Table compare

hi all,
i have a dought of comparing two tables , i have two internal tables , in one internal table i am fetching data from ztable and other from the standard table. then i need to compare both the record and perform some task based on true and false. please suggest . my requirement from spec is as follows.
compare both Create and Change dates/time. For all records that has different date/time, output in an ALV report:
1.For each record, compare the CREATE_DAT, CREATE_TIM as well as CHANGE_DAT, CHANGE TIM between I_AGR_DEF and I_CT.
a.If different date/time, output the record in ALV.
b.If record exist in I_AGR_DEF but not in I_CT, output record in ALV
c.If record do not exist in I_AGR_DEF but exist in I_CT, output record in ALV.

do this way ...
loop at itab.
read table itab1 with key field1 = itab-field1.
if sy-subrc = 0.
write:\ itab-field1.
endif.
endloop.

Table compare deleting rows which does not exist in target table

Hi Gurus,
I am struggling with an issue in Data Services.
I have a job which uses Table Compare, then History Preserving and then a Key Generation transforms.
There is every possibility that data would get deleted from the source table.
Now, I want to delete them from the target table also.
I tried Detect deleted rows but it is not working.
Could some one please help me on this issue.
Thanks,
Raviteja.

Doesn't history preserving really only operate on "Update" rows. Wouldn't it only process the deletes if you turned the "Preserve Delete row(s) as update row(s)" on?
I would think if you turned on Detect Delete rows in the Table compare and did not turn this on in the history preserving it would retain those rows as delete rows and effectively remove them from the target.
Preserve delete row(s) as update row(s)
Converts DELETE rows to UPDATE rows in the target warehouse and, if you previously set effective date values (Valid from and Valid to), sets the Valid To value to the execution date. Use this option to maintain slowly changing dimensions by feeding a complete data set first through the Table Comparison transform with its Detect deleted row(s) from comparison table
option selected.

Get the values from a table comparing fields of different data types

Hi Experts,
I want to fetch AFVC-AUFPL and AFVC- APLZL by passing WBS element from a ztable.
select aufpl aplzl
from afvc
into TABLE gt_afvc
FOR ALL ENTRIES IN gt_boq
where projn = gt_boq-posid.
AFVC-PROJN - NUMC 8 (WBC ELEMENT)
ZTABLE-POSID - CHAR24 (WBC ELEMENT)
How to get aufpl and aplzl by comparing those 2?
Regards
Mani

WBS element does have an conversion routine at the domain level. So sometimes you work with one format (8 digits) and sometimes with 24 digits.
You use FMs
CONVERSION_EXIT_ABPSP_INPUT
CONVERSION_EXIT_ABPSP_OUTPUT
to convert between values. Do your conversion before your select and do not forget to use a large enough data element for the field, which gets the 24-digits long value of the field.

Script for comparing 2 schemas based upon table compare

Hi,
I want to write a script on 2 schemas TEST and TEST1 which will compare the difference in tables in both schemas and will Insert Data
into schema TEST from TEST1 depending upon the matched columns in schema TEST and TEST1
Any help will be nedful for me

I want to write a script on 2 schemas TEST and TEST1 which will compare the difference in tables Differences in METADATA or differences in data.?
It would be helpful if you provided DDL for tables involved.
It would be helpful if you provided DML for test data.
It would be helpful if you provided expected/desired results & a detailed explanation how & why the test data gets transformed or organized.

Merging SAP Clients - Reporting on Cross Client Table Compare Results

Hey folks,
We are trying to merge two clients into one (on the cheap), i think that cross client table comparision is the best way to find differences and possible issues and clashes with the two systems configuration, but i was wondering if there is anyway to report on these differences, so we can pull them out to word/excel document to anaylse and document them prior to making the changes.
Does anyone know if this possible?
Thanks a lot,
Greg

Hello Mr. Newman,
I think using SCU0 is going to be the way to go but the output is not always the best. However you should be able to show the differences and download to excel to analyse further. If this doens't fit then I think you will have to look at copying the tcode / report and improving the output to meet your needs.
Alternatively post to basis folks and see if they have some better ideas!
Hope this helps,
Cheers,
Dan

