Dynamic table with field type table

Hi,
I´m using "cl_alv_table_create=>create_dynamic_table" to create a dynamic table for ALV Grid.
But...I need to use colors in ALV, then I need to declare a field type LVC_S_SCOL in dynamic table from "cl_alv_table_create=>create_dynamic_table".
How can I declare this in fieldcat?
The code:
Creating dynamic table

        line_agrup TYPE REF TO data.

Problem with coloring cells in dynamic fieldcatalog

Hi All,
I am trying to color cells based on the values in the cells. Here we are using dynamic fieldcatalog and internal table to build the ALV grid.I am getting problem in adding a field to the fieldcatlog which is of type lvc_t_scol. This Part of the code is used to build fieldcatlog dynamically.
DEFINE add_cat.
    add 1 to lv_count1.
    lwa_fldcat-col_pos     = lv_count1.
    lwa_fldcat-fieldname = &1 .
    lwa_fldcat-reptext   = &2.
    lwa_fldcat-inttype   = &3.
    lwa_fldcat-intlen    = &4.
    append lwa_fldcat to lt_fldcat .
END-OF-DEFINITION.
*Add Columns to the fieldcatalog
add_cat c_proj 'Project' 'C' '30'.
add_cat c_cust 'Customer' 'C' '30'.
lwa_fldcat-col_pos     = 12.
    lwa_fldcat-fieldname = 'cellcolor' .
    lwa_fldcat-reptext   = 'cell color'.
<b>    lwa_fldcat-inttype   = 'lvc_t_scol'.</b>
    append lwa_fldcat to lt_fldcat .
Here i want to assign internal table(lvc_t_scol) to the fieldcatalog as a field.But lwa_fldcat-inttype is of size 1 which will take one char. Is there any way that we can assign field of type internal table to the field catalog. Becoz of this i am unable to color cells in my ALV grid.
Thanks

INSERT TRIGGER WITH DATE

hi,
This may be a very basic doubt.please help me.
i m creating the dynamic table every month to maintain the particular month data seperately .when the records are getting inserted in the table,trigger will automatically insert the records in the dynamic table. In the ACTN_DATE column, only date alone(without timestamp) getting inserted in the dynamic table from main table. so by default ,00:00:00 is getting appended with date instead of actual timestamp present in the main table. tried select to_date(to_char(:new.ACTN_DATE,'YYYY-MM-DD HH24:MI:SS'),'YYYY-MM-DD HH24:MI:SS') INTO v_temp_actn_date from dual; then in the insert query ,i tried to insert the temp. variable v_temp_actn_date. but only date alone getting inserted in the dynamic table . In main table and dyanmic table datatype for date column is date .
actn_date value in main table 30-jun-2012 12:50:32 but actn_date value in the dynamic table is 30-jun-2012 00:00:00 . don't know why timestamp value is not present in the date field. please help me solve this issue .Thanks.

Welcome to the forum!
Whenever you post please provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION).
I don't understand how you data is getting inserted into each of the tables.
>
when the records are getting inserted in the table,trigger will automatically insert the records in the dynamic table.
>
What exactly is the trigger doing? What kind of trigger is it? What table is it on? Is the trigger inserting data into another table? Post the trigger code.
Please show the sample data from each table and the query that is being used to SELECT data from the one table and INSERT it into the main table.

What are dyanmic internal tables and what s the exact use of forall entries

what are dyanmic internal tables and what s the exact use of forall entries?

