• Increase the performance of the Insert using e DBlink

  Dear friends,
  
  I try inserting 4 Lakes records in a table using the DB - Link.It is taking a lot of time (1 hour) to insert the records, is there another way to increase performance.
  It's my insert statement.
  
  Insert / * + APPEND PARALLEL NOLOGGING * / in target_table
  Select * from source_table@dblink_name

  Nowhere in this thread I see the following:

  1. the hardware (servers) and the operating system.
  2. WEP (which is the speed of the network and the bandwidth?).
  3. oracle version number.
  4. any real time
  5. the time inserts take when it is not pushed through the db link but run locally.
  6. explain the plan.
  7. a DML statement.
  8. information about the indexes on the target table.
  9. information about constraints on the target table.
  10. information on the triggers on the target table.
  11. the evidence that the target is, in fact, a table and not a view or another object type.

  I don't see how someone can do more than ask the OP for more information about the fact that what was provided is totally inadequate to make a recommendation.

• dblink and serialization

  Thank you in advance, I perform a task in oracle instance that is running a procedure in another instance oracle (different machine) via dblink and a local procedure, like this:

  use1. MyProcedure@machineSTG (v_code_id, V_DATE, v_outfile, v_outcacode, v_outcatype);  -procedure of dblink

  User2.my_package.do_something (v_outcacode, v_outcatype, v_outfile); -local procedure, inside reading remote table inserted by procedure dblink

  commit;

  Is it guaranteed that the procedure provided for in the remote computer runs first and finish before the local procedure begins to run? I need this series as the local procedure implementation also read remote tables, inserted by the first procedure (dblink) thank you.

  Yes.

• insert into the table based on the difference in line (or using less)

  Hello

  Oracle Version: 11g

  Operating system: Solaris 10.

  I was wondering if it is possible to insert data in a table based on the operator 'less' Please?

  We have a very large table in a database, we moved to a different database. The table is cleared by a line for a certain range of dates, and we wondered if it is possible to insert this line of data in the remote database using the difference of rank between the two tables.

  Here's the query that we are running:

  SELECT ID , TO_CHAR (creation_datetime, 'yyyy-mm-dd')
  from TABB10 
  where TO_CHAR (creation_datetime, 'yyyy-mm-dd')='2014-03-18' 
  minus 
  SELECT ID , TO_CHAR (creation_datetime, 'yyyy-mm-dd')
  from TABB10@TABB_LINK.APDB00 
  where TO_CHAR (creation_datetime, 'yyyy-mm-dd')='2014-03-18'
  

  TO_CHAR (CR ID

  ---------------------- ----------

  2.4111E + 17-18 / 03 / 2014

  Any ideas please?

  Thank you

  If I don't get me wrong, you can insert as below

  INSERT INTO REMOTE_TABLE@DBLINK

  SELECT ID, TO_CHAR (creation_datetime, "yyyy-mm-dd")

  of TABB10

  where TO_CHAR (creation_datetime, 'yyyy-mm-dd') ='' 2014-03-18

  less

  SELECT ID, TO_CHAR (creation_datetime, "yyyy-mm-dd")

  of TABB10@TABB_LINK. APDB00

  where TO_CHAR (creation_datetime, 'yyyy-mm-dd') ='' 2014-03-18

  Thank you

  Dates isn't a varchar2 format. Somewhere in your code your dates are converted to a varchar2, and you do not specify an explicit date format.

  You should NOT rely on a default date format, because it can be changed by changing the operating system, or even by Oracle in a new release.

  Has nothing to do with sysdate but with flawed code, caused by lack of knowledge developers.

  You must have the corrected code.

  Either stop the conversion in varchar2, or specify a date format.

• Trying to understand NVARCHAR with UTF8

  Hey everybody,

  Hoping to help understand the behavior NVARCHAR and others; I've not used it much in the past.

  I'm on: 11.2.0.3.0

  Background:

  -existing database:

  WE8ISO8859P1 NLS_CHARACTERSET

  NLS_NCHAR_CHARACTERSET UTF8

  Most of the columns use 'normal' VARCHAR2 data type, and I'm generally okay with that.

  However, they used NVARCHAR2 data type for the data in the column "french" (although the WE8ISO8859P1 character set they use supports french. * sigh *)

  In any case... is not even with a french character. I think this is the 'Smart' quote of the window.