Table compare and derive alter script between 2 schemas

I am in Oracle 10g.
We are in need to synchronise table structures between two different database.
and execute the alter script in the target database.
I have an idea to find the tables which have the table definition changed using all_tab_columns and datbase link;
A sample of it as below:
prompt
prompt columns having same name but difference in datatype or length:
prompt -------------------------------------------------------------------------
select
a.column_name, a.data_type, a.data_length, a.data_scale,a.data_precision,
b.column_name, b.data_type, b.data_length, b.data_scale,b.data_precision
from
all_tab_columns a, all_tab_columns@link b
where
a.table_name in (select tablename from test) and
a.table_name = b.table_name and
a.column_name = b.column_name and
a.data_type <> b.data_type or
a.data_length <> b.data_length or
a.data_scale <> b.data_scale or
a.data_precision <> b.data_precision
prompt columns present in &table1 but not in &table2
prompt ----------------------------------------------
select
column_name
from
all_tab_columns@link
where
table_name in (select tablename from test)
minus
select
column_name --, data_type, data_length, data_scale, data_precision
from
all_tab_columns
where
table_name in (select tablename from test) ;
prompt columns present in &table2 but not in &table1
prompt ----------------------------------------------
select
column_name --, data_type, data_length, data_scale, data_precision
from
all_tab_columns@link
where
table_name in (select tablename from test)
minus
select
column_name
from
all_tab_columns
where
table_name in (select tablename from test)
just looking for idea to derive the alter scripts on these? Please share your ideas on this.

You don't have to write lots of triggers. You only need to write one trigger e.g :-
create table ddl_audit
(audit_date date,
username varchar2(30),
instance_number integer,
database_name varchar2(9),
object_type varchar2(19),
object_owner varchar2(30),
object_name varchar2(128),
sql_text varchar2(2000));
create or replace trigger BEFORE_DDL_TRG before ddl on database
declare
l_sql_text ora_name_list_t;
l_count NUMBER;
l_puser VARCHAR2(30) := NULL;
l_sql varchar2(2000);
begin
l_count := ora_sql_txt(l_sql_text);
l_puser := SYS_CONTEXT('USERENV', 'KZVDVCU');
l_count := ora_sql_txt(l_sql_text);
for i in 1..l_count
loop
l_sql := l_sql||l_sql_text(i);
end loop;
insert into ddl_audit (audit_date, username, instance_number, database_name, object_type, object_owner, object_name, sql_text)
values (sysdate, l_puser,ora_instance_num,ora_database_name,ora_dict_obj_type,ora_dict_obj_owner,ora_dict_obj_name,l_sql);
exception
when others then
null;
end;
show errors;

Article number is missing for a sales document in VBAP table compared to BW data.

Hi,
We are loading data from 2LIS_11_VAITM and 2LIS_11_V_SSL to 0SD_O01, when we execute a report based on this DSO we are getting Article number 2224859 (for example) for sales order 573345 (for example) but when we check in VBAP/VA03 for the same sales order/document (573345) we don't have the Article Number.
It is delta load to the DSO from the two datasources and will executed daily once.
Please suggest me any one on this.

All,
Thanks for your replys.
Here are the more details about this.
We are using 3.X flow in BW. (3.x Data sources)
In BW                                           Mapping                In ECC
0DOC_NUMBER    Sales document -----------> VBELN          Sales Document
0MATERIAL           Material -----------------------> MATNR           Article Number
In VBAP table, I have entered Sales document 573345 and executed then I got so many Article Numbers and Filtered with Article Number 2224859 then got no data.
As I told earlier in BW for the same Sales Document number we have Article Number.
We have start routine.
PROGRAM UPDATE_ROUTINE.
*$*$ begin of global - insert your declaration only below this line *-*

