• Stats not registered in the stat table use with gather_table_stats

  During the collection of statistics with DBMS_STATS. GATHER_TABLE_STATS and passing stattab parameter partitioned table, his stats are not saved for this partition in the table user stat unless it is executed twice. Here's the statement that I'm running. If I add a new partition and try to collect statistics for it and store it in the user table stats, it is not be stored even if his dictionary stats are updated. If I run the second time, it will update the entries in the user table stat.
  
  Start
  DBMS_STATS.gather_table_stats ("OWNER",
  tabname = > 'table_name ',.
  partName = > "P20090824"
  estimate_percent = > 2,

  I used similar options and it worked all the time. Only difference is I used the granularity-online 'PARTITION Maybe you give him a try.
  Also try the stat of gathering and export to stat table separately.

• How to use FOLLOW-UP and COMPRESS the clause of the CREATE statement TABLE?

  my oracle's 10g and the statement of create table below:

  CREATE TABLE S005.q100

  (

  Q1 tank (1)

  )

  NOMONITORING;

  After you create this table, I ask USER_TABLES, but the value of the follow-up column is YES.

  I think there should be no how is? and also I have the same problem with the COMPRESS.

  Thank you very much

  
  

  Hello

  Heap - organized tables are your usual routine tables. It is created using the BUNCH of the ORGANIZATION of the CREATE TABLE statement clause. This is the default value.

  The other variant of this clause is ORGANIZATION INDEX, which means that you will create an organized Index of Table. In other words, it is a table that is stored in a B-tree, like an index.

  You also have an EXTERNAL BODY, which means that you will create an external table. Here is generally flat files outside of the database that you can order the database to see tabular to use SQL (read only) against. You will also need the settings on how the data are presented on the file, so that your database knows which column will match that of the data.

  The COMPRESS on 10G is known as the "basic compression" and it works on ordinary table segment blocks, which are organized by a bunch of tables.

• Hyperlink in the cell of a table in object state multi does not work

  Hello

  We have an app (DOS2015), which includes a gallery (with the status of multiple object) and on two of the pages State tables there.

  In certain cells in these tables are texts with hyperlinks. And all these hyperlinks do not work in dps 2015.

  (They do not work also in the folio Viewer. But they work if I copy the table into the object status multi on a normal page.

  It is by design or is it a trick?

• How do you return a blank in table 2, when there is no data in the cell related in table 1?

  I run a recreational League of golf and have been recording the scores of the players (50 + players in total) with the intention of maintaining a form of disability from the League.

  So far, I did most of the calculations manually in number. Recently, I have experimented using the Lookup function but have encountered a problem with the time where the player does not play this week.

  In table 1, where I do all scores record cel when they do not play is left blank. However, in table 2 than corresponding cel returns a 0... strikes completely out of whack handicaps.

  Here is what I used in table 2 for the information of table 1...  SEARCH (name, 2016 Stats::Table 1 $Last: $ name, 2016 Stats::Table 1::G44)

  I also tried to add an IF statement, but I have obviously not understood correctly as he said I tried to refer to a cel in the statement itself.

  Example of the disability Page in the table 2 list a 0 is returned in cel 6... which is then averaged in the cel of last second... namely the problem. The cel with the 6 in it is a formula that counts the number of moves played and see it 6 because it counts as a trick played 0. This shows the wrong average score of 65.666

  Them	A	78																						1	78
  Me	Me	80	75	81	0	81	77																	6	65.6666666666667	-10

  As it appears in table 1. indicating the total number of rounds played in 5 and returning the precise average score of 78.8

  Hi pondball,

  (Could be my 'golf name' somedays)

  

  Formula in Handicap::B2 and filled to the bottom and right at Handicap::X4

  = IF (LOOKUP ($A, data: $A, Data::B)=0,"",LOOKUP($A,Data::$A,Data::B))))

  IF compared the results of the first SEARCH and if it is zero, returns an empty string. If the comparison returns FALSE, the second SEARCH is called, find and returns the result of zero. AVERAGE does not take into account all results of text, including the string NULL, a zero-length text value.

  COUNT (used in the column count the number of turns) also ignores the text values.

  4th place of disability shows one of the reasons for not using LOOKUP.

