Char to upper case

Hello:
The question is simple..
How do you people convert a char to upper case?
Regards
pete

this way is good enough as for me:
               char c = chars;
               String s = String.valueOf(c);
               result.append("[" + s.toUpperCase() + s.toLowerCase() + "]");

Changing field value to upper case

I am using EditCurrentRecord. How do I convert the value that the user enters to uppercase?
There is a setOnChange() method in HTMLInputElement. But how do I get HTMLInputElement from HTMLFieldRenderer in EditCurrentRecord?
Thanks in advance.
Stephen

One central way to solve this problem is to add a method in the Entity Object attribute setter like this:
public void setYourAttributeName( String value ) {
// If non-null, uppercase the value before setting it.
if (value != null) value = value.toUpperCase();
setAttributeInternal(....);
}Then, regardless of client, the value will be forced to uppercase.

Update column data to Upper Case in parent and child table

Hi ,
I am facing issue while updating column value to upper case in parent table and child table. How can i do that ?
when updating parent row:
ORA-02292: integrity constraint (XXXXXXXXXXXXXX_FK) violated - child record found
When updatng corresponding child row:
ORA-02291: integrity constraint (XXXXXXXXXXXXXXXX_FK) violated - parent key not found
how can i update on both the places ?

Why do you need to do that?
That is just ONE of several questions you should answer before you start modifying your data.
1. What is your 4 digit Oracle version? (result of SELECT * FROM V$VERSION)
2. If both values are the same case what difference does it make what that case is?hen you don't need to alter your original data.
3. What is the source of the column values you are using now? If you change your data to upper case it will no longer be identical to the source data.
4. What is your plan for enforcing future values to be stored in UPPER case? Are you going to use a trigger? Have you written and tested such a trigger to see if it will even work the way you expect?
5. Why aren't you using a surrogate key instead of a 'business' data item? You have just demonstrated one reason why surrogate keys can be useful: their actual value is NOT important.
You should reexamine your problem and architecture and consider other alternatives.
One alternative is to add a new 'surrogate key' column to use as the primary key. Just create a new sequence and use a trigger to populate the new column. Your current plans will require a trigger to perform the case conversion so instead of the just use the trigger to provide the value.
If the change is being done to facilitate searching you could just add a VIRTUAL column UPPER_MY_COLUMN and index that instead. Then you could search on that new virtual column and the data values would still be identical to the original data source.

Converting char to upper

How can I convert a char to upper case like you would a string?
char code;
String Stringcode;
code = letter.getText().charAt(0);
Stringcode = String.valueOf(code).toUpperCase();
Can't I just convert the char to upper?

public class Test {
    public static void main (String[] parameters) {
        for (char ch = 'a'; ch <= 'z'; ch ++) {
            System.out.print (Character.toUpperCase (ch));
}

Convert mixed case value in colum into upper case values

Hi All,
I have got a table call emp and has the following colums:
id number 10
suename_name varchar2(20)
given_name varchar2(20)
position varchar2(30)
date_hired date
Now the values in colums are mixed case and I need to change them to upper case. I think I need to use upper function to do it.
Could anyone help me by providing me sql/pl sql script to through each colum in emp table and change them to the upper case.
Many Thanks
Michael

Hi,
If you really want to try this using PL/SQL, then you'll have to use dynamic SQL, something like this untested code, since the table and column names are vaiable:
SET   SERVEROUTPUT ON SIZE 50000
DECLARE
     sql_txt     VARCHAR2 (4000);
BEGIN
     FOR r IN ( SELECT table_name
               ,       column_name
               FROM    user_tab_columns
               WHERE   data_type = 'VARCHAR2'
          --   AND     ... -- if you don't want all columns in all tables
     LOOP
          sql_txt := 'UPDATE "'
               || r.table_name
               || '" SET "'
               || r.column_name
               || '" = UPPER ("'
               || r.column_name
               || '")';
          dbms_output.put_line (sql_txt || ' = sql_txt');     -- For debugging
          -- EXECUTE IMMEDIATE sql_txt;               -- For real
     END LOOP;
END;Dynamic SQL (here) means creating a string that contains the SQL statement to be done, then using EXECUTE IMMEDIATE to run it.
Whenever you write dynamic SQL, it's a good idea to only display the SQL statement during the early stages of debugging. When it's displaying correctly, then you can try un-commenting the EXECUTE IMMEDIATE line.

