• The most effective way to insert form data into multiple tables and w/autonum

  Hi all, this is my first post here. I am new to APEX and PL/SQL. I have ColdFusion and SQL, and I'm used to perform CRUD operations in my CF Tags application files. From what I've read so far, so if this is accurate, it seems that it is more efficient to perform most of the CRUD operations on the database side, I hope that for advice on the best way to accomplish what I ask - even if I'm trying to do is better off in my new APEX application I am open to this information as well.
  
  I have a form whose data must reside in two tables. Table A is a one-to-one relationship table and stores General information for each request. Table B is a table of one-to-many observations and should store unique records for each type of comment entered on the form, of which there are 3 comment fields on the form, I'd end up with 3 disks in table B for 1 in table A. I am generating an AutoNumber for table A with a sequence and relaxation. I want to do is take the AutoNumber I just created and use it for insertion in the Table B each insertion I have to do. This is where I am stuck.
  
  I would like to comment on 1) where I should put all these operations and 2) how best to go about what I want to do coding. In ColdFusion, it is as simple as inserting the record in Table A, immediately asking to table A more recent recording and storing (auto) ID in a variable and then using this var for any other table insertions, I had to do. I know it must be at least a little easier in the Oracle world, I just need a nudge in the right direction. Thank you!

  OraclePledge,

  You're pretty close to not having worked with oracle a lot.

  This section is backwards:

  insert into sch.tbl_main(cust_lname,cust_fname,acct_num)
  values(:P3_CUST_LNAME,:P3_CUST_FNAME,:P3_ACCT_NUM);
  
  select "SCH"."TBL_MAIN_SEQ".currval
        into
        v_ID
        from dual;
  

  Even if it will work if you only have a single user, it's a potential bug with two or more users. First select the key (if it's first use nextval rather than currval) can use it in the insert statement.

  See you soon,.

• Comment of tables and columns are included in the Data Modeler

  Hi all
  I used Oracle SQL Developer Data Modeler (Version 3.0.0.665) and created a data model for my project. I sent an email a PDF version of the data model to our systems analyst. She asked if I could re - create the data model and include table and column comments. Is this possible and if so how this work is it?
  
  Thank you for your comments,
  
  Seyed

  Seyed salvation,

  I used the Data Modeler and create a report. The report included 36 .csv files

  What is the purpose of this 'report' task, because 36 files csv does not sound like report to me. Watch "files > reports" feature - you can generate reports for your model. -for any model, single table or tables belonging to specific subview. The report of the complete table contains additional details, so if you need these comments, then only you can create a template and select column comments appear only. So some general information table will be also included.

• Select the data in a table and update in another table

  Dear experts,

  create the table TB_ENCRYPT

  (

  Identification number,

  Varchar2 (200) KEY

  );

  INSERT INTO TB_ENCRYPT VALUES(1,'HJUVHDUIFBSDGVU');

  SELECT * FROM TB_ENCRYPT;

  1 HJUVHDUIFBSDGVU

  create TABLE users)

  username, NUMBER of

  password VARCHAR2 (200)

  );

  Insert users

  values (1, 123 # "")

  Insert users

  values (2, 456 #')

  Select * from users;

  1 123 #.

  # 2 456

  I want to select the data KEY for table TB_ENCRYPT column and update in the column of tables for the respective key user password

  TB_ENCRYPT table contains only a single key value. Comparing this key, I want to update the old value of the key to the new value.

  For encryption and decryption I followed the java class method.no is worried about that.

  create or replace

  PACKAGE PCK_ENC AUTHID CURRENT_USER AS

  FUNCTION DECRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.decrypt (java.lang.String, java.lang.String) return java.lang.String ';

  FUNCTION ENCRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.encrypt (java.lang.String, java.lang.String) return java.lang.String ';

  END;

  SELECT PCK_ENC. ENCRYPT('1234','HJUVHDUIFBSDGVU') FROM DUAL;

  HERE,

  1234 - is the password of the users table column data

  HJUVHDUIFBSDGVU - represents the key of table TB_ENCRYPT column data.

