Select data from database tables with high performance

hi all,
how to select data from different database tables with high performance.
im using for all entries instead of inner joins, even though burden on data base tables is going very high ( 90 % in se30)
hw to increase the performance.
kindly, reply.
thnks

Also Check you are not using open sql much like distict order by group by , use abap techniques on internal table to acive the same.
also Dont use select endselect.
if possible use up to n rows claus....
taht will limit the data base hits.
also dont run select in siode any loops.
i guess these are some of the trics oyu can use to avoid frequent DATA BASE HITS AND ABVOID THE DATA BASE LAOD.

How do you Select data from two tables with similar data amd merge the output together.

I have two Tables containing Sales Data. I want to read the Table a sort by date and accumulate dollars by order date. Then I want to read the second table and accumulate these dollar amounts by date and then merge the records together so that I gave 1 row
with amounts for type A and amounts for type b.
Here are the tables I am looking at.
Select Cast(J.Order_Date As Varchar(11))) As [Order Date]

Select max date from a table with multiple records

I need help writing an SQL to select max date from a table with multiple records.
Here's the scenario. There are multiple SA_IDs repeated with various EFFDT (dates). I want to retrieve the most recent effective date so that the SA_ID is unique. Looks simple, but I can't figure this out. Please help.
SA_ID CHAR_TYPE_CD EFFDT CHAR_VAL
0000651005 BASE 15-AUG-07 YES
0000651005 BASE 13-NOV-09 NO
0010973671 BASE 20-MAR-08 YES
0010973671 BASE 18-JUN-10 NO

Hi,
Welcome to the forum!
Whenever you have a question, post a little sample data in a form that people can use to re-create the problem and test their ideas.
For example:
CREATE TABLE     table_x
(     sa_id          NUMBER (10)
,     char_type     VARCHAR2 (10)
,     effdt          DATE
,     char_val     VARCHAR2 (10)
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('15-AUG-2007', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('13-NOV-2009', 'DD-MON-YYYY'), 'NO');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('20-MAR-2008', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('18-JUN-2010', 'DD-MON-YYYY'), 'NO');
COMMIT;Also, post the results that you want from that data. I'm not certain, but I think you want these results:
`    SA_ID LAST_EFFD
    651005 13-NOV-09
10973671 18-JUN-10That is, the latest effdt for each distinct sa_id.
Here's how to get those results:
SELECT    sa_id
,         MAX (effdt)    AS last_effdt
FROM      table_x
GROUP BY sa_id
;

Cartesian of data from two tables with no matching columns

Hello,
I was wondering – what’s the best way to create a Cartesian of data from two tables with no matching columns in such a way, so that there will be only a single SQL query generated?
I am thinking about something like:
for $COUNTRY in ns0: COUNTRY ()
for $PROD in ns1:PROD()
return <Results>
<COUNTRY> {fn:data($COUNTRY/COUNTRY_NAME)} </COUNTRY>
<PROD> {fn:data($PROD/PROD_NAME)} </PROD>
</Results>
And the expected result is combination of all COUNTRY_NAMEs with all PROD_NAMEs.
What I’ve noticed when checking query plan is that DSP will execute two queries to have the results – one for COUNTRY_NAME and another one for PROD_NAME. Which in general results in not the best performance ;-)
What I’ve noticed also is that when I add something like:
where COUNTRY_NAME != PROD_NAME
everything is ok and there is only one query created (it's red in the Query plan, but still it's ok from my pov). Still it looks to me more like a workaround, not a real best approach. I may be wrong though...
So the question is – what’s the suggested approach for such queries?
Thanks,
Leszek

Which in general results in not the best performanceI disagree. Only for two tables with very few rows, would a single sql statement give better performance.
Suppose there are 10,000 rows in each table - the cross-product will result in 100 million rows. Sounds like a bad idea. For this reason, DSP will not push a cross-product to a database. It will get the rows from each table in separate sql statements (retrieving only 20,000 rows) and then produce the cross-product itself.
If you want to execute sql with cross-products, you can create a sql-statement based dataservice. I recommend against doing so.

How to select data from a table using a date field in the where condition?

How to select data from a table using a date field in the where condition?
For eg:
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu = '31129999'.
thanks.

Hi Ramesh,
Specify the date format as YYYYMMDD in where condition.
Dates are internally stored in SAP as YYYYMMDD only.
Change your date format in WHERE condition as follows.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu = '99991231'.
I doubt check your data base table EQUK on this date for the existince of data.
Otherwise, just change the conidition on BDATU like below to see all entries prior to this date.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu <= '99991231'.
Thanks,

Reading Data from a Table With an Expert

Hi all - I'm trying to write an Expert in OWB that would read data from a table and create a new table based on that information. I have the table creation part down, but how can I read data from a table with an Expert? From what I've read, Experts only deal with metadata, and there is no mechanism in Experts to actually read data in the tables. Does OraTcl work in Experts? Has anyone ever came across this problem, and if so, how did you solve it? Thanks in advance for your time! - Don

