using nvl2 and decoding

Hi Experts,
Here, my requirement is if column values is null or zero IT must go to zero if it is to have a value, it must pass value + concat a symbol '%'.

I tried something like this

Select nvl2 (year, concat (year, '%'), 0) in the sale

It manages only null values, when I train with Decode I get ora-01722 error.

someone can help me.

Thank you
KSS.

OK, try:

select CASE WHEN NVL(year,'0') = '0' THEN '0' ELSE concat(year,'%') END val
  FROM SALES;

Or:

select CASE WHEN NVL(year,0) = 0 THEN '0' ELSE concat(TO_CHAR(year),'%') END val
  FROM SALES;

You should post your data types too.

memory encoding and decoding

Hi, I'm working on the project now.

I use a program that someone else created and change to the new PDA device that is enough for us.

I need to understand how the programmer coded the old way for me so to unstanding how interpetted the code registers 8 memory.

well, from stractch...

This give PDA code 8 memory registers...

I think they are hex and his converts to binary.

There are 26 bits...

the code I will attach take these bits and decode out them...

I don't understand what is happening in this code, so I was hoping that someone can help me by disabling things for.

Propably you can connect the inputs/outputs (or read/write for the globals) of the vi decodeing and then boning with these data.

Base64 encode and decode

Hello

I use opennssl for encoding and decoding base 64 and face to face some of the question, he refuses to randomly to encode or decode, to give me a result of 0 and not false BIO_SHOULD_RETRY... I'm trying to put the call in a while if return 0, but it does not work and so I can not decode or encode more...

The code I am using:

uint8_t* Tools::base64(uint8_t *input,  uint32_t length)

    bool done = false;
    int res = 0;
    while(!done)

If you look at the data, some fields have a lot of * and some af a bit such as *. I want to load data into a table, and when a field contains all * as the value, I want to set to null. If a field contains a * and alphanumeric, so this value should be as it is.

in the above example, * must be set to null and * should also be defined with a null value. Note that there is a field with x as this area contain alpha numeric, it must be loaded into the table, as is. the only time in field must be set to null, it's when the value contains all .

someone in this forum suggest using to decode, but looks like it doesn't work and I get error when it reads the second field and try to insert into the column number a2.

is it possible to use regular expressions to find out if a field contains all *. I also want to cut each field as they may contain spaces.
can be a help for this, use the ctl sqlloader and above?
You can include regular expressions in you SQL * file the charger control.

An example can be found here:

Is it possible to send a picture using NetStream and NetConnection?

Would I be able to send an image using NetStream and NetConnection?

Hi mattbanks82 ,

I have not actually tried this before, but I think it can work if you can somehow encode the image as a byte array and send it, and then it receives, you can decode the byte array. There is an as part of the AS3 core lib project http://code.google.com/p/as3corelib/ JPEGEncoder class work that can encode a JPEG image in byte array, but I'm not really sure if it will serve your purpose. Maybe you can consult the documentation for the class to see if it suits your purpose. Otherwise you can consider implementing your own encoder.

Thank you

SQL Loader: Help TRIM and Decode functions please
Hello

I have load data from a flat file, for some columns, I need to use the TRIM and DECODE functions. It's a pipe delimited file.

I get a syntax error (one is lower) same error listed for GARNISH.

SQL * Loader-350: at line xx syntax error.
Expected ', 'or') ', found 'DECODE '.

===========
, FINAL_BILL_DATE CHAR (30) "TRIM(:FINAL_BILL_DATE)".
, BUSINESS_ID 'DECODE(:BUSINESS_ID,'B',1,'C',2,'E',3,'G',4,'O',5,'R',6,'T',7,'U',8,'H',9,-1) '.

Can someone please help.

Thank you
Josiane
Hello josiane.
The error you receive leads me to believe that at some point before the DECODING on the BUSINESS_ID line, probably some line before the FINAL_BILL_DATE line, it is a syntactic error causing the quotes before DECODING actually put an end to some other syntaxes. Without any lines that might actually contribute to this, including details of the header, it's the best I can advise.

Hope this helps,
Luke

data of cutting using substring and instring, and storage in a new table

Hi all

I have an emp_address 2tables, address as below:
---------------------------------------------------------------
create the table emp_address (emp_id varchar2 (10), address varchar2 (100));

Insert into EMP_ADDRESS
(EMP_ID, ADDRESS)
Values
('101', 'street1 fremont CA 94538');
Insert into EMP_ADDRESS
(EMP_ID, ADDRESS)
Values
("102", "Street.2 fremont, CA 94537');
COMMIT;

create the address table (emp_id varchar2 (10), street varchar2 (20), city varchar2 (15), State varchar2 (10), zip varchar2 (10));

-----------------------------------------------------------------------------
Emp_address data as below:

emp_id address

street1 101 fremont CA 94538

102 fremont, CA 94537 Street.2

------------------------------------------------------------------------------
now I read data emp_address and split the data of the address column and record these data in the address table like as below

emp_id Street City State Zip Code
street1 101 fremont, ca 94538
102 fremont, ca 94537 Street.2

-------------------------------------------------------------------

I'm trying to divide these data using substring and instring. Actually my problem was between the data a few times I have 1tab or 2tabs and sometimes 3tab. If the number of tab spaces is not constant.

So can u help me in this case.

Thanks in adavnce

That means "use work and movement? ''

When you open the window of information on an album, there is a checkbox for "use work and movement". What does that mean? Feel if you tick the box?

'Work' and 'movement' are designed for orchestral works - so does that music as Beethoven symphonies can be arranged.

The only solution is to the compress first, then it will be delivered as an attachment, allowing the recipient to decompress and open it.

I use thunderbird and firefox but not be able to get support. My credentials are not recognized.

I have been using Thunderbird and Firefox for more than 12 months and at that moment there registered for Mozilla Support. Several times during this period, I tried to connect to the Support without success due to 'details' unrecognized and as advised, my email address has been sent, so that a new password can be generated. Each time, Mozilla responded by saying that a link of e-mail had been sent to me to generate a new password. I have never received such an email from Mozilla, so I've never been able to access the media.
I guess that the apparent success today is maybe because of me go a different route to get a valuable source of information. I hope that is correct and have no role in «good luck»

Well, you're here now. I have never had such problems myself so it is difficult to know what to say about the difficulties that you had.

I do not use sync and am not connected? Why my favorites are synchronization?

My desktop computer has a series of bookmarks that I use at work. My home PC has another, different set of bookmarks that I use at home. I do not use sync and am not connected to sync on each PC. Why my favorites are the synchronization between two PCs? For example, I noticed several bookmarks near the top of my bookmark menu over a line of separation that I do not have to work. I deleted them. I come home and find those missing same bookmarks from my PC at home. I do not want to synchronize anything between the two computers, why what is happening?

Maybe an add-on is the sync these for you.

Refresh (called "Reset" in older versions of Firefox) can solve a lot of problems in restaurant Firefox as his default factory while saving your bookmarks, history, passwords, cookies, and other essential information.

The master password dialog box is not well labeled. No luck, it could be spoofed using JS and someone could then access all passwords?

IMO, request master password dialog box is not well labeled, and its identity (and authentic) seem a little in doubt whenever it appears. It is possible that someone could be spoof using JS and I could unwittingly put my "skeleton key" to a thief? Please tell me I'll be paranoid!

I don't think a script in an ordinary web page has the permission to read your passwords for other Web sites, even if you are not using a master password. It should be limited to see what password manager fills in the page.

For this reason, even if a page has captured your master password, I don't think that he could use it in a harmful way. But I'm maybe not quite devious.
