Common records from two recordset

Hi All,
I have a problem.Consider two recordsets A and B. I want
common records that are present in both A and B . Is there any easy
way to do this? Please help me out!!!!

same principle:
<cfquery name="myQoQ" DBTYPE="query">
SELECT *
FROM query1, query2, query3
WHERE query1.somecolumn = query2.somecolumn
AND query1.somecolumn = query3.somecolumn
</cfquery>
but... unless your different queries query different
databases (as
opposed to different tables in the same db), it is better to
just use 1
(one) query to select all your data.
if you post you queries' code and how the tables are related
(through
which fields), we'll help you write one query that will pull
just the
data you need... unless you do use the queries individually
in your code
somewhere (i.e. you do need to use full recordset of all
queries
involved at some point in the page - if your queries are just
for
creating a QoQ, then you definitely better changing your 3
queries into
1 query!)

I do not see a way to separate audio channels to edit them separately in Premiere Elements (any version).
Premiere Elements does have audio effects including Balance, Fill Right/Fill Left, and Swap channels, but that is not what you are seeking.
I would refer you to an audio editor such as the free Audacity for what you want to do.

But, the opportunity seems to be in Premiere Pro, not Premiere Elements
Please review and consider and then let me your thinking on the matter relating to your Premiere Elements 12 (what operating system).

Find if there is any common record in two internal tables

hi,
I have two internal tables of same structure... say A and B.
I need to know if there are any common lines in them.
one way is to loop in any one of them and keep executing a read on the other.
can anyone suggest a better way.
thanks,
Arindam.

Hi Arindam,
To find common records in two internal tables, they can be compared
If INT_DATA1 EQ INT_DATA2.
endif.
The first criterion for comparing internal tables is the number of lines they contain. If two internal tables contain the same number of lines, they are compared line by line, component by component.
If the internal tables contain the same number of records and are sorted on the same key, the comparison stops at the line where the records are not common. For example, if the number of common records is 4, the comparison stops at the 5th line and sy-tabix becomes 5.
Hope it helps.

How to handle an update of the same record from two different user JSP

how do you handle an update of the same record from two different users in JSP... if one person updates the record from one drop downs should be updated as well.. is the possible.

I'm not sure whether I understand your question. If one user changes a record then you would like other users to see those changes. Normally those changes will be visible to other users when they refresh their browser, after the first user has committed changes to the record. I you want to be sure that the same row isn't updated at the same time by to different user, you need to configure some locking (pessimistic locking) - this depends of what technology you use. In EJB3 pessimistic locking is performed by adding a version to every entity object. If you are using ADF, the framework is able to handle either pessimistic or even optimistic locking.
If you want the changed row to be updated in other users browsers without any user interaction by these users, you should take a look at Reverse Ajax (ex. DWR http://ajaxian.com/archives/reverse-ajax-with-dwr) - or Ajax in general. But you will never get a realtime solution, where changes is visible in other users browsers right after each record update.

how to handle an update of the same record from two different user
how do you handle an update of the same record from two different users in JSP... if one person updates the record from one drop downs should be updated as well.. is the possible.

Usually, if two users try to update the same row at the same time, you want the first to commit to succeed, and when the second commits, they should fail with the error that the row was being concurrently updated. They you may want to show them the new row values and give them the opportunity to merge their values with the new row values...
How can you achieve this? Google optimistic locking.

How to fetch records with two recordset

i want fetch records from the table using two recordset like
ResultSet r1=stmt.executeQuery("select * from pf_data");
i want to take another recodeset
ResultSet r2=stmt.executeQuery("select * from finyr");
I am using Microsoft SQL server as my database.
I am also closing the recordset like r1.close();
then i cannot take two recordset at the same time.

Hi,
This is an example of a Top-N problem, and here's one way to do it:
WITH got_r_num AS
    SELECT item_id, supp_id, rnk                         -- RANK is not a good column name
    ,       DENSE_RANK () OVER ( PARTITION BY item_id    -- Just guessing
                                 ORDER BY      rnk
                               ) AS r_num
    FROM    table_x
    WHERE   item_id = 2      -- If desired
SELECT    item_id, supp_id. rnk
FROM      got_r_num
WHERE     r_num    <= 2
RANK is the name of a built-in function in Oracle, so it will cause lots of trouble if you use it as a column name. (The RANK function is closely related to DENSE_RANK, used above.)
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Point out where the query above is giving the wrong results, and explain, using specific examples, how you get the correct results from the given data in those places. If you changed the query at all, post your code.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

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.

