• 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,

• Explicit cursor, column from several tables in a variable

  Here's the situation. This DB has tables of metadata. An example of table name would be g3e_attribute. Once you insert a record in a metadata table a trigger of executions insert and insert records in the g3e_attribute_0009 table (table of language, this is what I call it). It would insert in g3e_attribute_000C is the default language is the French. There is also a delete trigger so that if you delete a record in a table of metadata it deletes the corresponding language table. Well, somehow we have entered the language tables that are not in the metadata table. A problem with the system.
  
  There are 139 tables of language so I prefer not to do it manually.
  
  
  So I'm keen to make this code
  
  delete < table language > where < primary > not in (select < primary > in < metadata table >).
  
  So I need to loop through the table and and the corresponding primary keys.
  
  I have this code to get the table names
  Select table_name, substr (table_name, 0, (length (table_name)-5)) in all_tables where table_name like 'G3E_ % _000% ';
  
  This will display both the language metadata tale table names and.
  The table of language with either _0009 or _000C as a suffix, I take everything but the last 5 characters to get the table metadata.
  
  And I have the code to find the primary key of the table.
  SELECT column_name FROM ALL_CONS_COLUMNS A JOIN ALL_CONSTRAINTS C ON A.CONSTRAINT_NAME = C.CONSTRAINT_NAME WHERE 'G3E_LEGENDENTRY' AND C.CONSTRAINT_TYPE = C.TABLE_NAME = 'P ';
  
  
  So I just need to loop through all the tables. Put these pieces together, that's where I encountered a problem. I started to do a procedure, but I ran into a problem.
  
  When you loop, you move the record being the explicit cursor in a variable. Well, you can set the variable as a vertain column type (%), or type (%ROWTYPE) of the line. Although the sql I use to create the cursor takes columns from multiple tables and returns three columns. So I'm not sure how ot define the variable. The only work around I found was to make a table column_name that contains the table table,. Define the variable as rowType.
  
  Is there an easier way to do this?
  
  
  Thank you

  A couple of points.

  You should not really mix ansi joins and joins in the place where clause. Choose a style and stick to it.

  You can't do the DDL directly in pl/sql. You need to do this, use dynamic sql. something like:

  create or replace
  PROCEDURE SYNC_LANGMETATABLES AS
  
  CURSOR c_TABLE_PRIMARY IS
     select D.table_name, substr(D.table_name,0,(length(D.table_name)-5)),
            column_name
     from all_tables D,
        JOIN ALL_CONSTRAINTS C
           on C.TABLE_NAME = D.TABLE_NAME
        join ALL_CONS_COLUMNS A
           ON A.CONSTRAINT_NAME = C.CONSTRAINT_NAME
     where D.table_name like 'G3E_%_000%' AND
           C.CONSTRAINT_TYPE = 'P';
  
     v_LANGTABLE ALL_TABLES.TABLE_NAME%TYPE;
     v_METATABLE ALL_TABLES.TABLE_NAME%TYPE;
     v_PRIMKEY ALL_CONS_COLUMNS.COLUMN_NAME%TYPE;
  
  BEGIN
     OPEN c_TABLE_PRIMARY;
     LOOP
        FETCH c_TABLE_PRIMARY INTO v_LANGTABLE,v_METATABLE,v_PRIMKEY;
        EXIT WHEN c_TABLE_PRIMARY%NOTFOUND;
        execute immediate 'delete from '||v_langtable||' where '||v_PRIMKEY||
                          ' NOT IN(SELECT '||v_PRIMKEY||' FROM v_METATABLE)';
     END LOOP;
     CLOSE C_TABLE_PRIMARY;
  END;

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...

• 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;

• Get columns from the table shown in the iterator

  Hello...

  I have the table in a collection of standard panel.  So, I can show/hide certain columns in the table using the columns in the view menu.

  Then I'm trying to do is export to excel (using apache poi) by looping through the table iterator.  What I can't do is search if the column is not displayed.  I don't want all the columns that are exported without worrying.  How can I achieve this?

  My bean is similar to the following for loop through the iterator:

  BindingContext bindingContext = BindingContext.getCurrent ();

  BindingContainer bindingContainer = bindingContext.getCurrentBindingsEntry ();

  DCIteratorBinding dcIteratorBinding = (DCIteratorBinding) bindingContainer.get ("EmployeesIterator");

  lines [] oracle.jbo.Row = dcIteratorBinding.getAllRowsInRange ();

  for (oracle.jbo.Row line: lines) {}

  {for (String colName: {row.getAttributeNames ())}

  output to excel cell here using row.getAttribute (colName) m:System.NET.SocketAddress.ToString)

  }

  }

  Thank you.

