Suggestions for JSF table with sortale columns and Pagination

Hi,
My JSF application needs a table with sortable columns and also pagination.
Thank you.

Just add a bunch of commandlinks and/or commandbuttons at the right locations and invoke the appropriate logic in the backing bean.
You can find some useful insights in this article: [http://balusc.blogspot.com/2006/06/using-datatables.html].

Conflict resolution for a table with LOB column ...

Hi,
I was hoping for some guidance or advice on how to handle conflict resolution for a table with a LOB column.
Basically, I had intended to handle the conflict resolution using the MAXIMUM prebuilt update conflict handler. I also store
the 'update' transaction time in the same table and was planning to use this as the resolution column to resolve the conflict.
I see however these prebuilt conflict handlers do not support LOB columns. I assume therefore I need to code a customer handler
to do this for me. I'm not sure exactly what my custom handler needs to do though! Any guidance or links to similar examples would
be very much appreciated.

Hi,
I have been unable to make any progress on this issue. I have made use of prebuilt update handlers with no problems
before but I just don't know how to resolve these conflicts for LOB columns using custom handlers. I have some questions
which I hope make sense and are relevant:
1.Does an apply process detect update conflicts on LOB columns?
2.If I need to create a custom update/error handler to resolve this, should I create a prebuilt update handler for non-LOB columns
in the table and then a separate one for the LOB columns OR is it best just to code a single custom handler for ALL columns?
3.In my custom handler, I assume I will need to use the resolution column to decide whether or not to resolve the conflict in favour of the LCR
but how do I compare the new value in the LCR with that in the destination database? I mean how do I access the current value in the destination
database from the custom handler?
4.Finally, if I need to resolve in favour of the LCR, do I need to call something specific for LOB related columns compared to non-LOB columns?
Any help with these would be very much appreciated or even if someone can direct me to documentation or other links that would be good too.
Thanks again.

MERGE - WHEN MATCHED (for a table with 2 column that are the keys)

Hi
I am using merge to insert/update a table whenever new records come in.
My question is if the table has 2 columns and both are a part of the primary key, do I need to have the merge statement "when matched" as well? Since both the columns are part of the key, when matched wont make sense here. I will only need when not matched, then insert.
Please correct if I am wrong.
Thx!

You need to be matchning/not matching on the whole primary key. Matched and not matched are required before 10G.
MERGE   INTO table1 loctab
       USING (SELECT colpk1,
                     colpk2,
                     col3,
                     col4
              FROM   table2) remtab
          ON (loctab.colpk1 = remtab.colpk1 AND loctab.colpk2 = remtab.colpk2)
WHEN MATCHED
THEN
UPDATE SET loctab.col3 = remtab.col3,
                    loctab.col4 = remtab.col4
WHEN NOT MATCHED
THEN
INSERT          (loctab.colpk1,
                       loctab.colpk2,
                       loctab.col3,
                       loctab.col4
VALUES   (remtab.colpk1,
                remtab.colpk2,
                remtab.col3,
                remtab.col4
               );

Pivot Table with Dynamic Columns and Headers

Hello,
I'm trying to pivot a table of data where the column headers will be dynamic. While I know how to pivot the table to get what I want how will I be able to pick up the table column header from the Pivot to display in the report?
For example:
Unpivoted data is Employee Code, Branch Code, Problem Code, # of Problems.
There is many records for a given Employee and Branch that I want to pivot so the Column headers are the Problem Codes and the data below is the SUM(num_problems) for that Problem.
So the data may look like this for Tech Bob, Branch NY.
Problem = LEAK, Num_problem = 5
Problem = DAMAGE, Num_problem = 2
Problem = OTHER, Num_problem = 3
Which problem codes may appear is unknown but selecting the DISTINCT(problem) across all techs gives me the column headings to use.
So if I pivot this data, I get this Row:
Tech = Bob, Branch = NY, DAMAGE = 2, LEAK = 5, OTHER = 3
So first can SSRS handle having dynamic columns? Only Tech and Branch are known and the remaining columns are dynamic based on how many Problems they worked on.
Second, how can I set the column heading in my Tablix to be the Problem Code?
Sherry

You just need to use a matrix container
Use EmployeeCode and BranchCode for row group
ProblemCode as column group and SUM([No Of Problems]) as the data expression and it will generate the columns for you based on ProblemCode values automatically.