I think there is no much more lookups. ( I don't have much knowledge in ABAP)
I have checked in another tables also like VBFA VBAG VBAK, VBKD, VBUK and VBUP but in those tables I don't have Article (MATNR) field.
One more Question.
Can any one tell me how the Queued Delta mechanism will work.
As of now I know that, when ever any changes have been done to the tables this will pickup the changes and move into LBWQ after that RSA7.
My Question is, If some one has forcefully deleted one Article number from the table for a Sales Order then this Queued delta will pick that also?
Please let me know If you need any more details

How to compare each row in an internal table

Hi,
Say I have an internal table with 3 fields in each row, num1, num2, num3, each type of integer i, now I want to get the maximum of num1, num2, num3 and put this maximum number into num4, may I know how can I do that? Also, if say I need to pull out this num4 and play around with it, sould I just loop it into my workarea of internal table and assign a variable for whatever that is in the work area? Thanks a lot!
Regards,
Anyi

Hi,
Inside a loop of the table compare each field like this:
loop at itab.
l_num4 = itab-num1.
if l_num4 < itab-num2. l_num4 = itab-num2. endif.
if l_num4 < itab-num3. l_num4 = itab-num3. endif.
Here you can play with the maximum number
itab-num4 = l_num4.
modify itab.
endloop.
You can also do the same using field-symbols (it's faster to assignations) :
loop at itab assigning <a>.
endloop.
Regards.

PL/SQL Pipelined Function to Compare *ANY* 2 tables

I am trying to create a pipelined function in 10g R1 that will take the name of two tables, compare the the tables using dynamic SQL and pipe out the resulting rows using the appropriate row type. The pipelined function will be used in a DML insert statement.
For example:
create table a (f1 number, f2, date, f3 varchar2);
create table b (f1 number, f2, date, f3 varchar2);
create table c (f1 number, f2, date, f3 varchar2);
create or replace TYPE AnyCollTyp IS TABLE OF ANYTYPE;
create or replace TYPE CRowType IS c%ROWTYPE;
create or replace TYPE CRowTabType IS table of CRowType;
CREATE OR REPLACE FUNCTION compareTables (p_source IN VARCHAR2, p_dest IN VARCHAR2)
RETURN AnyCollTyp PIPELINED
IS
CURSOR columnCur (p_tableName IN user_tab_columns.table_name%TYPE)
IS
SELECT column_name, column_id
FROM user_tab_columns
WHERE table_name = p_tableName
ORDER BY column_id;
l_cur sys_refcursor;
l_rec ANYTYPE;
l_stmt VARCHAR2 (32767);
BEGIN
l_stmt := 'select ';
FOR columnRec IN columnCur (p_dest)
LOOP
l_stmt := l_stmt || CASE
WHEN columnRec.column_id > 1
THEN ','
ELSE ''
END || columnRec.column_name;
END LOOP;
l_stmt := l_stmt || ' from ' || p_source;
l_stmt := l_stmt || ' minus ';
l_stmt := l_stmt || ' select ';
FOR columnRec IN columnCur (p_dest)
LOOP
l_stmt := l_stmt || CASE
WHEN columnRec.column_id > 1
THEN ','
ELSE ''
END || columnRec.column_name;
END LOOP;
l_stmt := l_stmt || ' from ' || p_dest;
OPEN l_cur FOR l_stmt;
LOOP
FETCH l_cur
INTO l_rec;
PIPE ROW (l_rec);
EXIT WHEN l_cur%NOTFOUND;
END LOOP;
CLOSE l_cur;
RETURN;
END compareTables;
The pipelined function gets created without error. However, the testCompare procedure gets an error:
SQL> create or replace procedure testCompare is
begin
insert into c
select *
from (TABLE(CAST(compareTables('a','b') as cRowTabType)));
dbms_output.put_line(SQL%ROWCOUNT || ' rows inserted into c.');
end;
Warning: Procedure created with compilation errors.

Errors for PROCEDURE TESTCOMPARE:

Does anyone know what I am doing wrong? Is there a better way to compare any two tables and get the resulting rows?

