Hi friends i have doubt on select statement

hi friends, i am using one ztable which contains around 60 fields. i would like to consider in to itab around 52 fields. for this i am using "select * from ztable into itab....". can u please suggest me how can i improve by selecting all the fields and without reducing performance.

Declare as below:
Select-options: s_matnr FOR mara-matnr.
Data: Begin of itab.
INCLUDE STRUCTURE mara.
Data: End of itab.
Clear itab.
Refresh itab.
Select * from mara
into table itab
where matnr = s_matnr.
if sy-subrc = 0.
SORT itab.
endif.
OR if you are selecting based on some internal table then use
FO ALL ENTRIES IN itab1.
Hope this helps you, it will also improve your performance.

Hi friends i have doubt on collect statement.

i have some problem with matnr which is repeating no.of times. so i tried using collect and selected some of the fields to collect. Now i need to collect those collected elements in to internal table and need to display those fields in an ouput. for example.
loop at sumtab.
matnr type s886-matnr,
avg1 type p decimals 3,
total type p decimals 3,
endloop.
and now using loop i am collecting. these fields using my itab.
loop at itab.
move-corresponding itab to sumtab.
collect sumtab.
clear sumtab.
endloop.
***here itab contains no.of other fields like qty,stock etc.
so after here i am using ALV to display the itab.
my problem is how to make SUMTAB fields tobe moved in itab.

Hi Kalyan,
 The collect statement works like this . (ex)
data: begin of itab occurs 0,
 name(10) type c,
 value(4) type n,
 end of itab.
itab-name = 'JACK'.
itab-value = 100.
append itab.
itab-name = 'PAT'.
itab-value = 200.
append itab.
itab-name = 'JACK'.
itab-value = 200.
append itab.
sort itab.
loop itab.
collect itab.
write: / itab-name, itab-value.
endloop.
o/p:

I have doubt in Read statement

Hi All.
I have doubt in Read statement .i need to convert following select statement as read statement .how can i change help me.
IF p_field1 IS INITIAL
 AND p_field2 IS INITIAL
 AND p_field3 IS INITIAL
 AND p_field4 IS INITIAL
 AND p_field5 IS INITIAL.

 WHERE field5 = p_field5
 ORDER BY PRIMARY KEY.
 IF sy-subrc <> 0.
 MESSAGE s035.
 ENDIF.
ENDIF.

hi
The READ statement is as below:
When u have a table already with values and to improve the performance u need to use this.
Reading Lines of Tables
To read a single line of any table, use the statement:
READ TABLE <itab> <key> <result>.
For the statement to be valid for any kind of table, you must specify the entry using the key and
not the index. You specify the key in the <key> part of the statement. The <result> part can
specify a further processing option for the line that is retrieved.
If the system finds an entry, it sets SY-SUBRC to zero, if not, it takes the value 4, as long as it is
not influenced by one of the possible additions. If the internal table is an index table, SY-TABIX
is set to the index of the line retrieved. If the table has a non-unique key and there are duplicate
entries, the first entry is read.
Thanks
Shiva

Doubt about Select statement.

Hi folks!!
             I have a few doubts about the select statements, it may be a silly things but its useful for me.
what is   difference between below statment.
1)SELECT * FROM TABLE.
2)SELECT SINGLE * FROM TABLE

Hope i will get answer,thanks in advance.

Hi,
try this and if possible use sap help.i mean place the cursor on select and press F1.
             Types of select statements:
1.     select * from ztxlfa1 into table it.
             This is simple select statement to fetch all the data of db table into internal table it.
   2.   select * from ztxlfa1 into table it where lifnr between 'V2' and 'V5'.
        Thisis using where condition between v2 and v5.
4. select * from ztxlfa1 where land1 = 'DE'. "row goes into default table work Area
5. select lifnr land1 from ztxlfa1
        into corresponding fields of it   "notice 'table' is omitted
         where land1 = 'DE'.
          append it.
           endselect.
     Now data will go into work area. and then u will add it to internal table by
        append statement.