Compare tables in two schemas for the table with particular column & value

Hello All,
I have a query to find out the list of table from a given schema to extract all the tables having a search column .
ex :
SELECT OWNER, TABLE_NAME, COLUMN_NAME FROM
ALL_TAB_COLUMNS WHERE OWNER='<SCHEMA_NAME>'
AND COLUMN_NAME='<COLUMN_NAME>'
I want to compare two schemas for the same above query .
Can we wirte a query on this - I am using SQL DEVELOPER , which has menu item - TOOL - database differneces to find the diffenence between two schemas but my requirement is to find the differences in two schemas for all the tables matching for a particular column ( as given in quer).
Appreciate your help.
thanks/Kumar

Hi, Kumar,
This is the SQL and PL/SQL forum. If you have a question about SQL Developer, then the SQL Developer is a better place to post it. Mark this thread as "Answered" before starting another thread for the same question.
If SQL Developer has a tool for doing what you want, don't waste your time trying to devise a SQL solution. The SQL Developer way will probably be simpler, more efficient and more reliable.
If you do need to try a SQL solution, then post some sample data (CREATE TABLE and INSERT statements for a table that resembles all_tab_columns; you can call it my_tab_columns) and the results you want from that data.

Replication on the table with XMLType column and schema registered

Dear All,
Does Oracle XML DB 11g support replication for tables with schema registered?
Is there any recommended approach?
Thanks and regards,
Swapnil

Hmmmm ... I don't know if I should smile or frown with the implication that I am an OO guy :D :D
Most of my colleagues when I started working as a software engineer, treated me as too low-level because of my C background (started doing C in 1985).
In my last job, my colleagues hated my guts because I was asking them to squeeze every bit of performance out of C++ by using STL which is definitely not OO (although C++ is).
My current colleagues treat me as a DB guru (which I most definitely am not) and they overlook/forget the fact that most of them use Java libraries in their projects, that I wrote for them !
I am inclined to believe that I do not fall into any category in the end...
The only thing I am for sure - and I am proud of it - is inquisitive. I want to know everything there is about the tools I use, and so I end up spending hours and hours investigating... (Microsoft found that out the hard way when I filed 16 bug reports in 8 days when Visual C++ 6 came out ! Not that it hurt them though...)
This is where my confession ends (and my working on the XML validator starts...)

Spatial index on table with object-column (and inheritance)

Hi!
Is it possible to create a spatial index on a table with an object-column (and inheritance) like this:
CREATE OR REPLACE TYPE feature_type AS OBJECT (
shape MDSYS.SDO_GEOMETRY
) NOT FINAL;
CREATE OR REPLACE TYPE building_type UNDER feature_type (
name VARCHAR2(50)
CREATE TABLE features ( no NUMBER PRIMARY KEY, feature feature_type);
[...] user_sdo_geom_metadata [...]
Then
CREATE INDEX features_idx ON features(feature.shape) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
throws:
ORA-01418: specified index does not exist
Curious! :)
If I define feature_type with "NOT FINAL" option but without subtypes, I get (create index):
ORA-00604: error occurred at recursive SQL level 1
ORA-01460: unimplemented or unreasonable conversion requested
So I think besides object tables also inheritance isn't supported whith oracle spatial!?
Thanks,
Michael

How to create a table with editable column values.

Hi everyone,
I think this is very simple but i'm not able to find how to do this. This is my requirement. I need to create a table with n columns and 1 row initially. user should be able to enter data into this table and click of a button should insert data into the data base table. Also there should be a button at the bottom of the table to add 1 row to the table.
I know how to do the insert to database, but can anyone please let me know how to create a table that allows user to enter data and how to create a add 1 row button?
Thanks in Advance!

Raghu,
Go through the ToolBox tutorial Create Page & Advanced table section of OAF Guide.
Step 1 - You require to create EO & a VO based on this EO. This EO will be of DataBase table where you want to insert the data.
Step 2 - Create a Advanced table region. (Refer this Adavanced table section for more on this)
Step 3 - Attach this VO in the BC4J component of Adavanced Table region.

