char ASCII value

I don't know how to get a HEXADECIMAL character value, but I want to know how to get the character of its HEX value. that is to say: I am 41 and I want to convert that "a." Is there a way to do this?

Thanks for your help.

How to find out the ASCII values for the Spanish character
Hello

I had an obligation to maintain the Spanish character and must also always records based on the Spanish character.

Kindly guide me for below.

To filter the records that contains Spanish characters?
To get the ASCII values for the particular column?

For example, we can find the ASCII value of 'a' using the select syntax ASCII('a') double.

But I want to find the value of the particular column ASCII values. That is to say. name.
For example, the customer name is 'Suresh', I want the ASCII values for the entire name of 'Suresh '.

Please do the necessary help / advice on that.

Thank you
Orahar
To expand on what I said in my first post, you want to do something in this direction:
```
with t (thename) as
  (
  select 'Suresh' from dual
  )
select thename
     , substr(TheName, level, 1)
     , ascii(substr(thename, level))
  from t
connect by level <= length(thename);
```
The result of the above query is:
```
THENAM S ASCII(SUBSTR(THENAME,LEVEL))
------ - ----------------------------
Suresh S                           83
Suresh u                          117
Suresh r                          114
Suresh e                          101
Suresh s                          115
Suresh h                          104

6 rows selected.
```
Note that the WITH statement is only there to simulate a table for this example. With a table, all you do is get rid of the with and replace it with the name of "t" for your table name (also the name of the column with name column has in your table).

Finally, I suggest that you post your question with, an example of table and the output you want for PL/SQL forum. There are people out there who will give you all sorts of ways to solve this problem.

How to find the ASCII value of the TAB?
Hi friends,

I'm trying to find the ASCII value of the TAB character using ASCII standard as:

SELECT ASCII ('< TAB >') FROM DUAL;

I'm running the command above in SQL * more.

Is not treated as TAB.
It is considered space and give the ASCII value of the space - 32.

Please let me know how?

Version of Database - 9i

Concerning
Anthony Alix.
Its only editor that gives you the problem; Try it on TOAD or sql developer, it works perfectly.

Is there a particular reason you want in sql * more?

Looking for an Ascii value within the chain
Dear all,

I want to find when the 92 ASCII value Hexagon is less significant for some reason, when people copy and paste a string, pointed in our database from MS Word, they are coming up as?. How would I find them. Here is an example of my table.

Table_Notes
Customer_id Notes
11111111 Hello, my name is Jonny B
Hello 11111112, I can? t find my hat <-see how the apostrophe is a? not a '
11111113 what is your name? <-who make the issue is supposed to be there

Any ideas?

The only thing I can think of is this:
Select
-case when notes like ' %? %' then 'Fail' else 'Pass' end
Of
table_notes;

However that show me everything, any ideas?
As s_2 pointed out, it is likely has something to do with your character in the database. The strange character is likely to be a result of the 'smart' quotes in MS Word is pasted into the field. If you're sure it's 92 hex (146 dec), then you might do something like:
```
SELECT CASE WHEN INSTR(notes, CHR(146)) > 0 THEN 'Fail' ELSE 'Pass' END
FROM table_notes;
```
Your posted case returns only lines with an exclamation mark actual. Tools like sqlplus display an exclamation mark when they can not disply the real character, but it is stored as the character of real.

Read byte with a value up to 127 lire byte with an ASCII value greater than 7F (127 dec)

Hello

I have to read a byte with a value greater than 127, Labview turn 27.

In help I saw that Labview provides a description of ASCII that pour values ranging up to ' 127.

What do I need to do?

LabVIEW 6.1

Windows XP

Hello

I want to read a byte with a maximum value of 127, but Labiew reurn arround 27 value

How do I do?

Rigid wrote:

Thanks for your help. I'm not changing lyke I understand (my English is poor quiet...)

I have another program that communicate with the instrument. I know byte (6) must be greater than 18 (greater than 7F actually).

But with Labview, I'm only 18.

While it might be higher than 18 x, an I8 is signed, and therefore it cannot be greater than x7F - it has a range of-128 to 127. A U8 is not signed, and it's why he has a range from 0 to xFF. However, x 18 is the same if you treat as signed or not signed. I don't see how LabVIEW can read a wrong value on the serial port. Are you sure you're looking at the correct byte? Your code shows that you split the chain twice. Are you sure that you do this properly?

Given that you use on Windows you can recheck the chain received using PortMon. Allows you to see what is actually received by the driver for the serial port on Windows.

P.S. I actually meant the whole byte function.

How to convert binary data from the Panel controls in ASCII values?

Hello

I seemed to face a roadblock with how to convert binary values in ascii.

I created this .vi to save all control values in an .ini file and call them at that time where I will carry out the .vi as shown in the file attached. Registration key to simply save the data and Cancel button discards all current changes.

I would like to understand how to retrieve all the values of control to ASCII, so I assign to a global variable for later use. I've looked everywhere for a good reference document, and I couldn't find one that would explain my question. I would be greatly appreciated if someone could point me in the right direction.

Thank you

I tried a simple way to save control values in the front panel

Not reinventing the wheel, when there are ready to use of solutions, for example:

http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/209753

Use the MGI save & restore settings VI of the palette (for example, it records all the settings that have been changed in a graph, which is very useful) and the MGI Save (restoration) Front Panel data live (to save and restore control values in the front panel).

Help with a sql using the ASCII value

Hello

I have a table with the following data

DOC_NO     CLIENT_REV
------     ----------
240          A
240          B
240          B
240          C
240          C
240          C
240          0
240          1
240          1
240          1
240          2
240          2
240          2
241          A
241          A
241          B
241          C
241          C
241          D

The requirement is retur the following values:

240          2
241          D

I tried with the ASCII function, but the necessary result is somewhat complicated. That is to say for a group of doc_no I need as many client_rev if there are numbers, if not then I need the largest letter.

