Index and lines in cluster

• Index and MATCH with several conditions

  Hi all! I hope I can explain what I'm trying to do here clearly. This is my first shot:

  In the table below "Office entry Worksheet - area 1" I am trying to insert a formula in column B which will result in an answer ' true / false ' and be used for conditional highlighting

  

  The first condition that must be met is that the checkbox in the table "Labor and material Checklist" column A or check, if it is not checked, then move to the next line. If the box is checked, then the following condition would need to index and match with column C of table "Office entry Worksheet - area 1" in column B. If there is a match in column C, then move to the next line of column B in the table 'labor and material Checklist '. This continues until there is a 'match', then highlight column B in the table "entry Office sheet - surface 1" in red (or something like "MISSING task")

  It is an estimate and the idea is to ensure that the Phases that are checked in the table "Labor and material Checklist" will not miss when you use the table "entry office map - zone 1".

  Thank you very much for your help!

• How to sort and distribution in cluster-table new dashboards?

  Hello

  I have three paintings of an integer (), B (timestamp) and C (double).

  Now, I want to convert them into a table of cluster. The Bay of cluster size is the number of different values in array A (here: two different values 1 and 2)

  If index 0 of the cluster array contains arrays of integers 1 and two with all values of the other two tables where the index of array A is 1.

  Index 1 of the cluster array contains arrays of integers 2 and two with all the values of the other two tables corresponding to the index of array A 2.

  How is that possible?

  Thank you and best regards

• Indexing and who should do it

  I work for a company that has a fairly large data warehouse Oracle that we use to store the SAP data dissemination (about 500 M of lines for some tables). Tables are not indexed and if I try to reach them on the query takes hours to complete. If the DBA needs to be proactive and create these indexes in order to reduce the load on the database?

  The team wants to load our 40 hours for 3 indices Department ADMINISTRATOR has already provided a script for. I'm naïve or y at - it something crazy to need 40 hours to implement 3 clues? I should mention that these tables is related to SAP and should be indexed to joined already IMO.

  I'm just trying to understand if I'm missing something.

  Thank you

  Creation of parallel indexing can reduce your time to create, but you must "alter index noparallel xyz" after its creation if you want really not parallel to this topic.

  Another impact on the creation of index how long does is how fast your hardware (processors, processor speed, speed of SAN etc.), but also what else is no running on the database in time using server resources.

  On an AIX Power 7-3 processor (quad core) production server it took me about 15 minutes to create an index on a table of 600 million lines running at the same time 8.

  On an AIX Power 5-4 Intel (quadruple-heart) test server it took about twice as long.  The SAN on production was super fast as well which had impact on how long it took.

  There are other factors that will affect the creation time.

  Specifically that I seriously doubt they can justify bill you for 40 hours.  It is unlikely that someone will run a script and then watching the screen for the next 40 hours waiting for the index to create... unless they are a bunch of clowns.  More than likely they run the script, go and do other things and periodically check to see if she has completed.

  Your IT team is having a laugh.  It should be fun to ask them to justify and to break the 40 hours.  minute to copy the script on the server, 30 seconds to go, 30 seconds to run the script.  39hrs, of 58 minutes watching the screen ready to create index at the end... Hmm... sounds fishy to me.

• (ORA-00955) conflict of naming for index and constraint when you use a unique index (.. desc,.. CSA)

  Hello

  indexes and constraints are in different namespaces, so it should be possible to give them the same name.

  In the following case that apparently does not work:
  

  create unique index orders_year_show_uq
    on orders (year desc, show_orders asc);
   
   alter table orders
    add constraint orders_year_show_uq unique (year, show_order);
  

  When I run these statement, I get a "SQL Error: ORA-00955: name is already used by an existing object". ""

  If I clean and I execute the same instructions as above with the only difference on the 2 line, using "asc year" instead of "year desc":

  
    on orders (year asc, show_orders asc);
  

  then it success.

  I can't explain it, you have an idea?

  Thanks in advance.

  Kind regards

  Giovanni

  First of all, you have show_orders in index and show_order in the constraint. I'll assume that it's a typo. Second, when you create constraint without index enhance the specification Oracle seeks indexes existing on the same set of columns in ascending order. If this index does not exist (and it's your case, since one of your columns to index is in descending order), Oracle tries to create one with the same name as the constraint. That's why you get ORA-00955: name is already used by an existing object. In general, you can specify explicitly the index name to force the Oracle by using the existing index. But it will not help you. If you issue

  ALTER table orders add unique constraint (year, show_orders) orders_year_show_uq using index orders_year_show_uq;

  You will get the ORA-14196: specified index cannot be used to apply the constraint.

  In any case, Oracle does not support using index DESC for PK/UK.

• spatial index and normal index

  Hi space specialists,.

  I have a question for spatial index performance and how Oracle manages queries that have a space and regular condition combined. We are on the Oracle 10 g Enterprise Edition Release 10.2.0.4.0 database

  Take a query like this one (not a real query but based on the type of query that is generated by ArcGIS):

  Select objectid

  attribute

  geometry

  table

  where mdsys.sdo_filter (geometry, mdsys.sdo_geometry (: gtype1,: srid1, null,: elem_info1,: ordinates1), 'querytype = window') = 'TRUE '.

  and attribute = value

  In our scenario, we have a lot of rows in the table (2 million), but we have only a few lines (2000) where attribute = value.

  It seems that there is a scenario where the performance is really bad. It takes 5 seconds for the query to return the results and you're just too slow for our needs. There is a spatial index on a geometry and a normal index on the field for the attribute. The plan of the explain command shows that both the spatial index and the index of the attribute are used.

  Of course, we can break to the top of the table in separate tables by object type. This would make the index space datamodel much more efficient, but at the expense of our current simple, abstract.

  Do you have suggestions on how we can improve performance without too much impact on our datamodel? Oracle for example has an option where you can create a spatial index on a subset of the data in a table?

  Thank you!

  Rob

  Do not know whether or not the following works for your case:

  use the column range-key attribute to create a partitioned table Beach and then create a local spatial index.

• Indexes and constraints

  Hi guys!
  
  I did a little test and now I do not understand the result. Please explain to me the following:
  
  (1.) I created the following table emp1
  
  < pre >
  CREATE TABLE emp1
  (
  EmpNo NUMBER CONSTRAINT emp1_pk PRIMARY KEY
  USING INDEX
  (
  CREATE UNIQUE INDEX emp1_idx ON emp1 (empno)
  )
  );
  < / pre >
  
  2.) now, I interviewed user_indexes and user_constraints
  
  < pre >
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  NORMAL SINGLE ACTIVE P EMP1_PK EMP1_IDX
  < / pre >
  
  3.) after that I disabled the emp1_pk constraint and I Redid the same query
  
  < pre >
  ALTER TABLE emp1 DISABLE NOVALIDATE CONSTRAINT emp1_pk;
  
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  EMP1_PK NULL NULL NULL P DISABLED
  < / pre >
  
  So far so good. I got disabling of this constraint is okay to delete the corresponding index. But in the following example, the corresponding index would not be deleted.
  
  < pre >
  CREATE TABLE emp2
  (
  EmpNo NUMBER
  );
  
  CREATE UNIQUE INDEX emp2_idx
  ON emp2 (empno);
  
  ALTER TABLE emp2
  ADD CONSTRAINT emp2_pk PRIMARY KEY to the AID of INDEX emp2_idx;
  < / pre >
  
  2.) now, I interviewed user_indexes and user_constraints
  
  < pre >
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  NORMAL SINGLE ACTIVE P EMP2_PK EMP2_IDX
  < / pre >
  
  The result of this query is the same as emp1_pk. But at the next step, the results differ.
  