hi,
<u><b>dynamic internal table.</b></u>
http://searchsap.techtarget.com/tip/1,289483,sid21_gci912390,00.html
http://www.sap-img.com/ab030.htm
<u><b>
FOR ALL ENTRIES</b></u> is an effective way of doing away with using JOIN on two tables.
You can check the below code -
SELECT BUKRS BELNR GJAHR AUGDT
FROM BSEG
INTO TABLE I_BSEG
WHERE BUKRS = ....
SELECT BUKRS BELNR BLART BLDAT
FROM BKPF
INTO TABLE I_BKPF
FOR ALL ENTRIES IN I_BSEG
WHERE BUKRS = I_BSEG-BUKRS
AND BELNR = I_BSEG-BELNR
AND BLDAT IN SO_BLDAT.
*******************************8
look another example
what is the use of FOR ALL ENTRIES
1. INNER JOIN
DBTAB1 <----
> DBTAB2
It is used to JOIN two DATABASE tables
having some COMMON fields.
2. Whereas
For All Entries,
DBTAB1 <----
> ITAB1
is not at all related to two DATABASE tables.
It is related to INTERNAL table.
3. If we want to fetch data
from some DBTABLE1
but we want to fetch
for only some records
which are contained in some internal table,
then we use for alll entries.
1. simple example of for all entries.
2. NOTE THAT
In for all entries,
it is NOT necessary to use TWO DBTABLES.
(as against JOIN)
3. use this program (just copy paste)
it will fetch data
from T001
FOR ONLY TWO COMPANIES (as mentioned in itab)
4
REPORT abc.
DATA : BEGIN OF itab OCCURS 0,
bukrs LIKE t001-bukrs,
END OF itab.
DATA : t001 LIKE TABLE OF t001 WITH HEADER LINE.
itab-bukrs = '1000'.
APPEND itab.
itab-bukrs = '1100'.
APPEND itab.
SELECT * FROM t001
INTO TABLE t001
FOR ALL ENTRIES IN itab
WHERE bukrs = itab-bukrs.
LOOP AT t001.
WRITE :/ t001-bukrs.
ENDLOOP.
Hope this helps!

Sorting of Dyanmic internal table

Hi Gurus,
I am having a dynamic internal table (it_mat) having fields matnr uname field1,field2,field3 and field4.
the field is upto fieldN.
I want my table to sorted by this manner
Sort it_mat by field4 field3 field2 field1.
Sort it_mat by fieldN field(N-1)...field1.
Please help me in to get this in dynamic manner.

You can try something like this:
types : begin of ty_comps.
          include type abap_compdescr.
types: srl type i.
types : end   of ty_comps .
data: lt_comps type standard table of ty_comps,
         la_comps type ty_comps.
data: l_sort type standard table of char30 with header line.
loop at lt_tot_comp into la_comp.      " LT_TOT_COMP contains all my components
    move-corresponding la_comp to la_comps.
    la_comps-srl = sy-tabix.
    append la_comps to lt_comps.
    clear la_comps.
endloop.
sort lt_comps by srl descending.
loop at lt_comps into la_comps.
    l_sort = la_comps-name.
    append l_sort.
endloop.
sort <f_tab> by (l_sort).

Af: table color dyanmic

HI ,
Using jdev 11.6 .
I have requirement to show the table row/column in different color based on the some conditions . i have achieved by overriding the postQuery method and setting the color in transient attribute in voimple.
My questions related to the adf -style classes ,please provide style classes for over riding the table -column /row ? ( i m using the adf skining olny)
appreciate if any references ADF-css styles class sample for table row /column and also related to table row coloring based on the some conditions .
thanks

Why did you overwrite the post query method?
What are the conditions and now are they calculated?
Read Frank's article about skins http://www.oracle.com/technetwork/issue-archive/2011/11-nov/o61adf-512006.html This should get you started.