Avoid SUPPLEMENTAL LOG while comparing 2 tables using dbms_metadata_diff()

Hi,
I am using ORACLE DATABASE 11g R2. I am using a inbuilt package dbms_metadata_diff.compare_alter() to compare 2 tables and get the alter statements for them. I have applied GOLDEN GATE on one of the Schema's and as per the process we need to apply SUPPLEMENTAL LOGGING on the database. So when 2 tables are compared it also gives me the difference about the SUPPLEMENTAL LOG. I want to compare 2 tables but it should avoid the difference of the SUPPLEMENTAL LOG group.
Below is a part of code which I use :-
dbms_metadata.set_transform_param(DBMS_METADATA.SESSION_TRANSFORM, -- Parameter to keep the DDL pretty.
                                            'PRETTY',
                                            TRUE);
          dbms_metadata.set_transform_param(DBMS_METADATA.SESSION_TRANSFORM, -- To put an SQL terminator(;) at the end of SQL.
                                            'SQLTERMINATOR',
                                            TRUE);
          dbms_metadata.set_transform_param(dbms_metadata.session_transform, -- Not to consider the SEGMENT attributes for comparison.
                                            'SEGMENT_ATTRIBUTES',
                                            false);
          dbms_metadata.set_transform_param(dbms_metadata.session_transform, -- Not to include the STORAGE clause.
                                            'STORAGE',
                                            false);
          dbms_metadata.set_transform_param(dbms_metadata.session_transform, -- Not to include the TABLESPACE Info.
                                            'TABLESPACE',
                                            false);

                                                  V_SOURCE_SCHEMA_NAME,
                                                  null,
                                                  'DBLINK_TEMP')
            into V_TAB_DIFF_ALTER
            FROM dual;In the current case for all tables i get the output as below :- (sample table output)
ALTER TABLE "BANK"."BA_EOD_SHELL_DRIVER" DROP SUPPLEMENTAL LOG GROUP GGS_BA_EOD_SHELL_DR_199689;I don't want such alter statements in my output as i am not going to execute this on the schema , because i need SUPPLEMENTAL LOG for GOLDEN GATE.
Please suggest me some solution on it.
Thanks in advance.

It probably won't answer the question...
The DBMS_METADATA_DIFF.COMPARE_ALTER function will return a CLOB containing all the ALTER TABLE statements.
I have noticed that you hold your resoult in V_TAB_DIFF_ALTER variable. Why don't you search what you need and remove it?
"The DBMS_LOB package provides subprograms to operate on BLOBs, CLOBs, NCLOBs, BFILEs, and temporary LOBs. You can use DBMS_LOB to access and manipulation specific parts of a LOB or complete LOBs."

Merging of multiple rows in an internal table as a single record

Hi All,
I have an internal table which has the following columns:
text, date, time, user.
it stores notes in the internal table.
The problem is...when I save a note with multiple lines and spaces it saves each line of the note as a row in the internal table.
Thus i get more no. of rows in the internal table compare to the no. of rows!
I need to store each notes as single row in the internal table.
Please advise how to approach this?
Helpful answers will be rewarded.
Thanks & Regards,
Anshumita.

You can create a deep internal table. You can declare one Column as an internal table and store the NOTES in that Internal table for each row.

Are there any (dis)advantages in building a universe on fully normalized tables instead of building dimensional model/tables and then universe on top of them?

Hello,
I’m hoping someone can help me with understanding advantages and disadvantages if we want to build a universe on top of a fully normalized tables, compared to using a dimensional model with star schemas.
I’ve read some discussions here that say that it is possible to create a universe on top of normalized tables. Then, can we avoid building of dimensional tables (a data mart), and just use normalized tables? I would say that it is easier to use star schema dimensions and facts tables to build a universe, but our end users might ask “why do we have to go through building a dimensional data mart, if we can have same reports with hierarchies and drill-down functionality based on a universe built on top of our already existing normalized tables?”
Can you point me to some established best practices regarding using normalized tables to build a universe? Any documents with some examples for this?
Any expected difficulties during design/development phase of our universe, related to using normalized tables?
Any expected performance degradation if we use normalized tables compared to using dimensional tables?
Can I build universe more easily if I transform (modify) our normalized model (by using alias tables and views) to look like snowflake model?
I’m using BOE XI 3.1, tables are in Oracle 11.2.
Thank you