  Comparing this key, I want to update the old value of the key to the new value.

  I tried with this method

  declare

  cursor c1 is

  Select the key

  of TB_ENCRYPT

  where id = 1

  update the id;

  Start

  for c1_rec looping c1

  update users

  password is PCK_ENC. Encrypt (Password, Key)

  the location being c1;

  commit;

  end loop;

  end;

  /

  Help, please

  You can use the MERGE statement.

  merge into users
  using tb_encrypt
     on (id = userid)
    when matched then
        update set password = PCK_ENC.ENCRYPT(password,key);
  

  And why you encrypt your password. This isn't a good idea. Just password hash.

• Size of the data in a table and the size of the table

  I am trying to determine the size of the data in a table and also the overall table size. I use the following query:
  
  SELECT BOTTOM (a.owner) as owner,
  LOWER (a.table_name) AS table_name,
  a.tablespace_name,
  a.Num_Rows,
  ROUND ((a.blocks * 8 / 1024)) AS size_mb,
  a.Blocks,
  a.Blocks * 8 Blocks_Kilo_Byte.
  a.PCT_FREE,
  a.compression,
  a.Logging,
  b.bytes / 1024 / 1024
  From all_tables a, dba_segments b
  WHERE the a.owner AS SUPERIOR ("USER_TEST")
  AND a.table_name = "X_TEST_TABLE."
  AND b.segment_name = a.table_name
  AND b.owner = a.owner
  ORDER BY 1, 2;
  
  Is this the right way to go about finding the size of the data in a table? If this isn't the case, please give your suggestions.
  
  BTW, this in a 10g version.

  You probably want to use the DBMS_SPACE package. In particular, the procedures SPACE_USAGE and UNUSED_SPACE to get an accurate account of the use of space in a table. Your application may give you a relatively accurate estimate if the optimizer on your table's statistics are reasonably accurate estimates. But there is no guarantee that the optimizer statistics are accurate.

  If you want just an approximate answer and you're comfortable that your statistics are accurate, this query may be close enough. If you want a specific response, however, use the DBMS_SPACE package.

• Find the key referenced foreign Table and column

  Can someone please refresh my memory?
  
  How can I determine which table and column refers to a foreign key?
  
  For example, with select * from ALL_constraints WHERE TABLE_NAME = 'my_table '; I can see forced CONSTRAINTA_FK and CONSTRAINTB_FK I guess reference another table and column because CONSTRAINT_TYPE = "R", but it isn't that I get. "
  
  I would get all the way to the referenced table and the column I just don't remember how.

• Write multiple rows and columns of the worksheet

  Is it possible to write several rows and columns of the spreadsheet, with the ability to add data to the file and create a new file if it does not exist?
  I tried to write to table vi, but I couldn't make it work.
  It won't let me write several lines in the same column.
  Can someone please give me an example?
  Thanks in advance.

  If you want to use the tab character (\t) as the delimiter, then check the txt file.  Then Excel will open as you wish.

  If you want to keep the csv extension, then use comma (,) as a separator.

• Rename tables and columns in sql running that accessing these columns in the table.

  Hello

  Using oracle 11.2.0.3

  We want to rename columns, tables and work just a sql scripts for this.

  If sqls who have access to those running long tables/columns for example reports what is happening

  Existing sql running, will work perfectly in that picked up sql before table/colum rename or will they crash if tables/columns renamed during them.

  scripts wil take a few seconds to run maximum

  Thank you

  The only other activity that would go on select is against these tables/columns. No etl isnert/update/delete etc wil, which happened during the name change.

  Only possible activities are report instructions srunning select.

  Tried to run a long selection and rename that select while that was going on and got no error on the test system.

  This is because certain statements does not place locks on tables or lines, so even if a session is reading data, another session can make some ddl (or dml) manipulation.

  In this situation (with only selects, no other dml queries), renaming can be done, but the question remains, what the application code?

