Retrieve all column data of a table along with the number of records received
hi, i want to select all the records from a table along with the number of records received as i need to use that number in a loop to retrive data from another table
can i use
SELECT @emp_id=emp_ID, @emp_NAME=emp_NAME,@RowCnt = (select count(*) from emp_id) order by emp_id
i tried your idea, i get error in at the over() . I am using sql compact edition and i guess it is not supporting over() function. But i am still going to use the code for example something like this assuming it will work in real time with
enterprise edition. Please let me know what i am going to use is correct or not?
SELECT [EventID],[BallroomCharge], @rowcnt=count(*) Over()
FROM [testSample].[dbo].[Events]while (@rowcnt > 0)perform some request

How to get Header data into multiple times along with the Line Items
Dear All,
I have problem while mapping the Header data and line item data to the flat file structure, Header data have to repeat along with the Line item data in the flatfile.
Details is below.
Example
Header record is one
E1EDK01
E1EDKA1
Line items are two
E1EDP01
E1EDP01
I want in the flat file two records having duplicate data in the fields which is belongs to header data
Like :
Record # partner data Line item data
Record 1 : WE name1 city 00010 materialname1 156
Record 2 : WE name1 city 00020 materialname2 198
( WE name1 city - data is same in the record 1)
For this what I did is I mapped the node E1EDP01 to the flat file message type node then I got all the line item data and first record is with header data but not in the second record.
I tried all node functions but no result because Idoc itself header data exists one record, I am not able to copy.
If any one knows , please give solution.
It is great help to me.
Thanks in Advance.

Unique file name to be decoded and to be updated in a table along with data
Hi
I'm working on a File to Proxy scenario, where the file names(10 chars length) are unique. These files will be available for XI in a source directory. My requirement is -- file name need to be decoded into 3 values and to be updated into a r/3 database table along with the file data.
Hope my requirement is clear.
Thanks.You cannot see the field which stores the file name. The file name comes from payload at runtime.
Secondly no need to create any input parametes in your UDF, just edit your udf and delete the input parameter (default input is 'a') so that you don't have to map any constant to this UDF just map this UDF to target field.
e.g. UDF ---> target Field.
I did the same but am not able to activate the mapping.

DBMS_CDC find only the columns that are changed along with the primary key in the table
Hello,
We are having a requirement to find the change data in the production environment.
We are planning to use the DBMS_CDC utility.
But for example in the create change table 1 picked emp_id,ename, address, salary,dob.
I have a sample data of
empid
ename
address
salary
DOB
1
test1
24 test street
2000
20-Jan-98
2
test2
25 test street
2500
15-Aug-97
if ename for empid 1 is changed to test1_test3 from test1.
My CDC is capturing the values in the old and new values in the 5 columns.
But i need to get only the empid (primary key of the source table) and the ename column as only that's been updated not the rest of the 3 columns.
Can i accomplish this.
Please advice.Hello,
Thanks for the information.
but if i change the change table then i will miss the other columns right?
I want to get the columns( empid and ename) only if ename is changed. i.e when ever any column in emp table changes i need to get all the columns where the data is changed along with the primary key columns empid.
Is there any way i can tweak the parameters so that i can achieve this or is there any other way using the cdc i can get this data.

Retrieve specific range data from oracle table
Hi, Dear friends,
I want to retrieve all the data from oracle table and then save them to mysql table using JDBC ResultSet. The problem is that some oracle table is too big, if I retrieve all of them to memory at a once time using excuteQuery, the program will become no response out of memory limitation. So my question is if I can retrieve just specific range data once a time. I can¡¯t find this function through JDBC API. Also, I don¡¯t want to use the specific sql sentence, for example ¡°select ¡ from¡ where someid>¡ and someid<¡¡±, because there are many different tables, I want to transfer them automatically. So I can¡¯t construct such sql sentence in advance. Does anyone know if oracle JDBC driver provide such kind of function or does there any other way?
Any suggestion will be greatly appreciated!
SammyDear Justin,
thank you so much for your prompt reply!
as your suggestion, I do check the performance while my program is running, after the program become nearly no response, I found the memory usage is nearly 100%, while disk usage and process usage is pretty low. that's the reason why I guess maybe the memory limitation, but the strange thing is that no any error reported by JBuilder, it just nearly no response and don't transfer any data any more. my os is windows xp, the version of JBuilder is 7. my main memory is 768M. just as you said, the total 6,000 records in not very large, just no more than 400K. another strange thing is that why my program works well when there is little data records in the table.
the big picture of my program is first I retrieve oracle table metadata, according to this information, I construct DDL sql words and then create the corresponding table in mysql database. this part works well. in order to save your time, I will not paste the code here. then there is a method to transfer oracle data to mysql table, whenever creating the mysql table, then I will call this method to transfer datat to it. the following is the code of this method, I am very sorry to take your time. please read it when you are available.
thank you very much!!
Sammy

