• How to get the a table check constraint.

  I don't see the function to get forced check.
  I try the table.getCheckConstraints () function
  but I return nothing.

  Hello

  table.getCheckConstraints () will return to check the constraints defined at the Table level in the Data Modeler.

  You can also call column.getCheck (). This will return a check constraint defined on a column object in the Data Modeler.

• Table check constraint

  Hello
  
  I am currently using a database of 11.2 and I can't try to simplify a check constraint. I've been using decodes, but obtaining them ugly and not very readable.
  CASE
  WHEN resource_type_key = "U".
  AND interface_name IS NOT NULL
  Resource_name IS NULL AND
  AND resource_full_path_name IS NULL THEN 'valid '.
  WHEN resource_type_key <>'U '.
  AND interface_name IS NULL
  AND resource_name IS NOT NULL
  AND resource_full_path_name IS NOT NULL THEN 'valid '.
  ELSE 'Invalid '.
  END
  
  Any suggestions?

  You must provide an expression that evaluates to true if valid, FALSE otherwise.

  I suggest somehting more like:

  CHECK((
  resource_type_key = 'U'
  AND interface_name IS NOT NULL
  AND resource_name IS NULL
  AND resource_full_path_name IS NULL)
  OR (resource_type_key !='U'
  AND interface_name IS NULL
  AND resource_name IS NOT NULL
  AND resource_full_path_name IS NOT NULL))

• BAD RESULTS WITH OUTER JOINS AND TABLES WITH A CHECK CONSTRAINT

  HII All,
  Could any such a me when we encounter this bug? Please help me with a simple example so that I can search for them in my PB.
  
  
  Bug:-8447623
  
  Bug / / Desc: BAD RESULTS WITH OUTER JOINS AND TABLES WITH a CHECK CONSTRAINT
  
  
  I ran the outer joins with check queries constraint 11G 11.1.0.7.0 and 10 g 2, but the result is the same. Need to know the scenario where I will face this bug of your experts and people who have already experienced this bug.
  
  
  Version: -.
  

  SQL> select * from v$version;
  
  BANNER
  --------------------------------------------------------------------------------
  Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production

  CORE    11.1.0.7.0      Production
  TNS for Solaris: Version 11.1.0.7.0 - Production
  NLSRTL Version 11.1.0.7.0 - Production

  Why do you not use the description of the bug test case in Metalink (we obviously can't post it here because it would violate the copyright of Metalink)? Your test case is not a candidate for the elimination of the join, so he did not have the bug.

  Have you really read the description of the bug in Metalink rather than just looking at the title of the bug? The bug itself is quite clear that a query plan that involves the elimination of the join is a necessary condition. The title of bug nothing will never tell the whole story.

  If you try to work through a few tens of thousands of bugs in 11.1.0.7, of which many are not published, trying to determine whether your application would be affected by the bug? Wouldn't be order of magnitude easier to upgrade the application to 11.1.0.7 in a test environment and test the application to see what, if anything, breaks? Understand that the vast majority of the problems that people experience during an upgrade are not the result of bugs - they are the result of changes in behaviour documented as changes in query plans. And among those who encounter bugs, a relatively large fraction of the new variety. Even if you have completed the Herculean task of verifying each bug on your code base, which would not significantly easier upgrade. In addition, at the time wherever you actually performed this analysis, Oracle reportedly released 3 or 4 new versions.

  And at this stage would be unwise to consider an upgrade to 11.2?

• CHECK constraint

  Hello experts,

  I am new to oracle using sql developer in windows 7.i have a problem in which I must first make two tables:

  Tbl_State (S_Id, S_Name, Country_Id)

  and

  tbl_City (C_Id, C_Name, State_Id)

  .

  I have to add a constraint to the tbl_city table so that it can accept only State_Id column values that are exist in the S_Id column in tbl_state. In that I tried to add a sub to mach check constraint query the values of tbl_state. S_Id but I think that Oracle sql does not query sub in the check constraint. Give me a suggestion how to fix this problem.

• How to create Check Constraint that act as a foreign key?

  Hi all
  
  
  I have table EMP and Dept.
  
  Can you give me "check constraint" sample for that when I get a (status = 'active') PGE unmatched entered DEPT., the process fails?
  It will allow to enter the EMP with status = 'inactive' only even if no corresponding entry in the DEPT. Then foreign_key will not apply.
  
  
  Thank you very much

  I don't see why the performance should be a problem.

  But the Council would always be to test your situation.

• Application of a CHECK constraint

  Watch as you try to implement an implication of the form "A implies B", where

  A is for old_nic_no is not null', and
  B stands for "length (old_nic_no) = 13.

  An expression of the form "A implies B" is + logically equivalent to the phrase "not A or B.
  Then you can try this:

  {code}
  check (old_nic_no is null or length (old_nic_no) = 13)
  {code}

• Issue by creating the Check constraint

  Hi Experts,

  I have obligation to create a check on a column constraint (Number (6.2)) is where in the max value must be less than 4000.

  But the column already has the data of more than 4000. Also, I can't delete the data that is already present in the table.

  I'm just using an alter command

  SQL > alter table test add check constraint CC_A (an < 4000);

  Error is:

  SQL error: ORA-02293: cannot validate (CC_A) - violated check constraint

  02293 00000 - "can't validate (s.%s) - violated check constraint.

  Can you suggest me work around him?

  You can specify NOVALIDATE ACTIVATE when you create the constraint.

  ALTER TABLE test

  ADD CONSTRAINT cc_a CHECK (one<>

  ENABLE NOVALIDATE

  ;

  The constraint does not apply to the values already in the table, but if you update a column where the condition is violated, the constraint applies to the new value.

• Customized using regexp check constraint

  Oracle 11.2.0.1

  I need a customized using regexp expressions check constraint.  We have a single column in our table REGNO, which is used to keep the registration number of our customers.  It has alpha and numeric values, the first is Alpha and rest is digital with preceding zeros as A0100 A1245, C1111 etc.  Sometimes, in the application user enters regnos evil if we want to stop entering the bad regnos i.e. assume that the user name is Ashok Kumar and in the series, we have 1000 users so this new user should have A1001 (other than any value A1001, in this example, the constraint must be limit to enter the value) only, not the others nor a1001 , A1000, nor A1002 or < has no > 1001 too. Rather than having 26 sequences (A to Z), we get a table where we have these columns:

  Alpha char (1), number of LastNo.  But sometimes a user enters wrong number value and stores it in the table, so next time for the same gap alpha arrives and confusing.

  So, we must have a constraint of database level so that ONLY the correct values must be entered.

  Kindly help me how I have this task please.

  Thank you.

  If REGNO is a derived value then why let you the user enter a value. Just generate the user.

• Regexp_like with check constraint

  Hi all
  
  My requirement is user does not enter data such as (½, ¼,...).
  I created the table with the constraint validation with the following syntax:
  
  
  CREATE TABLE mytest (c1 VARCHAR2 (20),)
  CHECK (REGEXP_LIKE(c1,'^[[:alnum:]+[:digit:]+[!@#]]+$')));)
  
  The means above, except alphanumeric, should enable figures and characters from the keyboard. But it does not have any character.
  
  Please help me, any error in the syntax above.
  
  Thank you

  Alnum already includes numbers well, you don't need to Pack! @# in [] within []:

• 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 ;

  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... :)
