• Problem in creating the CHECK constraint

  When creating a table, I want to apply a CHECK constraint, that pension_amount must be in accordance with pension_code, I get the below error.

  CREATE TABLE pension_amount_check
  (
     pension_amount         NUMBER (4),
     pension_code   NUMBER (1),
     CONSTRAINT amount_chk CHECK
        (CASE
            WHEN pension_code = 1 THEN (pension_amount = 3000 OR pension_amount > 3000)
            WHEN pension_code = 2 THEN pension_amount = 1500
         end)
  )

  How I can solve this problem.

  Hello

  So you cann which adds another.

    PENSION_AMOUNT  NUMBER(4),
    PENSION_CODE    NUMBER(1)
  )

    CONSTRAINT SSSSSS
    CHECK (((pension_code =1) AND  (pension_amount = 3000 OR pension_amount > 3000)) OR (  (pension_code =1)  AND  pension_amount = 1500))  ENABLE NOVALIDATE)

  There are some workaround solutions...

  And to add, that your mistake here is different - you're talking about another column JDATE (typo..?) in the check constraint... The actual column name is ADATE... :)

• modify the check constraint

  Hello friends...
  I want to edit the check constraint... It is possible to modify the check constraint?
  
  
  ALTER TABLE table_name
  change (CONSTRAINT constr_name CHECK (yes_no_col_name IN ('n', 'Y')))
  
  It gives me
  
  name of the constraint that is already in use
  
  
  Thank you...

  You can't modify a check constraint. You can only change its State.

• You will need to validate the format of the time 24 hours with the check constraint.

  Rgds,

  Athuru Mithuru.

  Let's start by defining precisely what you want.  For example

  1. The 1st character can be 0, 1, or 2.
  2. The 2nd character can be any number EXCEPT if the 1st character is '2', then the 2nd character must be in the range ' 0 'to 3'.
  3. The 3rd character can be '0' and '5'
  4. The 4th character can be any digit.

  It's pretty simple code like a regular expression with the exception of the exception in the 2.   Here's a way to get around that:

  REGEXP_LIKE (law on the)

  , ' (' || -options for the first 2 digits of start

  "([01][0-9])' |" --0 or 1, followed by another digit

  '| (2[0-3])'    || -2 followed by 0, 1, 2 or 3

  ')'              || -end of the options for the first 2 digits

  '[0-5]'          || -any digit between 0 and 5

  '[0-9]' - a figure

  )

  As others have said, think about the type of data.  How will you use this column?  If you really need a column which reflects a time of day, but not special, then perhaps an INTERVAL, or a NUMBER (for example, the number of hours after midnight) rather than a string.

• Several multiple conditions can be given in the check constraint

  Hello
  
  I am agent table where the city and the commission is there. When inserting records, I need to apply a rule that if the city is London commission cannot be less than 300. Can it be done using validation constraints? I was able to do so using PL/SQL. I just want to know if it could be done using validation constraints. If so, then need please the syntax.

  Try like this

  create table test1
  (varchar2 (100) of the city)
  Commission number,
  check test_name forced ((ville = 'London' et commission > = 300) or city! = 'London'));

• Understand the Check constraint

  CREATE TABLE sample_table

  (

  Id1 NUMBER CHECK (id1 > 9),

  Name1 VARCHAR2 (10)

  )

  INSERT INTO sample_table

  VALUES (11, 'Name')

  Inserted successfully

  INSERT INTO sample_table

  VALUES('','Name')

  How did the last insert statement gives me error.

  I mean > 9 Null is not true or is it?

  The columns you stated is also null-able, try this

  CREATE TABLE sample_table

  (

  Id1 NUMBER CHECK (id1 > 9) not null,

  Name1 VARCHAR2 (10)

  )

• Addition of the Check constraint, while avoiding checking data existsing

  Dear Sir
  
  Is there an option in oracle for verification of transmissions to avoid checking existing data?
  
  For example: Emp incudes data in table, the table are changed as follows:
  
  change the emp table add constraint emp_ck2 check (salary > 2500);
  
  Wages in the table has values less than 2500, so of course, I get an error...
  
  Is it possible to prevent checking of existing data? and the constraint should apply only to the newly added data?
  
