2.Copy the same RFC to Target(From Where you want to get data)
3.Create a RFC destination(SM59.) in Source
Enter the connection type as 3 and enter the target host and system number ( may be 00)
4.Create a program to calling RFC in Source.
PARAMETERS: p_matnr LIKE mara-matnr.

How to transport the DATABASE TABLE into the Test system ?

Hi Experts,
I am working on BI7, I had created Database table in BDV system using SE11. Tech_name is ZGLACC_TEMP. I had activated it. I had used this database table for the purpose of writing the start routine in the transformation. while I am transporting the transformations to the test system, It is showing as syntax error in ABAP program,
In BDV system there are no syntax errors. it is working fine,
So now I have to transport the database table to test system so that I can transport the transformations into Test system without any error.
Kindly anyone can give the answer , it will be appreciate and points will be assigned.
thanks
sekhar

Hi Sekhar,
Go to SE11, go into the change mode of your table and change the Object Directory entry (Goto -> Object Directory Entry) to some valid package (other than $tmp). Then it will ask for a transport request. Give a transport request and then I believe you know what to do with that transport.
Another thing to keep in mind ... transport all the data elements and domains you have created for this table. Change their Object Directory Entry and assign them to the same transport request.
Best regards,
Kazmi

How to link Azure database tables and fields to VS2012 C++ entry form

We are using Visual Studio 2012 C++ and have successfully connected to the database on Azure, but do no know how to associate the database tables and fields with the C++ application data entry forms. Can anyone help? Thanks

Hello Roxanne,
You could use Entity framework to map classes to Azure tables. Please refer http://www.codeproject.com/Articles/363040/An-Introduction-to-Entity-Framework-for-Absolute-B to

Hi,
Thanks for your response. It is PM related. When I run a T Code - IK18, the field Total Counter Reading field appears. I am looking for that particular fields actual table name and field name. I think I have found it in IMGR table. Now I want to get IMRG-READG in my report, but there is no common fields in neither MKPF or MSEG table. So what can I do to connect IMRG table with either of them ?

How can I create WA element?

Cemil,
Set up a SAP JCo Interface action block. Use the RFC name RFC_READ_TABLE.
In the link editor map the table to "MARA", set RowCount to something small (20 is good sample size) and create an xml transaction property named FIELDS and copy the following into it:
<?xml version="1.0" encoding="UTF-8"?><FIELDS>
      <item>
        <FIELDNAME>MATNR</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>MTART</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>BSTME</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>XCHPF</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>DATAB</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
    </FIELDS>
Then link the Transaction.FIELDS to SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/TABLES/FIELDS}. You may run into problems with two other fields and optionally they can be removed (set link type to remove xml). I usually remove them initially for testing. The two fields are:
SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/NO_DATA}
SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/DELIMITER} (or you can set this to something like a semicolon,";" or tilda,"~". I find it easier to caclulate position by length, but that is my own idiosyncrasy.)
Once you get this one working, we can explore how to do filtering on the dataset. Your output should be something like this:
<?xml version="1.0" encoding="utf-8"?>
<RFC_READ_TABLE>
<INPUT>
    <DELIMITER />
    <NO_DATA />
    <QUERY_TABLE>MARA</QUERY_TABLE>

Add a repeater sourced on:
SAP_JCo_Interface_0.Response{/RFC_READ_TABLE/TABLES/DATA/item}
Link your repeater output to a tracer with this:
Repeater_0.Output{/item/WA}
What you will see in each tracer message is a single line of data with all the fields contents concatenated together. You can look up what each field in the string represents by the length of the field as returned in the Response segment of the RFC_READ_TABLE rfc. Then you can parse out the data you are interested in.
Give this a try and let me know how you succeeded.
By the way, I could not find the scenario you referred to. Can you post a link?

Mike

PL/SQL block query error when going to a remote system with 1 parameter.

Hi,
I am getting the error:
Invalid function body condition: ORA-01460: unimplemented or unreasonable conversion requested ORA-02063: preceding line from HANSEN_REMOTE
The issue appears to result from opening a cursor that is a select statement is in some way accessing records via a dblink and the 'where' clause is has more then one session parameter in it. Here is the smallest pl/sql block that results with an error:
DECLARE
CURSOR c_GetPay IS
SELECT PERSON_ID
FROM CASH_PERSON@HANSEN_REMOTE
WHERE LAST_NAME = :P320_HANSEN_LAST_NAME
AND FIRST_NAME = :P320_HANSEN_FIRST_NAME;
BEGIN
OPEN c_GetPay ;
CLOSE c_GetPay ;
RETURN TRUE;
END ;
If I remove 'AND FIRST_NAME = :P320_HANSEN_FIRST_NAME' from the curser, there is no problem. This block of pl/sql is in a On Load: Before Header
on a page branch. This issue remains consistent in our 1.6.1.00.02 instance of HTMLDB with an Oracle database version 10.1.0.3.0. This instance is
a fresh install of the 10g and HTMLDB.
Does any one have any ideas of why I am getting this error message. I really need to get it resolve soon as we are trying to get an application up by the end of August and there is still alot of coding needing to be done.
Thanks for the help.
Lanie

Scott, I have tried everything that this point except copy the whole table from the remote system.
Here is a short version of what I have tried...
-- hard coded condition...timing was not an issue here...it was quick.
declare
v_in_PersonId number(9);
cursor c_GetPay
IS select PERSON_ID --, first_name, LAST_NAME
     from HANSEN_CONTACT
          where first_name like 'LANIE'
          AND last_name LIKE 'MOORE'
BEGIN
OPEN c_GetPay;
FETCH c_GetPay INTO v_in_PersonId;
CLOSE c_GetPay;
RETURN TRUE;
END
-- this is an internal variable set to the string literal...does not as the v function was not called.
declare
V_TEST VARCHAR2(150);
V_TEST2 VARCHAR2(150);
v_in_PersonId number(9);
cursor c_GetPay
IS select PERSON_ID --, first_name, LAST_NAME
     from HANSEN_CONTACT
          where first_name like :V_TEST
          AND last_name LIKE :V_TEST2
BEGIN
V_TEST := 'LANIE';
V_TEST2 := 'MOORE';
OPEN c_GetPay;
FETCH c_GetPay INTO v_in_PersonId;
CLOSE c_GetPay;
RETURN TRUE;
END
-- this has the v function called in the cursor since no matter what I do, I have to call it so I don't get my original error. This takes over a minute to return, and it is using hard coded values...if I use session variables where I place the information from the user, it takes even longer.
declare
V_TEST VARCHAR2(150);
V_TEST2 VARCHAR2(150);
v_in_PersonId number(9);
cursor c_GetPay
IS select PERSON_ID --, first_name, LAST_NAME
     from HANSEN_CONTACT
          where first_name like V(:V_TEST)
          AND last_name LIKE V(:V_TEST2)
BEGIN
V_TEST := 'LANIE';
V_TEST2 := 'MOORE';
OPEN c_GetPay;
FETCH c_GetPay INTO v_in_PersonId;
CLOSE c_GetPay;
RETURN TRUE;
END
It does not appear to be an issue if I am looking at a view going to the remote system or the table it's self. The slowness issue takes place. (In short I have tried replacing HANSEN_CONTACT which is a view with the direct table link of imsv7.contact@HANSEN_REMOTE and that did not solve the timing issue).
Any ideas?

How to query the database in an Entity Object (EO)

I am using JDeveloper 11.1.2.2.0
I am Forms developer working in a new ADF project and need some help from the ADF gurus, I am just a ADF beginner.
Maybe hits question has a easy solution, but I don't know how to implement this:
I have simplified my scenario, but this is what I Need to do:
One database table DBTABLE with 3 columns (C1,N1,D1) C1-varchar2; N1-Numeric; D1-Date.
In the DBTABLE I have the following data:
ONE; 10; 01/10/2012
ONE; 20; 02/10/2012
TWO; 15; 02/10/2012
ONE; 15; 03/10/2012
I have created an ADF EO for the DBTABLE with all 3 attributes, then I have created another transient numeric attribute T1.
My requirement is when I create a new record and set attribute C1=ONE the transient attribute T1 should show sum(N1) from DBTABLE where D1>= 01/10/2012 and D1 < 03/10/2012.
In this case when I create a new record should the shown in T1 a total of 10+20 = 30.
I know how to use the EOImpl getters and setters, and how to set the T1 attribute when C1 is set. My problem is how to calculate the total T1.
How can I implement this in ADF? It is possible to implement this in the EO? It is possible to make the query select sum(N1) from DBTABLE where D1>= 01/10/2012 and D1 < 03/10/2012 and return the value to the EO attribute?
Thank you in advance

