Sorting table in a jsp

Hello All,
I want to sort a result set by column name...I'm using MVC pattern ....so I have an if clause to decide the sorting order as:
<c:if test="${sort == asc}">
Student
</c:if>
<c:if test="${sort == desc}">
Student
</c:if>
I'm using a method in my action which sorts the given list ...so my question is how can i save the resultant List to be sorted ...if I put in request ...it can be displayed only one time and can i keep that in session....or is there any other better way to do this....
Thanks,
Maithri

The JSP generates HTML that is loaded into the browser. Are you asking whether something can be done in that HTML to put information into the next request?
Yes, it can. You could put a copy of the entire table into the next request by making it a whole lot of hidden parameters for the "Controller?sort=asc" URL. But now you are out into the realm of really stupid solutions, so don't do that.
The best solutions are:
1. Sort the data on the client using Javascript.
2. Store the data in the user's session and sort it on the server.
But you have already been told this several times.

Sorted Table - tabix issue

All,
I have the following code While executing system is pointing to sy-tabix, but the data I am getting in the READ statement is from last record in the internal table
report z_9699_30.
tables : eket.
types : begin of ty_eket.
        include structure eket.
types: end of ty_eket.
data: wa_eket                 type ty_eket.
data: it_eket                 like sorted table of wa_eket
                              with unique key primary_key
                              components ebeln ebelp etenr
                              with non-unique sorted key secondary_key
                              components ebeln ebelp.
parameters: p_ebeln like eket-ebeln.
parameters: p_ebelp like eket-ebelp.
select * from eket into table it_eket
      where ebeln eq p_ebeln.
      read table it_eket into wa_eket with table key secondary_key
               components ebeln = p_ebeln
                          ebelp = p_ebelp.
Please copy and execute this by giving EBELN and EBELP from EKET
Please make sure while selecting from EKET please select data of multiple records available for same EBELP ie llike
Here below PO # 4500000003 and for Item # 00030 is have multiple records
Here in selection screen by giving PO # as 4500000003 (EBELN) Item # as 00030 (EBELP) , then in the above READ statement system giving SY-TABIX as 3 but if you see the WA_EKET-ETENR is showing 2 instead of 1. This is where is the issue is
EBELN
EBELP
ETENR
Header 4
4500000003
00010
1
4500000003
00020
1
4500000003
00030
1
4500000003
00030
2

Now execute some
MOVE sy_tabix TO lv_index.
READ TABLE it_eket INTO wa_eket
      INDEX lv_index USING KEY secondary_key.
BREAK-POINT.
READ TABLE it_eket INTO wa_eket
      INDEX lv_index USING KEY primary_key.
BREAK-POINT.
and conclude yourself on the meaning of life index with two different keys defined...
Regards,
Raymond
PS: Reference in online help for sy-tabix now
Note that the sy-tabix system field is populated by the assigned secondary index, if sorted secondary keys are used. If this value is used for the subsequent index access to the internal table, the same table index must be explicitly used here. If used implicitly, the value would be interpreted as a primary index.

Hello Durga,
from the error what I understood is lt_key_values is a sorted table and you are trying append a new line to it. Incase of sorted table you need to use the INSERT statement and not the APPEND statement.
INSERT lw_key_value INTO table lt_key_values.

Short Dump While Changing Non-KeyField of Sorted Table

Hello,
A short dump occurs while trying to change a field of a sorted table item passed as CHANGING parameter. Are non-key fields in a sorted structure protected? The error message does not explicitely say so. Can anyone link to documentation explaining this behavior?
best regards,

You are passing by reference with CHANGING.
It looks like read-only stuff can't be passed to method CHANGING.
When I pass a literal or constant, there is a syntax error.
System could have given you a syntax error instead of dump.
Have a look at this snippet. Both method calls throw syntax error.

What's up when you drag and drop a table into a jsp page?

