Wat is the exact differences between clustered table and pooled table

hi,
can you tell me ravi...wat is the exact differences between clustered table and pooled table
with regards//
anilreddyg

Hi Anil Reddy
Pooled Tables, Table Pools, Cluster Tables, and Table Clusters
These types of tables are not transparent in the sense that they are not legible or manageable directly using the underlying database system tools. They are managed from within the R/3 environment from the ABAP dictionary and also at runtime when they are loaded into application memory.Pool and cluster tables are logical tables. Physically, these logical tables are arranged as records of transparent tables. The pool and cluster tables are grouped together in other tables, which are of the transparent type. The tables that group together pool tables are known as table pools, or just pools; similarly, table clusters, or just
clusters, are the tables which group cluster tables.Not all operations that can be performed over transparent tables can be executed over pool or cluster tables.
For instance, you can manage these tables using Open SQL calls from ABAP, but not Native SQL.These tables are meant to be buffered and loaded in memory, because they are commonly used for storing internal control information and other types of data with no external (business) relevance. SAP recommends that tables of pool or cluster type be used exclusively for control information such as
program parameters, documentation, and so on. Transaction and application data should be stored in transparent tables.
Table Pools
From the point of view of the underlying DBMS as from the point of view of the ABAP dictionary, a table pool is a transparent table containing a group of pooled tables which, when created, were assigned to this table pool.
Field Type Description
TABNAME CHAR(10) Table name
VARKEY CHAR(n) Maximum key length n =< 110
DATALN INT2(5) Length of the VARDATA record returned
VARDATA RAW(m) Maximum length of the data varies according to DBMS
Table Clusters
Similarly to pooled tables, cluster tables are logical tables which, when created, are assigned to a table cluster. Therefore, a table cluster, or just cluster, groups together several tables of type clusters.Several logical rows from different cluster tables are brought together in a single physical record. The records
from the cluster tables assigned to a cluster are thus stored in a single common table in the database.A cluster contains a transparent cluster key which must be located at the start of the key of all logical cluster tables to be included in the cluster. As well, a cluster contains a long field (VARDATA), which contains the
data of the cluster tables for this key. If the data does not fit into a field, continuation records are created.
Field Type Description
CLKEY1 CHAR(*) First key fields
CLKEY2 CHAR(*) Second key field
CLKEYN CHAR(*) nth key field
PAGENO INT2(5) Number of the next page
TIMESTMP CHAR(14) Time stamp
PAGELG INT2(5) Length of the VARDATA record returned
VARDATA RAW(*) Maximum length of the data section; varies according to database system
Working with Tables
The dictionary includes many functions for working with tables. There are five basic operations you can perform on tables: display, create, delete, modify, copy. Please do not confuse displaying a table with displaying the table entries (table contents). In order to display a table, it must previously exist; otherwise the system will display an error message in the status bar. For the following example, the table TABNA is used. To display this table, from the main dictionary screen, enter the table name in the Object name
input field with the radio button selected next to Tables. Then, click on the Display button at the bottom of the screen, or press the F7 function key, or, alternatively,
select Dictionary object Display from the menu.
In this screen, you can see table information such as
¨ Table type, shown next to the name of the object. In the example, it is a transparent table.
¨ Short text description.
¨ Name of the user who made the last change, and the date of the change.
¨ Master language.
¨ Table status. On the screen, you can see this table is saved and active.
¨ Development class. For information on development classes, refer to Chap. 6.
Delivery class, which sets the maintenance group for the table. It controls how tables will behave during client copy procedures, upgrades, and so forth.¨
Tab. Maint. Allowed flag, which indicates whether you can generate a screen for maintaining table entries.
¨Then, on the lower part of the screen, you can see the table fields with all associated characteristics such as:
¨ Field name.
¨ Key indicator. When set, this field is the primary key, or part of it.
¨ Data element.
¨ Basic data type.
¨ Length.
¨ Check table.
¨ Short text, describing the field.
Additional information about the table can be displayed by selecting the corresponding functions from the menu or directly from the application toolbar, such as keys, indexes, or technical settings
Standard table:
The key access to a standard table uses a sequential search. The time required for an access is linearly dependent on the number of entries in the internal table.
You should usually access a standard table with index operations.
Sorted table:
The table is always stored internally sorted by its key. Key access to a sorted table can therefore use a binary search. If the key is not unique, the entry with the lowest index is accessed. The time required for an access is logarithmically dependent on the number of entries in the internal table.
Index accesses to sorted tables are also allowed. You should usually access a sorted table using its key.
Hash table:
The table is internally managed with a hash procedure. All the entries must have a unique key. The time required for a key access is constant, that is it does not depend on the number of entries in the internal table.
You cannot access a hash table with an index. Accesses must use generic key operations (SORT, LOOP, etc.).
Index table:
The table can be a standard table or a sorted table.
Index access is allowed to such an index table. Index tables can be used to define the type of generic parameters of a FORM (subroutine) or a function module.
Just have a look at these links:

To know the functionality of table control in ABAP Objects

Hi,
Is there any technique to achieve the functionality of table conrol in ABAP Objects?
Thanks.

Hello Raja
If you are using an editable ALV grid then you have the functionality of a table control and much much more.
ABAP-OO based ALV grids are much more powerful (and easier) than simple table controls.