Doubt on Select Statement

HI Friends,
i have a requirement to select matnr,werks and mmsta from marc table.where i have input of matnr and mmsta.
The matnr in the marc table having 2 werks with different mmsta.
i was asked to select matnr not having mmsta 40.
but in marc table there is same matnr with two mmsta 37 and 40.
i want a select statement which should not pick matnr having 40.
my select statement was
select matnr werks mmsta into itab from marc
where matnr in fpso_matnr and mmsta in fpso_mmsta.
this does not work for the above condition.
please suggest me a correct statement..
Thanks,
Gokul

select matnr werks mmsta into itab from marc
where matnr in fpso_matnr and mmsta in fpso_mmsta
and mmsta NE 40.
ill this not work ?
MARC is plant data.. so I guess u need to give werks also...

Simple doubt in select statement

hi all,
Although this is a very simple ques.
Can u pl tell me why i m not getting the value into v_adrnr ?
Chk the following code.
V_VBELN = '0080000001'.
SELECT SINGLE ADRNR
         FROM VBPA
         INTO V_ADRNR
         WHERE VBELN = V_VBELN
         AND   PARVW = 'BP'.
i have cheked the table vbpa for the above mentioned conditions.I can see the
value for adrnr in database as 0000022741.
But while i run the above code i cant see value on v_adrnr.
Pl help.

First PARVW has a domain with a conversion routine based on table TPAUM so "BP" is internal code "RE"
Use CONVERSION_EXIT_PARVW_INPUT
CALL FUNCTION 'CONVERSION_EXIT_PARVW_INPUT'
EXPORTING
    input = V_PARVW
IMPORTING
    output = V_PARVW.
Second
Have you defined V_VBELN with reference to the element VBELN, char 10 with conversion Alpha
Then it should work

Doubt in select statement

Hi :
How can i join aufnr , arbei , ismnw since there is no common key field between arbei and aufnr , ismnw.
I am able to join aufnr and ismnw based on aufnr, because im trying to pull data based on aufnr , but when i went to se84 and tried to chk tables for arbei...only one table HIKO has all these fields but there is no data in that.
SELECT aaufnr aauart b~arbei INTO CORRESPONDING FIELDS OF TABLE it_tab
FROM aufk AS a
INNER JOIN plpo AS b ON awerks = bwerks
INNER JOIN iloa AS d ON abukrs = dbukrs
*06/18
INNER JOIN afko AS e ON aaufnr = eaufnr
WHERE a~auart IN s_auart

AND a~werks = 'M600'
AND d~tplnr = 'PB-PRO-S01-BY02-MIL'
AND d~abckz IN s_abckz
AND a~erdat IN s_date.
SELECT SINGLE ismnw INTO v_ismnw FROM afru
WHERE aufnr = v_aufnr.
it_tab-ismnw = v_ismnw.
with my first select statment do i get unique values for arbei?
i would appreciate if any one can help me on this.
Thanks.

I have doubt in Selection Screen

Hi all.
I was created Dialogue screen as a initial screen 9000. after that i changed 1000 as initial screen (Selection screen),Moved 9000 as second screen,i have some application tool bar in selection screen 1000.it is displaying when iam execute my program without transaction code.but it does not display when i execute programe by Transaction code,i was given screen no 1000 for t-code.
Regards,
Jay

Hi Jay,
Although i am not fully clear of the situation..please try the following suggestions that may prove useful..
1) for dummy sake try creating a new Tcode with dialog (option 1) again and see it you can achieve the desired output by running it...if not you can delete the new tcode you have created
Reason : Creating a fresh Tcode may put an end to your problem because i guess that you may have created the tcode first and reassigned the screens later......
2) try the "set PF status" code written in the module...if possible debugg in the Tcode and direct execute version marking the "Set PF status" as break point..
I am sure you can come up with something there...
ReAson : Last resort of any ABAPer is the debugger...

Hi friends i have doubt in dialog programming.

i am desiging the screen using table control. which is suppose to accept unit of measure as 'car' means carton, kg, and so on. so if i enter numerics it should not accept. can anybody tell me how can i restrict the user to enter only alphanumerics. thanks in advance.

