• Problems with the primary key of the query string

  Moving from asp to php, to work with David Power's book: The Essential Guide to Dreamweaver CS4 with CSS, AJAX, and PHP.  Recycling of my brain, so starting from scratch in the learning process.

  Everything was going perfectly until I tried to add the primary key of a record in a query string.  I compared my code with the example code for the book, and everything matches.  When previewing the page in my browser and hover over the link which must pass the main code on the next page, the query string does not appear correctly.  It shows user_id = but no figure shows, as it is supposed to.  www.webpage.com/update_user.php?user_id=

  Here is my code: (Please note, <>have been removed, as I was unable to find a way view the code in the correct way here (copy/paste was doesn't work do not, nor insert syntax))

  ? PHP {?}

  ? PHP echo $row_listUser ['family_name'];? PHP echo $row_listUser ["FirstName"];?

  ? PHP echo $row_listUser ['username'];?       ? PHP echo $row_listUser ["admin_priv"];?

  a href = "update_user.php? user_id =? php echo $row_listUser ['user_id'];?" "Edit / has

  a href = "delete_user.php? user_id =? php echo $row_listUser ['user_id'];?" ' Delete / has

  ? PHP} while ($row_listUser = mysql_fetch_assoc ($listUser));?

  Any ideas that could help me understand why this part does not in particular would be greatly appreciated.  Writing to the database worked perfectly, I see that there are numbers in the database as user_id, and it is defined as my primary key in the configuration database.  Such a simple process that is causing me headaches!

  Thank you

  You have the code to request a copy in your folder:

  $query_listUser = 'SELECT user_id, username, first_name, family_name, admin_priv from users ORDER BY family_name ASC';

  $listUser = mysql_query ($query_listUser, $connSCFDIR) or die (mysql_error ());

  $row_listUser = mysql_fetch_assoc ($listUser);

  $totalRows_listUser = mysql_num_rows ($listUser);

  $query_listUser = 'SELECT username, first_name, family_name, admin_priv from users ORDER BY family_name ASC';

  $listUser = mysql_query ($query_listUser, $connSCFDIR) or die (mysql_error ());

  $row_listUser = mysql_fetch_assoc ($listUser);

  The $listUser table will contain the results of the second query, which does not include the field user_id. delete the redundant code.

• Problem with the primary key and indexes

  Hi all
  
  I'm looking a mess on one of our main tables.
  One of the developers here added an index on 3 columns in the table, thinking that it would speed up (not noticing that it had not a PK).
  
  Subsequently another developer has noticed there do not have a primary on key. So they added a touch of primry on the single column.
  
  The problem is that now the index created on 3 columns is bein used as the primary key index. As when the primary key is created a new index was not created.
  
  Is there anyway to get rid of this index/change it correct?
  
  This table is related to many many other tables, so when we tried to remove the index we could not due to the primary key and foreign key violations with other tables.
  
  Thanks in advance

  Oracle, as you found, is quite capable to use a column enformce multi index a single column primary key, as long as the pk column is the leader in the index. This should not cause performance issues for a search of PK and if the three indexed columns are often selected only may benefit from these types of queries.

  The only way to change that now, would be to drop all CF, drop and add the PK constraint and then add all the FK constraints. A long time and potentially dangerous (if you miss to add back of the FKs) endeavour. Certainly not worth the risk in my opinion.

  I get error voilation primary key
  
  IS IT POSSIBLE TO CREATE THE KEY PRIMARY ON THE TABLE WITH ON THE DELETION OF THE DATA?
  Is IT POSSIBLE CREATING PRIMARY KEY USING 'GROUP BY' FUNCTION or OTHER FUNCTIONS?
  
  Published by: user11872870 on September 23, 2010 17:41

  Primary key columns cannot contain NULL values. If you tried to create a primary key constraint, you will get an error like this:

  ERROR at line 1:
  ORA-01449: column contains NULL values: cannot alter to NOT NULL
  

  However, you can add a unique constraint by doing something like the following:

  ALTER TABLE test ADD CONSTRAINT test_unq UNIQUE (column1, column2);
  

  I still wonder why you take the approach you take. I have a vague feeling that're missing us the key pieces of information to recommend the correct solution.

• See the primary key

  I have a form on a report and the primary key is not visible. In its place in the column is the button change. How do we guarantee that the primary key is visible as well as change the button?

  jclarke,

  There are two ways to do it. If you hold the button change then the best thing to do is to remove the 'link' information associated with the primary key column (remember / note the details for the next step) so that it displays normally.

  Then go to the page report attributes and in the menu on the right tasks, select 'add column link '. Configure it as the column ID is.

• Comparison of the data of several rows in a table - based on the primary key

  Currently I have a select statement that returns hundreds of records.  Each returned record is linked to A NUMBER of ORDER this order number has a recipe.  (a bit like a cooking recipe).  Each recipe has many records in the database related to this order number and records should be compared to records in a table that bind to a specific primary key...  (I have already developed the logic to isolate what PK I need).  If all these records that are returned by the select statement below does not match all the records containing PK in the table below, I need to get the next PK and compare all these recordings for select statements return.

  See below for a better understanding. Need a good example detailed on how to solve my problem here.

