• How to create a view in the DB table for some servers

  Hello
  
  We need create a country table which will contain data for countries.
  
  I want to create it in such a way that it will be common for all servers - but as a point of view. not the real table, only the data and views do not change.
  
  How can I do?
  
  Thanks in advance

  Are you sure you want to say 'tablespace '? A tablespace is a collection of data files. It has nothing to do with the privileges of the object, object namespaces, etc. I'm guessing that you mean that you have two schemas, OBITUARIESCS and ADVERTISEMENTCS. A schema is a collection of objects of database belonged to a particular user. A single table can exist in spaces of multiple tables (assuming it is partitioned). Different schemas can have an infinite number of tables with the same name in the same table. The database schema is the namespace for objects such as tables.

  Assuming that you have two schemas in your database, you can create a table of COUNTRIES in the OBITUARIESCS schema. You can then grant SELECT access on the table to another user, ADVERTISEMENTCS, i.e.

  GRANT SELECT ON country TO advertisementcs
  

  You can then ask questions (but not change) the COUNTRY code of the property of ADVERTISEMENTCS table

  SELECT *
    FROM advertisementcs.country
  

  If you want to be able to remove the prefix in the schema, you can create a synonym. In the ADVERTISEMENTCS schema

  CREATE SYNONYM country
    FOR advertisementcs.country
  

  and then when the code of the property of ADVERTISEMENTCS wants to query the countries table, it can just

  SELECT *
    FROM country

• Create procedure upsert (name of the existing table, incoming table name)

  Is it possible to create a procedure that makes a merge (upsert) with only two parameters:

  1. Existing Table name - name of table that will have data merged into it.
  2. Incoming Table name - name of the table that has developed data day/news.

  The method would be:

  1. Use primary keys on the "existing" table as the condition links
  2. Fact and update if exists and insert new
  3. no record
  4. no clues
  5. no removal clause

• referential integrity with a view to the parent table

  Is it possible to create a foreign key that uses a view as the parent table?
  
  CREATE TABLE one
  + (id NUMBER CONSTRAINT a_pk PRIMARY KEY, +)
  name VARCHAR2 (32));
  
  CREATE TABLE b
  + (name of the b_pk VARCHAR2 (32) CONSTRAINT PRIMARY KEY, +)
  address VARCHAR2 (32));
  
  CREATE VIEW b_view AS SELECT * FROM b;
  
  ALTER VIEW b_view ADD CONSTRAINT b_view_pk PRIMARY KEY (name) DISABLE NOVALIDATE;
  
  ALTER TABLE an ADD CONSTRAINT a_fk
  B_view (name) REFERENCES of FOREIGN KEY (name);
  
  "After issuing the last alter statement I get the error: ' ORA-02270: no unique or primary key corresponding to this list of columns.
  
  If I use just the table b of referential integrity, everything works. Is this just a limitation of the use of the view with a PK defined as disable novalidate? Is there a workaround to use the view?
  
  Thank you
  mcslain

  AFAIK, you can create constraints on views, purely for the sake of documentation.
  Sense: these constraints are never implemented, they must be defined using the NOVALIDATE keywords to DISABLE.

  And since these constraints, say the b_view_pk in your case, are DISABLED/NOVALIDATE, you cannot have a foreign key (ENABLED), which points to them.

  Pouvez have you a foreign key pointing at them is DISABLED/NOVALIDATE too, however.
  But I bet it's not what you want.

• Add the constraint not NULL in the existing table that has null values

  Hello

  I want to add a constraint not null to and an existing table, but the table already contains values null in this column.

  EMP

  Emp_id name

  1 axada

  2

  3 sdkdd

  Here is already the data IE 2 empid is Null as name. I must add a fool of constraint not null which new values will not be null, but I don't want to change the data of exisitng alreadt which is null.

  Hello

  "The opposite": NOVALIDATE does not validate the data that is ALREADY in the table, but do not allow the insertion of a NULL value.

  Have you tried my sample code?

  CREATE TABLE MaTable (x NUMBER PRIMARY KEY, y NUMBER);

  INSERT INTO myTable VALUES (1, 123);

  INSERT INTO myTable VALUES ( 2, NULL );

  INSERT INTO myTable VALUES (3, 456);

  ALTER TABLE mytable MODIFY (y NOT NULL NOVALIDATE );

  INSERT INTO myTable VALUES (4, 678);

  INSERT INTO myTable VALUES ( 5, NULL );

  SELECT * FROM MyTable;

  '2' line was inserted with null before the creation of the NOT NULL constraint, this line remains "as what" at the end of the trial.

  '5' line trying to insert a NULL value after creating the NOT NULL constraint, which is denied.

  Best regards

  Bruno.

• Compress all the existing table ain dat

  Hello
  
  We use oracle 11.2.0.3 and wish to evaluate the performance of compression in terms of reduction of time takes to reports aganis the tables run.
  
  Had a quick serach and can see alter table compress but speaks only of data inserted/updated updated after the operationexecute of compress is compressed.
  
  Do not want to have to create a separate, compressed table and replace other table with that.
  
  Is it possible to compress all the existing dat aof existing table?
  