  Hello

  It's like ask the engine in your car to what colors the seats have. The iterator doesn't know anything about the visible state of a column. If the displayed columns must be determined from the table instance (richeTableau)

  The following article solves exactly the requirement that you have: Oracle ADF: Build Your Own it comes with a sample that you can download here: http://www.oracle.com/technetwork/issue-archive/2013/13-jul/o43adf-1940728.zip

  Have a look at CustomPanelCollectionBean.java:

  The method and code that you want to look for is:

  private String getRowHtml (row rw) {}

  StringBuffer rowHtmlBuf = new StringBuffer();

  Read visible columns in the table of the table instance. This way the

  PanelCollection can be used to show/hide columns and exclude

  printing to HTML

  Table richeTableau = this.getRichTable ();

  the list of columns determine the print attributes

  The list of columns in = table.getChildren ();

  int attrCount = columns.size ();

  rowHtmlBuf.append (this.addRowStart ());

  for (int i = 0; i)< attrcount;="" i++)="">

  for all visible columns, add columns to print

  If (((RichColumn) columns.get (i)) .isVisible ()) {}

  If (rw.getAttribute (i) instanceof ViewRowSetImpl) {}

  ignore the collections of detail used for master/detail example

  constraints in British Colombia ADF

  } ElseIf (rw.getAttribute (i) instanceof oracle.jbo.domain.Timestamp) {}

  shorten date to exclude the infromation times

  SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");

  String dateFormatString = sdf.format (((Timestamp) rw.getAttribute (i)) .getData ());

  rowHtmlBuf.append (this.addDataCell (dateFormatString));

  } else {}

  Prnt attribute values and if sure that null values don't raise a NPE. Add a white character to NULL

  attribute values

  rowHtmlBuf.append (this.addDataCell (rw.getAttribute (i)! = null? rw.getAttribute (i) m:System.NET.SocketAddress.ToString ():))

  " "));

  }

  }

  }

  rowHtmlBuf.append (this.addRowEnd ());

  Return rowHtmlBuf.toString ();

  }

  You need to access the Rich Table instance (for example using the JSF component binding) to then compare the attribute in the iterator with the visibility of the column

• 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

  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.

• Correspondence of the columns from one table to another

  I have a database column that contains the name of a person. I have another table that has a column that contains the names separated by a comma.

  I want to match records where all records of two columns have a corresponding name. I tried this:

  < cfquery name = "MyQuery" datasource = "myds" >

  SELECT *.

  OF TBL_A

  WHERE TBL_A.customername IN (#DifferentQuery.ListOfNames #)

  < / cfquery >

  Everything that I try results in only get a recording. Basically, I want to get all records from a table where one of its columns contains the name of a column in another table.

  It's a many-to-many relationship. That is to say an editorial can be linked to many ads, and vice versa.  He is best represented with three tables. Such as:

  Table: [Editorial] column: [EditorialID (PK), EditorialText,...]

  Table: Columns of the [advertiser]: [AdvertiserID (PK), AdvertiserName]

  Table:   [Editorial_Advertisers] columns: [EditorialID, AdvertiserID]

  The name of the advertiser throw himself into a column...

  my client can decide which ads get related to which editorials

  The third table stores the relationship between ads and editorials.  So instead of storing a list of advertisers, you need to insert record for each EditorialID + AdvertiserID combination. You can then use joins to retrieve all the advertisements for EditorialID 123.

  SELECT  a.AdvertiserName
  FROM     Editorial_Advertiser ea INNER JOIN Advertiser a ON ea.AdvertiserID = a.AdvertiserID
  WHERE   ea.EditorialID = 123
  

• Storage from multiple tables in one MySQL query

  So I would like, with a single MySQL query, extract data from a table (say 15 rows of data) and then extract data from another table (lets say another 15 ranks) and who joined the first, so that I can view and paginate a single list (of 30 rows now).  I don't think that a join is what I'm looking for, because I want the second list should be annexed to the first and not mixed in.  I would just use different queries, but I already have the paging function implemented for a single set of records, and implementation with two (where the second begins when the first leaves) seems daunting. However, if you have any tips on one, they would really help.

  Thank you

  You need to use a UNION to join the two select statements. The number of columns and the data types of each selection must match.

• How to remove columns from the table on the master 1-0?

  I have an array of 96 columns with strings. I also have the array of int 96-elemets (mask) with 1 and 0.

  What I want to do is to is to remove (or hide - but I read that it is not possible) all the columns with index corresponding to 0 in the mask table.

  example:

  columns in the table

  1 2 3 4 5

  mask

  0 1 0 0 1

  I want to remove the columns 1, 3 and 4 and leave only 2 and 5 in my table.

  How can I do?

  If I create loop for with i as the index of the column, when I do DeleteTableColumns() columns number decreases, and I get an error of range out of

  Or do I have an option to hide the unnecessary columns (not set their width to 1, it's very ugly-looking)?

  Please help me (())

  Hello rovnyart!

  1. removal of columns in the table:

  I suspect that the reason why you get the out-of-range error is due to fact that in your loop, you delete the columns in the table, you'll eventually end up by referring to a column that no longer exists, because the other columns before it have been deleted. While you remove each column of your table in the loop for example, the column index number will move, because you deleted the other columns in front of her.

  To resolve this, even if you delete a column in your loop, make sure that you take also into account that the index of the column is moved because of the removed columns.

  2 hide columns in table:

  You can use the ATTR_COLUMN_VISIBLE attribute to hide columns in the table:

  3 alternatives:

  Note that another alternative would also use a tree instead, control as the tree control also supports the hidable columns:
