An sample progam how to reterieve values from logical database

i need to reterieve prart, vernr, verna, from the table prps using the logical database psj, i know if i give psj in the logical database of the report attributes, but i should not give in the attributes, but i need to use the logical database.
i need a sample program

Here is the help on the subject.
<i>
Addition 2
... DEFINING DATABASE ldb
Effect
This addition shows that the current program is the database program of the logical database ldb. The name of this logical database has a maximum length of 20 characters. Logical databases are maintained with the tool Logical Database Builder of the ABAP Workbench, in which the framework program is generated automatically including the statement REPORT. The name of the framework program is SAPDBldb.
Example
Introduction of the logical database F1S.
REPORT sapdbf1s DEFINING DATABASE f1s.
</i>
This is leading me to believe that this extension DEFINING DATABASE F1S is used only when actually building the logical database via the LDB Builder, not for use when actually using it in a program.  I don't think that you can use this extension in your case.

  • How to load values from database into the f:selectItems value attribute

    Hi,
    I am trying to load the drop down menu value i.e f:selectItems from the database with a list of values from a column in the databse table. how can i do this? Should i use binding? or is there any other way.
    Note:i am able to load values into f:selectItems from the faces-config.xml file but they are static values. i want the values from the database
    Please reply with sample codes of faces jsp, bean file and config.xml file

    But this is working for me,
    JSF
         <h:selectOneMenu value="#{loadbean.grade}" >
              <f:selectItems value="#{loadbean.gradelist}" />
         </h:selectOneMenu>
    bean
    private String grade;
    private List<SelectItem> gradelist;
    public String getGrade() {
              return grade;
         public void setGrade(String grade) {
              this.grade = grade;
         public List<SelectItem> getGradelist() {
              return gradelist;
         public void setGradelist(List<String> items) {
              gradelist=new ArrayList<SelectItem>();
              gradelist.add(new SelectItem("daniel"));//this value can be from data base
              gradelist.add(new SelectItem("pspindia"));
              gradelist.add(new SelectItem("prelude sys"));
    faces-config.xml
    <managed-property>
              <property-name>gradelist</property-name>
              <null-value/>
    </managed-property>
    this working fine for me. So setter method also works to load value for the h:selectItems
    Thanks a lot.

    to the value I am searching. I am calling the set method in the
    first frame from the second frame to dispaly the values in the

  • How to read values from DMM4040

    Hi,
       I am using DMM4040, NI PXI 6509 device.
    I need to make some port pins high which i have already done and now i have to read value captured by DMM then i have to make my port pins low if my value is within limits.
    Can u suggest me how to read values from DMM and then by notification i ll make my port pins low.
    '' A professional is someone who can do his best work when he doesn't feel like it''...........

    What language are you using?  If using LabVIEW, you use the NI-DMM API to communicate with the 4040.  Just take your reading, do your limit comparison, and set your lines based on the comparison results.

  • How to get values from a stored package variable of type record ?

    Sir,
    In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
    What is the best way to do that ?
    Thanks
    Stephen

    Stephen,
    not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
    If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.
    Steve Muench provides the following examples on his blog page
