Query statement for internal table

is it possible to use a select statement to select data from an internal table? if yes, can anyone show me the codes to it? thx

Hi Daphne,
You use SELECT statement to read data from database table but not from Internal table.
For reading data from Internal table, you have to use READ statement.
Syntax:
READ TABLE itab { table_key
| free_key
| index } result.
Effect of using read statement:
This statement reads a row from internal table itab. You have to specify the row by either naming values table_key for the table key, a free condition free_key or an index index. The latter choice is possible only for index tables. The output result result determines when and where the row contents are read.
If the row to be read is not uniquely specified, the first suitable row is read. In the case of index tables, this row has the lowest table index of all matching rows.
Reward if usefull

Can we apply select statement on internal table.

can we apply select statement on internal table.if yes thrn let me know how to do.

Dear Sachin,
You cannot use SELECT statement on internal table.
If you want to select some rows from internal table you can LOOP the table or you can READ the table.
Please check the following links for your kind reference:

How many records are fetched my query into my internal tables

Hi
I am in the debugger, would like to know, how many records are fetched my query into my internal tables. How do I find out ?
thanks
siva

Hi,
Do the following,
Step 1:
Fill your internal table with select query.
Step 2 : Use DESCRIBE statement with LINE addition to get the no of rows in the internal table.

Update statement in Internal Table

Plz tell me the syntax and e.g. of update statement in Internal Table program
Moderator message: Welcome to SCN, please research yourself before asking basic questions.
Edited by: Thomas Zloch on Feb 25, 2010 12:47 PM

Hi,
Use UPDATE statement , check below description from SAP help.
UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
Effect
Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab.
The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.

Query related to Internal Table

Hi ,
I have a small query related to internal table , can we dump millions of records to an internal .
The actual requirment is like i need to develop a report in BI side where i have to dump records into an internal table from PSA tables without filtering .
Can we do so ....
or do we have any other option to dump the data to an internal tables .
need some tips on the same .
Thanks ,
VInay.

Hello Vinay,
I believe the following extract will give you a brief idea on the size limitations for an internal table.......
Internal tables are dynamic data objects, since they can contain any number of lines of a particular type. The only restriction on the number of lines an internal table may contain are the limits of your system installation. The maximum memory that can be occupied by an internal table (including its internal administration) is 2 gigabytes. A more realistic figure is up to 500 megabytes. An additional restriction for hashed tables is that they may not contain more than 2 million entries.
Hope it proved useful

System Variable For Internal table count

Can anybody tell me what the system variable for internal table count?
I just wants to know how many recoreds are there in my internal table ?
Regards,
pandu.

Hi ,
DESCRIBE TABLE <itab> [LINES <l>] [OCCURS <n>] [KIND <k>].
If you use the LINES parameter, the number of filled lines is written to the variable <lin>. If parameter, the you use the OCCURS value of the INITIAL SIZE of the table is returned to the variable <n>. If you use the KIND parameter, the table type is returned to the variable <k>: T for standard table, S for sorted table, and H for hashed table.
using variable
SY-TFILL
After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TFILL contains the number of lines in the relevant internal table.

Control statement in internal tables

hi experts,
can any body will provide me the control statement of internal table.
thank you

Hi,
check this link
http://help.sap.com/saphelp_nw2004s/helpdata/en/9f/db9f1f35c111d1829f0000e829fbfe/content.htm
Control Break Statements
Control break statements are used to create statement blocks which process only specific table lines the LOOP ENDLOOP block.
You open such a statement block with the control level statement AT and close it with the control level statement ENDAT. The syntax is as follows:
Table should be sorted when you use control-break statements
You can break the sequential access of internal tables by using these statements.
Syntax:
At first.
<Statement block>
Endat.
This is the first statement to get executed inside the loop (remember control break statements are applicable only inside the loop)
So in this block you can write or process those statements which you want to get executed when the loop starts.
At New carrid.
Write:/ carrid.
Endat.
In this case whenever the new carrid is reached, carrid will be written.
At End of carrid.
Uline.
Endat.
In this case whenever the end of carrid is reached, a line will be drawn.
At Last.
Write:/ Last Record is reached.
Endat.
Processing of statements within this block is done when entire processing of entire internal table is over. Usually used to display grand totals.
You can use either all or one of the above control break statements with in the loop for processing internal table.
At end of carrid.
Sum.
Endat.
In above case the statement SUM (applicable only within AT-ENDAT) will sum up all the numeric fields in internal table and result is stored in same internal table variable.