  Question:

  Running a query to get a picture of the 'bad' production data, shows the character (a quote any: "don't know not if making it will transfer all correctly"), such as code ASCII 49810 or 49809 (we see both)

  In an attempt to install a 'test' in development to happen again and I can't seem to do.

  create unwanted table (ID, vv nvarchar2 (100));

  insert into junk values (1, chr (49809));

  insert into junk values (2, chr (49810));

  insert into junk values (3, chr (96));

  commit;

  SELECT id, vv, dump junk (vv);

  Developer SQL (via Windows) and SQL * Plus (via Unix), see the same thing:

  ID VV                                       DUMP(VV)

  ---------- ---------------------------------------- --------------------------------------------------

  1?                                        Typ = 1 Len = 2: 0.145

  2?                                        Typ = 1 Len = 2: 0,146

  3 `                                        Typ=1 Len=2: 0,96

  3 selected lines.

  In both cases, the 'smart' quotes don't to not correctly store and appear to be "converted".

  I'm not really sure what's going on, but I was trying to figure out how to set my NLS_LANG, but don't know what to put in?

  On Unix, I tried:

  export NLS_LANG = American_America.UTF8

  However, which amends the code of '? ' to 'Â' (re-directed the entire script, the same code: 145/146 stored, so still lose it during the insertion, I guess)

  So I suspect it's a case of this character not actually supported by UTF8, right?

  For SQL Developer, not so lucky... I put a Windows env variable NLS_LANG even above, however, it still shows in SQL Developer as a box empty.

  Issues related to the:

  (1) just to check, I'm even not sure that these characters (IE 49810 and 49809) are based in fact on UTF8? (did some research, but could not find anything that could confirm it for some..)

  (2) how (good) set NLS_LANG for SQL Developer and what to put in so I can read/write characters in those pesky NVARCHAR fields?

  (3) how to enter (even with force)-49809 characters or 49810? (for testing purposes only! )

  (FYI: this is especially for me learning.) The 'solution' to our initial problem is to convert these bad characters of 'normal' quotes: IE code ASCII 39. Of course, be able to properly test the update would be really very nice, this is why I need to 'force' the entry of some bad data in dev

  Thank you!

  Answers:

  (1) just to check, I'm not even sure that these characters (IE 49810 and 49809) are based in fact on UTF8 ? (did some research, but could not find something that could confirm it for some..)

  Yes, this is valid UTF-8 character codes. However, their meaning is not what you expect. 49809 = UTF - 8 0xC291 = U + 0091 = PU1 control character (USE PRIVATE ONE). 49810 is in UTF - 8 0xC292 is U + 0092 = PU2 (TWO of USE PRIVACY) control character

  (2) how (good) set NLS_LANG for SQL Developer and what to set it so I can read/write characters in those pesky NVARCHAR fields?

  Developer SQL does not read NLS_LANG at all. You must not do anything to read and write content NVARCHAR2 using the data of a table editor tab or read the content with a worksheet query. Additional configuration is required to support particular NVARCHAR2 literals in SQL commands. However, you can still use the UNISTR function to encode Unicode characters for type NVARCHAR2 columns.

  (3) How to enter (even with force)-49809 characters or 49810? (for testing only for purposes!)

  Not really possible keyboard because they are control codes. You can insert only with SQL using CHR or UNISTR.

  (4) what is the real problem?

  The real problem is the direct configuration called application insert these characters paired with the fact the application inserts NVARCHAR2 data without mark it as such in the corresponding API Oracle (OCI, Pro * C, JDBC). NLS_LANG is set up as. WE8ISO8859P1 for the application and the database is WE8ISO8859P1 as well. When a Windows client application written for Win32 API ANSI passes these Oracle quotes, the quotes are encode as 0 x 91 / 0 x 92. However, this encoding for the french quotation marks is correct in the Windows 1252 code Page (name of Oracle: WE8MSWIN1252), not in ISO-8859-1 (name of Oracle: WE8ISO8859P1). As character set NLS_LANG and database are the same, no conversion happens to the codes. On the side of the database, Oracle considers that the target column is of type NVARCHAR2, so it converts to WE8ISO8859P1 in UTF8. However, the interpretation of codes does not at the moment and UTF8 codes that result are 0xC2 0 x 91 and 0xC2 0 x 92 (ISO-8859-1 encoding codes control PU1 PU2) instead of the correct 0xE2 0x80 0 x 98 and 0xE2 0x80 0 x 99 (encoding Cp1252 characters SINGLE LEFT quotation MARK and quotation MARK SINGLE RIGHT).

  Solutions:

  1. the best solution is to migrate the database to AL32UTF8 and discard the NVARCHAR2 data type. You will be able to store any language in any column VARCHAR2.

  2. less forward-looking but a simpler solution is to migrate the database character value WE8MSWIN1252. If additional characters are French, get rid of the NVARCHAR2 data type, because it is just extra cost.