SELECTing records from two tables. Set Operators, CASE, DECODE, ...

Hi all,
I have two tables:
CRETE TABLE T1 (T1_COL1 NUMBER, T1_COL2 NUMBER)
CRETE TABLE T2 (T2_COL1 NUMBER, T2_COL2 NUMBER)
T1 may or may not have records. T2 always has records. There are two scenarios.
Scenario 1:
=======
SELECT * FROM T1 returns five rows, and SELECT * FROM T2 returns 10 rows.
Now I need the five rows from T1.
Scenario 2:
=======
SELECT * FROM T1 returns zero rows, and SELECT * FROM T2 returns 10 rows.
Now I need the 10 rows from T2.
In other words, if records present in T1, I need them all. If not, I need records from T2.
There are no common columns (for joins).
Now need a single query to achive this. I tried set operators, CASE and DECODE. But I'm unable to solve it.
Please help. Thanks in advance.

Is there any other way, which is simpler, without using RANK?That's the simplest option I can think of. You could also do something like

Hardware needed to record from two HD sources

Hi. I'm a researcher studying social interactions in children with autism. I would like to capture compressed HD video from two sources simultaneously using a mac mini and with real-time output to two monitors. The reading I've done so far indicates the new mac minis can output to two different monitors simultaneously. In addition, I have identified one piece of software that seems capable of recording and monitoring two streams at the same time (bigmugsoftware.com) but I'm open to other alternatives (i.e., does Final Cut do this?).
My bigger problem is identifying precisely what hardware will be necessary to do this. I'm imagining capturing compressed, not raw, HD video. So, video might come from a camcorder via USB or component input (not HDMI). But, the program from bigmugsoftware requires a firewire connection and I haven't been able to find even one HD camcorder with a firewire port.
There also seem to be products like the Grass Valley TwinPact100 Video Converter. But, it's not even remotely clear if two of these can work on the same computer at the same time.
Any help would be appreciated.

I haven't been able to find even one HD camcorder with a firewire port.
Any mini DV or HDV camera will have firewire.
There's still plenty available.

Can i select Records from two tables into an itab.

Hi,
    Suppose that i have two tables spfli and sflight.
    Now i want the records from both the tables into a single internal table.
    If so please let me know how this can be done.
    itab should consist of all the columns in sflight and spfli.
Regards,
Sai

Sai,
Yes u can do it using JOINs.
Use this link for ref
http://www.sap-img.com/abap/inner-joins.htm
INNER JOIN results are an intersection of the tables being joined where in only if both the tables havethe data the result is pused onto the result set.
WHERE as in LEFT OUTR JOIN you can push the data of the LEF T table on the resultset even when the join condition is not met.
The use is that you wantto have all the data that is there in left table and also the right table if the join condition is a success then right table fileds will have data else they are initial.
OUTJOIN's are used in MAINTENANNCE VIEWS, HELP VIEWS .
INNER JOINS are used DATABSE VIEWS.
Inner Join:-
SELECT pcarrid pconnid ffldate bbookid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( spfli AS p
INNER JOIN sflight AS f ON pcarrid = fcarrid AND
pconnid = fconnid )
INNER JOIN sbook AS b ON bcarrid = fcarrid AND
bconnid = fconnid AND
bfldate = ffldate )
WHERE p~cityfrom = 'FRANKFURT' AND
p~cityto = 'NEW YORK' AND
fseatsmax > fseatsocc.
Left Outer Join
SELECT scarrid scarrname p~connid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM scarr AS s
LEFT OUTER JOIN spfli AS p ON scarrid = pcarrid AND
p~cityfrom = 'FRANKFURT'.

Pick Common records from 2 internal tables

Hi,
I have 2 similar internal tables it_bseg1 (contain records based on the Posting Date BUDAT of document) & it_bseg2 (contain records based on the Customer Code KUNNR). Both these tables contains some common records. And I want these common records only. So please tell me to get the common records in the easiest way.
Regards,
Vishal

Hi,
There must be atleast one common field for these two internal tables to get the common records.
If you identify the common field then you can use this logic.
Loop at it_bseg1 into wa_bseg1.
Read table bseg2 into wa_bseg2 with key <commonfield > = wa_itab1-<commonfield>.
If sy-subrc eq 0.
Append wa_bseg1 to it_bseg3.
Endif.
Endloop.
Now it_bseg3 contains the common records.
If there is no use of it_bseg1 in your further development then you can do teh logic without declaring third internal table it_bseg3.
Loop at it_bseg1 into wa_bseg1.
Read table bseg2 into wa_bseg2 with key <commonfield > = wa_itab1-<commonfield>.
If sy-subrc ne 0.
delete it_bseg1 where <commonfield> = wa_itab1-<commonfield>.
Endif.
Endloop.
Now it_bseg1 contains teh common records of it_bseg1 and it_bseg2.
Hope this will help.