How can I achieve this requirement?

Kind regards.

Hello

What do you mean by "the decision must be the minor doc_date?
It would be useful that you posted your desired results.
I assume you mean you want only the line with the doc_date lowest (for each doc_no).
in other words, the desired results are:

    DOC_NO L DOC_DESC           DOC_DATE
---------- - ------------------ ---------
       240 2 Description of 240 01-JAN-09
       241 D Description of 241 01-FEB-09

Here's a way to get these results:

  SELECT x.doc_no, x.last_client_rev, y.doc_desc, y.doc_date
  FROM     (     -- Begin sub-query based on table_a
     SELECT   doc_no,
                 MAX (client_rev) KEEP
                   (DENSE_RANK LAST ORDER BY TRANSLATE(client_rev
                                                       ,'ABCD012' -- Desired sort order
                                                       ,'012ABCD'  -- Actual sort order
                                                      )) AS last_client_rev
     FROM       table_a
        GROUP BY  doc_no
     ) x,
     (     -- Begin sub-query based on table_b
     SELECT       doc_no,
            MAX (doc_desc) KEEP (DENSE_RANK FIRST ORDER BY doc_date)
                         AS doc_desc,
            MIN (doc_date)     AS doc_date
     FROM       table_b
     GROUP BY  doc_no
     ) y
  WHERE x.doc_no = y.doc_no;

As you restrict the table_a lines are used, so now you restrict table_b lines are used.

First, let's review what you do with table_a.
Table_a has multiple lines with the same doc_no.
You only want to consider one of these lines: one that comes last, when to sort your particular way.
If your main query does not use the table_a:
It uses a subquery table_a-based which is a GROUP BY doc_no, to ensure that only the row by doc_no is used.

Now, what is the problem with table_b?
Table_b has as many rows with the same doc_no.
You only want to consider one of these lines: the one with the lowest doc_date.
So your main query should not use table_b:
She must use a subquery table_b-based which is a GROUP BY doc_no, to ensure that only the row by doc_no is used.

Character with the ascii value '0' does not not in NVL...

Hello
I have a question, work with "Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi" as our Source and target. For a record in the nvl (COLUMN, 'AA') target is back 'AA' but the same matching record in the source: nvl (COLUMN, 'AA') returns nothing (a data field where nothing is there), why what is happening? Every point of view...

Basically you have a CHR (0) in the column. And CHR (0) is not a NULL value. So its obvious NVL will not return AA.

It could be interesting to ask Tom "Strange Chr (0) '

How to check an ascii value of the character in the string
Hi all
I have a string that contain alphanumeric values.
I want only numeric values in this string.
FRO this purpose.
I created a varry
```
TYPE tab IS VARRAY(10) OF VARCHAR2(10) ;
   var tab
```
;
variable var of type varray contain this string

and now I want to check each character in this string at end of validation

How can I check this particular string

can I use loop?
Hello

If str is a string, then
```
REGEXP_LIKE ( str
            , '^[[:digit:]]+$'
            )
```
Returns TRUE if and only if str contains digits (0 ith 9) and nothing else.
Here's a way you can use REGEXP_LIKE in PL/SQL:
```
SET     SERVEROUTPUT     ON

DECLARE
    str          VARCHAR2 (10)     := '123.4';
BEGIN
    IF  REGEXP_LIKE ( str
                  , '^[[:digit:]]+$'
              )
    THEN
     dbms_output.put_line (  str
                    || ' is all digits.'
                    );
    ELSE
     dbms_output.put_line (  str
                    || ' contains something besides digits, or is NULL'
                    );
    END IF;
END;

increment ascii 9 to 10

First off apologies for posting this again. I tried everything and can not my post with the solution and I know that I had asked before. I use this to increment a field 'version '. When it comes to 9, the next char ascii is a colon, then the value goes from 9 to:. I need it to increment 10 and on-site. TIA! Sorry again!

SELECT 
CASE WHEN REGEXP_SUBSTR(UPPER(VERNUMBER), '[0-9]$') IS NULL
THEN TO_CHAR('1')
    ELSE
 
    REGEXP_REPLACE(VERNUMBER, '[0-9]$', CHR(ASCII(REGEXP_SUBSTR(UPPER(VERNUMBER), '[0-9]$')) + 1))
 
END NEW_VERSION
FROM DOC_INFO
WHERE DOC_INFO_ID = :P3_DOC_INFO_ID

Hi userRRRYB,

This gives a test:

SELECT CASE
          WHEN REGEXP_SUBSTR(UPPER(vernumber), '[0-9]+$') IS NULL THEN '1'
          ELSE REGEXP_REPLACE(vernumber, '[0-9]+$', REGEXP_SUBSTR(UPPER(vernumber), '[0-9]+$') + 1)
       END NEW_VERSION
FROM   DOC_INFO
WHERE  DOC_INFO_ID = :P3_DOC_INFO_ID

It will be useful,
John

sum of the ascii control sum

Hi, I need to create a checksum with my AScii commands, the checksum is the unsigned sum of the ASCII values reduced to the lower 8 bits. These 8 bits are then sent to a hexadecimal number in ASCII. I think it means I convert all characters in my ASCII 8 bit command and add them up. I then use a 255 and the remaining 8 bits are converted to hex and added to my order as ASCII characters. 1 / this sounds not correct and 2 / are there examples of this. I checked a little out but do not know if they are correct for me.

Something like that? The format of % 02 x format string formats a number to a hexadecimal number with 0 s leader, minimum length of 2 characters. Because you specified the lower case, I had to add the function of tiny.