  3. the minimum solution is to migrate the database by WE8MSWIN1252 character and keep the NVARCHAR2 columns.

  If the data to be inserted more French and quotes, you should definitely go with the first option. The third solution would work after changes appropriate to the use of the application of the API of the Oracle client.

  In any solution, the NLS_LANG should be replaced by. Application WE8MSWIN1252 (but this will not only help).

  Thank you

• A selection in a table in a table in a different database?

  Is it possible run a select a table in which the recovered data could be inserted into another table in another database and even if in another server?

• Dealing with errors due to newly added/removed columns

  DB version: 11 g
  
  
  I don't know if I created a post unnecessarily large to explain a simple problem. Anway, this is here.
  
  Asked me to encode a package for archiving.
  
  We will have two schemas; The original schema and a schema of the Archive (connected via a DB link)
  

  ORIGINAL Schema -------------------------> ARCHIVE Schema
                 via DB Link

  When the records of some tables in the ORIGINAL schema meet the archiving criteria (based on the number of days old, Status Code etc.), it will be moved ("archived") to the schema of the ARCHIVE using the INSERT syntax
  

  insert into arch_original@dblink
  (
  col1,
  col2,
  col3,
  .
  .
  .
  .
  )
  select col1,
  col2,
  col3,
  .
  .
  .
  .
  from original_table

  The original table and the table of archive has the same structure, except that the Archive table has an additional column called archived_date that records only when a record got archived.

  create table original
  (
  col1 varchar2(33),
  col2 varchar2(35),
  empid number
  );
  
  
  create table arch_original
  (
  col1 varchar2(33),
  col2 varchar2(35),
  empid number,
  archived_date date default sysdate not null
  );

  We have tables with many columns (there are a lot of tables with more than 100 columns), and when all column names are explicitly mentioned as the above syntax, the code becomes huge.
  
  Alternative syntax:
  
  So I thougt of using the syntax

  insert into arch_original select original.*,sysdate from original;  -- sysdate will populate archived_date column

  Even if the code looks simple and short, I noticed a downside to this approach.
  
  Disadvantage:
  For the next version, if developers decide to add/drag a column in the ORIGINAL table in the original schema, this change should be apparent in (ARCHIVE) DDL script of the diagram of the archive_table as well. It is virtually impossible to keep track of all these changes during the development phase.
  
  
  If I use

  insert into arch_original select original.*,sysdate from original;  

  syntax, you will realize that there is change in the structure of the table only when you encounter an error (because of lack/news column) in the Runtime. But, if you have all the column names are explicitly as

  insert into arch_original@dblink
  (col1,
  col2,
  col3,
  .
  .
  .
  .
  )
  select col1,
  col2,
  col3,
  .
  .
  .
  .
  from original_table

  Next, you will encounter this error when compiling itself. I prefer the error due to a lack/new column when compiling itself rather than at run time.
  
  While the guys do you think? I shouldn't go to

  insert into arch_original select original.*,sysdate from original; 

  syntax due to the inconvenience above. Right?

  VitaminD salvation,

  Yes, something like that. Only, I meant to use it as a code generator to produce static sql to use in your archiver plan. I didn't use dynamic sql.

  Start with something simple, to generate lists of columns to insert and select. Decide if you want to generate complete instructions, procedures or the same package.

  For beginners to do something like you suggest

  select ',' || column_name from cols where table_name like :your_table order by column_id;
  

  Out of use allows you to easily create your insert into... Select in the statement. Once you feel able to this topic, consider as much as your taste.

  But my point is still. Use it as a static sql.

• SQL formatting question

  I have a PL/SQL package that essentially the archiving with INSERT in SELECT statements. It looks like
  

  insert into archive_table@dblink
  (col1,

  )
  select from original_table
  (col1,

  .
  )

  For huge tables, I just get a list of the columns in the CREATE table statements (view SQL in PL/SQL developer). But this INSERT statement seems very long because a single column (and his coma) will there be per line.
  
  The code looks like very long (vertically)

  insert into archive_table@dblink

  )
  select from original_table
  (

  col7,col8,.......
  )

  I used SQL in PL/SQL developer beautifier. But it did not work. Is there any tool you are aware of that can do this?

  Go to the menu Tools and then "Preferences...". ».
  In the UI section, click on "Beautifier PL/SQL ' and then click on the Edit button to modify your settings of beautifier.

  In the DML tab change your settings to 'Fit' for insert and select, maybe updated, according to your need.
  You can also adjust the width of the screen in the general tab, under the option of "right margin".

  I would recommend saving your settings in a file so you can reuse it in all cases that you may need to change computers or something.

  Edit: Oops I replied to the wrong post by habit, Alex.