  SEARCH alwas accepts a "close fit" with the search value. 'near match' for RESEARCH is defined as 'the largest value equal or less than the value of the research', and for the values text, "less than or equal" can be described as "identical or come forward in a list of items of text in alphabetical order.»

  For us, the other two values in the name list are 'less' us and the most important is 'Them', the values for 'Them' are returned.

  For this reason, I tend to use VLOOKUP instead of RESEARCH in many cases.

  VLOOKUP present the disadvantage of requiring her research-where location which will be the first column of the lookup table (which is not a problem here, because the location of the research is one ot the column data table).

  But also has the advantage of af being able to require an "exact match" search value.

  Here's the same tables of two, with VLOOKUP replacing LOOKUP. Note that the VLOOKUP function has a different syntax than the LOOKUP function.

  

  Formula VLOOKUP in Handicap::B2, filled with verse down and right at Handicap::X4:

  = IF (VLOOKUP ($A, Data: $A:$ X, COLUMN (), FALSE) = 0,"", VLOOKUP ($A, Data: $A:$ X, COLUMN (), FALSE) ")

  Written as above, the formula works correctly in rows 2 and 3, but will just return the error in the 4th row triangles, since it will not find a match (exact n) for 'Us' in column A of data.

  After confirming that it produces no unexpected error, wrap the formula in function SIERREUR as shown below and repeat the filling down and the right filling operations above.

  SIERREUR function interrupt all errors, including those affecting the results without your knowledge if they occur. Always delay adding IFERROR until you know what are the errors he fools.

  =IFERROR (IF (VLOOKUP ($A, data: $A:$ X, COLUMN (), FALSE) = 0,' ", VLOOKUP ($A, data: $A:$ X, COLUMN (), F ALSE))," ")

  Y2: = COUNT (C2:X 2)

  Z2: = AVERAGE(C2:X2) (base form)

  Z2: = IF (Y = 0,' ", AVERAGE (C2:X 2)) (real form)

  The encapsulation of the AVERAGE function in the IF statement deletes the calculation if the number of items to the average value is zero, AVERAGE preventing from return to a division by zero error. The number of circles in the column there is NOT used in the calculation of the average (AVERAGE did his own count), but is used as a switch 'OK to calculate' leaving the calculation of the AVERAGE to move forward.

  Kind regards

• Best Index on a column with low cardinality on a high DML activity table?

  I wanted to ask a question about the indices? I have a table which is the main table in the my system it holds nearly 65 000-1000000 rows on any average day. Each line has a (mandatory) batch, it can be 6 different status which is held in the state table. The distribution of status id in the master table is shown below. There is no index on this column, it has a low cardinality, but there are many dml moves in this table. However the State is the main request, the report runs against, so it made a full table scan every time. Users run their applications via an interactive report on Apex 4.0 and it runs slowly. It seemed to be a lock on the $ wwv_FLOW_PREFERENCES caused by this slow execution of interactive report query in this table for and is it locking associated with a slow interactive report query?

  SELECT * from Main_Table where batch =: b2 A full table scan is done in this case. Distribution of status id in the main table 0.12% Reopened pending 1.01% Current 0.17% Pending 0.01% Closed not resolved 96,44% Closed 2.24% Open

• locked table statistics

  Hi all
  We actually locked a stats table (table 1) with the intent to prevent the stats to gather nightly car to pick up the collection of statistics.
  Understand that the night together work kick start his stats at 22:00 every day (during wkday).

  The manual below for stats gathering will run about 4 hours.
  If start us at 8:30, the evening below meet his stats (22:00) pick it up for the collection of statistics?
  As the first sql will unlock the stats and lock only after the completion which is about 12 h 30.

  DBMS_STATS.unlock_table_stats exec ('AC', 'TABLE1');
  exec dbms_stats.gather_table_stats (ownname = > 'ac', tabname = > 'TABLE1', estimate_percent = > 50, cascade = > true, method_opt = > 'for all columns size 254');
  DBMS_STATS.lock_table_stats exec ('AC', table 1);

  Thank you

  Haven't seen your version mentioned, but there may be no need to unlock if you update the manually. Just add the setting force for your call at gather_table_stats if your version has this option.

  What is the first preference of the optimizer statistics?

  >
  Well Yes! There is only a single set of statistics for a table. Collect statistics for the table they are.

