• analyze the table & dbms_stats (chained lines)

  Hi guys,.
  
  Understand that dbms_stats collect statistics on (chained rows).
  To get chained lines, we can use one of the below:
  1. analyze the < table_name > table list chained rows;
  2 analyze the table < table_name > statistical calculation;
  
  the first lists the information chained rows in the CHAINED_ROWS table.
  the 2nd is best so that the information of chain_cnt are fulfilled in dba_tables. I can easily get the percentage of channel count by diviiding with the num_rows (for example if you need to list tables with 10 > string cnt percentage it would be easy).
  
  Right now, I'm leaving the need to collect statistics for night work by default oracle (who gather for table with variation in percentage of stale or > 10)... However, come together to string cnts.
  Can advise how can I get the string cnt without risking my existing services?
  
  And also will analyze statistics of table < table_name > estimate; replace my existing histograms?
  
  Thank you

• Analyze the table after loading

  Hi gurus
  
  Let me know how we analyze the target table after loading to finish using an interface.
  
  Concerning

  Hi Mary,

  There are two ways to do it,

  1. customize your IKM own target of Analyze table step added.

  2. create a procedure of ODI which will analyze the target table and can be called after the success of the loading data.

• Analyze the table with a DEGREE = &gt; AUTO LEVEL

  I'm using the version of oracle 10g.

  In my view, a valid value for the parameter DEGREE there in aid of the oracle. (http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_stats.htm)
  
  Degree: Degree of parallelism. The default for the level is set to NULL. The default value can be changed using the SET_PARAM procedure. NULL means use the default value of the table specified by the LEVEL clause in the CREATE TABLE or ALTER TABLE statement. Use the constant DBMS_STATS. DEFAULT_DEGREE to specify the default value based on the initialization parameters. The AUTO_DEGREE value determines the degree of parallelism automatically. It's 1 (series performance) or DEFAULT_DEGREE (the default value of the system will depend on the number of processors and initialization parameters) according to the size of the object

• adding new data in the table property variant

  Hello guy,

  I have a Qml property

  property variant placeName:[]
  

  I would now like to add data in this property at run time.

  I checked this link:

  http://Qt-project.org/doc/Qt-4.8/QML-Variant.html

  but there, I found that we can "Update" the property data.

  What to add new data?

  Please help me as soon as possible...

  property real estate to qml aren't real javascript arrays, so to mutate them you need a reallocation.

• How can I search and return several items from the table quickly (like Matlab find)?

  Hi, I'm a pretty experienced Labview programmer, and I've always wondered if there is a way to quickly search for pictures on several items that meet the selection criteria, equivalent to the Matlab find command.  While my inability to do in Labview has always annoyed me, I now have an application that requires this capability and I need to find a solution.

  Is the fastest way I've found to do this in labview to perform comparisons on the data vectors, then use the Boolean value that results from vector to analyze the table using a loop and shift registers.  I enclose an extract vi a analysis comparative vi to one of the simple searches that I need to do.  On my laptop, this research takes about 600 ms.  In comparison, the equivalent in Matlab:

  newArray=oldArray(find(oldArray(:,4)./oldArray(:,2)>1.5),;

  runs in about 1.2ms.  So, the way I am doing this in Labview is only 400 times slower

  Needless to say, I need to make these types of research many times, and these additional 599 ms start to add up pretty quickly!

  Thanks for your help,

  Aaron

  Hi Aaron,

  the slow part is probably "build group" of the node in the loop.

  Try this:

  Define an array the same size as the input data (or simply uses a copy of it) and the wire that to the shift register. Keep a counter of lines found in the loop. Use IndexArray and ReplaceArraySubset for the loop to move rows found at the beginning of the table (overwrite the 'bad' lines). After the loop simply ReshapeArray the number of found lines...

• the table scan

  Hello
  
  I would like to know what is meant by the analysis of the table and how to analyze the tables?
  
  can you please provide me steps docs about that.
  Thank you
  Vijay

  The "ANALYZE" command is obsolete and to be used only for specific purposes (for example, the keyword VALIDATE or to count the number of chained rows).

  The DBMS_STATS package with its set of procedures replaces that command. These procedures, as well as the automated job/tasks already configured in 10 g and 11 g, should be used to collect optimizer statistics. Essentially of statistics on the nature of the data that is present. The SQL optimizer then uses these statistics to determine an execution plan to retrieve the data requested by the user/application.

  Parsed table.

