• Adding constraints to an existing table

  Hello
  
  I consulted the books forum, documentation, internet and text but cannot find the correct SQL command to add constraints to an existing table
  
  Obviously I would
  
  ALTER TABLE ADD CONSTRAINT Whitemeat Turkey
  
  But what comes next is confusing, the Whitemeat column values can be any value other than dinner, gravy, pumpkin or Sauce
  
  Any help would be great
  
  Thank you

  See the [Manual of the SQL language | http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_3001.htm#sthref5176] for the correct syntax.
  The condition after the keyword CHECK must be in brackets.
  To add a CHECK constraint to an existing table, I think that you must change the column.

  ALTER TABLE turkey
  MODIFY  ( whitemeat     CONSTRAINT     turkey_whitemeat_ck
                   CHECK          ( whitemeat NOT IN ( 'Dinner'

• Partition on existing Tables

  Hello
  
  I want to archive a database due to too much data into DB everymonth, so I have to delete the records from the previous month, which is about 4 million.
  
  Can someone give me idea to delete records as soon as possible. My opinion is to create the partition on the table and drop the partition once he becomes older.
  But if I want to introduce the partition then I have to create a partition in an existing table. So please give me the best way to introduce the partition of the existing table.
  
  It would really help that may suggest meanings.
  
  Thank you
  
  Spengler

  Here is an example

  CREATE TABLE my_table (
    id           NUMBER,
    description  VARCHAR2(50),
    create_date date
  )PARTITION BY RANGE (create_date)
  (PARTITION id_id0 VALUES LESS THAN (TO_DATE('26/08/2009', 'DD/MM/YYYY')) TABLESPACE users,
   PARTITION id_id1 VALUES LESS THAN (TO_DATE('27/08/2009', 'DD/MM/YYYY')) TABLESPACE users,
   PARTITION id_id2 VALUES LESS THAN (TO_DATE('28/08/2009', 'DD/MM/YYYY')) TABLESPACE users,
   PARTITION id_id3 VALUES LESS THAN (TO_DATE('29/08/2009', 'DD/MM/YYYY')) TABLESPACE users,
  PARTITION id_id4 VALUES LESS THAN (TO_DATE('30/08/2009', 'DD/MM/YYYY')) TABLESPACE users,
  PARTITION id_max  VALUES LESS THAN  (MAXVALUE) TABLESPACE users);
  

  -Insert the sample data

   INSERT INTO my_table  VALUES (0, 'ZERO',sysdate);
  INSERT INTO my_table  VALUES (1, 'One',sysdate+1);
  INSERT INTO my_table  VALUES (2, 'Two',sysdate+2);
  INSERT INTO my_table  VALUES (3, 'Three',sysdate+3);
  INSERT INTO my_table  VALUES (4, 'Four',sysdate+4);
  COMMIT;
  

  -You can run these queries to check the output.

  select * from my_table;
  select * from my_table partition(id_id0);
  select * from my_table partition(id_id1);
  select * from my_table partition(id_id2);
  select * from my_table partition(id_id3);
  select * from my_table partition(id_id4);
  select * from my_table partition(id_max);
  

  -Split partition

  ALTER TABLE my_table SPLIT PARTITION id_max AT (TO_DATE('01/09/2009', 'DD/MM/YYYY'))
  INTO (PARTITION id_id5 TABLESPACE users,PARTITION id_max TABLESPACE users);

• 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

• How to add the new column in existing table to our desired location?

  How to add the new column in existing table to our desired location?

  For example, I have to add the new column 'course' before the salary column in the emp table.

  I think the best way is to add the column at the end of the table and create a new view with the order of the columns...

  Another option...

  places the data into a temporary table and recreate the table with the correct order of the columns, and then insert data to the table from the temporary table

  Refer

• Add the cluster to an existing table in oracle

  Is it possible to add the cluster of an existing table? For example...