Why using workarea for internal table is better in performance

Please tell me
why using workarea for internal table is better in performance

Hi Vineet ,
Why would we choose to use an internal table without a header line when it is easier to code one with a header line?
it has following reason.
1)Separate Internal Table Work Area:
The work area (staging area) defined for the internal table is not limited to use with just one internal table.
take ex-
Suppose you want two internal tables for EMPLOYEE one to contain all records and one to contain only those records where country = USA. You could create both of these internal tables without header lines and use only one work area to load data into both of them. You would append all records from the work area into the first internal table. You would conditionally append the USA records from the same work area into the second internal table.
2) Performance Issues: Using an internal table without a header line is more efficient than one with a header line
3) Nested Internal Tables: If you want to include an internal table within a structure or another internal table, you must use one without a header line.
If this one is helpful ,then rewards me

Aggregate functions for internal table.

Hi Gurus,
I'm just wondering whether we can use aggregate functions for internal table. I wanted to know the max value for a particular column in my internal table. How can I achieve this easily and quickly.
Thanks,
David.

sort the table on which you want the maximum value and read it. Please find below example code.
TYPES : BEGIN OF ty_mvke,
        matnr TYPE mvke-matnr,
        vkorg TYPE mvke-vkorg,
        vtweg TYPE mvke-vtweg,
       AUMNG type mvke-AUMNG,
        END OF ty_mvke.
DATA : wa_mvke TYPE ty_mvke,
       it_mvke TYPE STANDARD TABLE OF ty_mvke.
data : temp_AUMNG type AUMNG.
START-OF-SELECTION.
SELECT matnr vkorg vtweg AUMNG FROM mvke INTO
        table it_mvke.
sort it_mvke by AUMNG.
read TABLE it_mvke into wa_mvke INDEX 1.
if sy-subrc = 0.
move wa_mvke-AUMNG to temp_AUMNG.
write : temp_AUMNG.
endif.

Extracting the result of a query into a internal table

Hi,
Does anyone knows or have an idea how to extract the result of a query into a internal table, is there a function module or BAPI?
Thanks in advance,
CK

So then normally I would use a statment like:
IFunctionTemplate ftemplate = repository.getFunctionTemplate("BAPI_SALESORDER_GETLIST");
to call a particluar function, but I tried using
IFunctionTemplate ftemplate = repository.getFunctionTemplate("BAPI_MDDATAPROVIDERBW_GETCATALOGS");
and it did not seem to work. I also tried -
IFunctionTemplate ftemplate = repository.getFunctionTemplate("MDDataProviderBW.GetCatalogs");
How do I format the function?
Thanks

Issue with WRITE statement from Internal Table

Hi All,
I have written the below code in a infoset query, the syntax check is ok & when i run the query in debugging mode, i find the internal table being filled with the values & the write statement outputing the values as well.
But the problem is when i execute the query the output does not show all the lines, instead just displays the last record . What could be the mistake?
Is it because i have defined Y_EBELN, Y_EBELP & Y_OPENQTY as nodes in the Extras Tab of the infoset & have chosen this for display in my query? How to display the output from my internal table in my query output?
Hope my problem is clear, await clarification.

Hi Vivek,
Try it like this.

       lifnr type lfa1-lifnr,
       name1 type lfa1-name1,
       land1 type lfa1-land1,
      End of itab,
      it_lfa1 like table of itab with header line,
      lifnr like lfa1-lifnr,
      name1 like lfa1-name1,
      land1 like lfa1-land1.
select lifnr name1 land1 into (lifnr, name1, land1)
       from lfa1.
it_lfa1-lifnr = lifnr.
it_lfa1-name1 = name1.
it_lfa1-land1 = land1.
append it_lfa1.
endselect.
loop at it_lfa1.
write:/ it_lfa1-lifnr, it_lfa1-name1, it_lfa1-land1.
endloop.
Note:
In place of the above select you insert your join select statement. It is working for me.
You have declared your internal table wrongly. In the internal table instead of TYPE use LIKE, it will work.
Hope this will work for you.

