• Model maching class of regular Expression to validate the alphanumeric string

  Hello
  MY version of DB is Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Production 64-bit
  
  I wanted to use the model maching given by oracle classes to check whether a given input string is alphanumeric.

  Hi knani
  I need to check whether the input string is alphanumeric.

  That's why "ABC" all entries as '1234', '123ABc', must return true.

  Also can the alphanumeric string contains characters that are available on the keyboard which can be seized of it.

  Concerning
  Arun

  I just read your requirement "all printable characters.

  Try:

  select regexp_like('string','^[[:print:]]$') from dual
  

  to get only the records that have only printable characters.

• How to dynamically change the names of columns LOV

  Hello

  I use JDeveloper 11.1.1.4

  I have only one requirement, while I need to change the names of columns in the list of values dynamically.

  How can I achieve it.

  Please help me.

  Kind regards

  John.

  Hello

  > But I want to change the column names 'ID' and 'Name' dynamically.

  Based on what? Condition? If Yes, have you tried to set the text for the label as an expression? If not based on the condition, you can also expose the VO to Java Impl and need a way to get the attribute and change its label.

• Y at - it an option to print the names of columns?

  Hi developers out there!
  
  Problem:
  When I try to print the data in the table, the names of columns like "COL01', 'COL02' and so on.
  But initially, they have other names.
  Am I missing something?
  
  Best regards
  Ruslan.

  If you go to your report and click on the 'Report Attributes' tab. You will see all the names of your column headers. and a group of radio buttons at the top of the page. Select custom, and then change the names of your column headers.

  In addition, it seems that on your 'Definition of the region' tab in the Source box, you checked the option button "use generic column names (analysis of query runtime only). Try to select the other radio button "use query column names-specific query and validate.

  Good luck.

• ORE: the names of columns not valid cost.matrix

  I'm trying to use the method odmDT with application costs customized as follows:

  > dt.mod = ore.odmDT (default ~.,credit_train,max.depth=20,cost.matrix=matrix(c(0,1,4,0),nrow=2)

  but I get the error:

  Error in ore.odmDT (default ~., credit_train, max.depth = 20, cost.matrix = error_cost):

  ORE: the names of columns not valid cost.matrix

  I can't find any documentation anywhere on how exactly this cost matrix must be specified.

  Any help would be appreciated

  The value for cost.matrix currently requires a data structure object. The following examples using the NARROW data successfully pass a frame of data for the value of cost.matrix:

  R > NARROW.costs.gender<- data.frame(actual_target_value="">

  PREDICTED_TARGET_VALUE = c("M","M","F","F"),

  COST = c (0.25, 0.75, 0.0, 0.0))

  R > NARROW.costs.class<- data.frame(actual_target_value="">

  PREDICTED_TARGET_VALUE = c (0,0,1,1),

  COST = c (0.25, 0.75, 0.0, 0.0))

  R > dt.mod1<- ore.odmdt(gender="" ~="" .,="" narrow,="" cost.matrix="">

  Summary (DT. MOD1)

  R > dt.mod2<- ore.odmdt(class="" ~="" .,="" narrow,="" cost.matrix="">

  Summary (DT. MOD2)

  I filed a bug so this behavior can be evaluated for a future release of Oracle Enterprise R.

• return the names of columns which line values are not null.

  Hi I m a new db admin guy, and I need a sql script that should return the names of columns of the given table. and the returned column must be the value (fyi - if the column contains the value null column name would not come to the o/p of sql).
  Exmple:
  name of the table - A
  fresh status s.no name brand
  1 null aa 45P
  paid 2 null bb 30
  3 cc paid 35P
  
  (FYI - 1) if I give the table name (A) and s. n. (2) o/p should be - name, mark.
  (2) if I give the status of tablename (A) and s. n (1) the o/p should be - name, brand.
  
  Thank you

  BTW,
  The previous solution is for all values of the column, if you want a specific line, you can add it in where clause.
  I mean in your example, it you look like:

  SET serveroutput on;
  
  DECLARE
     l_cnt          NUMBER;
     l_str          VARCHAR2 (255) := '';
     l_table_name   VARCHAR2 (255) := 'YOUR_TABLE_NAME';
     l_col_cond     VARCHAR2 (255) := 'S_NO';
     l_val          NUMBER         := 1;
  
     CURSOR c_col
     IS
        SELECT column_name
          FROM user_tab_columns
         WHERE table_name = l_table_name;
  BEGIN
     FOR i IN c_col
     LOOP
        EXECUTE IMMEDIATE    'SELECT COUNT ('
                          || i.column_name
                          || ') FROM '
                          || l_table_name
                          || ' WHERE '
                          || l_col_cond
                          || ' = '
                          || l_val
                     INTO l_cnt;
  
        l_str := l_str || CASE
                    WHEN l_cnt = 0
                       THEN ''
                    ELSE i.column_name
                 END || ',';
     END LOOP;
  
     l_str := SUBSTR (l_str, 1, LENGTH (l_str) - 1);
     DBMS_OUTPUT.put_line (l_str);

• change the names of columns in the automatic process line fetch, edit the code

  Hello
  
  I created the master detailed form of two tables, and then I changed one of the names of columns in the table which is the detail.
  
  of course the extraction process could not recognize the name of this column (as it is no longer exist), so I need to change the column name in the query of in the current name.
  
  Ditto for line process transformation, to insert a new line.
  
  I guess it's easy, but I don't know where to find the ASR process query request,
  suggestions please!
  
  Kind regards.

• A list of the names of columns in addition to the OMB

  I have to add several operators to approximately 120 maps and trying to learn more about OMB in the hope that it might be able to save time (and my Visual/mental health ;-) acuity. However, each map works on different tables, each with its own unique set of columns. This list of columns must be added to a GROUP OF property of an aggregator.
  
  Is there a way to get a list of the names of table columns in the OMB, so I can get this GROUP BY list? So far, I couldn't find one.
  
  I use 10.2.0.1
  
  Thank you
