Use User_tab_cols view to extract the result.
Try
SQL> create table test3(id number(10),name varchar2(10));
Table created.
SQL> create table test4(id number(20),addr varchar2(200));
Table created.Now query user_tab_cols
SQL> select column_name from user_tab_cols where table_name='TEST3'
2 intersect
3 select column_name from user_tab_cols where table_name='TEST4'
4 /
COLUMN_NAME

How to use common object from two tables with out join.

HI,
I have two tables called A & B In A table i have the following objects
1.weekend
2.S1(measure)
3.S2(measure)
4.S3(measure)
5.S4(measure)
And In B table i have followning columns
1.week end
2.p1(measure)
3.p2(measure)
4.p3(measure)
5.p4(measure)
Now in universe i created all the measure objects i.e.s1,s2,s3,s4,p1,p2,p3,p4 A.weekend,B.weekend.
instead of using week end two times i wnt to use only once because this is common in both table.
if i use join between these tables i am getting values fine
But With out join is there any thing to do in universe level to create common objects to use from both the tables..I tried using aggregate awareness but while reporting it is taking as two SQL.which is not synchronized.
Please help me on this ...

hi,
Although Weekend column is present in both tables, by creating a single Object in Universe, Universe can identify relationship with only table referenced in Object Creation.
So, there will be no identification of relationship with other table measures.
Obviously, you need to create 2 Weekend objects in Universe (in two classes).
Case 1: You need not join these two tables in Universe. When you create 2 Queries in WEBI, automatcially Weekend objects are synchronized (if both are of same datatype)
Case 2: If you join these two tables in Universe, Obviously,
your SQL may contain Weekend from Table1, measures from Table 2
or
your SQL may contain Weekend from Table2, measures from Table 1
Finally, You need to create 2 objects in Universe. But your query may contain a single Object based on Case 2.

How to find common fields between two tables

Hi friends,
Is there any way to find out common fields between tables and linking the tables based on common fields.
Thanks and Regards,
Chitty.

Hi Chitty,
Try using joins it will give the fields which are only common to both the fields.
Here s an example,
SELECT mara~matnr
       marc~werks
INTO   TABLE t_material
FROM   mara AS mara INNER JOIN marc AS marc
ON     maramatnr = marcmatnr
WHERE mara~mtart = p_mtart.

Selecting columns from two table is slow but same

I am selecting 27 columns from two tables
which running for more than 30 minutes. but
if I select count(*) with the same query
except the columns it is coming in seconds.
Where is the error?

If you post
1) The table definitions for the underlying tables
2) The indexes that are on the tables
3) The two SQL statements you're running
4) The explain plan for both statements
we can probably be of some assistance.
My guess is that the count(*) is able to return much more quickly because the optimizer is able to use a significantly faster query plan that is based on an index which the longer-running query cannot utilize. Without the information I've requested, though, it's hard to do more than speculate.

How to find diffrence in columns from two tables

Hello,
I have table TABLE1 and TABLE2 with same columns. One of the columns in both tables is ID
Now there are records in table TABLE1 with ID=1
and in table TABLE 2 with ID=-1
Now I want to find if there are any column differing in values in tables TABLE1 for ID=1(for TABLE1) and TABLE2 for ID = -1 (for TABLE2)
What is the best way to find the diffrence?
Thanks in advance.

Hello Subhash,
Why don't you try NOT EXISTS functionality? Its quite performance effective too.
select * from table1
where NOT EXISTS
(select 1 from table 2
where table1.ID = table2.ID)
UNION
select * from table2
where NOT EXISTS
(select 1 from table 2
where table1.ID = table2.ID)You can go for UNION if required, or else you can use them separately.

How to get common datas from two int.tables

hi,
please tell me , how to i will get the common datas between two int. tables
& place them in third int. table.
give me syntax.
regards
subhasis.