Bsp table with editable columns

Hi,
I want to create a table with some columns and include check box.
Is it possible?
I want to do this
Table :
Date   Time    Checkbox   Checkbox
Also how can i make the columns editable ?
Thank you

hello,
The basic idea would be use ITERATOR class reference in your 'Tavleview' HTMLB element
Iterator class should user interface 'IF_HTMLB_TABLEVIEW_ITERATOR', here you can modify column properties (GET_COLUMN_DEFINITIONS method) and cell properties (RENDER_CELL_START)
For your need:
RENDER_CELL_START method, example coding would be:
CASE p_column_key.
     WHEN 'Column name'.
    p_replacement_bee = cl_htmlb_checkbox=>factory(
                        id       = p_cell_id
                        _checked = p_cell_binding
                        disabled = 'X' ).
ENDCASE.
Thanks

Dropping a column in composite xmltype table with virtual column

Hi,
Please try this code:
loop at int_inv into wa_inv.
    lv_count = lv_count + 1.
    AT END OF posnr.   <------- The field you want to sum..
      gs_total-posnr      = wa_inv-posnr.

Find size of table with XMLTYPE column STORE AS BINARY XML

Hi,
I have a table with structure as:
CREATE TABLE XML_TABLE_1
ID NUMBER NOT NULL,
SOURCE VARCHAR2(255 CHAR) NOT NULL,
XML_TEXT SYS.XMLTYPE,
CREATION_DATE TIMESTAMP(6) NOT NULL
XMLTYPE XML_TEXT STORE AS BINARY XML (
TABLESPACE Tablespace1_LOB
DISABLE STORAGE IN ROW
CHUNK 16384
RETENTION
CACHE READS
NOLOGGING)
ALLOW NONSCHEMA
DISALLOW ANYSCHEMA
TABLESPACE Tablespace2_DATA
- So HOW do I find the total size occupied by this table. Does BINARY storage work as LOB storage. i.e. I need to consider USER_LOBS as well for this.
OR foll. will work
select segment_name as tablename, sum(bytes/ (1024 * 1024 * 1024 )) as tablesize_in_GB
From dba_segments
where segment_name = 'XML_TABLE_1'
and OWNER = 'SCHEMANAME'
group by segment_name ;
- Also if I am copying it to another table of same structure as:
Insert /*+ append */ into XML_TABLE_2 Select * from XML_TABLE_1.
Then how much space in ROllbackSegment do I need. Is it equal to the size of the table XML_TABLE_1?
Thanks..

I think foll query calculates it right while including the LOB storage as:
SELECT SUM(bytes)/1024/1024/1024 gb
FROM dba_segments
WHERE (owner = 'SCHEMA_NAME' and
segment_name = 'TABLE_NAME')
OR (owner, segment_name) IN (
SELECT owner, segment_name
FROM dba_lobs
WHERE owner = 'SCHEMA_NAME'
AND table_name = 'TABLE_NAME')
It's 80 GB for our Table with XMLType Column.
But for the second point:
Do we need 80GB of UNDO/ROLLBACK Segment for performing:
Insert /*+ append */ into TableName1 Select * from TableName;
Thanks..

Selection in table with Master Column

Hi,
can anybody explain me how selection works in table with MasterColumn (TreeByNestingTableColumn)?
I've created a table with several columns and the "master" one behaves differently from others.
First of all, leaf elements of master column are not clickable (i.e. I don't receive notification "onLeadSelect" from the table, when user clicks in the cell of leaf element of the column). With expandable elements I receive loadchildren event and can react on selection.
I'm using TextView as cell editor, will try LinkToAction, may be it will resolve situation, but it's rather workaround as solution
Second, getLeadSelection doesn't work anymore for the table - it works with indexes of top level elements only.
However onLeadSelect action brings me selected row number, which I somehow should map to the tree.
I.e. when I get "25" as selected element, I recursively traverse context node to find 25th element. Which is rather slow operation as for any selection I have to reiterate whole structure and I hope that visual appearance is similar to context element order.
May be there is simplier ways to get selected element by its index in "flat" list?
And one another strange thing: first click on the table sends me onLeadSelect "0", but highlight points to the element user clicked - not necessary first one.
Context node is "single" selection, initLeadSelect=true,
selection = 0..1 (with 1..1 setTreeSelection doesn't work - method I want to use to be able to select a node in hierarchy on my own)
all quite similar to other tables I have, which works well. Just the problems with the table, where Master Column is used.
Thank you!
Best regards,
Nick

