How to use Add Query Criteria for the MySQL data Base in Netbeans ?

How to use Add Query Criteria for the MySQL data Base in Netbeans Visual web pack.
When the Query Criteria is add like
SELECT ALL counselors.counselors_id, counselors.first_name, counselors.telephone,counselors.email
FROM counselors WHERE counselors.counselors_id = ?
when i run this Query in the Query Window
i get a error message Box saying
Query Processing Error Parameter metadata not available for the given statement
if i run the Query with out Query Criteria its working fine.

*I am glad I am not the only one who have this problem. Part of issue has been described as above, there are something more in my case.

Also when I tried to update my MYSQL connector / J driver to version 5.1.5 from 5.0.5 (NB 5.5.1) and 5.0.7 (NB 6.1), I could not get it work (looooong time to search some JDBC classes and with no response in the end) on both of my Netbean 5.5.1(on PC) and Netbean 6.1(on laptop) IDEs.
Could anybody look into this issue.
Many thanks

SAP QUERY -logical data base ADA

I have created a SAP Query with logical data base ADA,I have selected four tables in it.Do i need to link these tables if yes..where and how?The report is for fields in asset master data.
.But i get below error when i try to genaret the output :
Fields from parallel tables within a line
Line: 01
Field: Asset description
(ANLT-TXT50, table ANLT)
Field: License plate no. of vehichle
(ANLZ-KFZKZ, table ANLZ)
i get such similar five messages but they are warning..when i execute with warning however i get the fields with description but not with Value.Ex:i get asset description and not Asset number as required.

You don't have to link them, they ar linked that is the power of a logical data base
To get the text in your report you need the key fields
Like
(Lanque Key)
company code
asset number
Asset sub number
Go to info sets and look to the standard ones like /SAPQUERY/AM01

Regarding Data Base Select Query

Hi All,
          I want to extract the data from data base into my internal table
          by not giving the exact value but the pattern.
          Ex) I want to select the vendor starting with patter '12*'
                from LFA table in my internal table.
          Which select Query I should use for getting the
          Vendor No. starting with pattern '12*' ?.
          Points will be rewaded.
          Thanks in Advance.
With Regards
Jitendra Gujarathi.

Hi jitendra,
1. simple
2.
select * from lfa1
into table lfa1
where lifnr like '12%'.

Is there any standard logical data base which gives all the required fields mentioned above? since i am not SD consultant i am not sure whether i have to take only above tables exactly or not
there are certain logical databases like SD_ORDER,SD_SALES_DOCUMENT which has tables VBAK,VBAP,VEDA but i am unable to join remaining tables VBREVE and VBREVK with those logical data bases
Please provide some valuable suggestions on this.
Thanks&Regards

How to delete copyed wrongly in the data base

Hi Gurus,
I copy the cube 0IC_C03 to Z0IC_C03.
After that i went to RSZC--> copy from 0IC_C03 to Z0IC_C03 all the queries, but when i am copying i dint remove the _1 beside each query. when i repeat system telling queries already in the data base. can you tell how to delete and copy freshly.
Points Assure.
Thanks
Amarendra

Hi,
you can use rszdelete where you can choose the queries and query objects which you want to delete.
After this you can start the copy again.

Performance problem in select data from data base

hello all,
could you please suggest me which select statement is good for fetch data form data base if data base contain more than 10 lac records.
i am using SELECT PACKAGE SIZE n statement, but it's taking lot of time .
with best regards
srinivas rathod

