• Create a view with a column change journal

  Hello

  I have the following table:

  create table test1)

  number of site_number

  date of change_date,

  number of area_ha);

  insert into test1 values (1, TO_DATE('1/1/2007','DD/MM/RRRR'), 20);

  insert into test1 values (1, TO_DATE('1/1/2008','DD/MM/RRRR'), 30);

  insert into test1 values (1, TO_DATE('1/1/2009','DD/MM/RRRR'), 25);

  insert into test1 values (2, TO_DATE('1/1/2007','DD/MM/RRRR'), 50);

  insert into test1 values (2, TO_DATE('1/1/2008','DD/MM/RRRR'), 60);

  insert into test1 values (2, TO_DATE('1/1/2009','DD/MM/RRRR'), 60);

  insert into test1 values (3, TO_DATE('1/1/2007','DD/MM/RRRR'), 20);

  insert into test1 values (3, TO_DATE('1/1/2008','DD/MM/RRRR'), 25);

  insert into test1 values (3, TO_DATE('1/1/2009','DD/MM/RRRR'), 30);

  What I want to do is to have a view based on the table above which includes a column of change (change_log below) based on the anterior surface (area_ha) for each specific site_number. For example in the first line site_number 1 has increased the area of 20 hectares on the 01/01/2007 to 30 hectares on the next change_date for this site that 01/01/2008. How this could be done?

  SITE_NUMBER	CHANGE_DATE	AREA_HA	CHANGE_LOG
  1	01/01/2007	20	NO CHANGE
  1	01/01/2008	30	ADDED SPACE
  1	01/01/2009	25	DELETED DOMAIN
  2	01/01/2007	50	NO CHANGE
  2	01/01/2008	60	ADDED SPACE
  2	01/01/2009	60	NO CHANGE
  3	01/01/2007	20	NO CHANGE
  3	01/01/2008	25	ADDED SPACE
  3	01/01/2009	30	ADDED SPACE

  I am using oracle 11g R2

  Select site_number,

  change_date,

  area_ha,

  sign of case (area_ha - lag(area_ha,1,area_ha) over (partition by order of change_date site_number))

  When 1 "AREA ADDED.

  When-1 then "ZONE DELETED."

  Another 'NO CHANGE'

  end change_log

  of test1

  order of site_number,

  change_date

• Definition of the erroneous view importing view with text column expression

  Hello
  
  I use SQL DM v 3.3.0.744.
  When importing a view designer and the column has a column expression, a frowned upon request is created.
  Example generated by the designer:
  CREATE OR REPLACE FORCE VIEW VIEW6
  + (COL1) +.
  AS SOME substr (col1, 55, 1)
  OF TAB1 T1
  The following text is generated by DM:
  CREATE OR REPLACE VIEW VIEW6 (COL1)
  IN SELECT
  COL1 COL1;
  The following remarks:
  -l' column expression is not repeated.
  -the underlying table/view is not included.
  
  Can you trigger a bug for that?
  
  Joop

  Hi Joop,

  Can you trigger a bug for that?

  Our knowledge of the designer is limited, so it's better create you a service request and describe how you created this view and/or provide an example in the form of exported the repository designer example.
  Maybe that's the best export to do as a text file.
  The same applies for this Migration of Designer: bad alias for the table/view used in views

  Hello

  U go.

  1 the interface:

  "Put a filter in your 1 on attr.name = array ' PRODUCT_CODE.

  In the map target TABLE2
  SERVICE_ID = TABLE1. SERVICE_ID
  PRODUCT_CODE = TABLE1. ATTR_VALUE

  Use SQL IKM append control

  Interface 2:

  "Put a filter in your 1 on attr.name = array ' PROVIDER '.

  In the map target TABLE2
  SERVICE_ID = TABLE1. SERVICE_ID
  PROVIDER = TABLE1. ATTR_VALUE

  Do SERVICE_ID as KEY (when you click the column target in properties, you can see KEY under properties of the target column) and use the incremental update of the IKM Oracle.

  PS: I assume that Oracle as the source and target.

  And you can refer to the documentation,

• Derived from the existing columns

  Hello
  
  How to create a new column that has derive data from another table on this logic:
  
  Table A

  2 homeless
  3 SDS
  
  Table B
  ID name tableA_ID

  ID name tableB_name
  1 SD dsf
  2 sdf of
  3 SDS
  
  basically just try to merge 2 tables with a 1-1 relationship. I tried to fill in the data of table B in A, but by making an inner join and when I query the data, does not return a row ID 3 in table a.

  In model MDB make outer join. Make sure that you select next outdoor table.

• Create table works, create materialized view only - long column names?

  Hello.
  