SAP QUERY LOOPS AND INTERNAL TABLE

Hi All, I have a query which i have made. It runs from Table EKPO which has PO details and what I want to do is now via ABAP Code pull through the total of goods receipt for the PO and Line Item into a field. Sounds Easy enough..Problem now,
The table which contains the GR data is EKBE which agains a PO and Line Item can have many 101 movements and 102 movements so what I want is an ABAP Statent to basically sum up the total of 101 for the PO & LINE ITEMS and then minus this from the total of 102 for the PO & LINE ITEMS and post the result in to this new field I have created.
I am pretty decent with ABAP Code in Querys I.e Select statements etc but from what I can see i need to create an internal table and do a loop and collect statement but I keep on failing due to not enough knowledge. Please can some one help me with this and provide me with the code and explanation as i would like to understand,
POINTS WILL BE REWARDED
Thanks

IMPORT Statement Issue (Internal Table)

Hi All,
I am using an IMPORT statement to get all the data from other report's internal table. Now whenever this (the other report's internal table) is changed (for field addition, etc), my report throws a dump. Hence, everytime I have to add these fields in my program as well.
Is there any way by which I can include the whole internal table of that report in my program just like
'INCLUDE STRUCTURE VBRK'.
Thanks in advance

Doubts with control break statements on internal table loops (AT/ENDAT)

Hi, i've had a couple of doubts for a long while which I hope someone can clarify today:
1) I know how to use the AT statements, however, i'm not sure I get correctly what this part of help regarding this commands means:
"The control level structure with internal tables is static. It corresponds exactly to the sequence of columns in the internal table (from left to right). In this context, the criteria according to which you sort the internal table are unimportant."
I've always sorted the internal table before the control break and it works that way. For example:
SORT ITAB BY EBELN EBELP.
LOOP AT ITAB.
AT NEW EBELN.
* Code for the order header
ENDAT.
ENDLOOP.
If I don't sort the internal table, it doesn't work! (i get dupplicated processing). In the example, if i have more than one register with the same EBELN and they're not consecutive, the header gets processed twice. I really don't get that part of the help text.
2) I know this: "At the start of a new control level (i.e. immediately after AT), the following occurs in the output area of the current LOOP statement:
All character type fields (on the right) are filled with "*" after the current control level key.
All other fields (on the right) are set to their initial values after the current control level key."
My doubt is: WHY is that this way? Because sometimes (most times) I need those fields INSIDE the statement! So when that happened i've solved it in one of three ways:
LOOP AT ITAB INTO WA_ITAB.
WA_ITAB_AUX = WA_ITAB.
AT NEW FIELD.
 WA_ITAB = WA_ITAB_AUX.
* ...Rest of the code for the first register
ENDAT.
ENDLOOP.
LOOP AT ITAB INTO WA_ITAB.
AT NEW FIELD.
 READ TABLE ITAB INDEX SY-TABIX INTO WA_ITAB.
* ...Rest of the code for the first register
ENDAT.
ENDLOOP.
* (Without AT)
LOOP AT ITAB INTO WA_ITAB.
IF WA_ITAB-FIELD <> FIELD_AUX.
 FIELD_AUX = WA_ITAB_FIELD.
* ...Rest of the code for the first register
ENDIF.
ENDLOOP.
Is there any problem with this way of coding? Can be done better?
Thank you very much in advance.

Hi..,
1)
See if u sort the table on a field on which u r using AT ENDAT .. then all the records which are having the same value for that field will form a group or those reocrds will be at one place.. so when u sort the table for all the records AT ENDAT will get executed onli once..
If u dont sort this table on this field then all these records will be at different places and in between there may be records with different value for this field.. so this AT ENDAT will get executed for each record !!
2)
No u cannot use the Right hand fields of the field in the table .. Because these AT events work as Group based operations... So till that field on which AT ENDAT is working it breaks that record into two groups.. One is the left hand fields including that field.. and right hand fields as another group.. and makes the right hand group as stars ****. Thats y u can observe that even any one field in the left hand group changes the AT ENDAT will get executed !!!!
Hope u understood !!!