Hi Peter
Thank you for your suggestions, both of them are interesting but unfortunately they do not solve my problem, or at least I don’t know how.
I will try to better explain my problem
I have te table DBTABLE and another related table called DBDATES with colums(C1,DT1,DT2,TARGET) where I record periods of time and desired target. For instance my DBDATES table could have the following records
ONE; 01/01/2012; 31/01/2012; 100
ONE; 01/02/2012; 29/02/2012; 90
ONE; 01/03/2012; 31/03/2012; 95
TWO; 01/01/2012; 31/01/2012; 140
Exist a FK between both tables in the C1 column.
I have created an EO for the table DBTABLE with the tree persistent attributes (C1, N1, D1) an transient attribute (T1). The (C1,D1) is my DB primary key.
When I create a new record in the DBTABLE and based in the actual date I need to query the DBDATES table to check which is my TARGET and the valid target dates. For Instance if a record for person ONE is created on February 12, my TARGET is 90 from 01/02/2012 to 29/02/2012.
At the same moment I need to check the total amount of items record to the person ONE during the full target period.
Select sum(N1)
From DBTABLE
Where D1 between V2 and V3
And C1= V1;
Bind variables:
V1 = ‘ONE’;
V2 = ‘01/10/2012’ – queried from DBDATES
V3 = ‘03/10/201’ – queried from DBDATES
In resume, for a determined person when I create a new record in the DBTABLE I need to know their target for the actual period and how much as been record until now.
I don't know if is possible to solve this without using the View Objects, because I need to query the DBTABLE for a time frame and with bind variables.
Thank you in advance for your help.

How to get the Database table behind condition records

Hello All
In transaction VK13, after giving condition type, I can select sales document.
For a given Sales Document number, there are several conditions.
How can i extract all the conditions for a given sales document?
I am coding a report for this. In which database table can i get the condition between sales document number & different conditions attached to it?
On the screen, i can see that the fields are from the structure KOMG. What is the corresponding table?
Thanks

How to query cross-database?

I need do a query over a table on the connected database server and another table on another database server. How I can I do it in a easy way?
Can you write you query as easily as:
Select a, b from table 1, table2@server2 where a.c1=b.c1
The other question is:
If you close the database connection but do nothing with statement, will the statement get closed implicitly?
Thanks in advance,
YM

I need do a query over a table on the connected
database server and another table on another database
server. How I can I do it in a easy way?
Can you write you query as easily as:
Select a, b from table 1, table2@server2 where
a.c1=b.c1Some DBMSses have features that allow you to access tables on other databases (maybe on other servers even). The behaviour and the code syntax should be found in the docs.
No standart SQL.
Alternatively: your Java program can do several connections to several databases. So - not by a simple joined select, but by some more logic - you can do your cross-db query.
The other question is:
If you close the database connection but do nothing
with statement, will the statement get closed
implicitly?I think, yes. But you never know what some specific driver for some specific DBMS will do.
It's more clean to close the statement explicitely.
Either use the same statement(s) always, then create it/them directly after connecting and close it/them directly before the connection,
or create a new statement for each task and close it afterwards.

How to query a database file on my hard drive?

Hi,
I have a filer called "server.dbs" on my hard drive. It is a database file. I use a simple program that allows you to view databases, and it loads up and I can traverse the database and see all the entries as any standard database.
So I figured that Java's ability to handle SQL would allow me to make a standard SQL statement querying the database, and be able to get the results. The software stores servers in SID fields, and the value is the port the server runs on. I want to make a simple query to select a server by SID, and print the port in which that server is running on.
So is there any way to, via my java application, load a database from a file (rather than a url) which has no authentication required, and simply make my queries directly to that file? If so, how?
Thanks!
-Josh

Normal database access is via JDBC.
http://java.sun.com/docs/books/tutorial/jdbc/index.html
To use that JDBC driver is needed to access the database. Databases in wide usage all have one. It isn't clear from your posting that you have a common database though.