Hi All,
I was wondering what's happen in dragging and drop a table into a jsp page. This question because untill yesterday i had an application up and running, with a table displaying a number of rows of the database, and an action associated with an update into a database.
The action is managed trough JNDI, defined from Preference-Embedded.......
It was working.
Then the machine hosting the db changed IP addres. I went into Webcenter Administration console, I've changed the connection string into the jdbc parameters, by updating the new IP address... but it's not working anymore! The log comes out with a big error, but basically it can't connect at the db!
So, I think there is somewhere some reference to the old db.....where???
Thanks
Claudio

Yes Shay,
I got this error:
JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.DMLException, msg=JBO-26061: Error while opening JDBC connection.
in few hours I'll be able to give you the full stack.

Hi Shay,
Thanks a lot..you were right.
I've located the ba4j on the webcenter server...and I've noticed that it was with the old address.
I think it's a bug, cause on the local machine (before to deploy) this file comes with the right address.
So next time, before to redeploy a new application, I think I'm going to fiscally delete the folder from j2ee folder.
Thanks again for the help!

Standard versus sorted tables

Hi,
in SE30 (abap runtime analysis) i have tried to possible solutions for a DB access, and according to the performance tuning rules you should use sorted(or hashed) tables in stead of standard table, but in my case the runtime is almost equal. How is that possible ? Any explanations ?
Situation : table RSSELDONE, more than 80000 records
Code 1 with standard table - runtime 6.710.000 ms
data: i_tab type table of rsseldone,
 lwa like line of i_tab.
select * from rsseldone into table i_tab.
read table i_tab into lwa
with key rnr = 'REQU_3N57ZUZODOJ53FHTMO97BKDTH'.
Code 2 with sorted table - runtime 7.051.939 ms
data: i_stab type sorted table of rsseldone
 with non-unique key
 rnr
 initial size 0,
 lwa like line of i_stab.
select * from rsseldone into table i_stab.
read table i_stab into lwa
with table key rnr = 'REQU_3N57ZUZODOJ53FHTMO97BKDTH'.
Strange !

hi,
Standard Table - the most commonly used type of table. You can sort and resort this table anytime. You can have duplicate records in them. Recommend that when accessing these tables, you sort them by a key and then READ via a BINARY SEARCH - better performance. When you write to this table the record is "appended" to the end of the table. In order to maintain the sort sequence (if any) you must use the SORT command again.
Sorted table - this table has a defined sort sequence. You cannot resort. You can have duplicates. When you READ these tables, SAP automatically tries to use a BINARY SEARCH. Because you use a Binary Search, the retrieval time isexpodential to the number of records. When you write a record to this table the table is resorted.
Hashed Table - this table has a defined key. When you write to the table it uses a hashing algorithm to identify where the record is stored (think if this as writing the location of a page in an index of a book). When you READ this table the system looks up this "index" and retrieves the record. Because of this the retrieval time is constant. Writing to this type of table takes the most time as it needs to calculate the hashing algorithm.

Currency Format in Spry Sort Table

Any ideas on how to format all numbers in a spry sort table
into US currency? Currently on my site, Spry is not displaying the
".00" that is included in my XML file.
My
Spry Sort Table Example

Hi,
yes, I`ve had the same behavior. As a workaround, you have to change the format of the cells.
Go into the properties of the cells:
-> Right mouse click
-> format cells
-> category
-> number
-> change something, e.g. the number of decimal places to show
Then you will have to map the component again to the same cells under "Display Data".
And now, the currency information will be shown correctly.

Internal error - insert in sorted tabl ZADRU with

Hello Experts,
While i open BP transaction for one of the business partner. We are getting the following error:

Can't we use Binary SEARCH for TYPE SORTED TABLE?(Performance Improvement)

Hi Expert!
                   I have declare a sorted type table with NON -UNIQUE, and want to use Binary search in read statement. But while using bunary search in read statement I'm facing an error. The ERROR is
"Table LI_MARC is a SORTED TABLE or INDEX TABLE. The BINARY SEARCH
addition is only allowed for these tables if the key specified is an
initial part of the table key."
Please find detail
TYES: tt_marc TYPE SORTED TABLE OF marc   WITH NON-UNIQUE KEY matnr,werks.
DATA: li_marc type tt_marc.
READ TABLE li_marc INTO marc WITH KEY matnr = i_mbew-matnr
                                                                      werks = i_mbew-bwkey BINARY SEARCH .
To my understanding , there is no need to mention Bianry Search for sorted table TYPE. Please let me know can i use ?