How to create a table with a dynamic amount of columns

Hi, all!
Thare is a tutorial at javaFX documentation page. This example describes how to make tableView, if you have some certain java class, which can tell you which columns you are going to have. (That is a Person class in this example).
But what if i do not have any specific class, and number of columns can vary from time to time? In my case i have such data structure:
class TableData{
    List<Row> rows; //A list with all my rows i need to have in my table
class Row{
    List<Column> columns; //Cells\Columns for every row.
class Column{
    Attribute attr; //Each column - is somethig like a wrapper for the real data i need to show in a cell;
class Attribute{ //My precues data
    String name;
    SupportingInfo info;
class SupportingInfo{//Some supporting fields...
    String name;
    String value;
    //...etc....
}So, my case is very similar to [this one|http://blog.ngopal.com.np/2011/10/19/dyanmic-tableview-data-from-database/] . The only differents is that data from the case above is not binded with its representation in javaFX table (so, even if some one will make extra controls to edit this data in a tableView, the actual object with that data will never know about it.), because it(data) goes to the table like some strings, not like some objects;
So, what do i need - is to push data to the table (like that: table.setItems(tableData)), set some set Factories, to give user ability to edit data, and to have this edited data in my tableData object;
Here are some code i've tried to make for this purpose:
//prepare my table
private void createTableHeader(TableView table, List<Attribute> ias) {
    int i = 0;
    for (final Attribute ia : ias) {
        final int j = i;
        i++;
        TableColumn tc = new TableColumn(ia.getName());
        tc.setSortable(true);
        tc.setCellValueFactory(new Callback<CellDataFeatures<List<Attribute>, String>, ObservableValue<String>>() {
            @Override
            public ObservableValue<String> call(CellDataFeatures<List<Attribute>, String> arg0) {
                if(arg0.getValue().get(j).getSupportingInfo() == null){
                    arg0.getValue().get(j).setSupportingInfo(new SupportingInfo());
                return new SimpleObjectProperty(arg0.getValue().get(j),"value");
        table.getColumns().add(tc);
//loading some data to my tableView
private void createTableBody(TableView curTable, List<Row> rows) {
    ObservableList<List<Attribute>> data = FXCollections.observableArrayList();
    for (Row row : rows) {
        data.add(row.getColumns());
    curTable.setItems(data);
//this one is to define some extra controls for editing data in a table by users
private void makeCellFactory(TableColumn curTableCol, final Attribute templateIa, final Document doc) {
    curTableCol.setCellFactory(new Callback<TableColumn, TableCell>() {
        public TableCell call(TableColumn p) {
            final EditingCell cell = new EditingCell(templateIa, doc);
            return cell;
}But, as a result, i have just empty rows in my table, with an ability to click some cell and recieve table editing controls. But there is not defult values in by table; What am i doing wrong in my code?

I put an example up on this thread No DataGrid component? with a TableView displaying values from a non-JavaFX aware data model. It might help get you started. This example is not editable, to make your table editable you would need to update the data model directly when editing is complete.
Note that if you're building the data model from scratch, there's no need for the listener-notification to be built by hand, as I did in the example. Your data model can directly use the same JavaFX collections instances the table is using.

Internal table with variable no of columns

Hi All,
I have to create an internal table with some fixed columns and rest of the table should be dynamic. The total no of columns depends on a field of some other table. hence, the number of columns of the table are unknown. How to create such a table.

How to fetch data from database in javafx 2.2 table which is editable.

Dears!
I want to fetch data from database in javafx 2.2 tableformat with jdbc , which is also editable and i can add more records in this table also.
Can anybody help me

I can vaguely recall some sort of JavaFX database connectivity feature, I'm not sure if it's valid anymore.The link is based on JavaFX Composer which only applied to NetBeans 6.9 and JavaFX 1.x (both of which are now dead techs).
There is a good chance you will have to write your own. There are several blogs describing other peoples' work. You could probably use them as a reference.Here is Narayan's basic [url http://blog.ngopal.com.np/2011/10/19/dyanmic-tableview-data-from-database/] tutorial for displaying data from a database in a TableView, you'll need to look elsewhere for the editing portion.
The [url http://docs.oracle.com/javafx/2/ui_controls/table-view.htm]JavaFX TableView tutorial gives info about how to handle edits in a TableView, but you will need to tie the updates back to the database yourself.
It is possible that [url http://www.javafxdata.org/]DataFX may provide some facilities to help support you.

