• Customized for a Unique constraint processing scripts

  Hallo,

  How can I create the Unique constraint (not a Unique Index) transformation scripts:

  Hello Oleg,

  lines 14 and 15 are false. The use of the persistence method is:

  uniq.setIndexState ("Unique constraint");

  Other options here - you can spot if you look at the XML file representing the table with PK and UK constraints and regular index - "primary constraint, «Unique Index ordinary', «Clear index»»

• How can I create a constraint on the combination of four columns...

  Dear Guru,

  I have a question... I created the table with columns like "CCode', 'Size1', 'Size2', 'Sch1', 'Sch2', 'Description', 'CCdate '.

  Here I wanted to create a unique constraint on the combination of four columns "CCode', 'Size1', 'Size2', 'Sch1', 'Sch2.

  My requirement is that I don't want to allow duplicate records in the table for the four columns only.

  for example: "CC123", 10, 25, S110, S250,.

  If the new record comes with the same data. Then, I do not want to insert this record.i want to get a constraint voilated error.

  How can I create a constraint on the combination of four columns...

  Pls help me on this issue...

  Kind regards

  Shitab...

  I suggested already here the syntax,

  ALTER table your_table

  Add constraint cons_name unique (col1, col2, col3, col4, col5);

  And don't call me 'Sir '.

• Unique constraint on the values in both directions

  I'm looking to create a unique constraint that works in two ways. Say I got a constraint unique in columns 1 and 2. I want it to be impossible for the two lines below the two exist at the same time. Is there a way to do this? I googled around for a while now and I found nothing that works so far.

  Header 1	Header 2
  Dog	CAT
  CAT	Dog

  Hello

  You can create an index based on a single function:, like this:

  CREATE UNIQUE INDEX table_x_header_1_header_2

  ON table_x (LESS (header_1, header_2)

  More LARGE (header_1, header_2)

  );

  How will you use these values?  You might be better to simply create a regular old unique constraint, but also have a CHECK constraint to ensure that header_1<= header_2. ="" that="" way,="" when="" you="" want="" to="" search="" for="" the="" combination="" ('cat',="" 'dog')="" you="" won't="" have="" to="" search="" for="" ('dog',="" 'cat')="">

• Index naming standards does not and unique constraints

  I found yet another question of naming standards

  I have tried to create a unique constraint as a normal index via the unique constraints and indexes in Properties of Table with the assumption that it will use the design properties of models.  This isn't.

  

  As noted in the image of the model above, my Unique constraint model is {table} _ {columns} lancement_remarques

  and my model of Index idx _ {columns} {table}.  Yet, when I try to create the Unique constraint, it creates the naming convention in names like CUSTOMER_ADDRESS__UK (2 lines of underscore?) as shown below.

  

  My assumption is that he needed a column, so I added the column and also applied the rules naming - nothing.

  

  Is my wrong assumption on these constraints being appointed through the models?  If this is not the case, what naming rules is in this context?

  The same behavior is evident when you try to create index.

  I get not all comments on my posts.  Are these bugs or just user error?

  Hello

  Thank you to report the problem, I logged a bug. You can get 'Rules of naming' works properly if you press the button 'Apply' before that.

  I get not all comments on my posts.

  I don't think that anyone (or any job) has been ignored on this forum. Depending on the complexity of the problem and our current commitment (other urgent tasks, holidays, time zone), you can get answer almost immediately or after a certain time.

• is there a way that we could create a unique link that someone can click on an email to bring them to a cart to fill their quote?

  is there a way that we could create a unique link that someone can click on an email to bring them to a cart to fill their quote?

  Hello

  Here is how the configuration would work - http://client2.worldsecuresystems.com/get-quote/java-in-a-nutshell - you can add some nice CSS to ensure that the screen does not Flash or anything like that. Here's how it was built:

  1. create a new model, paste this piece of code inside:

  {tag_pagecontent}
  

  2 create a new catalog, all the products of this catalogue will redirect users directly to the GET a quote form. Assign the model created in step 1

  3 change the presentation of the latge product and place the button buy now in a hidden div:

   
  {tag_buynow}
  

  4. change the shopping basket page layout and make sure the GET a quote button is present:

  {tag_getquotebutton}
  

  5. place this code at the end. You need to replace 606879 with the ID of the catalog created in step 2

  {% if globals.get.CatalogueID == 606879 %}
  
  {% endif %}
  

  What will happen, it is like this:

  1. whenever someone opens a product using the link to the custom catalog buy it button will now be clicked
  2. the site visitor is then redirected to shopping cart layout where the other script checks the catalog, the visitors came. If this is a "known" catalog redirect another arrives and load the GET a quote layout

  Make sure that you have loaded in your models of jQuery and liquid activated on your site.

  One more thing, you need to monitor is you will need hide this catalog custom catalog your site listing.

  Hope this helps,

• Why we cannot create more than one primary key on a table. Why we create several unique key on a table. Please explain if anyone have details of this.

  Why we cannot create more than one primary key on a table. Why we create several unique key on a table. Please explain if anyone have details of this.

  «a primary key has semantic meaning, it is to be immutable (never change of value), unique and not null.»

  a unique constraint is simply "at any time, these values are unique - they can change and they can be null.