Hi Srinivas,
if you have huge data and selecting ,you could decrease little bit time if you use better techniques.
I do not think SELECT PACKAGE SIZE will give good performance
see the below examples :
ABAP Code Samples for Simple Performance Tuning Techniques
1. Query including select and sorting functionality
tables: mara, mast.
    data: begin of itab_new occurs 0,
             matnr like mara-matnr,
             ernam like mara-ernam,
             mtart like mara-mtart,
             matkl like mara-matkl,
             werks like mast-werks,
           aenam like mast-aenam,
stlal like mast-stlal,
     end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on
fmatnr = gmatnr where gstlal = '01' order by fernam.
Code B
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      werks like mast-werks,
      aenam like mast-aenam,
      stlal like mast-stlal,
end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01'.
sort itab_new by ernam.
Both the above codes essentially do the same function, but the execution time for code B is considerably lesser than that of Code A. Reason: The Order by clause associated with a select statement increases the execution time of the statement, so it is profitable to sort the internal table once after selecting the data.
2. Performance Improvement Due to Identical Statements Execution Plan
Consider the below queries and their levels of efficiencies is saving the execution
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      werks like mast-werks,
      aenam like mast-aenam,
      stlal like mast-stlal,
end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01' .
sort itab_new.
select fmatnr fernam
fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as
f inner join mast as g on f~matnr =
gmatnr where gstlal
= '01' .
Code D (Identical Select Statements)
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      werks like mast-werks,
      aenam like mast-aenam,
      stlal like mast-stlal,
end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01' .
sort itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01' .
Both the above codes essentially do the same function, but the execution time for code B is considerably lesser than that of Code A. Reason: Each SQL statement during the process of execution is converted into a series of database operation phases. In the second phase of conversion (Prepare phase) an execution plan is determined for the current SQL statement and it is stored, if in the program any identical select statement is used, then the same execution plan is reused to save time. So retain the structure of the select statement as the same when it is used more than once in the program.
3. Reducing Parse Time Using Aliasing
A statement which does not have a cached execution plan should be parsed before execution; this parsing phase is a highly time and resource consuming, so parsing time for any sql query must include an alias name in it for the following reason.
1.     Providing the alias name will enable the query engine to resolve the tables to which the specified fields belong to.
2.     Providing a short alias name, (a single character alias name) is more efficient that providing a big alias name.
Code E
select jmatnr jernam jmtart jmatkl
gwerks gaenam g~stlal into table itab_new from mara as
j inner join mast as g on jmatnr = gmatnr where
            g~stlal = '01' .
In the above code the alias name used is j .
4. Performance Tuning Using Order by Clause
If in a SQL query you are going to read a particular database record based on some key values mentioned in the select statement, then the read query can be very well optimized by ordering the fields in the same order in which we are going to read them in the read query.
Code F
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      end of itab_new.
select MATNR ERNAM MTART MATKL from mara into table itab_new where
MTART = 'HAWA' ORDER BY MATNR ERNAM MTART MATKL.
read table itab_new with key MATNR = 'PAINT1'   ERNAM = 'RAMANUM'
MTART = 'HAWA'   MATKL = 'OFFICE'.
Code G
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      end of itab_new.
select MATNR ERNAM MTART MATKL from mara into table itab_new where
MTART = 'HAWA' ORDER BY ERNAM MATKL MATNR MTART.
read table itab_new with key MATNR = 'PAINT1'   ERNAM = 'RAMANUM'
MTART = 'HAWA'   MATKL = 'OFFICE'.
In the above code F, the read statement following the select statement is having the order of the keys as MATNR, ERNAM, MTART, MATKL. So it is less time intensive if the internal table is ordered in the same order as that of the keys in the read statement.
5. Performance Tuning Using Binary Search
A very simple but useful method of fine tuning performance of a read statement is using Binary search addition to it. If the internal table consists of more than 20 entries then the traditional linear search method proves to be more time intensive.
Code H
select * from mara into corresponding fields of table intab.
sort intab.
read table intab with key matnr = '11530' binary search.
Code I
select * from mara into corresponding fields of table intab.
sort intab.
read table intab with key matnr = '11530'.
Thanks

How to read a byte data from maxdb data base

Dear All,
I have a issue in reading the data from database table.
I have a column named as templateData which contains the byte data (biometric template data, which comes from fingerprint device) which is DataType of LONG and CODE of BYTE.
I am not using the below to get the template data
Connection con = null;
Statement stmt = null;
ResultSet resultSet = null;
byte[] DbBioData = new byte[1024];
InitialContext ctx = new InitialContext();
   if(ctx == null)
     throw new Exception("Boom - No Context");
   DataSource ds = (DataSource)ctx.lookup(db_drvstr);
   con = ds.getConnection();
   stmt = con.createStatement();
   resultSet = stmt.executeQuery(db_query + " where SUBJECT_ID='"+ username +"'");
   if(resultSet.next())
    DbBioData = resultSet.getBytes(1);
    _loc.infoT("verify", "verify::Got BioData From MAXDB" +DbBioData );
    loc.infoT("verify", "verify::Query is: " +dbquery + " where SUBJECT_ID='"+ username +"'" );
But I am not getting the proper data, could anyone please tell me the way to read the biometric data from data base table.

Hi Kishore,
is it me or is there no query definition in that code?
I see that you concatenate a "db_query" with a string to make up a WHERE clause, but the db_query is nowhere defined before.
So at least you should provide something like
stmt = con.createStatement("SELECT templateDate FROM <tablename> ");
before you do anything with the query.
Besides this: have you ever heard of SQL injections? Try to use BIND-variables instead of concatenating strings. Otherwise your application will spend much time just with parsing your queries...
Hmm... possibly the best thing you could do about this is to read the JAVA manual for MaxDB:
<a href="http://maxdb.sap.com/currentdoc/ef/2de883d47a3840ac4ebb0b65a599e5/content.htm">Java Manual (SAP Library - Interfaces)</a>
Best regards,
Lars

Get data from a Data Base in MySQL

Hi guys,
I'm developing an app for my exam at school. In this app I need to query my Data Base to get my data and to create a table.
The purpose of my app is to create a list of songs that a DJ has played during a concert and automatically create a table with the song titles, artist name and date of the concert. All of these information are already stored in the Data Base.
I created an interface in Xcode where the user types in the DJ name and the date. I want to query the Data Base with these information and create a table that can be view directly on the iPhone. I think that I can send the text contained in the text field to a PHP page and then the PHP page does the query.
Is it possible doing this? Can you help me with the code?
If you need any explanation just ask me.
Thank you very much!