  If it refers to old column names after name change operation, is no good.

• Create the form for selecting data in multiple tables

  Hello

  I'm getting APEX for the first time and I just read 2 days dev Application Express guide

  I tried to play and I can't create a report with the form that select data from several tables

  What I want to achieve is a report we'll say 'USERS' makes MANAGER_ID ID, NAME, with a form that allows me to create, delete, change users

  The problem is that, once the report with the form created, if I click on create (to create a user) it will ask me for id, name, and manager_id

  I need a water drop down which allows me to select managers in the table manager instead of manually insert Director id

  How do I do that?

  Thank you!

• Select Max (date) between multiple tables

  I need to retrieve a record from a Table in a set of similar tables with a common "date field". You can select the record where this "date field" value is greater between multiple tables.

  Here, any help is appreciated.  Thank you in advance.

  FOR EXAMPLE

  No. EMP is the primary key.

  Again, each table can have multiple records for EMP n ° 1

  TABLE1:

  FIRST NAME

  FAMILY NAME
  THE EMP NO.

  BASE SALARY

  DATE_FROM

  TABLE 2

  FIRST NAME

  FAMILY NAME
  THE EMP NO.

  SALARY GRADE

  DATE_FROM

  TABLE 3

  FIRST NAME

  FAMILY NAME
  THE EMP NO.

  COMPENSATION

  DATE_FROM

  Hello

  Said Knani, if you use the current design of the table, then here is a way to do what you want:

  WITH union_data AS

  (

  SELECT MAX (base_salary) AS sal FROM table1 UNION ALL

  SELECT MAX (grade_salary) table2 UNION ALL

  SELECT MAX (compensation) FROM table3

  )

  SELECT MAX (sal) AS max_sal

  Of union_data

• Alias table and column aliases

  I'm new to the discoverer. I have some confusion.

  
  

  1. If it is possible use different aliases for the same table during the creation of spreadsheet?

  Need to produce different joins.
  

  for example:

  SELECT C1. Name, C2. Remarks

  CLIENTS C1,.

  C2 customers,

  Ticket T,

  Sale S

  WHERE C1. Client_Id = T.Client_Id AND C2. Client_Id = S.Client_Id

  2. How can I use the Alias column to show as a custom in the worksheet column heading?

  for example:

  SELECT Client_Default_Name AS name OF customers
  

  
  

  Thanks in advance.

  Hello

  first question:

  the sql worksheet is always structured according to the EUL (the end user layer). If you have used two customer tables and created a join of tables then the sql is generated according to your requirement. There is no way we can have discoverer create a sql like this. If you are interested with the sql. You can create a custom in the business district folder and paste the sql code and create a report on the top of the custom folder.

  second question:

  You can always change the topic in the discoverer more filing cabinets according to your requriement

  hope this helps

• to ensure the integrity of data in multiple tables materialized

  Hello
  
  
  
  I have a problem and I am not able to solve. Partly, it's because of my poor knowledge of SQL. I have three tables and I use a sequence to enter data into them.
  
  I am attached to is to create a materialized view (full or quick, depending on) with discount to the validate option to verify that each table contains unique data to each other.
  
  
  
  I write code so you can get there:
  
  
  

  CREATE TABLE table_1 (
  ID NUMBER PRIMARY KEY
  
  );
  
  
  
  CREATE TABLE table_2 (
  ID NUMBER PRIMARY KEY
  
  );
  
  
  
  CREATE TABLE table_3 (
  ID NUMBER PRIMARY KEY
  
  );
  
  
  
  INSERT INTO table_1 VALUES (1);
  
  INSERT INTO table_1 VALUES (2);
  
  INSERT INTO table_2 VALUES (3);
  
  INSERT INTO table_2 VALUES (4);
  
  INSERT INTO table_3 VALUES (5);
  
  INSERT INTO table_3 VALUES (6);

  I want to write create a materialized view that will give me the output only in the case that it has same values in two different tables. I had to date.
  
