Need help in creating procedure
Hi all,
Can some body please help me in creating a procedure.
I have a table "NAMES" and the columns as LNAME, FNAME, EMPID
now I have a sequence EMPID_SEQ.
I have the data like
LNAME FNAME EMPID
JOHN SMITH
JOHN SMITH
PETER PARKER
MIKE JONES
MIKE JONES
MIKE JONESNow I want to write a procedure in order to give a number(EMPID_SEQ.NEXTVAL) for same first and last names like
LNAME FNAME EMPID
JOHN SMITH 1
JOHN SMITH 1
PETER PARKER 2
MIKE JONES 3
MIKE JONES 3
MIKE JONES 3can anybody please help me in writing this procedure.
Thanks in advance.
Better to use SQL
merge INTO test_tab t USING
SELECT
lname,
fname,
rownum rn
FROM
SELECT DISTINCT
fname,
lname
FROM
test_tab
s ON
t.lname = s.lname AND t.fname = s.fname
WHEN matched THEN
UPDATE
SET
empid = rn;Possibly that's not what the homework assignment called for, though.

Need Help to create new screen for RF Sapconsole
Hi Guru's
I'm new on RF (but some years in ABAP) since last week.
I need help to create new screens for RF (SAPLLMOB).
Can someone explain me the procedure to create screen (with ABAP code after) or perhaps someone have an exemple (simple or not) ?
I have to develop 2 new screens with really few time.
And, another subsidiary question :
how SAP can transfert information between the flash gun and the screen i have developped.
Is there some code to add to enable this functionality or it is include in SAPLLMOB on standard fields ????
It's a new strange world for me today...
Many thanks to everyone who can explain me
Alainhi,
I am facing this problem as well. Is there any reference to create the new screen?
Hope someone can help! Thanks!

Need help to create report with jpeg/gif image
Hello,
I need help with creating a form with a special jpeg/gif seal. I never done this Java. Until now, I created all forms with ansi C++ with HP escape characters to draw lines, boxs, and text. This form will contain boxes which is populated with database information read from a text file.
Since this form contains a special seal on the upper right, I don't think it can be done with old fashion ansi C++. How can I create a form with Java and create it as a simple exe to just print the form to a specified printer.
Thanks,
JohnHi,
I am creating a form with boxes (lines and text). What is special about this form is that it has an image jpeg or gif at the top right corner. Is is a state department seal. Up to this form, I had used ansi C++ and print out escape HP character to print out the lines, boxes, and text. I have no idea how to print out the image. I am new to JAVA and only 1 class in it. Is there sample code out there to create this type of form with the image? I need a starting point.
Thanks,

Hi everyone,
i'm fairly new to RAID scene and i need help for creating RAID 5 with 8 disk's.
I have HP ProLiant DL380 G6 with 8 disk's, each 500 GB.
i'm trying to create RAID 5 and to have one spare disk. I have made array from 7 disk and then create logical drive.
the last disk (8-th) i used as spare.
up to now i think i'm ok???
what confuse me is:
7 HDD X 500GB= 3500GB
after creating array i get 3200 GB, where i lose 300 GB??
after creating logical drive i get 2700 GB, where i lose 500 GB???
from 2700GB i give 150GB for system partition and for data storage i have only 2550 GB.
Why i lose 800GB??
Can someone explain me how RAID 5 works, do i create it correctly and why i lose so much space???
Is there other way to create RAID 5 without losing so much space?
Thanks you in advnce.The first 'loss' you encounter (300MB) is due to megabyte counting/rounding. A 500GB disk contains about 500.000.000 bytes. This quite a bit less than if counted properly using binary. you loose about 24288000 bytes per disk this way!
http://en.wikipedia.org/wiki/Mibibyte |
http://en.wikipedia.org/wiki/Megabyte
the second loss is due to how raid works.in raid 5 data is written to multiple disks to improve reliability. the simplies t form uses 3 disks: a write will cause half of the data to be written to disk 1, half to disk 2 and the XOR of both datahalfs to disk
3. In this scenario you will loose 33% of storage space and you can loose up to one of 3 disks.
By adding more disks, data can be spread more and the ratio available/raw will increase, or you can write aditionnal crc data and increase resliency for failures.
http://en.wikipedia.org/wiki/RAID
To check the exact algoritmes using on you RAID adapter, I would recommend contacting the vendor (or checking their support site) From your numbres, I do not think you will be able to configure RAID 5 on the same disks and having more available
space for your data.

Need help in creating multiple signature forms?