Thanks for the reply, I found the problem, i was returning no.sentDate in the form YYYY-MM-DD and method getTime doesn't like so it was returning null, so what I have done was cast(no.sentDate as datetime) and also store the difference of the dates as a long variable as I need the difference between the dates not the day of the month.
My code now looks like this:
conWorkPartyID = con.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY);
String sWorkOrderID = "select co.orderPartyid, no.workOrderListPartyid, wl.workOrdListDesc, cast(no.sentDate as datetime) as newDate from contractorOrders as co "+
"left join newOrders as no on no.orderPartyid = co.orderPartyid "+
"left join workOrderList as wl on wl.workOrderListPartyID = no.workOrderListPartyid "+
"where co.flagSentToContractor = 0 and co.contractorPartyid =" + sCompany;
cWorkPartyID = conWorkPartyID.executeQuery(sWorkOrderID);
while(cWorkPartyID.next()){
Object x = cWorkPartyID.getObject("co.orderPartyid");
Object y = cWorkPartyID.getObject("no.workOrderListPartyid");
Object z = cWorkPartyID.getObject("wl.workOrdListDesc");
Date dateTest = cWorkPartyID.getDate("newDate");
Date Now = new Date();
System.out.println("dateTest is: " + dateTest.getTime());
long dif = ((Now.getTime() - dateTest.getTime())/86400000);// milliseconds to days
System.out.println("Order PartyID that require your attention is : "+ x + " and workOrderPartyid: " + y +" and WorkOrderListDesc: "
+ z + " and the sent date is: "+ dateTest + "and the difference between the insertDate and the today is in days: "
+ dif);
cWorkPartyID.close();
Any other suggestions are welcome.
Thanks for answering so soon.
Good night!

Help: How to call a user defined function in a data block query?

I created a string aggregation function in the program unit, see reference:
http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php
I now like to call the function in my data block query. I got the error: ORA-00904: 'concatenate_list' invalid identifier.
Please help.
Thank you in advance.

Hi,
You can write UDFs in java in Graphical mapping to enhance your XI Graphical mapping functionality
The steps for doing it would be:
1. Click on Create New function Button found on Bottom left corner on your XI Mapping window.
2. Write your java code.
3. Run the Mapping Test as usual.
>>The module that is given here ...where and how it is used.
The adapters in the Adapter Framework convert XI messages to the protocols of connected external systems and the other way around. When doing so, some
functionality might need to be added specific to a situation which is possible with the use of custom modules.
Typical example would be validation of file content when using a File Adapter or modification of the message payload to a common content structure which is not supported by any of the standard SAP modules.
An Adapter module is developed as an Enterprise Java Bean and is called locally by the Adapter.
An example on modules :

Logical Data Base - ADA

Hi, people,
I`m using Logical Data Base ADA in my program to generate some files, but when the program is executed in DEV System the files are generated normaly, but in the PRD system don´t work.
Someone knows if exist same parameter or why this problem occurs ?
Tks for all.
Flavio

As ADA is a standard logical database, if you don't change this object, there should be no difference, except Authorizations that may differ between development and production systems , check via [SU53|http://www.sdn.sap.com/irj/scn/advancedsearch?query=su53+#sdn_content_category_value_wiki].
(In AM "Asset Accounting" class, check authorization objects : A_A_VIEW, A_S_ANLKL, A_S_GSBER, A_S_WERK.)

When to refresh Servlet data from Data Base

Hello all,
I have a servlet that retrive few hundreds thousands records from data base table.
The data in data base table being updated once or twice in every week.
Since same servlet instance serve all users, that access the servlet many times a day.
I would like to avoid retriving the data from data base on each servlet access.
and make the users use same data already retrieved and kept in servlet members.
First, what is the best way to avoid data retrive from data base on each servlet access?
and how could I have some kind of trigger that will refresh servlet data from data base every few days?
Thanks in advance for every idea.

Thanks Saish for your reply.
I'm not using DAO in my application but retrive the data from BI data base using a web service. response time querying the BI data base is not quick enuogh.
Since, I wouldn't want to query the BI server on each servlet access.
Because the data I retrived at the begining using the web service contains all required data for all servlet requests, I thought to store the data (~200K rows) once in the servlet which will be using for all requests.
Why not store the results locally in your own database after you fetch them?
This still leave me with the questions: in which event should I query the BI data, and also when or in which event should I update the data again from BI server?
Query at startup, an user demand, when data becomes stale. It depends on your requirements.

Pivot Report in Excel from Oracle data base

I need to bring data in Excel from Oracle table.
The connectivity was established without any problem.
When trying to transform the newly created query into
a pivot table a am not able to see the data inside the
"Data area" of pivot table as it is in the data base
tables, instead Excel transforms the data in Sum, Average,
etc...
I believe it is an Excel issue but I am not sure.
Any sugestions would be appreciated.
Thanks,

Hi Shahid,
I am not sure what your question is. The code you pasted looks like the MatrixAndDataSources example that comes with the SDK. What are you trying to do?
Thanks,