  As a pointer, VitaminD, your insert command has an incorrect syntax in the select part where there should be something like below instead of columns after the name of the table.

  insert into archive_table@dblink
  (col1,
  col2,
  col3,

  Hello

  FORALL has a limitation, it does not work on a DBLink.
  Operations block (such as FORALL) are used to minimize the change between PL/SQL and SQL context engines.
  For remote database operations, there is no change of context SINCE each DB link must open is no new connection.
  In your scenario, it will be much better to use an approach to PULL rather than PUSH. This way you can get to use FORALL as well.

  As in:
  Having a procedure in DB2 (instead of having it in DB1). This way used inside FORALL DML will not have a DBLink

  I hope that helps!

  See you soon,.

• Remote index not used with INSERT in the local table on dblink

  Hi all
  
  I don't know if anyone has come across this problem before, but for some reason any the remote index remains unused ONLY* in the insertion on the local database operation. Let me explain this pseudo-device code
  
  insert into LOCAL_TABLE
  Select / * + index_combine (alias_remote_tab IDX_LOG_DATE) * /.
  trunc (log_datetime),
  Count (*)
  of REMOTE_TABLE@DBLINK alias_remote_tab
  When trunc (log_datetime) = trunc(sysdate-1)
  Trunc Group (log_datetime);
  
  where:
  REMOTE_TABLE is a table partitioned on log_datetime (monthly)
  IDX_LOG_DATE is an index of bitmap of based on a valid function on log_datetime created in the trunc (log_datetime)
  local database: 10 gr 2
  remote database: 11 GR 1 material
  OS: windows (both)
  
  More funny thing is when I just run the select query independently on the only both local and remote, the index is used. I checked by printing the command explain for the select query plan. But when I prefix the query with the insert lose all hell breaks and local database plays the ignorance about the index. The command for the insert query explain plan has no mention of the index even when I explicitly place the index indicator in the select part of the query.
  
  If this should not be simple enough for ORACLE? Am I missing something here?

  Jonathan describes the details and the reasons for the behavior you see in following blog post http://jonathanlewis.wordpress.com/2008/12/05/distributed-dml/
  Your SELECTION is performed remotely (filtering and grouping) and sends only the (relatively) small results via dblink local database while the in an INSERTION, filtering only occurs at the remote and data site (relatively) important are sent via dblink to the local database, the consolidation takes place.
  You can give a try to the approach proposed by michaels2. If the approach from the view result grouping and filtering which will take place in the remote database, you will see improved performance.

  PS BTW, if the sql code that I suggested to check the plane, in my previous post using an index, then the cause of your performance issue is certainly not due to the index not used and is due to the amount of data transferred to dblink.

  Hello

  Looking at your SQL it loks like you're not joining to the PROJECT table (where the word dreaded CARTESIAN?):

  Your code:

  JOIN PROJECTS P ON PS.PROJECT_SEQ = PS.PROJECT_SEQ 
  

  ... I think this should probably be...

  JOIN PROJECTS P ON P.PROJECT_SEQ = PS.PROJECT_SEQ 
  

  ....??

• Insert the string xml in a clob column. ??

  https://drive.Google.com/file/d/0BwAVQqYmX0-zMHZiS1F0SVdOMmc/view?USP=sharing

  DECLARE
          v_clob CLOB := to_clob('xml string from local file'); --pls. download xml file from above url;
          stmt NVARCHAR2(500) := 'INSERT INTO TEST(XMLDATA) VALUES(:x)';
  BEGIN
          EXECUTE IMMEDIATE stmt USING v_clob;
  END;
  

  If I use xmltype so I can use XMLType (bfilename ('test_dir', '"Data.xml" '), nls_charset_id ('AL32UTF8'))

  but I have to use clob for storing the xml string. because oracle xmltype cannot correctly parse these xml data. ;

  Google search for 'oracle insert clob from the file' would you find this answer fairly quickly.

  You don't need to use dynamic sql statements.

• Insert and update records to MySQL from Oracle

  Hello

  Our application will be insert/update new records in the Oracle database, but I need to insert/update new records in the MySQL database. Oracle and MySQL tables have the same columns.

  Right now, we intend to create DBLink between Oracle and MySQL. The question is to know how to write code to insert/update new records to MySQL from Oracle. I'm a new guy in this area.

  Please give us some examples of code, thanks!

  With Oracle, you should be able to just write the same thing as usual, except for the include link database when you reference the table for example your SQL

  insert into tablename@mysqldblink...

  updating of the game tablename@mysqldblink...

  Services gateway through the database link (odbc drivers or anything else that is used) must make the most of the necessary conversions for you.