  < pre >
  ALTER TABLE emp2 DISABLE NOVALIDATE CONSTRAINT emp2_pk;
  
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  NORMAL EMP2_PK UNIQUE P DISABLED EMP2_IDX
  < / pre >
  
  That's what I did not understand. Emp1_pk has been disabled and the corresponding index emp1_idx was abandoned. Emp2_pk has been turned off but the corresponding index has not been deleted. Can someone explain to me please, the difference between the example 1 (emp1_pk) and example 2 (emp2_pk).
  
  Concerning

  Hello

  In the first example, Index was done by primary key, and when we disable the primary key, it also drops the corresponding index.
  But in the second example, the Index is created on the column separately and then the primary key is created. Now that there is already an index on the primary key column will use this existing index and when we disable the constraint this index will not be droppped because it was not created by primary key. It was only used by primary key.

• Switching between microphone and line-in in the Realltek Sound Manager

  Ok.
  Now I know where the Realtek Sound Manager, and I can control the parameters of the microphone and speakers.
  But how can I switch between microphone and line-in?
  At the moment I don't see a line of component option snap at all. Is it because it's a kind of auto detect and the opportunity every time I connect something?
  Everyone knows this, or has some experience in this regard?
  Cordially in advance
  Frans

  Sorry but I don't understand what exactly you want.
  You have built in mic or you can use the external microphone connected to the mic-in port.
  When the external microphone is connected a resident will be disabled.

  The question is: what do you want exactly and for what purposes? Please explain what is the reason for this switching between mic and line-in port?

• Satellite M307 - a lot of points and lines on the screen

  I bought this new pc in China there is a half year

  But if I don't touch it, it will be OK. I think this may be caused by the connection between the screen and the main physical system. Please contact me: [email protected]

  Hello!

  I agree with you it's a connection problem or the display is faulty.

  I think your laptop should be still under warranty then I would go to a local ASP.

• Programmatically set the size of a table control (not the number of col and lines)

  Hi all

  I am trying to create a little VI, in which the user selects the number of columns and rows in a table, and after clicking on a button 'OK', the table control is displayed in the control panel (to be filled in by the user). To do this, I use the nodes property to the number of columns and lines. I have no problem with that.

  However, I want to "limit" the size of the control table (control of himself, not the dimensions of the table) and make use of vertical and horizontal table, the scroll bars. I want to avoid it is that passes type 100 user and 100 lines and appears a huge table control.

  I could tho this by using an array instead of an array, via the node property "size", but I would use an insead table a table.

  Thank you very much

  Daniel

  With a table control, you cannot set the display size to be anything other than a multiple of a complete cell.

  If you are limited to a number of lines and columns.  If you want to resize with more control you also need to resize the control within the Bay, accessible via the property 'picture Element '.

  Another option (but seems huge exaggerated) is to place your table in a secondary and set the size of the secondary to the size you need and enable scrollbars for her.  It is not an option that I would choose but if it helps...

  Have it, your description of your user interface sounds not very intuitive.  How the user knows at any time exactly what cell they access if they have to scroll backwards?

• Why is my screen blurry and lines undulate on the sides? It also keeps the glitter!

  Why is my screen blurry and lines undulate on the sides? It also keeps the glitter!

  Is your very large monitor, like an old TV or flat, as perhaps a few inches thick?  If it is very deep (front to back), you have an old style monitor, and they need to be demagnetised every now and then. Look on the monitor for the menu button and navigate until you find an icon like a horseshoe with a bar slash through it (or like a magnet) and select it.  All wavy and colorful display for one minute and then went back to normal. Also, make sure that all the cables between the monitor and your computer are firmly connected at both ends, even if you have a thin screen.

  If you have a laptop, try to turn the screen and see if the blur changes.  If so, you might have a connector loose inside and may need to be considered at a repair shop. =(

  Best luck!