Customise table inconsistency between ABAP Dictionary and the databas

Hi all,
I have encountered a problem where by, I was not able to activate a table due to inconsistency between ABAP Dictionary and the database.
After I run the SE14--> Check Database object. It has show that there is a missing Unique Index(Primary Index) at the Database Level, but at ABAP Dictionary it is there.
I have try to recreate the primary index at the Database level, but failed. Because one of the primary key field is been dropped from this table.
So now, may I know how can I still make this table Active again?
Is it save to folllow the following solution that I found on internet?
Syntax error in SDCC, table inconsistency between ABAP Dictionary and the database, transport error 8 during the generation of ABAP Dictionary. When you call Transaction SDCC, a termination occurs due to a putative syntax error because a table is not known or active. When you check this with the ABAP dictionary (SE11), you notice, that the table is active or inactive, however it is not possible to activate it. The activation might terminate with the error message 'Inconsistency between ABAP Dictionary and database'. A check of the affected object also delivers this error.
Solution
Proceed as follows:
Log on as user DDIC
Call Transaction SE14
Enter the affected table name and
select EDIT
In the following screen, choose Table -> Reconstruct
Confirm the execution
Call Transaction SE11
Enter the affected table name
Display
Activate

Make entries in a table in webdynpro abap

Hi all,
We have a requirement to make multiple entries in a Table in webdynpro ABAP.
We have created a table and inserted inputfield as cellEditor
but at runtime it is being displayed in readonly mode we cannot enter anything in that inputfield.
inputfield is binded with a context and table is not in readonly mode.
Please help in this regards
thanks & regards.....
Gaurav Makin

Hi Gaurav,
Make sure the context node bound to the table has cardinality 0..N.
When the app starts you probably need to read the table contents from the database or some other source and populate the contect node.
The table will allow the user to edit values only for the rows that have a corresponding element in the context node.
If the initial content is empty, i.e. no elements in the context node then the user will not be able to edit.
You will need to either initialize the context node with a bunch of elements if the number of entries is fixed and known beforehand, or provide a way for the user to create a new row.
You can do this by adding a toolbar to the table with a create button with a CREATE action and the following method:
method onactioncreate.
data:
lo_element type ref to if_wd_context_element,
lo_node type ref to if_wd_context_node.
lo_node = wd_context->get_child_node( name = 'your node name here' ).
lo_element = lo_node->create_element( ).
lo_node->bind_element( new_item = lo_element set_initial_elements = abap_false ).
endmethod.

How to load data to a "clustered table" quickly? direct insert not work

We have a single hash clustered table whose size is 45G, and we used the command:
insert /*+ append */ into t_hashed as select * from source.
the source is about 30G, it takes a very long time(several days, and not yet completed).
I dumped the redo log, and find there are lots of redo info about the insert. I have thought it should create much redo as it is "direct path insert", but from the dump info I could say the direct path insert didn't take effect.

Your assessment is correct. INSERT /*+ APPEND */ does not work with a hash clustered table.
If you think about how hash clusters work, and how direct load insert works, it should be clear to you why a direct load insert via the append hint can never work.
How hash clusters work (well, only the part that's relevant to the current discussion):
Initially, at creation time, the storage for the entire cluster is preallocated, based on the various cluster parameters you chose. Think about that. All the storage is allocated to the cluster.
How direct load works (well, only the part that's relevant to the current discussion):
Space already allocated to and used by the segment is ignored. Space is taken from free, unformatted blocks from above the high water mark.
So, hopefully it's clear how these features are incompatible.
Bottom line:
It doesn't work, there's no way around it, there's nothing you can do about it....

Create clustered table from heap table

Hi
I have a table with more than 15 million rows. I want to create a clustured table from this heap table and as you know, I can't use CTAS for clustered table
I created a clustered table and started insert data to it (Using append hint and parallel 16). Now, waiting 10 hours there's no result. What's the best way?
Thanks

a. you can use ctas:
SQL> select * from v$version;

Readind APO tables from ECC ABAP program

Hi,
I want to know if it is possible to read APO tables from a ABAP program in ECC 6.0.
If it is possible , please lt me know how?
Regards

Hi,
There's a remote-enabled function module (think it's either RFC_READ_TABLE or RFC_TABLE_READ) which you can pass a table name, some selection criteria and a list of fields to be returned. That should allow you to read those table entries from the remote system.

Tables in HANA / ABAP

Hi,
I have a question about the synchronization of tables between ABAP and HANA. When I create an se11 table in my ABAP on HANA trial system, the table is visible in the HANA studio schema SAPHANAABAP.
When I create a table in the HANA studio (same schema) , this table is not visible in the ABAP se11. Are these tables only exposed by procedures that are consumed in ABAP ?

Dear Marcus,
The tables and views maintained from ABAP Data Dictionary(SE11) gets created in the SAP<SID> Schema in the underlying HANA DB.
Nevertheless the opposite is not true, i.e when you create a DB artefact in HANA directly in HANA Studio it is not visible as a ABAP DDIC object and hence you cannot consume it in your ABAP code using Open SQL. If you need to consume them you need to use the HANA native artefacts. (I would really do a double check before doing so to verify if this is needed at all)
And this has been the case with any database which lies underneath the ABAP Application Server.
Hope this helps.
Thanks

Applying support packs, is there way to see all tables/view/clustered table

We are applying support packs, and they are taking awhile. Upon review it looks like it's adding some fields to some tables/clustered tables. Is there a way to see all the tables/views/cluster tables that were updated. I know I can look at version management, but if somebody can point me to the base tables to look at and I can do an sql to sort them for what I am looking for. I want to make the changes to the update tables ahead of time by adding the column at the end, so there's no need for a conversion.

you can find all the changes in Transport requests logs as below ;
PATH -> SAP******* -> you get package,general text,documentation,table,tabclecontents,porgram,view etc..
Plesae let me know if you have any questions?
