Regarding sy-index and sy-tabix

Hi,
What is the major difference between sy-index and sy-tabix ,
can you give me one good example with code..
Regards,
Reddy.

Hi,
SY-TABIX - Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY_INDEX - In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
sy-tabix is the tab index - the index of the record in the internal table you are accessing,
sy-index is the loop counter.
If you use a condition in LOOP the sy-index will go from 1 to n, but sy-tabix will refer to the line in the internal table.
Hope this helps u.
Thanks,
Ruthra

Hi Venkat,
1.SY-INDEX
->Current loop pass
->In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
2.SY-TABIX
->Current line index
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables.
The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.

SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
I think that it clears ur doubt.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

Difference b/w sy-index and sy-tabix

hai all,
Could u explain the difference b/w sy-index and sy-tabix?
regards,
Selva

Hi,
sy-index - For Loops, Current Loop Pass.
sy-tabix - For Internal Table, Current Line Index in internal table.
sy-tabix is used at internal table operations (READ TABLE ... LOOP AT ...), sy-index is used at cycles (DO...n TIMES).
SY-TABIX:
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
it can be set by using the following:
1.append
2.collect
3.loop at
4. read
5.search
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX:
SY-INDEX is used to describe the number of iteration with in the DO..ENDDO, WHILE ...ENDWHILE....
for example,
DO.
WRITE SY-INDEX.
IF SY-INDEX = 3.
EXIT.
ENDIF.
ENDDO.
it gives output as:
1 2 3

Which to use - Sy-index or sy-tabix ??

This is what i found out about SY-INDEX and SY-TABIX but which one to use when i want to delete a line of data from an internal table ? I tried both sy-index and sy-tabix and both works fine and returning the expected output for me but which one is better of to use ?
SY-TABIX :- For Internal Table, Current Line Index
SY-INDEX :- For Loops, Current Loop Pass
The below code is where i uses the Delete ..
LOOP AT dmg.
        CONCATENATE
               dmg-dmg00
               dmg-dmg01
               dmg-dmg02
               dmg-dmg03
               dmg-dmg04
               dmg-dmg07
               dmg-dmg08
               dmg-dmg09 INTO tli_down1 SEPARATED BY '*'.
        APPEND tli_down1. CLEAR tli_down1.
        DELETE dmg INDEX sy-index.
        EXIT.
      ENDLOOP.

Right. Just like what they said upstairs, sy-babix is the best choice.
One more thing is, if you want to concatenate fields of table dmg and append to tli_down1 on by one. You should not use EXIT after delete dmg.
In that case ,only one line can be appended into tli_down1 table.
> The below code is where i uses the Delete ..
>
> LOOP AT dmg.
>         CONCATENATE
>        dmg-dmg00
>         dmg-dmg01

>        dmg-dmg04
>         dmg-dmg07

>         dmg-dmg09 INTO tli_down1 SEPARATED BY '*'.

Regarding Indexes and performance tuning.

Hi Everyone,
I need some elaborate explanation about indexes and performance tuning.
1. How do you find out whether the select query which I write is utilizing the indexes .
2. Is it true that the sequence in which the indexes are defined in se11
for eg: MANDT
KNUMH
KOPOS
your select query should also have the same sequence in the where clause else the indexes are not utilized well .
3. Is there any precautions/ special method to write select queries for proper utilization of indexes.
Thanks to all reading and answering in advance.
Rgds,
Anu.

Hi
You will find like this
If your select like this
select matnr mtart from mara into<itab>
where matnr = <>..
Go to table and see mara ..if matnr is checked as primary key,then you are using primary index.
Check secondary index tab and see if any fields,if those fields you are using in select then you are using secondary index.
2.Not sequence,check how many fields are checked tick as primary key,all thsoe are index.
3.Always try to use proper primary index in select statment and avoid nested select statements.
Thanks

Sy-index vs sy-tabix

hi,
i a bit confused of these 2. can let me know the difference?
normally used in internal table?
what keyword can use these 2? read, insert, delete,loop, append, modify.
thanks

hi,
SY-INDEX
The system field sy-index contains the number of loop passes, including the current loop pass.
There are four kinds of loops in ABAP:
· Unconditional loops using the DO statement.
· Conditional loops using the WHILE statement.
· Loops through internal tables and extract datasets using the LOOP statement.
· Loops through datasets from database tables using the SELECT statement.
SY-TABIX
If the internal table is an index table, SY-TABIX is set to the index of the line retrieved.
READ
chk out this link http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb35f8358411d1829f0000e829fbfe/content.htm
APPEND sets SY-TABIX to the index of the last table row, that is the total number of entries in the target table.
LOOP AT sets SY-TABIX to the index of the current table row at the beginning of every loop pass. After leaving a loop, SY-TABIX is set to the value it had before entering the loop. With hashed tables, SY-TABIX is set to 0.
INSERT

Regarding deleting index

Hi Friends,
If I delete the whole content of an Infocube and then do the reload,is it require to delete the index seperately.
If I don't delete the index how is it going to impact the load?
Regards,
Debjani...