How do I extract matching records from two tables?

I'm trying to extract client records from our client database to put together a very targeted email campaign. As an example, the result I want is a list of names and email addresses of those clients who have a record in our system, have not had a visit in our clinic in the last year, and live within 200 miles of our clinic. I can capture the first two criteria in one extract, and the second in another. I can then import those as tab delimited data into Numbers. What I then need to do is create a third table that represents ONLY those records that exist in both tables.
Can someone tell me if this is possible and if so, how to do it?
I'd be very appreciative of any help, thank you.

You can create a column that generates a serial marker on the table from which you want to transfer the data, making all the names that also appear on the other table. Not that the formula will mark only exact matches.
Here's a short example:
Table 1 on the left, is one of the two tables imported from the tab delimited data files. It has other data, but only the names in column A are used to identify records appearing on both tables.
Table 2 on the right, contains the names and other data (represented by the email addresses in column B), to be transferred to the third table.
Column C of this table contains the formula that counts off the rows containing names appearing on both tables. The version below is in C2, and is filled down to the end of the column.
=IF(COUNTIF(Table 1 :: $B,A2)>0,MAX($C$1:C1)+1,"")
Note that jane Doe is not counted (or transferred) as her name is recorded differently on the two tables.
Table 3 is the results table. It contains one formula for each column to be transferred from Table 2 to Table 3.
A2: =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $A))
B2: =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $B))
Regards,
Barry
EDIT: I was working in Numbers '09 when developing this, and got the following warning when I saved a copy as an iWork '08 document:
Referencing row or column ranges that include header or footer cells isn't supported. The formula references were updated to exclude header and footer cells.
The formulas in Table 2::C2 references C1. You may have to ensure that Table 2 does not include a header row.
B.
EDIT2: A check on the file in Numbers '08 showed no apparent change to the formula, and editing Jane Doe's name on table 1 resulted in her name being added to Table 3.

r you trying to do something like below ?
Delete from TableA A
where not exists (select 1 from TableB B where
A.keyA_id=B.keyA_id and
A.keyB_id=B.keyB_id and
A.keyC_id=B.keyC_id and
A.keyD_id=B.keyD_id)

Ordering dated data from two recordsets?

So I have two different recordsets (two different databases,
two different
connection strings) being retrieved into an ASP/VBScript
page, and both
tables contain dated data.. and I need to combine both
recordsets into one
list.. can anyone point me to a clue as to how to handle
this???

I have done a logical fact table with two fact table source on it.
The Sql performed against the database was this one.
-------------------- Sending query to database named PRODS_AIX (id: <<153418>>):
WITH
SAWITH0 AS (select sum(T21296.CONSUMERS_SALES_EURO) as c1,
     T21309.DIVISION_CODE as c2
from
     DIVISION T21309,
     C_CONSUMERS_SALES T21296
where ( T21296.DIVISION = T21309.DIMENSION_KEY )
group by T21309.DIVISION_CODE),
SAWITH1 AS (select sum(T21356.ORDER_VALUE) as c1,
     T21309.DIVISION_CODE as c2
from
     DIVISION T21309,
     DWH_SALES_ORDER_OVERVIEW T21356
where ( T21309.DIMENSION_KEY = T21356.DIVISION_KEY )
group by T21309.DIVISION_CODE)
select distinct case when SAWITH0.c2 is not null then SAWITH0.c2 when SAWITH1.c2 is not null then SAWITH1.c2 end as c1,
     SAWITH0.c1 as c2,
     SAWITH1.c1 as c3
from
     SAWITH0 full outer join SAWITH1 On nvl(SAWITH0.c2 , 'q') = nvl(SAWITH1.c2 , 'q') and nvl(SAWITH0.c2 , 'z') = nvl(SAWITH1.c2 , 'z')
order by c1As you can see one select (SAWITH0) for the first fact table C_CONSUMERS_SALES and one select for the second fact table DWH_SALES_ORDER_OVERVIEW (SAWITH1 ) and the two statement are joined with a full outer join.
I ask me why you have the three select (SAWITH0,SAWITH1 and SAWITH2). Can you please paste the complete SQL performed ?
Can you tell us also which SQL is performed if you select only the columns from one fact table and not for the other ?