Hello,
U can use the system table field ABCDE for checking if it has only alphabets.
system field == SY-ABCDE

Hi friends i have doubt on set cursor.

i am using dialog programming. here in the first text field i am auto generating the number, so user should only suppose to enter the values for other repective fields only.but in execution the cursor is positioning at the first field. it should start from the second and so on.
i tried using SET CURSOR FIELD F2. but tbe result is same. please provide me guidence on this.

Hi,
In the PBO of the dialog module,write the following code :
SET CURSOR FIELD `FIELD2`.
Remember the FIELD2 is the name assigned to the textbox of the screen.

Index not being used in Select statement

Friends
I have the following SQL statement:
SELECT
a.acct,
a.date_field,
UPPER(b.feegroup) feegrp,
SUM (a.fee1) fee1,
SUM (a.fee2) fee2,
SUM (a.fee3) fee3
FROM table1 a, table2 b
WHERE 1 = 1
AND a.fee_id = b.fee_id
GROUP BY a.acct, a.date_field, b.feegroup;
Both the tables have index on fee_id column. When I run the explain plan for this statement, I am getting the following output:
Operation | Option | Object Name | Position
SELECT STATEMENT | | | 560299
HASH | GROUP BY| |1
TABLE ACCESS | FULL| table2 | 1
TABLE ACCESS | FULL| table1 | 2
Why Oracle is not using the index?
Edited by: darshilm on Dec 10, 2009 3:56 PM

The proposed plan is the optimal according to your current conditions in the "where clause" where you have only the equality join condition and therefore the CBO can use HASH JOIN. Using any kind of index access would just increase the amount of required work unless you would add some very restrictive conditions which will select rows from relatively small amount of blocks. Here I have to mention that what really counts in the CBO cost calculation is the amount of blocks accessed and not the number of rows. The "currency" for I/O in Oracle is a block and not a row. CBO always uses an assumption that there is nothing in the buffer cache and it will have to perform a physical read for every block.
How many blocks will actually be accessed depends on the data distribution. It can happen that every single row that you have to retrieve resides in a different block and although you access only 1000 rows out of a million row table you would have to visit almost every block of that table. For such a situation a FULL TABLE SCAN is the best access path and Oracle will use multiblock I/O for that. On the other side you can have those 1000 rows only in a few blocks and then the index access would be the most appropriate one. For index access Oracle uses single block I/O. Usually the actual situation is somewhere between this two extreme situations. But you can run some tests by yourself and see when an index access will be replaced by a full table scan while you will make your predicates less selective.

If statement in select statement alias

I have the following select statement. It has the alias Survivors, Deaths and "All Cases". Is it posible to use :P_LANGUAGE variable to say that -- IF :P_LANGUAGE = FRENCH THEN alias are Survivants for survivors, Décès for Deaths, Tous_les_cas for All Cases. Please advise
SELECT ALL T_NTR_MULTIBAR.CAT, T_NTR_MULTIBAR.NUM_CASES_LEFTBAR AS Survivors,
T_NTR_MULTIBAR.NUM_CASES_MIDDLEBAR AS Deaths, T_NTR_MULTIBAR.NUM_CASES_RIGHTBAR AS "All Cases"
FROM T_NTR_MULTIBAR
WHERE INSTANCE_NUM = :P_INSTANCENUM
order by ORDERS

You may not be able to add this condition inside the SQL Statement. But you can add this condition outside the statement, if you're using PL/SQL...
IF :p_language = french THEN
SELECT ALL t_ntr_multibar.cat,
t_ntr_multibar.num_cases_leftbar AS survivors,
t_ntr_multibar.num_cases_middlebar AS deaths,
t_ntr_multibar.num_cases_rightbar AS "All Cases"
ELSE
END IF;

Increase performance of the following SELECT statement.