  I have no probs creating a table as well: -.
  CREATE TABLE blah
  (
  DEVICE_ID
  )
  in select
  "Device_ID" AS DEVICE_ID
  "of"sum" Device"@ed_link_3
  where "Device_ID" < 5;
  
  
  But when I try to create a materialized view:
  Blah1 CREATE MATERIALIZED VIEW
  (
  DEVICE_ID
  )
  < various materialized view parms >
  in select
  "Device_ID" AS DEVICE_ID
  "of"sum" Device"@ed_link_3
  where "Device_ID" < 5;
  
  It fails with errors: -.
  ORA-04052: error occurred when searching to the top of the remote object Aggregate.Device@ED_LINK_3
  ORA-01948: length of the name of the identifier (31) exceeds maximum (30)
  
  Is there a way to get around this?
  Is the problem with the columns of the remote table of device, which I do NOT need to import to have column names that are longer than 30 characters?
  
  For now, I want only the Device_ID column which is a simple 9 characters long.
  
  Oh, and the remote database is MySQL.
  I'm uncomfortable with the < parms of materialized view > as they work fine when I choose a different remote table with only short column names.
  
  Thank you.

  To my knowledge, you have the option
  (a) create view (with shortened column names or only with desired columns if they are already less than 30 char limit) side of mysql
  (b) use dbms_passthrough to force the analysis to be done on mysql (as in the example provided by SY here use dbms_passthrough to create a view )
  However, I prefer to stick to one), because with dbms_passtrhough, you retrieve row by row.

• Table with 300 columns

  While talking with a friend, he told me that sometimes he uses tables with 300 columns that will be available only once for the extraction of information. For me, it's a little strange because 300 columns looks like a large number of columns for me...
  
  Have tables with columns as is common practice in the data warehouse? If Yes, can you explain to me on what situations, this can happen and how often?
  
  Concerning

  We have tables with columns of cca 150.

  You should know that we don't talk to relational systems which are standardized. Its common practice when building data warehouse. Number of columns in the tables will depend on the complexity and the size of your warehouse and the number, size and complexity of your source systems.

  Point is that even now, when the data warehouse is "done", we still add/remove columns changes to warehouse such as changing the source systems.

  Anyone had this problem and if so found a work around?
  Thank you.

  Leland,

  The error was caused by apply you the mask of YYYY format a number field. I changed a switch of dates for a list of selection and gave you an LOV query that would give you the current year, the last 3 years and the next two years. You can adjust that, according to the needs. I also put the definition LOV to accept other values incase you had a value in the db that was not in the LOV I've defined.

• Create the view with the dynamic from clause

  Hi all
  
  you might have some ideas to help me out of my problem I just "created myself" ;-)
  
  I have an unknown quantity and not constant of the tables using the same structure of the table and I have a main table
  that contains all the names of these table types. Now, I want to create a unique view that contains all the columns in each table
  and an extra column name containing the name of the corresponding table.
  
  I found a solution for this but only if I knew that all the table names while creating my view.
  
  Here is what I currently have:
  
  master_table:
  TABLENAME ID
  1 table_01
  2 table_02
  
  
  table_01:
  ID NAME
  1 eins
  zwei 2
  drei 3
  
  
  table_02:
  ID NAME
  1 a
  2 two
  3 three
  
  
  I think 'tab1tab2' on these 2 table looks like this:
  
  ID NAME TABLENAME
  1 table_01 eins
  2 zwei table_01
  3 drei table_01
  1 a table_02
  2 two table_02
  3 three table_02
  
  
  I have reached this point of view with:
  
  CREATE OR REPLACE VIEW TAB1TAB2 ('ID', 'NAME', 'TABLENAME')
  AS
  SELECT id, name, 'table_01' AS table_01 FROM tablename
  UNION
  SELECT id, name, 'table_02' AS tablename FROM table_02;
  
  
  
  Is it possible to create as many select statements and union that I entered (tablenames) into my master_table to achieve the same results as my opinion hard?
  
  Thank you very much in advance for your help
  
  Best regards
  
  Majo

  create or replace view v_alltables
  Select * from v_all;

  These two statement contradict each other in some way, Don't they?

  path ID number name 'id', varchar2 (20) 'name' of the path) x;

  the column names are case sensitive - try

    id number path 'ID' , name varchar2(20) path 'NAME' ) x;
  

  assuming that the names of the columns are named like that.

  Original title: scams?

  I continue to receive calls from numbers not available with an Indian accent saying that they are from the Technical Department of windows and I have a problem with my computer. Normally, I just say that I don't have and hung up. Today, I took a little further and he said that they discovered that I had loads of malware/viruses etc and that they could identify with them. I was obviously very suspicious because he seemed to have my correct Windows ID number and with care on 'Run' he told me to type things like cmd eventviewer and inf where he referred to a file 1394.pnf. I stopped while he asked remotely to access my computer. However, I got a phone number 01916450337 and his P786000 id I noticed that many people are posting on your forum-is this another one of those scams?