It doesn't mean that Indexes will delete permanently .. Structure will remain same!
When you delete data from cube it also deletes the generated indexes which are existed .. there is no point of having indexes on deleted records .. it's logical
even it doesn't hold any data it allows you to create index and generate stats(ex. create a dummy cube and try to generate)
For the moment I don't have any document for it.. I will let know
For your 2nd ques.
Only for huge loads droping index will be usefull which will improve the loading performance!
For daily delta load with less volume of data you need not to drop Indexes .. if you do so it will take lot of time to rebuild the indexes(on whole data)

Regarding Condition Index

Hi All,
With regards to condition index I have made the required tick in the condition type now when I am going into the master data with regards to creating condition records selecting the condition index tab by giving the input as the condition type, the system says that there are no records found, eventhough I have created the sales order in the system, the access sequence consists of line item and sales order please advise if any other configuration needs to be done for condition index and how do I check if the configuration is complete.
Kind Regards
Atul

Hi Condition indes only Specifies whether the system updates one or more condition indices when maintaining condition records. It depends whether you had created the combination of condition recored to determin if you can find the existing one, please be sure you had created the condition record via vk11.

What is RID in non clustered index and its use

Hi All,
I need help regarding following articles on sql server
1) what is RID in non clustered index and its use.
2) What is Physical and virtual address space. Difference in 32 bit vs 64 bit Virtual address space
Regards
Rahul

Next time Please ask single question in a thread you will get better response.
1. RID is location of heap. When you create Non clustered index on heap and
lookup happens to get extra records RID is used to locate the records. RID is basically Row ID. This is basic definition for you. Please read
this Thread for more details
2. I have not heard of Physical address space. I Know Virtual address space( VAS)
VAS is simple terms is amount of memory( virtual ) 'visible' to a process, a process can be SQL Server process or windows process. It theoretically depends on architecture of Operating System. 32 bit OS will have maximum range of 4 G VAS, it's calculated
like a process ruining on 32 bit system can address max up to 2^32 locations ( which is equivalent to 4 G). Similarly for 64 bit max VAS will be 2^64 which is theoretically infinite. To make things feasible maximum VAS for 64 bit system is kept to 8 TB. Now
VAS acts as layer of abstraction an intermediate .Instead of all request directly mapping to physical memory it first maps to VAS and then mapped to physical memory so that it can manage request for memory in more coordinated fashion than allowing process
to do it ,if not it will soon cause memory crunch.Any process when created on windows will see virtual memory according to its VAS limit.

First Try with JE BDB - Indexes and Inheritance troubles... (FIXED)

Hi Mark,
Mark wrote:
Hi, I'm a newbie here trying some stuff on JE BDB. And now I'm having
I am happy to help you with this, but I'll have to ask you to re-post this question to the BDB JE forum, which is...
Sorry for the mistake. I know now that here is the place to post my doubts.
I'm really interested in JE BDB product. I think it is fantastic!
Regarding my first post about "Indexes and Inheritance" on JE BDB, I found out the fix for that and actually, it wasn't about "Indexes and Inheritance" but "*Inheritance and Sequence*" because I have my "@Persistent public abstract class AbstractEntity" with a "@PrimaryKey(sequence = "ID_SEQ") private Long id" property.
This class is extended by all my business classes (@Entity Employee and @Entity Department) so that my business classes have their PrimaryKey autoincremented by the sequence.
But, all my business classes have the same Sequence Name: "ID_SEQ" then, when I start running my JE BDB at first time, I start saving 3 new Department objects and the sequence for these department objects star with "#1" and finishes with #3.
Then I continue saving Employee objects (here was the problem) I thought that my next Sequence number could be #4 but actually it was #101 so when I tried to save my very first Employee, I set the property "managerId=null" since this employee is the Manager, then, when I tried to save my second Employee who is working under the first one (the manager employee), I got the following exception message:
TryingJEBDBApp DatabaseExcaption: com.sleepycat.je.ForeignConstraintException: (JE 4.0.71) Secondary persist#EntityStoreName#com.dmp.gamblit.persistence.BDB.store.eployee.Employee#*managerId*
foreign key not allowed: it is not present in the foreign database
persist#EntityStoreName#com.dmp.gamblit.persistence.BDB.store.eployee.Employee
The solution:
I fixed it modifying the managerId value from "4" to "101" and it works now!
At this moment I'm trying to understand the Sequence mechanism and refining concerns about Cursors manipulation...
Have you any good material about these topics, perhaps a link where I can find more detailed information on these?
Thanks in advance Mark, thanks for your attention on this and I will post more doubts in the future for sure ;0)
Regards,
Diego

