• How does whitespace or null values or characters set effect set in the query?

  Hi all

  I have a question about client side Oracle database tools. I have Oracle 11g installed on the server and I use PL/SQL developer tool to retrieve information from the server and then I copy paste this query in PL SQL Developer my company built in box of function of the application that executes the same query as client tools and the results.

  When I write the request by spaces of the Tools client-side IE the PL/SQL developer tool and copy paste at my request of builtin company gives slow down me execution, but if I remove the white of the query space by copying the application of PL/SQL developer(client side tool) to Notepad first and then copy back at my request and gives me a faster execution.

  For example:

  Original Request: with whitespace

  Select

  *

  Of

  Double

  Ask without spaces faster tracks:

  Select * twice;

  I want to the reason behind this slow execution and also if you could explain in detail would be great that I am no expert oracle.

  Also, I wanted to know that character set parameters from the client side tools slow running query? As I copy the request of PL/SQL developer tool

  Thank you

  HP, I have has been suggest you determine if the difference in performance is due to how the application prepares and processes SQL or if the difference is in Oracle.  If you can duplicate the issue in Oracle using SQLPLus then you can use the Oracle tools such as autotrace, SQL, trace etc... to determine how Oracle handles each request.  On the other hand if the time of execution in SQLPLus is the same then you know that the problem lies in the application.  Depending on whether you have access to the source you can or will not be able to track down the issue and resolve it.  Otherwise always paste the capture into the plan text and edit it to remove the unnecessary lines before copying them the text into your application tool.

• new to 4.02, no grid or column names in the query results

  It is a bit strange, I have SQL Developer 4.02 just installed, and I don't see grid or column names in the query results.  Don't see anything useful in tools > Preferences, what don't get me?

  The worksheet gives you a couple of different ways to run a query...

  1. instruction execute sheet icon toolbar (large green arrow, or Ctrl + Enter).

  This produces a results tab of the query with the data displayed in a grid.

  2. worksheet icon toolbar Execute the Script (the small tip of the green arrow on lined paper, or F5).

  This produces a tab out of the Script with the data displayed on the printer.

  If execution of the statement to Execute the Script, using some SQL * most orders will remove the column headers:

  1. set the position

  2. set the pagesize 0 (or 1 or 2).

  Pagesize and linesize default is - 1.  By default, the spreadsheet is free for formatting output script as he wishes.  If you have not changed these settings in the spreadsheet, then see if you point to a startup script in Tools > Preferences > Database > name of the connection startup script file

  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.

• 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;

• ALTER Table of the default Oracle and the length of name of column Type

  Hi all
  
  I want to increase the length of the table names and the names of the columns in Oracle.
  
  By default, it is set like this:
  
  SQL > dba_tab_columns desc;
  
  TABLE_NAME NOT NULL VARCHAR2 (30)
  COLUMN_NAME NOT NULL VARCHAR2 (30)
  ...
  
  Is it possible to change the VARCHAR2 (30) to VARCHAR2 (100)?
  
  Published by: sukrandere on 12:21 10.Mar.2010

  Table names and column are all two identifiers
  According to the documentation, the maximum length of an identifier is 30 characters.
  It is hard coded in the database software and you can't change it.
  Or do you need to change.

• 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

  Set tab_cols [OMBRETRIEVE 'EMP' GET COLUMNS]

  or such a thing on a map...
  define the atts [OMBRETRIEVE '$mapName' OPERATOR '$lastOperator' GROUP 'OUTGRP1' GETTING ATTRIBUTES of MAP]
  foreach att $atts {}
  the value of EO [OMBRETRIEVE MAPPING '$mapName' OPERATOR '$lastOperator' GROUP 'OUTGRP1' ATTRIBUTE '$att' GET PROPERTY (EXPRESSION)]

  Could be interesting furtively to the SQL to map the Accelerator for the OMB snippets too.

• 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.