>Valery's proposal was to perform reverse traverse from current element to root and summarize parent element indexes.
It seems to work:
in method, which sets selection I applied
// we need to know index of the element not in whole context, but in scope of table-relevant node
int index = getIndexInContext(selElement, wdContext.currentXXXElement());
IContextElement curContext = wdContext.currentContextElement();
int firstVisibleRow = curContext.getTableFirstVisibleRow();
int visibleRows = curContext.getTableVisibleRows();
if (index < firstVisibleRow || index > firstVisibleRow + visibleRows) {
curContext.setTableFirstVisibleRow(index);
and method getIndexInContext looks as:
    private int getIndexInContext (IWDNodeElement element, IWDNodeElement root) {
          int index = element.index();
          if (element == root) {
               return index;
          IWDNodeElement parent = element.node().getParentElement();
          if (parent == null) {
// do whatever you like here for error diagnostic
               myMsgMgr.reportException("Internal Error: getIndexInContext - element is not under passed root", false);
               return 0;
          // +1 - every level adds 1 (otherwise indexes of first children of hierarchy will be 0)
          return index + getIndexInContext(parent, root) + 1;
Best regards,
Nick

What index is suitable for a table with no unique columns and no primary key

Sample data above and below is the dataype for each one of them
alpha datatype- string
beta datatype-integer
gamma datatype-integer
col1,col2,col3 are all string datatypes.
Note:columns are not unique and we would be using alpha,beta,gamma to uniquely identify a record .Now as you see my sample data this is in a table which doesnt have index .I would like to have a index created covering these columns (alpha,beta,gamma) .I
beleive that creating clustered index having covering columns will be better.
What would you recommend the index type should be here in this case.Say data volume is 1 milion records and we always use the alpha,beta,gamma columns when we filiter or query records

Mudassar

Many thanks for your explanation .
When I tried querying using the below query on my heap table the sql server suggested to create NON CLUSTERED INDEX INCLUDING columns ,[beta],[gamma] ,[col1]
,[col2] ,[col3]
SELECT [alpha]
,[beta]
,[gamma]
,[col1]
,[col2]
,[col3]
FROM [TEST].[dbo].[Test]
where [alpha]='10100'
My question is why it didn't suggest Clustered INDEX and chose NON clustered index ?

ASSM and table with LOB column

I have a tablespace created with ASSM option. I've heard about that tables with LOB columns can't take the advantage of ASSM.
I made a test : create a table T with BLOB column in a ASSM tablespace. I succeeded!
Now I have some questions:
1. Since the segments of table T can't use ASSM to manage its blocks, what's the actrual approach? The traditional freelists??
2. Will there be some bad impacts on the usage of the tablespace if table T becomes larger and larger and is used frequently?
Thanks in advance.

Can you explain what you mean by #1 because I believe it is incorrect and it does not make sense in my personal opinion. You can create a table in an ASSM tablespace that has a LOB column from 9iR2 on I believe (could be wrong). LOBs don't follow the traditional PCTFREE/PCTUSED scenario. They allocate data in what are called "chunks" that you can define at the time you create the table. In fact I think the new SECUREFILE LOBs actually require ASSM tablespaces.
HTH!

HOW TO CREATE A TABLE WITH 800 COLUMNS?

I have to create a table with 800 columns.I know the create statement to create a table but it will take more time.
So tell me the other method.

If you really think that you have to store 800 values for a given entity, it would be a wise idea if you store you information in columnar fashion. Make a main table and a attribute table, keep the primary identifier in the main table and store other attributes in the attribute table where you can keep the primary key of the first table as foreign key (not necessary) to maintain the relationship.
eg.
emp_id
emp_name
dob
city
state
country
pincode
1
Mr X
01/01/1990
ABC
ZXC
MMM
12345
Can be stored as
Main Table
emp_id
emp_name
1
Mr X
Attribute Table
attr_id
emp_id
attr_nam
attr_value
1
1
dob
01/01/1990
2
1
city
ABC
3
1
state
ZXC
4
1
country
MMM
5
1
pincode
12345
Creating table with large number of columns is bad design as suggested by other Gurus.
Thanks
