• indexed - color mode how to remove a custom color table color

  Hello

  I'm working on a bitmap to which I put my color mode to "indexed color Mode.  I created a custom color table and I added 9 colors.  I would like to delete one of these colors, but I can't find a way to remove a color from my existing custom color table or start with an empty custom color table so that I can add only colours I want.  If someone can tell me how to do either of these things, I'd be very happy.

  Thanks in advance,
  Paul

  I had the same problem. I'm not sure that you can remove colors. I just changed the color, I'm not one of the existing colors that I want. It does not hurt to have two colors of the same value in the table.

  Edit: This is what I warned you about in your other post.

• How to remove the changes to develop

  I have developed an image in LR and made two changes that showed in the history file. I did not like the result so deleted journal entries two history - but LR has left the image displayed with two changes applied! Guess I should have checked the help text before doing this, but what I read I thought it was how you reset the image.

  So, how do my image back (lol this is sort of related to another post where I was talking with copies of the negative not the negative itself). I know that I can not re - import image because LR will tell me it is already imported and will not create a duplicate. But I don't see how to remove these two changes to develop the image.

• How to find duplicate keys found when error ORA-01452: cannot CREATE a UNIQUE INDEX.

  Hi gurus,

  I fall for this stupid error

  "cannot CREATE a UNIQUE INDEX; duplicate keys found.

  
  

  It is that the Unique Index key is composed of multiple columns

  CREATE A UNIQUE KEY001AUTORISATIONS_APPORT ON TFT_AUTORISATIONS_APPORT INDEX

  (AUT_APPORTEUR, AUT_AGENCE, AUT_PRODUIT, AUT_OPTION, AUT_TARIF, AUT_DATE_AUTORISATION)

  Now,.

  My question is, how to find duplicates keys blocking Index creation?

  Thanks if you can help

  Run this query to display the list of the duplicates already existing.

  Select AUT_APPORTEUR, AUT_AGENCE, AUT_PRODUIT, AUT_OPTION, AUT_TARIF, AUT_DATE_AUTORISATION, count (1) as cnt

• Duplicate SQL - Unique Index-

  I have a table called SAMPLE:
  CREATE TABLE EXAMPLE
  (
  IDENTIFICATION NUMBER NOT NULL,
  NAME_N VARCHAR2 (50 BYTE) NOT NULL,
  BROWSE_TIME DATE,
  ENABLE CONSTRAINT PRIMARY KEY (ID) ID_PK
  );
  
  ALTER TABLE ADD CONSTRAINT ND_UK UNIQUE (NAME_N, BROWSE_TIME) EXAMPLE ACTIVE;
  
  I was issuing the instructions insert for the measure as follows:
  INSERT INTO SAMPLE (ID, NAME_N, BROWSE_TIME) VALUES (ID_SEQ. CURRENT_DATE NEXTVAL, 'NAME',);
  
  Session: emits the following value (ID, name, Date) as follows: 1, "NAME", October 1, 11
  Session b: emits the following value (ID, name, Date) as follows: 2, "NAME", October 1, 11
  Session c: emits the following value (ID, name, Date) as follows: 3, "NAME", October 1, 11
  
  Say the entire session active and validation is issued in the following order:
  C, A, B
  
  The approach described above is performed in a scenario highly concurrent / in real time.
  Sometimes, we could see the index accentuate was failed, but ended up with duplicate lines.
  
  The SQL is from the Java application, which could be wrong, how can we apply the unique index as the primary key.
  
  Database: 11G, v2

  >
  Yes, I wanted only the part of the date in the Date field.

  So instead of

  INSERT INTO SAMPLE (ID, NAME_N, DATE_D) VALUES (ID_SEQ.NEXTVAL, 'NAME', CURRENT_DATE);
  

  You must use

  INSERT INTO SAMPLE (ID, NAME_N, DATE_D) VALUES (ID_SEQ.NEXTVAL, 'NAME', trunc(CURRENT_DATE));

• How to add a column to an existing unique index?

  Hello
  
  I have a unique index defined on 5 columns in a table. I want to add a column more to the unique index. Is there one solution other than to drop and create the index?
  
  Also please let me know which is the ideal way to do it. The table has about 80 million documents.
  
  
  Thanks in advance,

  None...

  but creating the new index before your previous fall, the previous will be helping to create the new index faster.

  Hello

  For those who have faced the question above.

  Here is the Solution.

  1. Informatica PowerCenter Designer, place you in the SIL_Vert\Mappings folder and open the "SIL_ProductCategoryDimension_Hierarchy" mapping in the mapping Designer tool.
  2. Change the qualifier Source SQ_W_PRODCAT_DS to display the dialog box change Transformations and switch to the Properties tab.
  3. Select the name of the attribute processing Sql Query and edit the substitution of sql to change the status of outer join left in w_product_d as:
  4. DATABASE W_PRODCAT_DS
  5. LEFT OUTER JOIN W_PRODUCT_D PROD ON
  6. BASE. PROD_ID = PROD. INTEGRATION_ID AND PROD. CURRENT_FLG = 'Y '.
  7. Save the details and archive.

  
  

  The changes described above helped me load management command successfully.

• unique indexes

  Hello
  
  I am very confused about the unique index. Unique index contains duplicate key values? If so, how?
  
  Thank you for your cooperation.

  That's how Oracle handle 2 simultaneous transactions, trying to introduce the same key in a unique index. Note the use of the potential which means that Oracle will not allow to have keys duplicated in unique indexes.