How to add a table (dynamic created) into a model attribute

i have dynamically created an internal table. Generally i use model-binding in a stateful MVC-Application.
Is there a possibiltity to transfer the dynamic table to a model. As far as i know generic attributes are not allowed in the modell class.
Every hint welcome
thx in advance

By some miracle I do have this finally working. I will warn you up front that the code is not the cleanest (I have stuff copied in from all over the place. I probably have lots of unused variable references - but I am running out of time to clean it up further). Also I don't have all the logic to support all your different possible dynamic structure types. I always use SFLIGHT as my dyanmic structure. Therefore you will have to adapt the coding to lookup the actual structure type in use.
So I have a model that has an structure ITAB type ref to data. In my Model initialization I go ahead and dynamically redfine this to my specific type:
METHOD init.
SELECT SINGLE * FROM sflight INTO CORRESPONDING FIELDS OF isflight.
DATA: struct_type TYPE REF TO cl_abap_structdescr,
    tabletype TYPE REF TO cl_abap_tabledescr.
struct_type ?= cl_abap_structdescr=>describe_by_name( 'SFLIGHT' ).
CREATE DATA me->itab TYPE HANDLE struct_type.
ENDMETHOD.
Then in my View I have the following:
<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<%@extension name="phtmlb" prefix="phtmlb" %>
<%@extension name="bsp" prefix="bsp" %>
<htmlb:content design="design2003" >
<htmlb:page title=" " >
    <htmlb:form>
      <phtmlb:matrix width="100%" >
        <%
field-symbols: <wa> type any.
assign model->itab->* to <wa>.
* append initial line to <wa_itab> assigning <Wa>.
data: descriptor type ref to CL_ABAP_STRUCTDESCR.
descriptor ?= CL_ABAP_STRUCTDESCR=>describe_by_data( <wa> ).
data: flddescr type DDFIELDS.
flddescr = descriptor->GET_DDIC_FIELD_LIST( ).
field-symbols: <wa_field> like line of flddescr.
data: label type ref to cl_htmlb_label.
data: input type ref to CL_HTMLB_INPUTFIELD.
data: binding_string type string.
"Loop through each field in the structure Definition
loop at flddescr assigning <Wa_field>.
clear label.
clear input.
concatenate '//model/itab.'
<wa_field>-FIELDNAME
into binding_string.
label ?= cl_htmlb_label=>factory( _for = binding_string ).
input ?= cl_htmlb_inputfield=>factory( _value = binding_string ).
        %>
        <phtmlb:matrixCell row    = "+1"
                           vAlign = "TOP" />
        <bsp:bee bee="<%= label %>" />
        <phtmlb:matrixCell col    = "+1"
                           vAlign = "TOP" />
        <bsp:bee bee="<%= input %>" />
        <%
endloop.
        %>
      </phtmlb:matrix>
     <htmlb:button id="Test" onClick="Test" text="Submit"/>
    </htmlb:form>
</htmlb:page>
The key to making this work are custom getter/setters. In your model class, you can copy from the template methods (Like GETM_S_XYZ for the metadata structure method). Copy them and remove the _ on the front of the name. Then change XYZ to the name of the attribute you are binding for. The following are my custom methods.
method get_m_s_itab .

I know that is a LOT of nasty code without too much explanation. I'm afriad there isn't time right now to expand on how it works too much. Between my day job and trying to finish the BSP book, there just isn't much time left. Like I said before there is a very large section in the book on this topic that hopefully explains it. The book will be out in December or early January - but perhaps I will get some time before then to write up something on SDN about this.

How to Read data base table at runtime

Hi,
i have an internal table with two fields they are
   tablename and field name.
itab has some entries.
like :
itab-table name   itab-fieldname
kna1              kunnr
mara              matnr
vbuk              vbeln
tvak              auart
i want to read these tables with field names.
like :
loop at itab
   select singe * from <itab-tablename> into <jtab>
      where <itab-fieldname > = <dyanmic value from       prog>.
endloop.
Is it possible to read the db table in the above scenario.
Please try to give me the solution.
Thanks,
srik