Few Disadvantages that I usually face when building universe on Normalized tables,
1. Performance - Read operations have to suffer because indexing strategies do not go well with table joins
2. Derived Tables - Due to complex Queries/ Logic, most of the time, end-up creating derived tables, which doesn't use back-end table indexes and slows down the report runtime.
3. Normalized table/ Transaction tables may not always have proper cardinality and often results in Cartesian products
4. Normalized tables may not have tight referential integrity and may have to join more than one column and join on varchar, etc whereas, good Dimensional model datawarehouse will have proper keys/ integer joins and not always necessary to join on multiple fields
5. Often deal with Fan and Chasm Traps
6. Dealing with Database fields with nulls, blanks, date in numeric format, etc.,
7. No Facts, Dimensions separated and most of the time they are in same table
and More...
If performance is not a matter and building Datawarehouse is a big deal, then I will start building Universe on normalized tables by having the database diagram as reference for Joins, contexts, etc
Note: After dealing with universes based on normalized tables for few years (by creating views, complex sql queries data loading to tables and unv on these tables, derived tables), I ended up creating star-schema dimensional model (couple of months extra ETL work), users/ developers felt lot better when they have to create standard/ ad-hoc reports and they are super fast compared to previous universes.

Sql Loader Vs External table? Which one is preffered?

Hello guru,
We trying to load the data into about 160 tables. Here are the following things we are doing currently,
1. We get the flat file in .txt format
2. We are writing the control file for each flat file for thier respective tables
3.And we are using sql loader command to load this data into the table.
I was wondering if this process is cumbersome, and i m not sure if external table could be simple in loading the tables compared to what we are doing ?And i have not used external tables, so wanted to know which on eis better ? So any idea is greatly appriciated !
FYI.. Version :- Oracle 11g
Thank you so much!

Thanks for you reply justin !

    revenue      NUMBER,
    CONSTRAINT revenue_pk PRIMARY KEY (person,month));
INSERT INTO revenue (person,month,revenue)
   SELECT person,'Jan',rev_jan
   FROM revext--but currently we are using sql loader, our data looks like this
1119Smith      01/01/1982AXYZ corporation xyz corp
1111collen      01/01/1990AABC corporation abc corp
     and control file is like this
INTO TABLE "XYZ_tbl"
   ID                     POSITION(01:05)        CHAR                  "DECODE(RTRIM(:ID), NULL, 'NA', :ID)"       ,
   Name                POSITION(06:15)        CHAR                  "DECODE(RTRIM(:NAME), NULL, 'NA', :Name)"   ,
   Act_dt              POSITION(16:25)        DATE                  "MM/DD/YYYY" NULLIF ACT_DT=BLANKS
My question is, can i use the options like NULLIF/ DECODE or changing datatypes when loading or functions like REPLACE / TO_DATE in External tables ? Any idea? Any example code or SQL will great
Thank you so much!

Set operations on Internal tables.

Hi,
Last week i had to enhance a program that has a internal table with some records. I need to find populate a table with the records in the internal table. But before populating i must find out the difference in the records (i.e) the extra records in the internal table compared with the records in the database table and then i have to append those records in the internal table again and then insert the internal table records into database table. while doing it i need to create another internal table with records in database table and then loop at it to find the extra records and rest of the logic goes on.
At this point of time it clicked in my mind "WHY DON'T WE HAVE SET OPERATIONS ON TWO INTERNAL TABELS(UNION, INTERSECTION, MINUS)".
Now i am doing some study how to implemnt it. Before that i want to find out whether that functionality exists in ABAP or anybody of youo gurus have done similar work on it.
Pls help me in proceeding with my work.

Hi Arul,
There is no special aided SET operations upon internal tables in ABAP. Concerning your particular task I would say that you can try INSERT statement for each record in your internal table without preliminary comparing them with DB table. If there is a record in DB table with the same key then sy-subrc after INSERT will be non zero (actually 4) and no real insert would occur. So, only those records would be inserted which have no counterpart in DB table.
Best regards, Sergei