Hello,
there is no need to mention Bianry Search for sorted table TYPE.
Yes, this is because for SORTED TABLEs binary search algorithm is used by default for READ TABLE. Although you can use BINARY SEARCH addition but it's use is redundant.
As for your case you've defined the KEY fields incorrectly There shouldn't be any "comma(s)" between the fields.
TYPES: tt_marc TYPE SORTED TABLE OF marc WITH NON-UNIQUE KEY matnr werks.
When you define it with commas
TYPES: tt_marc TYPE SORTED TABLE OF marc WITH NON-UNIQUE KEY matnr, werks.
the result is something like this:
TYPES: tt_marc TYPE SORTED TABLE OF marc WITH NON-UNIQUE KEY matnr.
TYPES: werks.
Hence you were getting the syntax error!
BR,
Suhas
PS: As for MARC you can use UNIQUE KEY addition because MATNR & WERKS are the key fields in the table.

Memory and performance when copying a sorted table to a standard table

Hello,
As you all probably know, it's not possible to use a sorted table as a tables parameter of a function module, but sometimes you want to use a sorted table in your function module for performance reasons, and at the end of the function module, you just copy it to a standard table to return to the calling program.
The problem with this is that at that moment, the contents of the table is in memory twice, which could result in the well known STORAGE_PARAMETERS_WRONG_SET runtime exception.
I've been looking for ways to do this without using an excessive amount of memory and still being performant. I tried four methods, all have their advantages and disadvantages, so I was hoping someone here could help me come up with the best way to do this. Both memory and performance are an issue.
Requirements :
- Memory usage must be as low as possible
- Performance must be as high as possible
- Method must work on all SAP versions from 4.6c and up
So far I have tried 3 methods.
I included a test report to this message, the output of this on my dev system is :

I've had another idea:
Create a RFC function like this (replace SOLI_TAB with your table types):
FUNCTION Z_COPY_TABLE .
*"*"Lokale Schnittstelle:
*" IMPORTING
*"     VALUE(IT_IN) TYPE SOLI_TAB
*" EXPORTING
*"     VALUE(ET_OUT) TYPE SOLI_TAB
et_out[] = it_in[].
ENDFUNCTION.
and then try something like this in your program:
DATA: gd_copy_done TYPE c LENGTH 1.
DATA: gt_one TYPE soli_tab.
DATA: gt_two TYPE soli_tab.
PERFORM move_tables.
FORM move_tables.
CLEAR gd_copy_done.
CALL FUNCTION 'Z_COPY_TABLE'
    STARTING NEW TASK 'ztest'
    PERFORMING copy_done ON END OF TASK
    EXPORTING
      it_in = gt_one[].
CLEAR gt_one[].
WAIT UNTIL gd_copy_done IS NOT INITIAL.
ENDFORM.
FORM copy_done USING ld_task TYPE clike.
RECEIVE RESULTS FROM FUNCTION 'Z_COPY_TABLE'
   IMPORTING
     et_out        = gt_two[].
gd_copy_done = 'X'.
ENDFORM.
Maybe this is a little bit faster than the Memory-Export?

Reading a sorted table in Sequence

Hi,
   I have a sorted table and want to read it in a sequence.
Say for example:
Table: sort by secondary key field2, non unique
Field1      Field2
10             100
20             100
30             100
Now, when i read the table with the secondray key, field2, I wnat that it should always return the data in same sequence i. e. 100, 200, 300
But currently when the sequence is not maintained liek it can be 100, 200, 300 or 200, 100, 300
Is it posisble that I get the same sequence every time.
Thanks & Regards,
Rupali Ray

Hi,
When you sort the table sort that table using the two fields that to in ascending order..
this will make the internal table records in sequence like
field1         field2
10            100
20            100
30             100
10             200
20             200
30              200
Now whilw reading the table using the key 2 as 100 or 200 the value of field1 will be in sequence as desired.
ie....             field1          field2
                    10              100
                     20             100
                    30               100
Hope this will help.
Regards,
Rohan.