A little more complicated, but a lot more efficient:
SET   SERVEROUTPUT ON SIZE 50000
DECLARE
     sql_txt          VARCHAR2 (4000);
BEGIN
     FOR r IN ( SELECT    table_name
               ,         column_name
               ,         ROW_NUMBER () OVER ( PARTITION BY table_name
                                  ORDER BY       column_name
                                )     AS column_num
               ,            COUNT (1)     OVER ( PARTITION BY table_name
                                )     AS total_column_cnt
               FROM      user_tab_columns
               WHERE     data_type = 'VARCHAR2'
          --   AND       ... -- if you don't want all columns in all tables
               ORDER BY table_name
               ,            column_name
     LOOP
          IF r.column_num = 1
          THEN
               sql_txt := 'UPDATE "'
               || r.table_name
               || '" SET "';
          ELSE
               sql_txt := sql_txt || ', "';
          END IF;
          sql_txt := sql_txt ||
               || r.column_name
               || '" = UPPER ("'
               || r.column_name
               || '")';
          IF r.column_num = r.total_column_cnt
          THEN     -- This is the last row for this table; run it
               dbms_output.put_line (sql_txt || ' = sql_txt');     -- For debugging
               -- EXECUTE IMMEDIATE sql_txt;               -- For real
          END IF;
     END LOOP;
END;
{code}
The difference is that the first solution produces and executes a separate UPDATE statement for each column, like this:
{code}
UPDATE "TABLE_1" SET "COLUMN_A" = UPPER ("COLUMN_A");
UPDATE "TABLE_1" SET "COLUMN_B" = UPPER ("COLUMN_B");
UPDATE "TABLE_1" SET "COLUMN_C" = UPPER ("COLUMN_C");
{code}
but it's much more efficient to do change all the columns at once, as long as you have the row in hand. So the second solution only creates one SQL statement per table, like this:
{code}
UPDATE "TABLE_1" SET "COLUMN_A" = UPPER ("COLUMN_A")
           ,   "COLUMN_B" = UPPER ("COLUMN_B")
           ,   "COLUMN_C" = UPPER ("COLUMN_C");
{code} where every line above corresponds to a row fom the query. The first line for every table will start with
{code}
UPDATE "TABLE_1" SET "but all the others will start with
{code}
and only on the last column for a given table will the statement be executed.

Changing to Upper case?

Is easy way to change the input character
from keybord to upper case directly, i mean
at the same time when the user press a key,
the upper case show up on textField? Or i have to do that manually when cursor/mouse
left the textField?

cut&paste from the swing doc javax.swing.jtextfield:
public class UpperCaseField extends JTextField {
public UpperCaseField(int cols) {
super(cols);
protected Document createDefaultModel() {
return new UpperCaseDocument();
static class UpperCaseDocument extends PlainDocument {
public void insertString(int offs, String str, AttributeSet a)
throws BadLocationException {
if (str == null) {
return;
char[] upper = str.toCharArray();
for (int i = 0; i < upper.length; i) {
upper[i] = Character.toUpperCase(upper);
super.insertString(offs, new String(upper), a);

I was in a Pages Doc and inadvertently had the Caps Lock on. How Can I change all the text I typed from Upper Case to Lower Case?

I was in a Pages Doc and inadvertently had the Caps Lock on. How Can I change all the text I typed from Upper Case to Lower Case?

Several protocols may be used.
Here I describe two of them.
(1) the one which I use : install and use the "Convert to Lowercase" service available in the free WordService
(2) copy your text, paste in TextEdit and enter the Edit menu.
I guess that you will recognize the items in your English menu.
I apologize but I don't know the English items.

Can you use lower case in other files? If not, then go to the far right of the tool options and click the little four-lined square and choose Reset Tool.

https://dl.dropboxusercontent.com/u/103434771/meditowers/IMG_0245.MOV
here is how the normal setting should be
Alt + shift need to change to lower case English
then Alt shift one more time will go back to Hebrew
now if you hit on the caps lock you will be in English all the time with Upper Case

Tim,
In that case, use Peter's second suggestion, "Wordservice".

Capitalization doesn't work as described. One can start with lower case and change to upper, but changing from upper case to any of the other options doesn't work. Is there a way around this or is this just a glitch that needs fixing?

I think it does work as described, but the description is not very complete. Capitalization does not change any of the characters that you type; what it does is allow some of the lower case characters to display as capitals. If you copy the result and paste it as plain text, you'll see that the lower case characters are still there. It doesn't actually say anywhere that it can make capitals display as lower case, and it can't.
The obvious way around this is to actually type what you want.
The more powerful way is to install WordService from Devon Technologies which adds the functionality of Pages' capitalization menu as well a lot of other ones. WordService actually changes the character to the one displayed, and it works in most of the applications on your Mac.