Hi Subhasis,
<b>SORT :</b></u>
SORT itab.
Extras:
1. ... BY f1 f2 ... fn
2. ... ASCENDING
3. ... DESCENDING
4. ... AS TEXT
5. ... STABLE
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Field symbols not allowed as sort criterion.
Effect
The entries in the internal table are sorted in ascending order using the key from the table definition (DATA, TYPES).
Addition 1
... BY f1 f2 ... fn
Effect
Uses the sort key defined by the sub-fields f1, f2, ..., fn of the table itab instead of the table key. The fields can be of any type; even number fields and tables are allowed.
You can also specify the sort fields dynamically in the form (name). If name is blank at runtime, the sort field is ignored. If itab is a table with a header line, you can also use a field symbol pointing to the header line of itab as a dynamic sort criterion. A field symbol that is not assigned is ignored. If a field symbol is assigned, but does not point to the header line of the internal table, a runtime error occurs.
If the line type of the internal table contains object reference variables as components, or the entire line type is a reference variable, you can use the attributes of the object to which a reference is pointing in a line as sort criteria (see Attributes of Objects as the Key of an Internal Table.
You can address the entire line of an internal table as the key using the pseudocomponent TABLE_LINE. This is particularly relevant for tables with a non-structured line type when you want to address the whole line as the key of the table (see also Pseudocomponent TABLE_LINE With Internal Tables).
If you use one of the additions 2 to 5 before BY, it applies to all fields of the sort key by default. You can also specify these additions after each individual sort field f1, f2, ..., fn. For each key field, this defines an individual sort rule which overrides the default.
Addition 2
... ASCENDING
Effect
Sorts in ascending order. This is also the default if no sort order is specified directly after SORT. For this reason, it is not necessary to specify ASCENDING explicitly as the default sort order.
With the addition BY, you can also specify ASCENDING directly after a sort field to define ascending order explicitly as the sort sequence for this field.
Addition 3
... DESCENDING
Effect
Sorts in descending order. If the addition comes right after SORT, DESCENDING is taken as the default for all fields of the sort key.
With the addition BY, you can also specify DESCENDING directly after a sort field.
Addition 4
... AS TEXT
Effect
Text fields are sorted appropriate to the locale. This means that the relative order of characters is defined according to the text environment being used.
When an internal mode is opened (in other words, when a roll area is opened), the text environment is automatically set to the logon language specified in the user master record. If necessary, however, you can change the text environment explicitly in your program by using a SET-LOCALE statement.
If the addition comes directly after itab, locale-specific rules are used for all fields of the sort key where the type of these fields is C or W. After the sort, the sequence of entries usually does not match the sequence which results otherwise, without using the addition AS TEXT, i.e. with binary sorting.
With the addition BY, you can also specify AS TEXT directly after a sort field, provided it is of type C or W, or a structured type. Otherwise, a runtime error occurs. In sort fields with a structured type, AS TEXT only affects subcomponents with type C or W.
In case of an invalid character, a SYSLOG message is written, and the respective record is inserted at the end.
Note
Please keep the rules for site-specific sorting in mind.
Example
Sort a name table with different keys:
TYPES: BEGIN OF PERSON_TYPE,
         NAME(10)   TYPE C,
         AGE        TYPE I,
         COUNTRY(3) TYPE C,
       END OF PERSON_TYPE.
DATA: PERSON TYPE STANDARD TABLE OF PERSON_TYPE WITH
                  NON-UNIQUE DEFAULT KEY INITIAL SIZE 5,
      WA_PERSON TYPE PERSON_TYPE.
WA_PERSON-NAME    = 'Muller'. WA_PERSON-AGE = 22.
WA_PERSON-COUNTRY = 'USA'.
APPEND WA_PERSON TO PERSON.
WA_PERSON-NAME    = 'Moller'. WA_PERSON-AGE = 25.
WA_PERSON-COUNTRY = 'FRG'.
APPEND WA_PERSON TO PERSON.
WA_PERSON-NAME    = 'Möller'. WA_PERSON-AGE = 22.
WA_PERSON-COUNTRY = 'USA'.
APPEND WA_PERSON TO PERSON.
WA_PERSON-NAME    = 'Miller'. WA_PERSON-AGE = 23.
WA_PERSON-COUNTRY = 'USA'.
APPEND WA_PERSON TO PERSON.
SORT PERSON.
Now, the sequence of the table entries is as follows:
Miller 23 USA
Moller 25 FRG
Muller 22 USA
Möller 22 USA
If, for example, you apply German sort rules where the umlaut comes directly after the letter 'o' in the sort, the data record beginning with 'Möller' would not be in the right place in this sequence. It should come second.
Provided a German-language locale is set (e.g. sorting is according to German grammatical rules, see also SET LOCALE), you can sort the names according to German rules as follows:
SORT PERSON BY NAME AS TEXT.
Now, the sequence of table entries is as follows:
Miller 23 USA
Moller 25 FRG
Möller 22 USA
Muller 22 USA
Further examples:
SORT PERSON DESCENDING BY COUNTRY AGE NAME.
Now, the sequence of table entries is as follows:
Miller 23 USA
Möller 22 USA
Muller 22 USA
Moller 25 FRG
SORT PERSON DESCENDING BY AGE ASCENDING NAME AS TEXT.
Now, the sequence of table entries is as follows:
Muller 22 USA
Möller 22 USA
Miller 23 USA
Moller 25 FRG
Addition 5
... STABLE
Effect
Uses a stable sort, that is, the relative sequence of entries that have the same sort key remains unchanged.
Unlike additions 2 to 4, you cannot use this addition directly after a sort field.
Notes
General:
The number of sort fields is restricted to 250.
The sort process is only stable if you use the STABLE addition. Otherwise, a predefined sequence of fields used to sort a list is not usually retained.
It does not make sense to use the SORT command for a SORTED TABLE. If the table type is statically declared, the system returns a syntax error if you try to SORT the table. If the table type is not statically declared (for example, because the table was passed to a FORM routine as an INDEX TABLE in a parameter), and the system can interpret the SORT statement as an empty operation, it ignores the statement. This is the case when the key in the BY clause corresponds to the beginning of the table key. Otherwise, a runtime error occurs.
To delete all duplicate entries from a sorted internal table (e.g. just after SORT), you can use the DELETE ADJACENT DUPLICATES FROM itab statement.
When using the addition AS TEXT, the sequence of entries after the sort does not usually match the sequence resulting from a binary sort, i.e. if the addition AS TEXT is not specified. The consequence of this is that after the SORT, you are not allowed to access with the READ TABLE itab ... BINARY SEARCH statement.
If you still want to access data sorted apppropriate to the locale with a binary search, you can do this by including an additional component in the table where you can explictly store the data formatted using the CONVERT TEXT ... INTO SORTABLE CODE statement. This is also recommended for performance reasons if you have to re-sort the table several times according to locale-specific criteria.
If the internal table has more than 2^19 lines or is larger than 12 MB, the system sorts it physically using an external auxiliary file. You can specify the directory in which the file should be created using the SAP profile parameter DIR_SORTTMP. By default, the system uses the SAP data directory (SAP profile parameter DIR_DATA).
Notes
Performance:
The runtime required to sort an internal table increases with the number of entries and the length of the sort key.
Sorting an internal table with 100 entries with a 50 byte key requires about 1300 msn (standardized microseconds). Using a 30-byte key, the runtime is about 950 msn.
If one of the specified sort criteria is itself an internal table, SORT may sometimes take much longer.
The runtime increases if you use a stable sort.
Physical sorting reduces the runtime required for subsequent sequential processing.
Reward If Useful.