Copying Long Raw Column Data to another table
hi everyone,
i am trying to Copy Long Raw Column Data to another table in the same schema. this is the situation
Table A (col1 number,col2 long raw) with 100 records
Table B (col1 number,col2 long raw) with 0 records
now i want to copy col2 of the table A into the column 2 of the table B. but long raw data cant be retrieved in a select statement so is there any specific procedure that will copy long raw data or there is any simple way.
i will be really grateful for anybody's help.
thanx
shakeelDust off that old SQL*PLUS command "COPY" ...
create table tablea (col1 number,col2 long raw)
insert into tablea values (1, testrawio.chartoraw('this is line one'));
insert into tablea values (2, testrawio.chartoraw('this is line two'));
insert into tablea values (3, testrawio.chartoraw('this is line three'));
create table tableb (col1 number,col2 long raw)
copy from scott/tiger@larry insert tableb (col1, col2) using select col1, col2 from tablea
Array fetch/bind size is 15. (arraysize is 15)
Will commit when done. (copycommit is 0)
Maximum long size is 80. (long is 80)
3 rows selected from scott@tiger.
3 rows inserted into TABLEB.
3 rows committed into TABLEB at DEFAULT HOST connection.
SQL>Now to prove it has worked :
begin
for lr in (select col1, col2 from tableb)
loop
dbms_output.put_line('col1 = '||lr.col1||
' and col2 contains long raw equivalent of '||testrawio.rawtochar(lr.col2));
end loop;
end;
col1 = 1 and col2 contains long raw equivalent of this is line one
col1 = 2 and col2 contains long raw equivalent of this is line two
col1 = 3 and col2 contains long raw equivalent of this is line three
PL/SQL procedure successfully completed.

Data Display table along with Graph
As per my knowledge we are not having any option currently for displaying data table along with graph.
This plot data table can have plot name along with current data.
See the sample below. Many times I need to display number of parameters on graph and current value need to see along with graph.
It will very useful if I get something like this in next version.Hi chameli,
well, you gave the chart as an example to your question - but didn't specify your question any further!
What's wrong with a little coding to have your data presented as you like to?

If you never synced your phone to your computer and your contacts were not synced to iCloud or another cloud-based service, everything is gone. You will have to start fro scratch.

Copying tables along with their indexes between databases
I use sql server management studio express. I have a database that has some questionable schemas, roles, etc, so I decided to create a new database, with just tables, stored procedures, and user-functions.
So I used the "import data" feature, which allowed me to select several tables, that were copied along with their data.
Then, I scripted out all the user-functions and stored procedures from the original database, and pasted them into a query window for the new database, and executed the create statements for each.
Then I got a message that I was lacking a full-text index.
I then started examining some tables, and even regular tables with an integer primary key that is supposed to be an identity' field were not identity fields any more, and lacked the auto-increment.
I tried to change that, and make them auto-increment, and then sql server told me that I can't do that. I guess if there is already data inside an integer field, you can't make it auto-increment.
So how do I solve all this?
ThanksYou cant modify a column to be of type identity. For that you need to do the below
http://www.mssqltips.com/sqlservertip/1397/add-or-drop-identity-property-for-an-existing-sql-server-column/
But in your case what works best would be to script out the table along with identity and then use it to create the table in the new database.

Kind Regards,
Shanbagavalli.SHi 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.
