How to join several internal tables?

Hi,
I have several internal tables. And there is a very complex LOOP to extract data from these internal tables and many other logic inside it. The LOOP is very time-consuming.
I am thinking to join these internal tables into one big internal table, to save some logic inside the complex LOOP. But as I know there is no "join" function for internal tables.
So is there any workaround method to perform a "join" operation on internal tables?
Thanks a lot!

Hi Soubhik,
I have added two additional columns for each internal table.
Table_Count - It represents the Internal Table Number(ITAB1 -> 1, ITAB2 -> 2)
Row_Count - It represents the Row Count Number, increase the row count value 1 by one..
ITAB1:

Join 2 internal tables

Hello,
i have to join the whole content of a table with the content of a aggregated table. i "moved" the content of the 2 dictionary tables into 2 internal tables and i want to join these 2 internal tables now.
first of all, is it generally possible to join 2 internal tables, for example with a read or loop statement?!
at second, i know how i would solve the problem in oracle 10g, but it looks like that open-sql supports not the same features like orcale. knows anyone of you how i can rebuild the following oracle statement in abap.
select a.id, a.col1, b.col2
from table_a as a, (select id, sum(col2) as col2 from table_c group by id) as b where a.id = b.id order by 1
thx

Hello Markus
ABAP open sql ahould be something like
select aid acol1 sum( b~col2 )
from table_a as a
join table_c as b
on aid = bid
group by b~id
not sure abour the order by; don't know oracle syntax exactly.
Try!

How to define an internal table which have to be dynamic

Hallo,
here's a problem that i have to solve (but how ?).
I defined an internal Table with 2 columns:
col1: tablename
col2: fieldname
This table is filled with an unknown number of datasets like this:
dataset1: A001 KAPPL
dataset2: A001 KNUMH
dataset3: A903 KUNNR and so on.
I don't know which tablenames and fieldnames are contained.
Now i have to read those fields (e.g. KAPPL) from those tables (e.g. A001) into an internal table.
But i don't know how to define this internal table.
Could anyone help me please ?
Thanks a lot.
Silvio

Hi Wirth
DATA:
w_tabname TYPE w_tabname,
w_dref TYPE REF TO data,
table_name TYPE tadir-obj_name.
FIELD-SYMBOLS: <t_itab> TYPE ANY TABLE.
READ YOUR INTERNAL TABLE (DATA SET) AND GET THE TABLE NAME,
AND PASS IT TO W_TABNAME.
w_tabname = A001.
CREATE DATA w_dref TYPE TABLE OF (w_tabname).
ASSIGN w_dref->* TO <t_itab>.
Now use <t_itab> as your internal table to fetch data .
<t_itab> will have the structure of A001.
SELECT *
FROM (w_tabname) UP TO 10 ROWS
INTO TABLE <t_itab>.

please tell me how to copy complete internal table into main dababase table by overwriting all the entries of the main DBtable.

HI,
you can use<b> Insert Or Modify statement ..</b>
<b>Modify updates the existing record, insert creates a new one. ...</b>
insert ZDBTAB from table itab.
Modify ZDBTAB from table Itab.
The structure of itab should be exactly the same as the z table.
You should not update standard tables directly though.

How to combine 2 internal tables ?

how to combine 2 internal tables ? which statement is used to combine int tables ?

Instead of using the normal loop-endloop approach for this kind of programming, use the variation of the append command. Care should be taken that the definition of both the internal tables should be identical.
Not Recommended
            Loop at int_fligh1.
             Append int_fligh1 to int_fligh2.
            Endloop.
Recommended
            Append lines of int_fligh1 to int_fligh2.

How meny types of internal tables?

how meny types of internal tables? can any one explain brifly what r their use?

INTERNAL TABLES:
Internal tables are holds the data which is having the same structure and storing it in working memory in ABAP. The data is stored line by line in the memory. The main purpose of internal table is for storing and formatting data from a database table within a program. It is used to minimize the DB access time in report programs.
Internal table are dynamic data objects, since they can contain any number of lines of a particular type. The maximum memory that can be occupied by an internal table (including its internal administration) is 2 gigabytes.
Types of Internal Tables :
1. Standard Internal Tables :
Standard tables have an internal linear index. The system can access records either by using the table index or the key. The response time for key access is proportional to the number of entries in the table. This means that standard tables can always be filled very quickly, since the system does not have to check whether there are already existing entries. WE can fill a standard table by appending lines (ABAP APPEND statement), and read, modify and delete entries by specifying the index (INDEX option with the relevant ABAP command).
2. Sorted tables :
Sorted tables are always saved sorted by the key. They also have an internal index. The system can access records either by using the table index or the key. The response time for key access is logarithmically proportional to the number of table entries, since the system uses a binary search. Entries are inserted according to the sort sequence defined through the table key.
3. Hashed tables :
Hashed tables have no linear index. You can only access a hashed table using its key. The response time is independent of the number of table entries, and is constant, since the system access the table entries using a hash algorithm. we cannot access a hashed table using its index.