  Just to help you understand:

  Each element of the recipe is 3 parts (side, ref_des, part_number).  1 single recipe can have several parts (where the part_number), and each of these pieces should be placed on the lower side or top of the Board that is there "side" comes into play.  Same thing with Ref_Des.

  What is going on

  Select statement returns the RECIPE of ORDER NUMBER A.  There will be multiple records returned by this query.

  Select the Return statement:

  • Side
  • Ref_Des
  • Part_Number

  Example of return:

  B c17 75145-2

  T f14 89242-8

  B s12 45123-3

  etc,

  In general - what I need to do:

  There is a table called AUTO_RECIPE_DETAILS.  I take all of the records returned by the select query above and compare for each record in this table relating to the recipe 30319-000001.  30319-000001 a number of records.  It is the primary key for a whole recipe as seen above.  This primary key is bound the number of data records in this table.  The comparison is to see if all records under RECIPE_NAME 30319 -000001 match all the records returned by the select statement.

  IF IT DOES NOT MATCH: recover the following recipe in this table below 30319 -000002 and make the same comparison.
  

  Here's a perfect example of what the table looks like: (AUTO_RECIPE_DETAILS)

  
  

  RECIPE_NAME SIDE REF_DES PART_NUM

  -30319-000001 C16 87595-1 B

  -30319-000002           T B14 74150-4

  -30319-000001 T B14 34251-2          

  -30319-000001            T F24 84180-7

  -30319-000002 T B12 13710-8          

  
  

  
  

  It is the solution to my original question.  By this thread, it's the right answer and I hope this helps someone who is trying to compare two arrays element-by-element.  In the end, the advice given in this thread were correct and I will be using all of your suggestions and the scrapping of this.  Thank you everyone for your help though.

  Hello

  Assuming that your model is correct, then what you describe is a normal type of ER modeling construction known as a relationship of the CRA. It is characterized by an entity with two or more links that are mutually exclusive to each other (XOR). A typical example may be where a person entity and an entity of the Organization relate both to a bank account entity, but a bank account can only be used by a person or an organization in a mutually exclusive way. In order to serve this on a diagram, an arc is drawn between effective relationships on the side of the child, where the name of a relationship of the CRA.

  Google will be of multiple examples and explanations.

  In a perspective of physical databases, this can be implemented in general in two different ways.

  1. assuming that all parents in the relationship of the CRA have identical PK, that is to say, a number that is generated, the child may have a FK of the same type and an entity of type column that defines what entity the FK is. The advantage of this is that it is a bit more compact and is expandable without schema changes if you want to add more relationships. The downside of this is that the CF cannot be defined at the database level and will build on the code to be executed or both in the application and the database as a trigger.

  2. regardless of types PK for parent entities, the child has a separate optional FK appropriate for each relationship in the arc. Each FK is defined at the database level while maintaining the exclusivity of relationships, a constraint is defined on the table that prevents several FK being filled for a given instance. This can be a little messier that there must be a (column/s) FK for each relationship in the arc, but the relationship may be limited to the level of the object database with the help of FK constraints and a check constraint. This could also be considered to be more technically correct implementation.

  Hope this helps

• exp/imp with sequential primary key table.

  Hello
  
  I have a general question about EXP/IMP a table with primary key sequence. I need exp rows in this table of 11g DB and their imp to 9i DB. This table is the same on 11g and 9i. Table 11g is updated daily. I want to import lines which are the only new records to 9i to expedite the process. As this main table of the key is sequential, I intend to export with where table_key > N, N is the max of last importing table_key and then proceed to import on this dump file. Don't you see any problem doing it this way?
  Your expertise is greatly appreciated!

  Hello

  I have no problem at all.
  If you do not forget to use the 9i export tool, then you should be OK
  Also a full table export and import with ignore = Yes will ignore the records that violate the primary key and import only new records.
  However, it is not a very clean way to do it.

  Success!

• dynamically find the primary key of a table

  Hello
  
  How can I see (dynamically) participating in a primary key table columns?
  
  Let's imagine that we have a procedure receives the name of the table as a parameter:

  PROCEDURE delete_record (table_name IN VARCHAR2)

  The procedure is to delete a record in the table 'table_name '.

  -- g_record is a global variable containing the values of the record that should be deleted.
  l_sql_statement := 'DELETE FROM ' || table_name || ' WHERE ' || primarykey_col_1 || '=' || g_record.col_1;
  
  EXECUTE IMMEDIATE l_sql_statement;

  So, how do I see the columns that make up the primary key, perhaps, somehow the using the description of the table?
  
  Thank you!

  You can use the ALL_CONSTRAINTS in combination with views ALL_CONS_COLUMNS to retrieve this information (there are also views DBA_ and USER_ as well). Here is a sample of SQL that you could use:

  SELECT  COLUMN_NAME
  FROM    ALL_CONSTRAINTS         AC
  JOIN    ALL_CONS_COLUMNS        ACC     ON ACC.TABLE_NAME       = AC.TABLE_NAME
                                         AND ACC.CONSTRAINT_NAME  = ACC.CONSTRAINT_NAME
  WHERE   CONSTRAINT_TYPE = 'P'
  AND     ACC.TABLE_NAME  = table_name
  

  I wonder however this method because it seems unorthodox. Could you provide a reason for this kind of implementation?