  [Note that I thing there is something similar in T - SQL is called WITH No. CHECK, but donno on Oracle]
  
  The comments appreciated.
  
  Thank you very much...

  NOVALIDATE?

  alter table emp add constraint emp_ck2 check (sal > 2500) novalidate ;
  

  Refer to the manual

• DDL generation gets the CHECK constraint on each column in each table

  I'm exporting to the DDL and get:
  CHECK (phone_type ('FAX', 'HOTLINE', 'CONSUMPTION', 'PRIMARY', 'TTY_TDD')
  On EACH column of EACH table.
  Even in PHONE_TYPE column in the FACILITY_TELEPHONE_NUMBERS table, I deleted the list of values - I think I'll create a lookup table instead.
  
  Anyone have this happen to them? What do you have on this?

  You must edit the defaultdomains.xml file in the datamodeler\datamodeler\types directory.

  You should look for something similar in the definition of 'unknown ': domain

  remove it.

• Conceptual issue to create the client component

  Hi all

  I think most of you know how to create a component client, who is to inherit certain standard components for his behavior. But when I do this, for example

  public class ToggleButton extends button

  However, the metadata of the button is not in this new ToggleButton that is reasonable. So I copy all these definition, but the new problem is there is some files included in the metadata of the button that makes the problem more complex.

  Can we have an easier way to do this?

  Thank you

• Get a NAMED check constraint when the entity attribute derived from the field

  I'm designing a new database and beginning with a logic model of the ER. I've defined several areas, such as the NO_YES field (with values of ' no and 'Y'). When I use this area as a data type of an attribute of the entity (for example, the CHANGE_REQUEST.IS_APPROVED attribute), I also specify a constraint name (for example, CR_APPROVED_CK) of the attribute (this is done in the Group of constraint, property name constraint and the properties of the attribute dialog box, default value).
  
  When I have the logic model to a relational model of the engineer, the constraint name is lost. Specifically, for the definition of the table that is created, for the column in question, in the default column properties and constraints Panel dialog box, the name of constraint property is empty. When I generated the DDL of the relational model, the check constraint that is generated is an inline check constraint (such as ' IS_APPROVED VARCHAR2 (1) CHECK (IS_APPROVED IN ('n', 'Y')) '). When this DDL is executed to generate database objects, the created check constraint has a system-generated name. I want the constraint to have a name that I create.
  
  By experimentation, I found that in the relational model, if I specify a value for the property name of the constraint in the DOF resulting constraint get named (an ALTER TABLE statement is generated that contains "ADD CONSTRAINT CR_APPROVED_CK CHECK (IS_APPROVED IN ('n', 'Y'))"). However, I have redundantly change the relational model in the same way that I edited the logic model to specify the constraint names.
  
  Is there a way to guarantee that the constraint names defined in a logic model transferred during the engineering of a logic model to a physical model.
  
  The version of the Data Modeler I use is 3.0.0.665.

  Is there a way to guarantee that the constraint names defined in a logic model transferred during the engineering of a logic model to a physical model.

  There is ' compare/copy options' tab in the technical dialogue - clear the checkbox "do not apply to new objects.

• CHECK constraint question

  Oracle 11 R2
  
  My question is if I can create a check constraint using a SELECT statement on a different table?
  
  So instead of
  
  CHECK (building ('01', ' 02', ' 03'));
  
  I can do something like this:
  
  CHECK (select distinct from the other table);
  
  Example of welcome.

  I'm just checking if the building is in the other table. Is a foreign key must use the same columns as the primary key? Or I can use a foreign key with ALL the columns from the other table?

  A unique key will do.

• using check constraints

  Hi, I tried to create the check with the following requirement constraint
  I have a table

  create table checkcon_check (id ,tentnm ,virtual_id )
  as
  select 1,'ANHUB',100 FROM DUAL UNION ALL
  SELECT 2,'BHUB',200 FROM DUAL ;

  and I want the condition: If tentnm is like '% HUB %' then virtual_id must not be null
  Could it be possible using Check constraints
  
  and I tried the following but did ' t work
  Please help me in this
  

  ALTER TABLE checkcon_check add constraint chkchk check(select case when tentnm like '%HUB%'