  Collect statistics for the scheme; It gathers statistics for all objects in the schema, including that the table and these new statistics replace no matter what his stats were there before. Who stops you having to talk about all of these objects by name.

  Collect statistics for the database; It gathers statistics for all objects in all schemas. Yet once, he never stops you have to talk about all schemas or objects by name, one at a time.

  and no matter that collect statistics for a table, both will be updated in one place or schema?

  Now, you have got it.

• DBMS_STATS: What removed his stats?

  Hi all
  
  This is probably a stupid question, but I've searched high and low and have not found an adequate answer to the following: when deleted stats?
  
  I read that his stats table and index deleted whenever truncate you a table, but the (minimal) tests, I did confirm this. "Essays", I mean that I tried to truncate a table and then export and view the statistics of table via DBMS_STATS. EXPORT_TABLE_STATS (and I said 'minimum')... The table statistics seem to have been ignored next truncation.
  
  Table / index stats deleted when you truncate / drop / delete all records from a table? Or they not removed at all?

  Hello

  statistics on the table are deleted when you call dbms_stats.delete_table_stats or when you drop the table. Why you would think that Oracle would secretly remove its stats table behind your back unless you ask him to? If you have read somewhere you should post a link to that statement - we cannot judge him without the context, but these days there are a lot of stupid things posted on the internet, this could be one of them.

  You should trust what you see (your own tests) on what you hear, especially from unknown people on the internet.

• Flashback work table with a deleted column

  Hello
  
  I have the following problem.
  
  I accidentally dropped a column containing the data of a table and to restore the state table, it was before I did.
  
  I found a reference on the internet which States that you can use flashback to retrieve a table to a set in the past point, even if you deleted a column.
  

  Flashback Table
  
  Just as the flashback query helps to retrieve rows of a table, FLASHBACK TABLE helps to restore the state of a table to a certain point in time - even if a table structure change has occurred since then. The following simple command will take us to the table state at the specified timestamp:
  
  SQL> FLASHBACK TABLE Employee TO 
             TIMESTAMP ('13-SEP-06 8:50:58','DD-MON-YY HH24: MI: SS');
  
  Reference - http://www.orafaq.com/node/872

  My DBA has sent me the following information;
  

  Oracle Metalink note  
  
  Limitations and Restrictions on Flashback Table :
  
  Flashback Table operations are not valid for the following type objects: tables that are part of a cluster, materialized views, Advanced Queuing (AQ) tables, static data dictionary tables, system tables, remote tables, object tables, nested tables, or individual table partitions or subpartitions.
  
  The following DDL operations change the structure of a table, so that you cannot subsequently use the TO SCN or TO TIMESTAMP clause to flash the table back to a time preceding the operation: upgrading, moving, or truncating a table; adding a constraint to a table, adding a table to a cluster; modifying or dropping a column; adding, dropping, merging, splitting, coalescing, or truncating a partition or subpartition (with the exception of adding a range partition).
  
  You cannot rollback a FLASHBACK TABLE statement. However, you can issue another FLASHBACK TABLE statement and specify a time just prior to the current time. Therefore, it is advisable to record the current SCN before issuing a FLASHBACK TABLE clause.

  Then my return of flame using DBA in this situation or not?

  I found that it is quite reliable. But when ANY site talking about a newly introduced feature, it must trigger at least one indicator "attention". There may be so many variables affecting the functioning of a new feature or is used unless you see a working example, you must create your own test case.

  As I said some things, like your question above, can be easily verified, so there is no reason to rely on any document to see if it works.
  >
  Is anyway to cancel this kind of thing or it is unrecoverable?
  >
  Almost nothing is "sunk", if you have the right type of backup. For a deleted column, you have an export of the table before the fall.

  Recommended for small changes DDL (for example related to an incremental update) is to take an export of the affected table.

• Creating a table to a csv file

  I use the JDeveloper 11.1.1.6.
  
  I'm looking to recover data to a .csv file and load it into a custom table made just for the data in the file.
  
  I managed to load the csv file in a data control with a Service URL data control. I wonder how to take data from the data control and place it in a Java object so that I can make the dynamic creation of sql create statement table. I know how to do dynamic creation - it's just to access the data of the data control to which I am at this point.
  
  If there is a better way to do it, I would be also open to it! Thank you!