  Do not use this command to analyze the tables so you need to use DBMS_STATS. Procedure GATHER_TABLE_STATS then check again.

• Rename the table require re-run the stats?

  OS: OEL (last) 64-bit
  DB: 11 GR 1 material
  
  I need to create a copy of a large table A in production (call of the new table B). The data are the same, but the physical layout of the tables is different (different partitioning scheme is used between table A and B).
  When I go to move table B to replace table A (which will be eventually abandoned), should I raise his stats on table B?
  
  It's
  (1) table to become A_OLD
  (2) table B becomes table A
  
  I have to raise its stats on table A in step (2)? Is there something else that needs to be done?
  (I do this to limit the impact to the GUI that uses this table - the name of the final table does not change so the GUI should not be affected).
  
  See you soon!

  Yes, I have to raise his stats on the 'new' A table even if it has the same data and the name (after renaming) but different partitioning scheme (physical model)? It seems to me that the answer would be 'yes '.
  Otherwise, not the optimizer does not fail to recognize the new partitioning?

  (1) Board toys (all data) and table Toys_New (empty)
  (2) the Toys_New table is loaded with toys data table (the two tables have the same data - only difference is partitioning)
  (2) the toys table is renamed table Toys_Old (this will be served at a later date)
  (4) table Toys_New is renamed table Toys

  And I was thinking - I forgot to talk about first-hand - Toys_New will have the same indexes, but of course the clues will have unique names from toys (to avoid the error "object already exists".

  Given that the last note, I am convinced more than stats must be run on Toys_New after step (4)

  See you soon!

  Yes, you must.

  Name of your new table is 'Toys', but this new table is totally different than the old toys. If you need to analyze the table again.

• graphic positioning anchored outside the table

  I have a table of single cell with a small graphic which is anchored so that it is positioned to the left of the table and the Libya in the field of the margin. The reason why the chart cannot be in a table cell is because he has to the protrusion in the margin beyond the text frame.

  The table is inserted periodically throughout several documents. The lines of text in the table can vary - sometimes it will be 1, 2, 3 lines of text in the cell.

  I need to have the rooted graph centered vertically to the left of the text in the cell - the distance of 'y' for the embedded chart varies according to the number of rows in the table cell. Is there a way to automatically center the graph so that it does not need to be positioned manually for each table?

  Jay, the definition of the paragraph that the table is to right-alignment has nothing to the text in the cells. Try it: make the table larger than your image, then select the entire table, including the paragraph back, using the text tool, then set it to center alignment (it'll stick both sides), then to the right (it'll stick to the left, 'out' in the margin).

  (If I remember correctly, that is.)

• Collect statistics on the table with indexes of text only?

  I gathered statistics for a table that contains a text index
  EXEC DBMS_STATS. GATHER_TABLE_STATS (USER, 'CONADDR', estimate_percent = > 10, block_sample = > TRUE, cascade = > TRUE);
  
  There are a lot of tables/indexes not monitored (e.g. DR$ TI_CONADDR$ I). Do I have to analyse the tables there, too? The Guide Tuning Oracle text mentions just to analyze the table of "base".
  
  Oracle DB version is 10.2.0.4.
  

  select table_name, last_analyzed, num_rows from dba_tables where table_name like '%CONADDR%';
  CONADDR     11.08.2010 10:29:37     17944660
  DR$TI_CONADDR$I          
  DR$TI_CONADDR$R          
  DR$TI_CONADDR$K          
  DR$TI_CONADDR$N          
  
  select index_name, table_name, last_analyzed, num_rows from dba_indexes where table_name like '%CONADDR%';

  DR$ table do NOT need to be analysed - and should not be.

  As "secondary objects", they will not be analyzed by orders based on patterns, and it is strongly recommended to not analyze manually. All commands that access these tables are set correctly without the input of the optimizer.

  CJ,
  dbms_utility.analyze_schema has been deprecated since 9i - you should use dbms_stats.

  Therese, by default there is a stats work gather running on your database, pick up "bland" statistics, do you have it disabled?
  If you want or need to run manually, dbms_stats.gather_database_stats is what you need. Documentation is here http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/stats.htm#i41448

• analyze the differences between the 2 tables

  Hi all
  I have two tables, more or less the same. Suppose that the tables are the same for now (same columns, data types).
  One contains lines that are not in the second, the second contains documents that are not in the first table.
  How can I write a select statement would separate the lines 2 and not 1, lines 1 and not 2 and the municipality.
  I've already solved it by a bit of PL/SQL code, however, I'm looking for something elegant...