Hi All,
I have the following select statement which I would want to fine tune.
CHECK NOT LT_MARC IS INITIAL.
SELECT RSNUM
 RSPOS
 RSART
 MATNR
 WERKS
 BDTER
 BDMNG FROM RESB
 INTO TABLE GT_RESB
 FOR ALL ENTRIES IN LT_MARC
 WHERE XLOEK EQ ' '
 AND MATNR EQ LT_MARC-MATNR
 AND WERKS EQ P_WERKS
 AND BDTER IN S_PERIOD.
The following query is being run for a period of 1 year where the number of records returned will be approx 3 million. When the program is run in background the execution time is around 76 hours. When I run the same program dividing the selection period into smaller parts I am able to execute the same in about an hour.
After a previous posting I had changed the select statement to
CHECK NOT LT_MARC IS INITIAL.
SELECT RSNUM
 RSPOS
 RSART
 MATNR
 WERKS
 BDTER
 BDMNG FROM RESB
 APPENDING TABLE GT_RESB PACKAGE SIZE LV_SIZE
 FOR ALL ENTRIES IN LT_MARC
 WHERE XLOEK EQ ' '
 AND MATNR EQ LT_MARC-MATNR
 AND WERKS EQ P_WERKS
 AND BDTER IN S_PERIOD.
ENDSELECT.
But the performance improvement is very negligible.
Please suggest.
Regards,
Karthik

Hi Karthik,
Do not use the appending statement
Also you said if you reduce period then you get it quickly.
Why not try dividing your internal table LT_MARC into small internal tables having max 1000 entries.
You can read from index 1 - 1000 for first table. Use that in the select query and append the results
Then you can refresh that table and read table LT_MARC from 1001-2000 into the same table and then again execute the same query.
I know this sounds strange but you can bargain for better performance by increasing data base hits in this case.
Try this and let me know.

Hi Karthik,

Short dump with a select statement

I have the following select statement (I have also inluded my data statement(s)) and I get a short dump. The error is as follows:
What happened?
 Error in ABAP application program.
The current ABAP program "ZPARTNER" had to be terminated because one of the
 statements could not be executed.
This is probably due to an error in the ABAP program.
Following a SELECT statement, the data read could not be placed in AN
 the output area.
 A conversion may have been intended that is not supported by the
 system, or the output area may be too small.
Error analysis
 An exception occurred. This exception will be dealt with in more detail
 below. The exception, assigned to the class 'CX_SY_OPEN_SQL_DB', was not
 caught, which
 led to a runtime error. The reason for this exception is:
 The data read during a SELECT access could not be inserted into the
 target field.
 Either conversion is not supported for the target field's type or the
 target field is too short to accept the value or the data are not in a
 form that the target field can accept

 wa_adrc LIKE LINE OF it_adrc,
SELECT addrnumber name1 street city1 region post_code1 tel_number
FROM adrc INTO TABLE it_adrc
FOR ALL ENTRIES IN it_detail
WHERE addrnumber = it_detail-adrnr.
Regards,
Davis

If you only need the fields mentioned in the select query, then follow this:
TYPES: BEGIN OF ADRC_TYPE,
 ADDRNUMBER LIKE ADRC-ADDRNUMBER,
 NAME1 LIKE ADRC-NAME1,
 STREET LIKE ADRC-STREET,
 CITY LIKE ADRC-CITY,
 REGION LIKE ADRC-REGION,
 POST_CODE1 LIKE ADRC-POST_CODE1,
 TEL_NUMBER LIKE ADRC-TEL_NUMBER,
 END OF ADRC_TYPE,
 ADRC_T_TYPE TYPE TABLE OF ADRC_TYPE.
DATA: IT_ADRC TYPE ADRC_T_TYPE WITH HEADER LINE.
IF NOT IT_DETAIL[] IS INITIAL.
SELECT addrnumber name1 street city1 region post_code1 tel_number

FOR ALL ENTRIES IN it_detail
WHERE addrnumber = it_detail-adrnr.
ENDIF.

How to use SET ID in select statement of SQ02

Hi,
I have a infoset, where for one of my Zfield, i have writen a select statement in order to get my ouput.
if aufk-aufnr = 'XYZ'.
select sum( FKBTR ) from fmifiit into zfmifiit
where fikrs = aufk-kokrs
and fipex IN capex
and wrttp NE '51'.
endif.
For the above statement, i have created (with 10 single values, table name FMCI, field name FIPEX) a SET id named CAPEX and used with IN operator.
But when i generating the infoset i am getting error like below
The IN operator with "CAPEX" is followed neither by an internal table nor by a value list
I was using IN opeartor for set ids during validation / substitutions, where if i have to validate multiple single values.
What to do here?
