• Create the Table as and hybrid columnar Compression

  I'm looking to connect to tables help to create the table as I had a question about columnar Compression hybrid. For the test, I found that the uncompressed daata will be approximately 10 to and compressed data will be around 1 TB. I anticipate compress the table when the table to create as an instruction and wanted to know in what order Oracle forge do compression, that is, the table will be created then Oracle will compress the data or will the compressed table that the table will be created. The motivation behind the question is to see how much storage I need to complete the operation.
  
  Thank you

  If you are using
  create table xxx compress for query high what to choose...

  While the data will be compressed before insertion, so in your case, it will use about 1 TB of disk space

• compression of the table

  Hi guys,.

  I try to compress the table. Then I connect via Oracle SQL Developer > right click > storage > compress. All right.

  But does not change the size of the table.

  Y at - it a command to say: 'start compression for my table1 now?

  More than 50,000 rows in my table.

  Thank you!

  Compression of the data in a table does NOT change the size of the table.

  It increases just the available space in the table.

  Oracle shall never voluntarily return disk space after that she acquired it.

  Oracle is designed to reuse free space.

  Hi all

• Question from beginner on the fusion of the Recrords in the Table

  This question is about question 10-b of merger on page 3-41, it says:
  (page 3-41 "Oracle Database 10g SQL Fund. II Vol.1")
  
  Merge the data into the EMP_DATA table that is created in the lab last in the data in the table emp_hist. assume
  EMP_DATA external table data corresponds to the EMP_HIST of table, update the email column
  table EMP_HIST to match the row in the EMP_DATA table. If a row in the EMP_DATA table is not
  match, to be inserted in the tables of EMP_HIST lines are considered as corresponding whenever his first and
  family name are the same.
  
  For me, this issue is built wrong. First of all in the last lab we have not been asked to create EMP_DATA. Secondly, EMP_DATA is empty.
  Thirdly, this question asks us to merge into the table EMP_HIST while EMP_DATA is empty.
  
  Table EMP_HIST currently copied data from the employees table. Structure EMP_HIST:
  
  FIRST NAME VARCHAR2 (20)
  LAST_NAME NOT NULL VARCHAR2 (25)
  EMAIL NOT NULL VARCHAR2 (45)
  
  EMP_DATA table is empty. I created it as follows:
  
  create or replace directory emp_dir
  like 'F:\emp_dir ';
  
  drop table emp_data;
  
  CREATE TABLE emp_data
  (first name VARCHAR2 (20))
  , last_name VARCHAR2 (20)
  , email VARCHAR2 (30)
  )
  EXTERNAL ORGANIZATION
  (
  TYPE oracle_loader
  Emp_dir default DIRECTORY
  ACCESS SETTINGS

  NOBADFILE
  NOLOGFILE
  FIELDS
  (first name POSITION (01:20) TANK)
  , last_name POSITION (22:41) TANK
  CHAR POSITION (43:72) by email)
  )
  LOCATION ('emp.dat'));
  
  Back to our question, I've done the merger as follows:
  
  merge into e emp_hist
  with the help of emp_data d
  on (e.first_name = d.first_name)
  When matched then
  game update
  Select = d.last_name,
  e.email = d.email
  When not matched then
  Insert values (d.first_name, d.last_name, d.email);
  
  I get this error:
  
  Error report:
  SQL error: ORA-29913: error in executing ODCIEXTTABLEOPEN legend
  ORA-29400: data cartridge error

  29913 00000 - "error in the execution of %s legend".
  * Cause: The execution of the specified legend caused an error.
  * Action: Examine the error messages take appropriate measures.
  
  On the other hand, I said I'm going to try this:
  
  merge into emp_data d
  using e emp_hist
  on (d.first_name = e.first_name)
  When matched then
  game update
  d.last_name = select,
  d.email = e.email
  When not matched then
  Insert values (e.first_name, select, e.email);
  
  I get this error because the external table's final after its creation (no update, insert, delete authorized) as far as I know:
  
  Error report:
  SQL error: ORA-30657: operation not supported on external organized table
  30657.0000 - "operation not supported on external-organized table".
  * Cause: User attempted on the operation on an external table which is

  What happens if I want to import large data set in the external table?

  Hmm, external table is just a definition on how you want to watch a file as a table in the database. Think of it as a tool to import data.

  1. first of all, have a ready file (with data).

  2. create an external table using the format of the file.

  3. now you should be able to see the data when you do this. Select * from my_external_table.

  4. now, create an ordinary table where you want the data to insert permanently.

  5 insert into permanent_table select * from my_external_table.

  I hope this helps.

  Hello

  First of all, are you sure that the nested tables generated during the registration of the scheme?

