• To create an interactive report in the apex by selecting from multiple tables

  Hi, I am creating an interactive report by selecting from multiple tables.

  SELECT w.FIRST_NAME as name, w.SURNAME as name, i.ROAD Road, i.DATE_OF_INC as DATE_OF_INC, S.STATEMENT as a STATEMENT OF Declaration

  JOIN THE

  WITNESS w

  ON w.witness_id = s.FK1_WITNESS_ID

  JOIN THE

  Incident I have

  WE

  i.incident_no = w.FK1_INCIDENT_NO

  JOIN THE

  user_station ps

  ON ps.station_id = i.nearest_station_id

  JOIN THE

  the user in.

  WE

  in. STATION_ID = ps.station_id

  WHERE po.officer_id = 1

  by I continue to encounter this error "the report query requires a unique key to identify each row. The supplied key cannot be used for this query. Please change the report attributes to define a unique key column. "ORA-01445: cannot select ROWID from where sample, a join without key preserved table view '

  So I googled around and found that in the attibutres tables report, I need to change the "LINK" COLUMN so first, I changed "Link to custom target", but the report is so I changed it to "Exclude link Clolumn" again, the report didn't report and I STILL got a blank page with only the tabs.

  I wonder you can not create a report by selecting from multiple tables?

  If you can please I need your help.

  Thank you

  You can, but in this case, it might be easier to build your report tables that are joined Oracle views and then build your report out of the newly built sight...

  Or wrap a selection around your selection with joins, and then make the where clause on the external selection...

  Thank you

• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

  WITH THE HELP OF)

  SELECT t1.id

  t1.column1

  t1.column2

  t2.column3

  t2.column4

  FROM table1 t1

  JOIN table2 t2 ON t1.id = t2.id

  )             src

  WE (dst.id = src_id

  WHEN MATCHED THEN UPDATE

  SET dst.column1 = src.column1

  dst.column2 = src.column2,

  dst.column3 = src.column3,

  dst.column4 = src.column4,

• Delete query to delete records from multiple tables

  All,
  
  I need a delete query that will delete the records from the tables. Please see the structure of the table & below
  

  CREATE TABLE TEMP1 (ID NUMBER(10),NAME VARCHAR2(40),CLASS VARCHAR2(40),COLLEGE VARCHAR2(40));
  CREATE TABLE TEMP2 (ID NUMBER(10),CITY VARCHAR2(40),STATE(40));
  
  INSERT INTO TEMP1 (ID, NAME,CLASS,COLLEGE) VALUES (1000,'SAM','CS','UNIV_1');
  INSERT INTO TEMP1 (ID, NAME,CLASS,COLLEGE) VALUES (2000,'RIO','CS','UNIV_1');
  INSERT INTO TEMP1 (ID, NAME,CLASS,COLLEGE) VALUES (3000,'CHRIS','CS','UNIV_1');

  INSERT INTO TEMP2 (ID, CITY,STATE) VALUES (3000,'Mount Vernon','NY');
  INSERT INTO TEMP2 (ID, CITY,STATE) VALUES (4000,'Port Jervis','NY');

  Now, I need to delete the records in these tables where the ID is '2000' by using a single delete query. Is this possible? This may be a newbie question. Help, please.

  "using a single request deletion. Is this possible?

  Nope.
  You can insert into multiple tables by using a single query, INSERT ALL job, but you cannot delete more than one table using a single query.

• Use with need to collect in bulk to insert records from multiple tables

  Hello

  I plsql record type with several tables with multiple columns. so when I used bulk collect with education for ALL. I want to insert records in multiple tables.

  Please give me suggestions.

  ForAll is designed to be used with a single DML statement, which may include dynamic SQL statements. However, I do not know what advantage this will give you your list iteration save several times, one for each table - especially since there is an air show with SQL dynamic.

  Example 1 (dynamic SQL):

  begin

    ...

    forall i in vRecList.First..vRecList.Last
    execute immediate '
    begin
      insert into Table1 (Col1, Col2, Col3) values (:1, :2, :3);
      insert into Table2 (Col1, Col2, Col3) values (:1, :2, :3);
    end;' using vRecList(i).Col1, vRecList(i).Col2, vRecList(i).Col3;
end;

  Another approach that I should work (but not tested) is using to insert all the Scriptures and based record inserts, but you need to try on your version of Oracle forall has changed between the versions.  In this case vRecList must be compatible with the Table % ROWTYPE and Table2% ROWTYPE type.

  
  

  Example 2 (insert all):

  begin

    ...

    forall i in vRecList.First..vRecList.Last

      insert all

        into Table1 values vRecList(i)
      into Table2 values vRecList(i)
    select 1 from dual;
end;

• A block in Oracle may contain data rows from multiple tables?

  Hi in my discussion with one of the DBA, a point came that is a block shouldn't have several tables lines...

  Is this true? I read in one of the OTN thread (I don't exactly remember the name of the thread) that a block can have data from several tables. If it does not, what is the table block directory mean?