  
  

   
  
  
  CREATE MATERIALIZED view mv_test 
  REFRESH COMPLETE ON COMMIT
  AS
  SELECT count(1) ROW_COUNT
  FROM dual 
  WHERE EXISTS (
       SELECT a.id 
       FROM table_1 a
       WHERE a.id IN(
           SELECT b.id 
           FROM table_2 b)) 
  OR EXISTS (
      SELECT a.id 
       FROM table_1 a
       WHERE a.id IN
               (SELECT c.id 
               FROM table_3 c))
  OR EXISTS (
      SELECT b.id 
           FROM table_2 b
      WHERE b.id IN
               (SELECT c.id 
               FROM table_3 c)); 
               
      ALTER MATERIALIZED VIEW mv_test
      ADD CONSTRAINT cs_mv_test
      CHECK (row_count = 0) DEFERRABLE;

  This sql statement itself returns no line if my logic is correct. And in case there was a few lines in two different tables, it would return 1 and constraint would throw an error.
  
  
  
  However, I can't create this with ON COMMIT option. When I try to compile I get:
  
  
  

   
  
  
  
  ORA-12054: cannot set the ON COMMIT refresh attribute for the materialized view

  I went through the documentation, I tried mat_view creation logs etc.
  
  I know that one of the mistakes is that I am referencing the double table and I don't know if I can use EXISTS.
  
  
  
  Unfortunately, my SQL wisdom ends here. I need help to rewrite the sql code, so it would be a materialized view with Refresh on the validate option. Help, please!
  
  
  
  I know that since I'm on a sequence there is little chance that same value will enter into two different tables, but I would like to make somekind of audit.
  
  
  
  
  
  Thank you in advance.

  >

  I know that since I'm on a sequence there is little chance that same value will enter into two different tables, but I would like to make somekind of audit.

  If you are certain that you control all the entries in the table and you are probably using a sequence to be inserted in the three tables then there is physically no possible in all tables, you will get duplicate values.

  Write something to check if it is the case would be nearly identical to writing something to verify that 1 + 1 is really equal to 2 in 100% of cases.

  If you need to, however. consider something similar to what can be better that follows:

  select *
    from table_1 t1
    full outer join table_2 t2 on (t1.id = t2.id)
    full outer join table_3 t3 on (t1.id = t2.id
                                   or
                                   t2.id = t3.id)
   where t1.id+t2.id+t3.id not in (t1.id,t2.id,t3.id);
  

• Flexible, set up including the tables and columns of text?

  I need to set up tables (annual report) and some text between the two notes.

  I would like to have frames as little as possible on every page - for InCopy workflow later.

  If I paste the text of the regular column in the frames containing the tables anchored that I must apply the shift of different basis for each block of anchor text, text which is not a nice workflow.

  Can you recommend a skillful means and flexible to set this place that will make the tables and text boxes flows if more lines or more text are added?

  Best regards

  Nina storm

  For this test I did it manually, but I have no reason to think that it would behave differently as part of a style. As far as I know, ID will attempt to balance the two columns automatically. If there is not enough text to divide into two columns it will not appear to divide but always see you any extra spacing and add just enough text to be wider than the column width of Courland and your line will have a gap in it for the gutter of the column.

  OK, I've just defined a style with the attribute of split, and Yes, it works in the same way. If you have a single paragraph, the paragraph is divided. If you have more than one, the block is divided, reading down by the first paragraph to the second (assuming that the linecounts work that way) in the first column before splitting into the second column. Paragraphs distributed individually. ID is to balance my columns automatically and will adjust the break if I edit, and if the number of rows is not divisible by 2 short column is on the right.

  What is I have several tables of several users and object_schema in handler_schema.
  
  I hope I'm able to clear my question, doubts please let me know.
  
  Best regards, Imran

  Hello

  object_schema - the schema of the object to be audited. (If the value is NULL, the schema of the current user is supposed).
  in case if you want to audit for multiple users - then make a test taking a value null and test access important tables - where relevant audit records are generated according to your requirement or not. I have not tested... try it