  Also could what kind of performance gain magntitudes we expect performance report using the compression compared to identical but uncompressed tabel?
  
  Also it is a data warehouse and the large fact table already has the default compressed index bitmpa.
  
  Tlamking on the compression of the table here.

  Depending on your hardware, you can use alter table move and change the index on a table of size fairly decent rebuild in less than 10 minutes, but if you really make the look works online in the dbms_redefinition package. See the manual of the PL/SQL Package and Types, then look at the note support for Oracle at the following address:

• How to stop refreshing materialized views if the source table is null

  What is your question? Is this an academic question or you have a real problem that needs to be addressed?

  If you have a problem producing the DDL for the materialized view, and information about the type of discount that has been set up for this. Is there a newspaper view materialized on the underlying tables?

  The simple answer to your quest is to use UPDATE them on REQUEST and check the base tables before making a manual

• Adding data to the existing Table

• Create table replaces the existing table in mssql

  In a program that allows us to update our sites, we use the function 'create an array' of MS SQL to create missing tables in databases.
  
  Thousands of time we used it, if a table already exists with the same name of the table in the create table MS SQL survey command an error.
  
  In fact, MS SQL documentation indicates that only if you include the optional 'replace' command, will be a replaced existing table.
  
  But today, we used this program on a new host, that we are trying, and the create table command actually did replace an existing table with a new table, delete all the records from the old table.
  
  I'm trying to understand what this would allow the settings at the server level.
  
  This is the code we use:
  
  < CFQUERY NAME = "recipe" DATASOURCE = "recipe" dbtype = "ODBC" username = "" #ruser # "password =" #rPASS #">"
  Create table recipecats)
  RecipecatID int IDENTITY(1, 1) NOT NULL PRIMARY KEY,
  recipecatdescription NVARCHAR (50) NULL)
  < / cfquery >

  Are you sure that this is not just to create another table with the same name, but one
  different owner?

  I saw the strangeness (it's probably just weird for me because I am ignorant)
  of what is happening), I can READ a table owned by another user without
  calling the name of the table with its owner, and when I go to CREATE a table
  of the same name, it is actually created as my current user and subsequently when
  you ask the name of the full table, I get the results of one, is not new
  the former. If I'm right in the name of the table, I can ask both/either. Kind
  way similar CF hunting around different scopes when you aren't eligible one
  reference to a variable.

  Also, your code should probably be testing to see if the table exists
  before you try to create it anyway. "Just try and catch.
  "If it errors" is not considered as 'test' if there is

• Report Generation Toolkit - keep the existing table

  Previously, I used the TXT (CSV) files to store test data. Some tests to run for 1000 hours and collect anywhere from a few lines of thousands of data from more than 100,000 rows of data. Using this approach, I have to write macros VBA to parse and format of these data, which are very time-consuming. I'm looking to try to use the LabVIEW Toolkit for generation report (GTA) to write directly in an Excel spreadsheet and do some steps on the fly as the VBA macro, to help reduce the processing time and manual work on the analysis of the data.

  However, my concern is that sometimes one must quit school essay through a long trial and then continue and add data to the existing data. I don't see how using the GTA. I guess you would have to locate the latest data from the spreadsheet... using a TXT file, LabVIEW is done automatically. In Excel, I use VBA code like this:

  RowMax is SheetRD.Cells ("A", SheetRD.Rows.Count). End (xlUp) .row

  The GTA has features like that, or I'll have to call a macro and then work with the returned value of RowMax?

  You can use Excel get last Row.vi of the specific generation of report-> Excel-> General Excel palette. Add 1 to get the line empty next.

  . . export of table TABLE_NAME_1234
  EXP-00056: ORACLE error 8103

  the error indicates that the object no longer exists...
  
  What could be the reason?
  
  
  Thank you

  May be at the start of the export of the table, the table has been truncated by some other session in the database.

  Can you try to resume the export and return.

• I bought a view with the vista operating system model - however I got a bluescreen etc. and I need to reinstall VISTA

  However, as it's an exdisplay I don't have books or CDs and do not have a backup disk.  How can I fix my blue screen?  When I can not open in Safe Mode, I clearly need a VISTA installation disc but how can I get on these without having to buy AGAIN

  Hello tamster2708,

  Whatever your machine a display model of the manufacturer "must" give you an option to restore your PC to factory conditions. This is done in two ways. (1) a Windows DVD is provided. (2) the operating system is on a hidden partition on the hard drive of the system. Chances are yours is this one.

  As you have no literature tell you what keys press when to start your machine which will allow you to access the recovery partition, I suggest you to contact the store you purchased your machine from and to ask their technical support how are you suppose to go on the restoration of your machine to factory conditions.

  You might alos visit PC manufacturers Web site and look to the top of the brand and the model of your machine, just in case they have a downloadable guide. If you can download a user guide, browse and search for "restoring your PC back to factory conditions" this will then tell you how to restore program.

  If your machine is not a copy of the operating system on a hidden partition then ask the shop how you are going to get an OS DVD, ensuring that you point out that 'they' should have provided a way for you to restore your system should any problems arise.

  This forum post is my own opinion and does not necessarily reflect the opinion or the opinion of Microsoft, its employees or other MVPS.