  You must annotate the schema with xdb:storeVarrayAsTable = 'true' and use the option genTables-online true for registration.
  Then you should see something like this:

• size of the table with the compress and no compression

  Hello
  I have a table takes up 35.5 GB of space with 120 mill inside files.
  I thought that compress would save me a lot of space, so I did.
  
  Here's how I compressed:
  I created a separate tablespace and in the new tablespace, I created several database, files, each file is to have 2 GB.
  then insert all the records out of the original table to the new then,
  I ran the query below see also size
  
  SQL > select ((blocks*8192)-(blocks*avg_space)) / 1024/1024 MB size of "", empty_blocks,.
  2 avg_space, num_freelist_blocks

  in above query first a 2 GB on all resultant space after compress and the second is the original with NO size to compress.
  
  I have a question are these calculated dimensions are reliable. ?
  because the utility compress oracle inserts data in blocks in the database files.
  If these blocks are to halfway filled and left empty and then go to the next block and so forth.
  
  Is above sizes to account for empty blocks... ?
  
  I don't know how to explain it
  Help, please

  I don't see where you use compression. So I don't know what you mean by compress. If you mean native compression, use something like:

  SQL> create table tbl as select * from dba_source;
  
  Table created.

• A question about the conservation of fields (hour, min, sec) time DATE type in the table on the changes of NLS_DATE_FORMAT

  Hello

  Oracle version: 12.1.0.1.0 - 64 bit

                    OS:   Fedora Core 17 X86_64

  My question is about the conservation of fields (hour, minute, second) time DATE type in the array on NLS_DATE_FORMAT changes.

  Take the following test case:

  SQL> create table tmptab(dateval date);
  
  Table created.
  
  SQL> alter session set nls_date_format = 'yyyy-mm-dd hh24:mi:ss';
  
  Session altered.
  
  SQL> insert into tmptab(dateval) values('2014-01-01 00:00:00');
  
  1 row created.
  
  SQL> insert into tmptab(dateval) values('2014-01-01 10:00:00');
  
  1 row created.
  
  SQL> commit;
  
  Commit complete.
  
  SQL> select * from tmptab;
  
  DATEVAL
  -------------------
  2014-01-01 00:00:00
  2014-01-01 10:00:00
  
  SQL> alter session set nls_date_format = 'yyyy';
  
  Session altered.
  
  SQL> select * from tmptab where dateval > '2014';
  
  no rows selected
  
  SQL>
  

  I don't understand why it returns nothing. The second test case above insert statement inserted a line with 10 as the value for the time of the DATE field column dateval.

  Accordingly, while comparing this with the literal '2014' (which based on the new value of NLS_DATE_FORMAT = "yyyy" is implicitly converted to DATE), shouldn't the above query returns the line 2014-01-01 10:00 ?

  I mean, I changed the NLS_DATE_FORMAT but data from time in the table fields are preserved and that's why they should normally be taken into account in the comparison of date.

  What I'm trying to say is that for me (Please correct me if I'm wrong), no matter what NLS_DATE_FORMAT configuration is the following test

  SQL> select * from tmptab where dateval > '2014';
  

  is the same thing that

  SQL> select * from tmptab where dateval > to_date('2014-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss');
  

  And because the line 2014-01-01 10: 00:00 in the tmptab table. The following test

  2014-01-01 10:00:00 > to_date('2014-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
  

  evolves normally true (beucase of TIME = 10 on the left side of the test) and therefore this line must be returned which is not the case in the test above.

  You kindly could you tell me what I misunderstood?

  Thanks in advance,

  This is the price for the use of implicit conversions. Implicit DATE conversion rules are not as direct as it can be assumed. In your case, all you provide is year as date format. In this case date implicit conversion rules assumes that month in the current month, day 1 and time as 00:00:00.

  SQL > alter session set nls_date_format = "yyyy";

  Modified session.

  SQL > select to_char (to_date ('2014 "), ' mm/dd/yyyy hh24:mi:ss') twice;

  TO_CHAR (TO_DATE('20)
  -------------------
  01/08/2014-00:00:00

  SQL >

  So, when you start:

  Select * from tmptab where dateval > '2014 '.

  Oracle implicitly converts date using "YYYY", which translates as August 1, 2014 '2014'. That's why your quesry returns no rows.

  FROM table_x

  WHERE expire > = TRUNC (SYSDATE)

  Maturity AND< add_months="" (trunc="" (sysdate)="" ,="" 2)="" +="">

  ;

  I hope that answers your question.

  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

  Explain, using specific examples, how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• missing parenthesis in insertion into separate lines select the table from the other table

  Hello

  could you help me with the following question?

  I have the following tables

  CREATE TABLE table1)

  ID varchar (12),

  col2 varchar (10),

  COL3 varchar (10),

  level varchar (10))

  CREATE TABLE table2)

  Id2 varchar (12)

  A varchar (10),

  B number (1)

  CONSTRAINT PRIMARY KEY PK (ID2, is));

  INSERT INTO table2 (ID2, A, B) SELECT ID, col2

  MAX (CASE WHEN level = "level 1" then 1

  level = 'level 2' then 2

  Level = 3 then 'niveau3') as colIN3)

  FROM table1 GROUP BY ID2, a.;

  the first table have duplicates as follows:

  Id2 COL2 COL3 level

  A1 pepe football level1

  A1 pepe football level2

  A1 pepe football level1

  A1 pepe basket level2

  A1 pepe pingpong level3

  the output should be selected with unique key (ID2, col3) lines and the level must be the greatest.

  Id2 COL2 COL3 level

  A1 pepe football level2

  A1 pepe basket level2

  A1 pepe pingpong level3

  The output of the script tells me the following messages:

  -lack of right parenthesis referring to the max function.

  Thanks adavance.

  Kind regards

  Hello

  Remember the ABC's of the GROUP BY:

  When you use a GROUP BY clause or in an aggregate function, then all in the SELECT clause must be:

  (A) a ggregate function,

  (B) one of the expressions "group By."

  (C) adding to C, or

  (D) something that Depends on the foregoing.  (For example, if you "GROUP BY TRUNC (dt)", you can SELECT "TO_CHAR (TRUNC (dt), 'Mon - DD')").

  To ask him, there are 5 columns in the SELECT clause.  The last one is a function MAX (...); It is an aggregate, is not serious.

  The first 2 columns are also named in the GROUP BY clause, so that they are well.

  The other 2 columns, country and internal_Id do not match any of the above categories.  These 2 columns cause the error.

  There are many ways to avoid this error, each producing different results.  You could

  • remove these 2 columns in the SELECT clause
  • Add these 2 columns in the GROUP BY clause
  • use the aggregation such as MIN, 2-column functions
  • remove the country from the SELECT clause and add internal_id to the GROUP BY clause
  • remove the internal_id from the SELECT clause, and add countries to the GROUP BY clause
  • ...

  What are the results you want?

  Whenever you have a question, please post a small example of data (CREATE TABLE and INSERT statements) for all the tables involved, so people who want to help you can recreate the problem and test their ideas.  Also post the results you want from this data, as well as an explanation of how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Questions on the tables of materialized views and MV newspaper

  Hi all
  
  Have some questions about Materialized View.
  
  (1) once the materialized view reads the records from the table MLOG, reviews the MLOG get purged. fix? or is that not the case? In some cases, I see still (old) records in the MLOG table even after updating MV.
  
  (2) how the table MLOG distinguishes between a reading which comes from a MV and a reading that comes from a user? If I execute manually
  "Select * < table MLOG > ' could get record of the table MLOG redacted all the same way as it does after a refresh of MV?
  
  (3) one of our MV updates crashes intermittently. Based on the events of waiting I noticed that it was a 'db file sequential read' against the main table. Finally I had to put an end to the update. I don't know why it was sequential reading on the main table when she should be reading the table MLOG. Any ideas?
  
  (4) I saw 'file db scattered read' (full table scan) usually on tables, but I was surprised to see 'db file sequential read' against the table. I thought sequential read occurs normally against the index. All the world has noticed this behavior?
  
  Thanks for your time.

  (1) once all the registered materialized views have read a particular line in a trunk of materialized view, it is removed, Yes. If there are multiple materialized views that are based on the same newspaper, they would all need to refresh before it would be safe to delete the log entry for MV. If one of the materialized views is no incremental updating, there may be cases where the log purge automatically.

  (2) No, your query does not cause anything be served (although you wouldn't see something interesting unless you get to implement a lot of code to analyze change vectors stored in the journal). I don't know the exact mechanism used by Oracle has been published, if you could go through and draw a session to get an idea of the moving parts. From a practical point of view, you just need to know that when you create an updatable materialized view fast, it will register as interested especially newspapers MV.

  (3) it depends on what is stored in the log of MV. The update process may need to recover specific table columns if your log stores just the fact that the data for a particular key changed. You can specify when you create a materialized view that you want to store specific columns or include the new clause values (with the NEW VALUES INCLUDING). It is perhaps beneficial (or necessary) for the refreshment quick process, but it would tend to increase the storage space for the materialized view log and increase the cost of the maintianing the materialized view log.

  (4) sequential reads on a table are perfectly normal - it just means that someone looking for a block of data in the table (i.e. looking a line in the table of ROWID based on the ROWID in an index or a materialized view log).