  You use a unique when constraint

  (a) you do not already have a primary key for a table can have only one
  (b) you allow NULL values in attributes
  "(c) to allow you to update the values in the attributes.

• Adding a UNIQUE CONSTRAINT to an existing column with duplicate values

  Oracle Forums Hello, I have a table that contains rows 11 901. I tried to define the UNIQUE constraint on the column of xcode, but encountered an error: the column already contain duplicates! I rescued following SQL 'SELECT COUNT (*) FROM States;' the result is 11 901 and 'SELECT COUNT (DISTINCT (xcode)) FROM States;' the result is 11 680. So to enforce this unique key I have to remove the 221 lines. Please how can I do this?

  REMOVE duplicates...

  For example, as

  delete from your_table t
  where rowid <
     (
     select max(rowid)
     from your_table r
     where t.unique_column = r.unique_column);
  

  Thne create the constraint.

• Question of design on unique constraints while moving to multi-tenant

  Hi all
  
  Please see the definition of this simple table:

  CREATE TABLE emp 
      ( 
       id INTEGER  NOT NULL , 
       name VARCHAR2 (30 CHAR)  NOT NULL , 
       birthdate DATE  NOT NULL , 
       username VARCHAR2 (10 CHAR) ,
       CONSTRAINT PK_ PRIMARY KEY ( id ) ,
       CONSTRAINT UC_emp_username UNIQUE ( username )
      );

  In this framework, each user can (not essential, authorized NULL) have a user name. A user name can only be used once. An application that uses this type of table is not multi-tenant capable.
  
  Now if I run the application of several tenants, I add a column tenant_id like this:

  CREATE TABLE emp 
      ( 
       id INTEGER  NOT NULL , 
       name VARCHAR2 (30 CHAR)  NOT NULL , 
       birthdate DATE  NOT NULL , 
       username VARCHAR2 (10 CHAR) ,
       tenant_id INTEGER  NOT NULL ,
       CONSTRAINT PK_ PRIMARY KEY ( id ) ,
       CONSTRAINT UC_emp_tenant_username UNIQUE ( tenant_id, username )
      );

  I have archived almost my goal:
  However, a user can (not essential, authorized NULL) have a user name. A user name cannot be used once BY the TENANT (see changed CPU). Of course, each tenant must be provided with an account named 'administrator', so the CPU must include the tenant_id. But what does not work:
  
  As soon as I add a 2nd employee for a tenant and this user doesn't have a login name (and therefore no user name), the UC has banned the addition of this user.
  It was no problem in the 1st case, because the CPU included a single column and a row in the base table with a NULL value in this column is simply ignored in the index.
  In the 2nd case, each row in the base table is included in the CPU, because the tenant_id column is NOT NULL. If the combination {tenant_id:1, username: NULL} cannot exist only once. This means that almost all employees must have a user name.
  
  What is the solution here?
  Drop the CPU is not a solution.
  Is it really necessary to move the user name column to a new table, as in the following? It just doesn't feel good to introduce a table of relationship for a 1:1 relationship.

  CREATE TABLE emp 
      ( 
       id INTEGER  NOT NULL , 
       name VARCHAR2 (30 CHAR)  NOT NULL , 
       birthdate DATE  NOT NULL , 
       tenant_id INTEGER  NOT NULL ,
       CONSTRAINT PK_emp PRIMARY KEY ( id )
      ) ;
  
  CREATE TABLE username 
      ( 
       id INTEGER  NOT NULL , 
       emp_id INTEGER  NOT NULL , 
       username VARCHAR2 (30 CHAR)  NOT NULL , 
       tenant_id INTEGER  NOT NULL ,
       CONSTRAINT PK_username PRIMARY KEY ( id ) ,
       CONSTRAINT UC_username_emp UNIQUE ( emp_id ) ,
       CONSTRAINT UC_username_username_tenant UNIQUE ( username , tenant_id ) ,
       CONSTRAINT FK_username_emp FOREIGN KEY ( emp_id ) REFERENCES emp ( id ) 
      ) 
  ;

  Any ideas or links to books that are greatly appreciated.
  
  Thank you

  Hi, Lawrence.

  Sorry, I'm not sure you understand the problem. It would be useful that you posted some INSERT statements that should be allowed, and some that must fail because they violate the rule of oneness. Or by post at least a scneario of business that you might neeed to model. For example "tenant 1 has 3 employees: 11, 12 and 13." Employee 11A username "FFL". 12 has no username. 13 should be able to choose any username except "Elf", or not having a (just like the 12). 2 a 2 employees... »

  You can create an index based on a single function. For example, if the user name is optional:

  CREATE UNIQUE INDEX emp_name_unique ON
  username ( NVL2 (username, tenant_id, NULL)
           , username
           );
  

  If username is NULL, then the two expressions of the index will be NULL and no index entry will be. So there may be a number any lines with the same tenant_id, but no user name, but only one line for each (tenant_id, username) combination when there is a user name.

  Good instinct; It's weird (but not necessarily bad) to have a one-to-one relationship between the tables, but do you? When you say things like

  ... A user name cannot be used once a TENANT...

  or

  ... As soon as I add a 2nd employee for a tenant...

  Looks like you have a one-to-many relationship, or maybe a many-to-many relationship, or maybe even two relationships, neither of which is unequivocal.