Hi Diego,
I fixed it modifying the managerId value from "4" to "101" and it works now!I'm glad you found the problem. It is usually best to get the assigned ID from the entity object after you call put(), and then use that value to fill in related fields in other entities. The primary key field (assigned from the sequence) is set by the put() method.
At this moment I'm trying to understand the Sequence mechanism and refining concerns about Cursors manipulation...Have you any good material about these topics, perhaps a link where I can find more detailed information on these? >
To find documentation, start at the first message in the forum, the Welcome message:
http://forums.oracle.com/forums/ann.jspa?annID=250
This refers to the main JE doc page, the JE FAQ and a white paper on DPL queries. The FAQ has a section on the DPL, which refers to the javadoc. The DPL javadoc has lots of info on using cursors along with indexes (see EntityIndex, PrimaryIndex, SecondaryIndex). The white paper will be useful to you if you're accustomed to using SQL.
I don't know of any doc on sequences other than the javadoc:
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/model/PrimaryKey.html#sequence()
This doc will point you to info on configuring the sequence, if that's what you're interested in.

Indexing and Deadlock in SQL Server 2008?

All,
I am running into a deadlock in SQL Server 2008. Using a profiler I was able to determine that the deadlock happens as I am trying to select and update row(S) in table in 2 different sessions.
The select query from the profiler is shown below
select
nodeinstan0_.id as id35_,
nodeinstan0_.BPMN_ELEMENT_ID as BPMN2_35_,
nodeinstan0_.END_DATE as END3_35_,
nodeinstan0_.NODE_ID as NODE4_35_,
nodeinstan0_.NODE_INSTANCE_ID as NODE5_35_,
nodeinstan0_.NODE_NAME as NODE6_35_,
nodeinstan0_.PROCESS_INSTANCE_ID as PROCESS7_35_,
nodeinstan0_.START_DATE as START8_35_
from
NODE_INSTANCE_LOG nodeinstan0_ where
nodeinstan0_.NODE_INSTANCE_ID= @P0 and
nodeinstan0_.PROCESS_INSTANCE_ID= @P1 and
(nodeinstan0_.END_DATE is null)
My SQL Scripts for creating the table and index is show below
CREATE TABLE [dbo].[NODE_INSTANCE_LOG](
[id] [numeric](19, 0) IDENTITY(1,1) NOT NULL,
[BPMN_ELEMENT_ID] [varchar](255) NULL,
[END_DATE] [datetime] NULL,
[NODE_ID] [varchar](255) NOT NULL,
[NODE_INSTANCE_ID] [varchar](255) NOT NULL,
[NODE_NAME] [varchar](2000) NULL,
[PROCESS_INSTANCE_ID] [numeric](19, 0) NOT NULL,
[START_DATE] [datetime] NULL,
PRIMARY KEY CLUSTERED
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE NONCLUSTERED INDEX IX_NODE_INSTANCE_LOG_Index1
ON NODE_INSTANCE_LOG(NODE_INSTANCE_ID, PROCESS_INSTANCE_ID, END_DATE)
INCLUDE
( ID, BPMN_ELEMENT_ID, NODE_ID, NODE_NAME, START_DATE);
As I understood from number of other forums and blogs - I have included the columns under the where clause in the "COVERING index" and the rest of the columns from the select query under non clustered Index. But I am still facing a deadlock.
Would appreciate if some once can point me in the right direction.
regards D

Correction to my earlier observation. Its not a select/update that's causing the deadlock but its a select/select
I am pasting an extract from the Tracer