• Unique and non-unique indexes

  
  Hello

  I have a unique index associated with no doubt. Unique and not unique indexes are used B tree architecture. But I want to know if I create a non-unique index on a column that contains unique data.

  When I query this table using this column, it scans each sheet or times found that value it scan stops and give us the result?

  00125 wrote:

  In a non-unique index, scans all the leaves... so what's the difference between full table scan and index ull. I went through a few articles they mentioned that a non-unique index to check with rowid. How she treated? I have clear knowledge in it.

  Please help me with this.

  Thanks in advance

  If you go through architecture index B-tree you could easily understand how indexing works. The picture here shows how a look of column datatype NUMBER indexed as / stored internally. You can imagine that your indexed column TST_COLA this will look like in the internal process. In the B-tree indexes, you have 3 main structures 1. 2 root. Branch 3. Leaves and the database retrieves lines by browsing through the root of index-> branch-> leaves. If the photo if we wanted to retrieve the row whose value indexed column = 25. First data goes to the root and finds that plugs is set to 25, then he Stoops to this particular branch of find what block sheet retains the value 25. More far away after finding the leaves block then goes to this block of sheets and research the special value of 25.

  If the index is UNIQUE, the database knows that there must be only one value, where it performs INDEX UNIQUE SCAN. If the index is NOT UNIQUE it should check all values in this block of leaves to find who all are 25 - in this case INDEX RANGE SCAN is done - as you must check not only value, but all values in this block of sheets - given that the values are not unique. As you can see it that the sheet block contains the long side of the value of the column ROWID, using this database rowid, then goes to the table to retrieve that particular line.

  Full table scan is a method of access where the database just to access the table directly (bypassing index structure) and analyze the ENTIRE table to satisfy the request.

• Unique index constraint Vs Unique

  Dear all,

  I just want to understand what is the difference between a Unique Index and uniqueness constraint

  I can create indexes like that, it duplicates will be blocked

  create table abhi_1 
  ( l_number number 
  )
  CREATE UNIQUE INDEX abhi_1_UK ON abhi_1
  (l_number);
  

  I can also use below syntax for duplicates blocking (index will be created internally)

  create table abhi_1 
  ( l_number number, 
  constraint abhi_1_UK UNIQUE (L_number)
  )
  

  Please specify,

  Hello

  I would use a unique constraint.  Allows you to create foreign key constraints referencing the single column.

  As you said, when you create a unique constraint, Oracle automatically creates an index for it if necessary.  You can explicitly set the attributes of that index (for example, the name and tablespace) If you wish.

• abstract unique index

  Hi guru.

  The idea

  Let's say there's a transformation g: X = > Y

  for the normal unique index this transformation is the mapping on his own game.

  Let's now if I have another transformation that I defined. g' which maps to another set.

  Will I be able to define a unique index as such.

  For example.

  I have a sample of 1 to 1000000 of id

  and I have this g'(id) function of probability which gives the value of 0 to 1

  For example, g'(1) = 0.67 and g'(10) = 0.67

  so in this case if I id = 1 in my table I wouldn't have id = 10

  How can I do this in Oracle?

• Accompanied by primary key to a non-unique index?

  Met a weird situation today. A utility, we set up which allows analysts to restore the data in their paintings, started failed when it attempted to drop an index. The index supported a primary key. Makes sense. But our script was supposed to be only an attempt to drop/recreate the nonunique indexes. It turns out that supported on the primary key index was not unique and to the best of my knowledge has emerged as follows:
  

  SQL> create table junk (f number(1));
  
  Table created.
  
  SQL> create index junk_ix on junk(f);
  
  Index created.

  What I can't understand, is how an index is not unique is to apply oneness. I thought it was the key to this process. I thought that perhaps an index with the 'SYS_123456' has be created, perhaps, but I couldn't find a:
  

  SQL> select object_name, object_type from dba_objects order by created desc;
  
  
  OBJECT_NAME   OBJECT_TYPE
  -------------------------------------------     
  JUNK_IX     INDEX
  JUNK     TABLE
  ...

  How the uniqueness is get applied in this case? It comes in Oracle 11.1.0.7
  
  Thank you
  -= Chuck

  It has always been like that. Oracle can and will use a non-unique index to apply a constraint to PK, the existing index just needs to have the columns PK as the leader or the columns in the index:

  SQL> create table t (id number, id1 number, descr varchar2(10));
  
  Table created.
  
  SQL> create index t_ids on t(id, id1);
  
  Index created.
  
  SQL> select index_name from user_indexes
    2  where table_name = 'T';
  
  INDEX_NAME
  ------------------------------
  T_IDS
  
  SQL> alter table t add constraint t_pk
    2  primary key (id);
  
  Table altered.
  
  SQL> select index_name from user_indexes
    2  where table_name = 'T';
  
  INDEX_NAME
  ------------------------------
  T_IDS
  
  SQL> insert into t values (1, 1, 'One');
  
  1 row created.
  
  SQL> insert into t values (1, 2, 'Two');
  insert into t values (1, 2, 'Two')

  Hello

  Search "CREATE INDEX" in the manual of the SQL language:
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/clauses002.htm#i1034458
  It has examples and explanations.

  You must create a unique constraint , which automatically creates a unique index.
  "CONSTRAINTS" are also in the manual of the SQL language.

  I think that its doable and I don't think that it should be feasible to all too since that would disrupt the structure of index completely. I think, you must delete the existing one to add a new column that is do a composite index.