  Continue to put the phone down. They are all crooks.

  They get you to open Event Viewer, because there are words such as 'critical' and 'error' along the this.

• How to select columns, that we need a table with pivot

  Hello

  How can I select only the required columns that I need the table

  My goal is to keep everything in one line

  Database: 11.2.0.2.0

  I have a table called Table Agent

  create the table AGENT_DETAIL

  (

  agent_id NUMBER (20) not null,

  agent_type_code VARCHAR2 (10) not null,

  agent_type_prefix VARCHAR2 (10) not null,

  Type_Code VARCHAR2 (10) not null,

  type_prefix VARCHAR2 (10) not null,

  last_modified DATE not null

  )

  INSERT INTO agent_detail VALUES

  (29709, ARE ',' OFFICE ',' DNSWEB ',' AGTDETAILS', SYSDATE);

  INSERT INTO AGENT_DETAIL VALUES

  (29709, ARE ',' OFFICE ',' DNSNATID ',' AGTDETAILS', SYSDATE);

  INSERT INTO AGENT_DETAIL VALUES

  (29709, ARE ',' OFFICE ',' DELIVERY ',' AGTDETAILS', SYSDATE);

  INSERT INTO AGENT_DETAIL VALUES

  (29709, ARE ', 'OFFICE', "WEBUSAGE", "WEBUSER" SYSDATE);

  When you query it against the table

  SELECT * FROM AGENT_DETAIL;

  	AGENT_ID	AGENT_TYPE_CODE	AGENT_TYPE_PREFIX	TYPE_CODE	TYPE_PREFIX	LAST_MODIFIED
  1	29709	RE	OFFICE	DNSWEB	AGTDETAILS	22:14:15 12/09/2015
  2	29709	RE	OFFICE	DNSNATID	AGTDETAILS	09/12/2015-22:15:26
  3	29709	RE	OFFICE	DELIVERY	AGTDETAILS	09/12/2015-22:21:37
  4	29709	RE	OFFICE	WEBUSAGE	WEBUSER	10/12/2015-09:27:52

  Because my goal is to put everything in a single line instead of get in 4 rows

  My query is like that

  (select *)

  the Dungeon of pivot (min (TYPE_CODE) AGENT_DETAIL (last dense_rank command by LAST_MODIFIED) for TYPE_CODE in ('DNSWEB' as the WEB)

  'DNSNATID' as

  NATIONAL,

  'DELIVERY' AS

  DELIVERY,

  "WEBUSAGE" AS WEBUSAGE

  )

  ))

  Result:

  	AGENT_ID	AGENT_TYPE_CODE	AGENT_TYPE_PREFIX	TYPE_PREFIX	WEB	NATIONAL	DELIVERY	WEBUSAGE
  1	29709	RE	OFFICE	WEBUSER				WEBUSAGE
  2	29709	RE	OFFICE	AGTDETAILS	DNSWEB	DNSNATID	DELIVERY

  Is it possible to get everything in one record, I know that I have two type_prefixes different (WEBUSER, AGTDETAILS)

  But all I want to see my data is like this

  Agent_id Agent_type_code Agent_type_prefix WEB WEBUSAGE NATIONAL DELIVERY

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

  RE OFFICE DNSWEB DNSATID DELIVERY WEBUSAGE 29709

  Hello

  When you use SELECT... PIVOT, the result set contains 1 row for all the distinct combinations of the values of all columns except columns mentioned in the PIVOT clause.  If you want to ignore some columns completely, then let the PIVOT operated at a "table" that does not include the.  For example:

  with RELEVANT_AGENT_DETAIL as

  (

  Select AGENT_ID, AGENT_TYPE_CODE, AGENT_TYPE_PREFIX, TYPE_CODE, LAST_MODIFIED

  of AGENT_DETAIL

  -where--if you filter, put it here

  )

  Select *.

  of RELEVANT_AGENT_DETAIL

  Pivot (min (TYPE_CODE) Dungeon (last dense_rank command by LAST_MODIFIED))

  for TYPE_CODE in ('DNSWEB' as WEB

  'DNSNATID' as NATIONAL

  'DELIVERY' as DELIVERY

  "WEBUSAGE" as WEBUSAGE

  )

  )

  ;

  If you are lazy or trying to be cute, maybe you can give the columns unwanted some lazy jobs in the PIVOT clause, like this:

  Select *.

  of AGENT_DETAIL

  Pivot (min (TYPE_CODE) Dungeon (dense_rank last order by LAST_MODIFIED)

  TYPE_CODE

  TYPE_PREFIX

  )

  for TYPE_CODE in ('DNSWEB' as WEB

  'DNSNATID' as NATIONAL

  'DELIVERY' as DELIVERY

  "WEBUSAGE" as WEBUSAGE

  )

  )

  ;

  But this makes the code confusing and may be difficult to maintain.