Hi Don
Can also use Java and JDBC from within Tcl, see the routines in this file below, take modify or whatever;
http://blogs.oracle.com/warehousebuilder/ombora.tcl
source <dir>\ombora.tcl
set g_user scott
set g_upwd zzzzzz
set g_hostname localhost
set g_port 1521
set g_srvname ora111
oraconnect $g_user $g_upwd $g_hostname:$g_port:$g_srvname
oraselect "select * from emp" ""
As well as dumping the results to stdout (you probably want to comment that part out and change any other part you don't like), g_res is a ResultSet object you can use to do whatever.
Cheers

        proj~ernam
        proj~erdat
*        proj~pspnr " No need for this you have selected this in
*     the first line because it is commone so you only need to select from any one
        INTO TABLE itab
FROM prps INNER JOIN proj ON ( prps~pspnr = proj~pspnr )
WHERE prps~pspnr IN p_no.

Hi Manikandan,
The following code may be helpful to understand how to select the data from cluster table.
Types: Begin of ty_kna1,
Kunnr type kna1-kunnr,
adrnr type kna1-adrnr,
end of ty_kna1,
begin of ty_bseg,
belnr type bseg-belnr,
kunnr type bseg-kunnr,
end of ty_bseg,
begin of ty_final,
belnr type bseg-belnr,
kunnr type kna1-kunnr,
adrnr type kna1-adrnr,
end of ty_final.
Data: it_kna1 type table of ty_kna1,
wa_kna1 type ty_kna1,
it_bseg type table of ty_bseg,
wa_bseg type ty_bseg,
it_final type table of ty_final,
wa_final type ty_final.
Select kunnr adrnr from kna1 into table it_kna1 where....
if sy-subrc = 0.
select belnr kunnr into table it_bseg for all entries in it_kna1 where kunnr = it_kna1-kunnr.
endif.
sort it_kna1 by kunnr.
Loop at it_bseg into wa_bseg.
move wa_bseg-belnr to wa_final-belnr.
read table it_kna1 into wa_kna1 with kunnr = wa_bseg-kunnr binary search.
if sy-subrc = 0.
move: wa_kna1-kunnr to wa_final-kunnr,
wa_kna1-belnr to wa_final-belnr.
endif.
append wa_final to it_final.
clear wa_final.
endloop.
Loop at it_final into wa_final.
write: / wa_final-belnr, wa_final-kunnr, wa_final-adrnr.
endloop.
Reward if useful.
Thankyou,

It would appear that you external table definition and the external data file data do not match up. Post a few input records so someone can duplicate the problem and determine the fix.

How to select data from a table by passing document number from another tab

How to select data from a table by passing document number from another table.
for eg:-
I want to display name, adres, region from ADRC table
by using field delivery document number
Kind Regards,
Shanbagavalli.S

Hi Shanbagavalli,
There are multiple solutions to this questions a few i will try to answer and then you can take the best required for your requirements.
**Consider that you have a Internal table having document number from other table..
SELECT NAME ADRES REGION FROM ADRC
       INTO IT_ADRC
       FOR ALL ENTRIES IN IT_DOC
       WHERE DOCUMENT_NO = IT_DOC-DOCUMENT_NO.
**Consider that you have 1 document number then
SELECT NAME ADRES REGION FROM ADRC
     INTO IT_ADRC
     WHERE DOCUMENT_NO = W_DOCUMENT_NO.
Hope this solves your problem.

Kunjal

Select data from DataBase

I try to select data from DataBase, But I get the following error, Could anyone help? thanks.

It's a classpath problem. Either you mistyped the class name, or you don't have the class in your classpath. I think Oracle's drivers come in db12.zip or db12.jar or some such. Whatever that jar or zip file is, it has to be in your classpath, but it's not.
Or it is in your classpath, but you're in an appserver context where the classloader that the container provides for your app uses something other than the classpath variable. For instance, in tomcat, the jar file would be uder webapps/yourApplication/WEB-INF/lib I think.

Selecting data from two tables

I am trying to select data from two tables. The only problem that I am running into, is that i am only seeing results from my 'uploads' table. there is also a record in documents where user = 1 that should show up. here is my sql:
$userIDNum = 1;
$sql="Select *
from uploads, documents
WHERE uploads.user = documents.user AND uploads.user = $userIDNum
ORDER BY uploads.title ASC, documents.title ASC";

You'll need to explain a little more about your data and what you are trying to accomplish. Your current sql will select all columns from both the uploads and documents tables but only rows where the user id in both tables match, AND the user id equals 1. Is that not what you are seeing? Where's the code that outputs the results?

Select data from a table and a view: field with same content and different type

hi all,
I need data from a table hrp1001 and a view V_USR_NAME. What they have in common are the content of the fields SOBID and BNAME .
It will be easier if those fields add a same type but they dont.
Any suggestions for a workaround?
Thanks

Hi Ramesh,
Specify the date format as YYYYMMDD in where condition.
Dates are internally stored in SAP as YYYYMMDD only.
Change your date format in WHERE condition as follows.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu = '99991231'.
I doubt check your data base table EQUK on this date for the existince of data.
Otherwise, just change the conidition on BDATU like below to see all entries prior to this date.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu <= '99991231'.
Thanks,