  I have a table:

  CREATE TABLE table_name)

  t_id number PRIMARY KEY,

  t_name varchar2 (50));

  Cluster:

  CLUSTER to CREATE my_cluster

  (c_id NUMBER) SIZE 100;

  Y at - it a command such as: ALTER TABLE t_name add CLUSTER my_cluster (t_id); or something like that?

  Because I want to table to look like this:

  CREATE TABLE table_name)

  t_id number PRIMARY KEY,

  t_name varchar2 (50))

  My_cluster (t_id) CLUSTER;

  And drop all the tables isn't really what I want to do.

  Thank you

  No,

  It is the reverse:

  A table can be stored as a segment of memory (the common way) or in a cluster.

  Will not be part of the table "in the cluster", but other parts outside.

  Please create a new table in the cluster and insert your data here.

  Sorry,

• 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.

• Existing table: Add a field that must be unique or null, is - permit?

  Hello

  I'm working on Oracle Utilities applications. I'm not a guru on the development of the database.

  There is an existing table with the following fields:

  1. DocVersion
  2. UIDContract
  3. StartTime
  4. StopTime
  5. Volume

  The first 3 fields are used to the PK.

  The function of this table to follow how much volume is linked to a Doc version and now with the change of the volume associated with the new SelNumber field.

  Now I have to make a change and I want to add a new field: SelNumber.

  There are two situations when a record is written to this table:

  1. existing situation is always necessary: then the SelNumber field is not filled in = NULL
  2. The new situation has added: the SelNumber field is not NULL.

  What's not now, it is that, in the new situation, the first free fields have the same value, only the SelNumber is different. So the first time a record is added to the table. But the next this record is replaced with the new value.

  I can't add the SelNumber field to the PK because in the first situation is NULL and a field of pharmacokinetics cannot be null, or...?

  So how can I resolve that I can add a record to the table the PK fields have the same value, but the value SelNumber is different, and in the situation, the SelNumber is null? Is it possible to make a unique constraint on the SelNumber field that has the value null or a unique number? Or is it a stupid thought?

  
  

  The alternative is I think, to create a new table, but on the other hand, I think that it should be possible!

  Please can someone help me with this problem I am facing in?

  Nico

  Hello

  I don't think you can do what you want with a Primary Key constraint.

  You can, however, create an index based on a single function, where the index values are all NULL when SelNumber is set to NULL:

  CREATE UNIQUE INDEX table_x_uk

  ON table_x

  (NVL2 (SelNumber, Docversion, NULL)

  NVL2 (SelNumber, UIDContract, NULL)

  NVL2 (SelNumber, StartTime, NULL)

  SelNumber

  );

  It will not not no constraint on the lines where SelNumber is set to NULL, but, if SelNumber is not null, then the combination of all 4 columns must be unique.

  Sorry, I can't test it now.

  Thank you

  What would be the best way to add a partition to an existing table?

  Is there a simple documentation for example?

  Was it something you were ask in an interview?

  You cannot add a partition to a table unless this table is a partitioned table.

  The table is already partitioned? If so, after the DDL.

  The Oracle documentation has examples of adding partitions to a table that is already partitioned

  Adding a Partition to a partitioned Table range

  Use of the ALTER TABLE ... ADD PARTITION statement to add a new partition at the end 'high' (the point after the last existing partition). To add a partition at the beginning or in the middle of a table, use the SPLIT PARTITION clause.

• Adding rows or cells to existing Tables in Dreamweaver CC

  Dear Sir/Madam,

  Why can't I add additional cells or columns to an existing table?

  I have a database that I've frequently updated, but I note that since I upgraded my software from Studio MX 2004 to Adobe Dreamweaver CS5.5 (try now Dreamweaver CC) and the table options (such as adding rows/columns) are not available.

  What is the best way to list the alphabetical links. Should I just list people without a table or I can use what I already designed (without having to create a new page, since it will age to enter all the data again)?