Question about composite index and index skip scan

Hi,
I have a confusion.
I have read Burleson's post on composite index column ordering (http://www.dba-oracle.com/t_composite_index_multi_column_ordering.htm) where he writes that
"......for composite indexes the most restrictive column value(the column with the highest unique values) should be put first to trim down the result set..."
But 10g performance tuning book tells this about INDEX SKIP SCAN ::
"... Index Skip scanning lets a composite index be split logically into smaller subindexes. In skip
scanning, the initial column of the composite index is not specified in the query. In other words, it is skipped.
The number of logical subindexes is determined by the number of distinct values in the initial column.
Skip scanning is advantageous if there are few distinct values in the leading column of the composite index and many distinct values in the non-leading key of the index......."
So if we design Composite indexes acc. to what Burleson said then how can we take advantage of index skip scanning. These two staements oppose each other,don't they ?
Can anybody explain this ?

Dear,
For the moment forget the distinct values and the compressibility. I've tried to reproduce your case here below (using jonathan lewis table script)
create table t1
as
with generator as (
 select --+ materialize
 rownum id
 from dual
 connect by
 rownum <= 10000
select
 rownum c1,
 mod(rownum,1000) c2,
 mod(rownum,5000) c3,
 mod(rownum,10000) c4,
 lpad(rownum,10,'0') c5,
 rpad('x',5) c6
from
 generator v1,
 generator v2
where
 rownum <= 1000
alter table t1 add constraint t1_pk primary key (c3,c4,c5,C6);
create index idx_1 on t1 (c1,c2);
begin
 dbms_stats.gather_table_stats(
 ownname => user,
 tabname =>'T1',
 estimate_percent => 100,
 method_opt => 'for all columns size 1'
end;
/and here are what I got with your two selects
mho.sql>> SELECT c1,c2
2 FROM t1
3 WHERE c2 = 3;
 C1 C2

Trying to understand context indexes and contains-help

Hi
i am using
Achieving functionality of many preferences using one context index
to understand context indexes and contains
and i get the following
Error starting at line 1 in command:
begin
ctx_ddl.create_preference ('nd_mcds', 'multi_column_datastore');
ctx_ddl.set_attribute ('nd_mcds', 'columns', 'text nd, text text');
ctx_ddl.create_section_group ('nd_sg', 'basic_section_group');
ctx_ddl.add_ndata_section ('nd_sg', 'nd', 'nd');
ctx_ddl.create_preference ('test_lex', 'basic_lexer');
ctx_ddl.set_attribute ('test_lex', 'whitespace', '/\|-_+');
end;
Error report:
ORA-06550: line 5, column 15:
PLS-00302: component 'ADD_NDATA_SECTION' must be declared
ORA-06550: line 5, column 7:
PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
so i am using the following to check for the error
http://docs.oracle.com/cd/E18283_01/text.112/e16593/cddlpkg.htm#BABCBFCB
plus
oracle text application developer's guide
plus
oracle text reference
but these have not listed that error (i have even googled this in vain)
background::we were actually using catsearch but because of its downsides i want to implement this
Is Achieving functionality of many preferences using one context index a good place to start when one does not know about
context and contains??
please post any other useful link for contains and context index that even explains
1) fuzzy
2) stem
3) synonym
4) near
5) soundex
6)ndata
7)lexer
thanks in advance

Ndata is new to Oracle 11g. Your other posts indicate that you are using Oracle 10g, so you don't have ndata, so you get an error when you try to use it. If you want to use the 11g features that enable context indexes with contains to do all of the things that ctxcat indexes with catsearch do, then you need to upgrade to 11g.
The online documentation is searchable. Most things regarding Oracle Text are contained in either the Oracle Text Reference or the Oracle Text Application Developer's guide.
I suggest that you start with something very simple, then build from there.
The following is similar to your other post that used catsearch:
SCOTT@orcl_11gR2> CREATE TABLE mv_cat_seg_reg_prod
2 (cat_ids VARCHAR2 ( 7),
3 act_status VARCHAR2 (10),
4 name VARCHAR2 ( 1),
5 email VARCHAR2 ( 1),
6 address1 VARCHAR2 ( 1),
7 address2 VARCHAR2 ( 1),
8 contact_name VARCHAR2 ( 1),
9 mobile VARCHAR2 ( 1),
10 telephone VARCHAR2 ( 1))
11 /
Table created.
SCOTT@orcl_11gR2> INSERT ALL
