for LOBs to send LOB data to the database. Here everything works fine until I exit the user-defined LOB write callback function where an OCI_INVALID_HANDLE error is encountered. I understand that both OCILobWrite() and OCIStmtExecute() return OCI_NEED_DATA. And it does seem to me that the two statements work separately rather than in conjunction with each other. So I rather doubt this is the proper methodology.
As you can see, the correct method has evaded me. I have looked through the OCI LOB samples, but have not found any code that helps answer my question. Oracles OCI documentation has not been of much help either. So if anyone could offer some insight I would greatly appreciate it.

Before 9i, you will have to first insert empty locators using EMPTY_CLOB() inlined in the SQL and using RETURNING clause to return the locator. Then use OCILobWrite to write to the locators in a streamed fashion.
From 9i, you can actually bind a long buffer to each lob position without first inserting an empty locator, retrieving it and then writing to it.

SEQUENCE Select within an SQL Query with an ORDER BY statement

Does anyone know why you cannot use an ORDER BY statement within an SQL query when also selecting from a SEQUENCE? My query was selecting production data as a result of a filtered search. I want to take the results of the filtered search and create a transaction. I have a sequence for generating transaction numbers where I select NEXTVAL. Since I could possibly obtain multiple, yet distinct, rows based upon my search criteria, I wanted to use an ORDER BY statement to simplify and order the resulting row(s).
I was able to get the SQL select with SEQUENCE.NEXTVAL to work without the ORDER BY, so I know that my SQL is correct. Thanks in-advance.

Okay,
I understand. You want the sequence assigned first and the you want to ORDER BY. You
can do this using pipelined functions. See here:
CREATE OR REPLACE TYPE emp_rec_seq AS OBJECT (
   seq     NUMBER,
   ename   VARCHAR2 (20),
   job     VARCHAR2 (20),
   sal     NUMBER
CREATE OR REPLACE TYPE emp_tab_seq AS TABLE OF emp_rec_seq;
CREATE OR REPLACE FUNCTION get_emp_with_sequence
   RETURN emp_tab_seq PIPELINED
IS
   my_record   emp_rec_seq := emp_rec_seq (NULL, NULL, NULL, NULL);
BEGIN
   FOR c IN (SELECT dummy.NEXTVAL seq, ename, job, sal
               FROM emp)
   LOOP
      my_record.seq := c.seq;
      my_record.ename := c.ename;
      my_record.job := c.job;
      my_record.sal := c.sal;
      PIPE ROW (my_record);
   END LOOP;
   RETURN;
END get_emp_with_sequence;after that, you can do a select like this:
SELECT seq, ename, job, sal
FROM TABLE (get_emp_with_sequence)
order by enamewhich will get you this:
       SEQ ENAME                JOB                         SAL