Automator gets a bit unweildy when trying to vary things outside of what the actions provide. Since you are already using an AppeScript in your workflow, might as well do the whole thing:
set baseFolder to (path to desktop) -- the location to create the folder
display dialog "Please provide a new folder name:" default answer "test"
set folderName to text returned of the result
repeat -- keep repeating until a number is returned
display dialog "How many subfolders?" default answer "5"
set theNumber to text returned of the result
try -- test the result
set theNumber to theNumber as integer
exit repeat -- success
end try
end repeat
tell application "Finder"
try -- make new folder
set newFolder to (make new folder at baseFolder with properties {name:folderName})
on error number -48 -- skip errors if the folder is already there
set newFolder to ((baseFolder as text) & folderName) as alias
end try
repeat with X from 1 to theNumber
try -- make new subfolder
make new folder at newFolder with properties {name:folderName & X}
on error number -48 -- skip errors if the folder is already there

I need help with creating PDF with Preview...
Hello
I need help with creating PDF documetns with Preview. Just a few days ago, I was able to create PDF files composed of scanned images (notes) and everything worked perfectly fine. However, today I was having trouble with it. I scanned my notebook and saved 8 images/pages in jpeg format. I did the usual routine with Preview (select all files>print>PDF>save as PDF>then save). Well this worked a few days ago, but when I tried it today, I was able to save it, but the after opening the PDF file that I have saved, only the first page was there. The other pages weren't included. I really don't see anything wrong with what I'm doing. I really need help. Any help would be greatly appreciated.I can't find it. I went into advanced and then document processing but no batch sequence is there and everything is grayed out.
EDIT: I realized that you cant do batch sequences in standard. Any other ideas? -

Need help in Creating External Tables
Hi All,
I have a flat file containing numberic data, CLOB data, and also date columns data. I have to load this flat file data into staging server table using External tables. I have to write a stored procedure in such way creating exteranl tables dynamically. My question or need help from you people is that how to define the external table to load the CLOB data from flat file.
Thanks,
SankarThe LOCATION clause of an external table specifies the file or files to be read when the table is queried. You can change it to refer to different files without dropping and recreating the table and invalidating all dependent code.
Regarding DBMS_SQL, yes you can do it the hard way if you prefer.
Good point about CLOB columns in external tables. Quite possibly they are not supported, but I would have to check the manuals and try some examples. -
All,
I have a function and a procedure in a package. The function is called by the procedure. The function returns multiple records with multiple fields in a table type. The procedure uses those values to update the database. My question is how can I get those values to update database. Need sample of code.
beloew is my package:
CREATE OR REPLACE PACKAGE "test_record2" as
type V_testre is record (
USER_ID NUMBER,
B_ID NUMBER,
A_ID NUMBER);
Type T_userInfo is table of user_Access %rowtype
index by binary_integer;
procedure get_info(userid in number);
function P_GetProfile(userid in number) return T_userInfo;
end;/
CREATE OR REPLACE PACKAGE BODY "test_record2" as
procedure get_info(userid in number) as
get_access T_userInfo;
v_userid number;
begin
get_access := P_GetProfile(v_userid);
--How to get the values from get_access to do the insert.
--Need help here!!!
--insert into test_access values get_access
end;
-- test table
function P_GetProfile(userid in number) return T_userInfo is
profile_info T_userInfo;
CURSOR c1 IS
select * from user_Access
where USER_ID = userid;
BEGIN
OPEN c1;
FETCH c1 BULK COLLECT INTO profile_info;
return profile_info;
END;
End;
--create the table
CREATE TABLE user_access (user_id NUMBER, m_id NUMBER, n_id NUMBER);
INSERT INTO user_access VALUES (1, 11, 111);
INSERT INTO user_access VALUES (1, 22, 222);
INSERT INTO user_access VALUES (1, 33, 333);
INSERT INTO user_access VALUES (2, 11, 111);
INSERT INTO user_access VALUES (2, 22, 222);
INSERT INTO user_access VALUES (2, 33, 333);CALL is not valid PL/SQL. (In fact, it's only valid in OLAP).
You want either...
BEGIN
test_record2.get_info(1);
END;
/...or (in SQL*Plus)....
EXEC test_record2.get_info(1)I commend the documentation to you.
Cheers, APC -
Need help in Creating a sequence
Hi,
I need to create a sequence which starts with the value one more than max value of one of the columns in a table. Can anyone help me in this regard?
Eg: I have a table 'User_Details' with one of the columns as 'ID', I need to create a sequence for this table which starts with one more the 'max(ID)' if there are any records already existing.
Thanks,
RaghuAssuming that you have some way to identify which columns of which tables will be populated by sequences in the new release, the you could write PL/SQL code to automatically generate this. In this example I have assumed that you need a sequence created forthe (single) numeric PK column of each table in a particular schema, and that the sequence name will always be table_pk_seq.
DECLARE
l_max NUMBER;
BEGIN
FOR r IN (SELECT c.table_name, cc.column_name
FROM user_constraints c, user_cons_columns cc
WHERE c.constraint_name = cc.constraint_name and
c.constraint_type = 'P') LOOP
EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM '||r.table_name INTO l_max;
l_max := l_max + 100; --just to be safe
EXECUTE IMMEDIATE 'CREATE SEQUENCE 'r.table_name||'_pk_seq '||
'START WITH '||l_max||' INCREMENT BY 1';
END LOOP;
END;John