Chitra

How to find a column name in tables

Hello Guys,
I need to find a column name "company_id"
in all the tables in my schema. How can i dont this?
Is there any view that search for coulmns in a table. Please help.
Regards, Imran

Questions about the dictionary are best answered by querying DICT.
In this case
select * from dict where table_name like '%COL%'
Alternatively you can look in the Oracle reference manual for your version.
The information is online, there is little need to ask around here.

Display columns from two tables without making join

Hi,
I need to perform currency conversion in the report.
For eg:) Whatever the currency in ar_payment_schedules i want to
convert it to INR equivalent.
Following is the query to do this.
select ps.invoice_currency_code Currency_B,
     decode(ps.invoice_currency_code, 'INR',ps.amount_due_original,
               round(ps.amount_due_original*
                              ps.exchange_rate,
                         curr.precision)
     from
          ar_payment_schedules     ps,
          fnd_currencies          curr
     where ps.customer_id          = '111'
     and curr.currency_code      = 'INR'
When i do this in the Administration tool, the answers modules erroring out saying
that no joins between ar_payment_schedules and fnd_currencies. But here join is
not needed becuase fnd_currencies is filtered with INR and will return only
one row. Without joining two tables how can i get the same results in Answers.
thanks,
Prasanna

If it would return only one row then what is the need for the join (is it just for returning the precision?). Cant you just hard code the precision value instead of getting it from the table? Also you are doing a cartesian join, though the filters would take care of the final output this would result in a bad performance as your data starts scaling out. You need to find a key to join these 2 tables. If you do not have one, then just create a view with the cartesian join alone and then use that in your report.
Thanks,
Venkat

Selecting a common column from multiple tables

hi All.
can you guys advice a best way of doing the following
i have 60 table sin a schema 30 with a and 30 with b
all this 60 tables have a common column Load_dt
how can i get
tablename,count(records),max(load_dt) from all the tables

declare
    max_dt some_table.load-dt%type;
    cnt_recs pls_integer;
begin
    for lrec in ( select table_name from user_tab_columns where column_name = 'LOAD_DT' )
    loop
        execute immediate 'select count(*), max(load_dt) from '||lrec.table_name
              into cnt_recs, max_dt;
        dbms_output.put_line(lrec.table_name||' has '||cnt_recs||' records, max_load_dt='||max_dt);
    end loop;
end;
/you may want/need to apply a format mask in a TO_CHAR() call on max_dt.
There are other approaches to getting the data out - it depends on how you want to process it subsequently.

burgess 45 ngm
if u observe the above two tables data you can easily identify there is repeated data/duplicated data in both tables.
as there any way find out using comparison same records in two tables..........
if i write a query then i can easily understand the same data is existed in two tables
Thanks in advance....

So, what is your problem now?
You can join both the tables using a simple query and get the records.
select e1.empname, e2. empname from emp1 e1, emp2 e2 where
e1.empname = e2.empname and e1.empid = e2.empid