How to find the database table for this screen field

hi in XD02
There is a scrren field customer
name1 (firt line under name)
and email id fields
i wnat to know where the data stores goes w hen user eners in this screen i mean in which table and how to find it
for kunnr name1 i suppose it goes to kna1 but how to find it?
and f or email id whre it gots which table
regards
Arora

Hi,
when you press F1 it will give the necessary information
but some times it may give the structure names also
those structures are being used by the back end module pool
programm
so every time we can get the exact information about the
data type or length
but not sure that every time we get the exact database table name
and field name
according to me, if i dont know where some field are getting stored in
database ( if the field name and table is structure )
then i will ask my functional consultant ...
thanks & regards,

How to Import/Export database tables from one server to other in oracle8i

Hello friend,
Please can any one tell me how to import/export groups of database tables from one server with oracle to another using VB.net. It would be nice if some one can provide some code of it.
I am a software developer and I am in middle of a large project development, in which I need to export a large oracle database from one server to another efficiently.
Its very urgent so please someone help me.

At command prompt (source db)
set ORACLE_SID=db_name
exp system/password@db_name full=y buffer=104857600 file=(c:\file1.dmp, c:\file2.dmp....) log=c:\exp.log filesize=2000M
Then ftp the export dump files (in binary) to the other server or copy to target server over the network.
At command prompt (target db)
set ORACLE_SID=db_name
imp system/password@db_name full=y ignore=y buffer=104857600 file=(c:\file1.dmp, c:\file2.dmp....) log=c:\imp.log filesize=2000M
If the path names of the datafiles are going to be different in the target server (as compared to the source), then precreate the tablespaces before import. Set buffer value accordingly.

I have created 2 separate database tables in PHP/MySQL that I want to store user information in. The first user table I made the fields: id, username, password. The second table I made the fields: id, firstname, lastname, address, phone.
I want to make an update record page that is restricted by username and password that will update both table1 and table 2 from my MySQL database.
I have created a registration page, a login page and a restricted page for when the user signs in. On the restricted page I want to update the users information.
I have tried a few things and I can get the table that has the username field to update, I just can't get the second table to update with the first table.

Hmm.
Not sure where your going with the <select> menu.
The description you made:
"Both have an id column, which is presumably the record's primary key, but you need to create a relationship by storing the primary key of one table as a foreign key in the child (related) table. For example, you should insert the primary key of the first table in the second table as user_id. That enables you to identify which username and password are related to an individual listed in the second table"
Seems to be the direction that I'm looking for.
Now my question is how do I insert the primary key of the first table in the second table as user_id?

Since both tables have an id column and they both are the primary key, do I just change the name of the second tables id column to "user_id" then?
Or is there an actual "insert the primary key to another table" function that I don't know about?

How to access the database tables from application

Hii all,
The information in webcenter content, such as meta data fields, users, security groups etc are stored in
database tables like- Revisions, SecurityGroups, Users, DocType etc..
Can we access this tables from an adf application or any webcenter application..
If yes, then what can be the approach for that..??
Another things, how can we create custom tables just like the predefined tables...??
Any information regarding this.??
Thanks

Can we access this tables from an adf application or any webcenter application.Yes, you can - like to any other existing database. But I would strongly discourage you from any, but read-only access, or you can easily end up with inconsistent data.
If yes, then what can be the approach for that..??Just create a database connection and define in your model what tables you want to access.
Another things, how can we create custom tables just like the predefined tables...
Actually, WebCenter Content provides functionality of creation of custom tables (see http://docs.oracle.com/cd/E23943_01/doc.1111/e10978/c04_metadata.htm#autoId2 ) and these are probably the only good candidates for read-write access. See further in the manual what use cases are supported. Of course, you could do this even externally, but rather than Data Definition Language, I'd use services (if there are some).