  Please let know us your opinion.

  Hi all

  See the last 12 c here (http://docs.oracle.com/cd/E16655_01/server.121/e17633/logical.htm#CNCPT004). They have explicitly mentioned the term 'CLUSTER' here.

  This confusion was caused by the incorrect documentation and they corrected it

  Thanks for everyone to share their points of view.

  Just for completeness: the given system is a cluster with two nodes-CARS.

  
  

  Thus, every next run creates new child cursors:

  • I don't understand why I get child to run three sliders.
  • I don't understand why the subsequent executions do not re-use a cursor existing.

  Take a look at v$ sql_shared_cursor I see the reasons the optimizer mentions for not to reuse the sliders - but again, I don't understand

  Select child_number

  PX_MISMATCH

  USE_FEEDBACK_STATS

  TOP_LEVEL_RPI_CURSOR

  v $ sql_shared_cursor

  where sql_id = "69azwxdshhffc."

  order of child_number;

  CHILD_NUMBER P U T

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

  0 N O N

  1 O N N

  2 O N N

  3 N N Y

  4 O N N

  5 O N N

  Yet once I don't see why these reasons must be valid. If I run the query frequently enough I see strange plan renderings when I use dbms_xplan.display_cursor - as described by Timur Akhmadeev in https://timurakhmadeev.wordpress.com/2012/03/19/obsolete-cursors/.

  So the question is: someone knows something like that before? And there at - it an explanation why the server constantly reusing cursors?

  Thanks for your replies in advance.

• Insert some values into multiple tables. One of the tables has a complex primary key.

  Hello, I am using Jdeveloper version 11.1.2.3.0

  I have a FORM_TYPE table and another table Str. The table of Str is used to translate the strings from the name of the table which are read from another program from the database and used to generate forms...

  The FORM_TYPE table has a relationship with the table of STR via formtype.title_str_id = str.str_id.

  STR. table has a primary key which is based on the mf_language and str_id. columns I generated the entity for the table of STR, but impossible to insert new values of add-on application for some reason any... It is said that recording invalidates its own entity...

  I am trying to create a table that will be editable and will have the column Description, name, cdes in English, Str in French etc...

  To create a Form_Type and at the same time insert new values for each language. But can not do the inserts of the new work of STR...

• Repetitive copy of columns from multiple tables

  I need to add some "columns of audit" as created date/time line, time line last updated, etc. to a large number of tables.
  
  If I was using ERwin, I would generally create these columns in a table "scratch" in the model, with comments, appropriate data types, etc. and I could then copy (ctrl - drag / drop) to other tables as needed.
  
  Is there a way to accomplish a similar copy with SQL Developer Data Modeling? I don't want to open all the tables, go to the list of columns, click Add for each column, comment, etc.
  
  Thank you
  Mike

  Hi Mike,.

  You can do that - you can copy columns in the table editor or in the browser (in the latter case, they can belong to more than one table) and use paste functionality into the context menu table or in the table editor - you can select more than one table, use the dough. There are also two scripts of transformation to come with the tool ("Table model"), which you can customize to do less manual work.

• cannot find the table name of the multiple tables which has more columns.

  Hello
  
  I'm trying to find the NAME of the TABLE from multiple tables which has more columns. I can't count the number of columns in the table, but cannot find the name of the table that has larger columns in other tables.
  
  SELECT TABLE_NAME, COUNT (*) FROM THE USER_TAB_COLUMNS WHERE TABLE_NAME LIKE '% LOC' GROUP TABLE_NAME
  
  
  Thank you.

  in SQL, you can try this:

  var v_name varchar2(40)
  
  begin
     with
        subq1 as ( select table_name, count(*) as column_count from user_tab_columns where table_name like 'FIBER%'
                       group by table_name
                       order by count(*) desc )
     select table_name
       into :v_name
      from subq1
     where rownum = 1;
  end;
  

  To get the result:

  select :v_name from dual
  

  The clause "with" brings together all the tables and ordered them all first, by the greatest number of columns
  The final query uses the rownum restriction so that it takes the first name from the table of results of the subquery.

  The restriction of rownum also exactly guarantees a result each time so that it will work with the variable binding.

• Best approach to join several statistical tables in one

  I read different approaches to join several statistical tables in one, they all have a column 'productobjectid '.

  I want to get all the data for each product and put it in excel, then output a jpg cfchart with statistics.

  How would you do that, the part of sql?

  Thank you.

  Your "abiguous" is caused when you reference multiple tables in your SQL query that have the same field name.

  for example

  TableA a field 'ID '.

  TableB also has a field named "ID".

  If your select statement was:

  SELECT *.

  OF inner join TableA TableB on TableA.myField = TableB.myField

  WHERE ID = 4

  then SQL would be panic because he doesn't know which field ID in which table you are trying to access.  Your best bet is always prefix your domain names with the name of your table (or an alias - alias are very useful if you have long table names) when you do a Select statement.
