• HP question first basic use - how can I enter constraints?

  I would like to be able to specify constraints for graphical representation of a function, a function of problems. Let us look at the graphic representation first. For example, I would draw sin(x) a specific interval such as halves of the halves negative pi positive pi. On a TI-nSpire, the vertical bar is used as a symbol to do this kind of thing - sin (x) |-pi/2 < x < pi/2. where pi is the symbol for pi.

  I don't know if there is another way to do it, but using the case model would work.  0/0 makes the function not defined outside the - pi / 2 and pi/2 limits.  If you want, after you enter the model, the function can be edited and "0/0" can be removed.

  

• Cluster for the FPGA reference constraint

  I have a cluster of clusters.  One of the internal piles went 25-29 items, but I forgot to update several of my Subvi reflect.  I remember before when I did, I got a broken line not executable VI, but now the result is a constraint.  You can really force a cluster with multiple items to a cluster with fewer items?  My outdoor group consists of some FPGA with clusters of register references.

  Hi Adams,

  FPGA reference is the special data of type "FPGA dynamic reference", which includes a cluster of records, elements, and associated with the referenced FPGA personality FIFO dynamically. Dynamic data types do not follow the same rules of coercion expected of them a defined data type statically to follow. The dynamic nature of reference FPGA son allow wire any FPGA reference in the entry of an order of read/write, regardless of whether the control of read/write was created explicility for the FPGA reference. This makes it much more practical FPGA programming.

• CA and naming constraints

  We are currently upgrading our PKI for SHA2 support and make some changes. We have a root AD and 2 child domains (PROD and DEV).

  We have a certification authority root offline, substitute Enterprise (signed by the root) in the field of PROD. We intend to install a second Sub company in the DEV field (with limited models). Tests show that this could work.

  Problem is that we are trying to set the policy for the DEV CA. We want to assure you that it could not issue certificates for *. pkiprod.my.test Kingdom.

  Thus, at the signing of the sub CA, we apply a policy file:

  [Version]
  Signature = ' NT $Windows $.

  [NameConstraintsExtension]
  Include = NameConstraintsPermitted
  Exclude the = NameConstraintsExcluded
  Criticism = True

  [NameConstraintsPermitted]

  [NameConstraintsExcluded]
  DNS =. pkiprod.my.test
  UPN =. pkiprod.my.test
  DIRECTORYNAME = "dc = pkiprod, dc =, dc = test.
  URL =. pkiprod.my.test

  Under CA show Naming constraints.

  The certification authority, it is still possible to the certificate problem with. pkiprod.my.test.

  Change the policy file to include:

  [NameConstraintsPermitted]
  DNS =. pkidev.my.test
  UPN =. pkidev.my.test
  DIRECTORYNAME = "dc = pkidev, dc =, dc = test.
  URL =. pkidev.my.test

  On the Sub result CA are different:

  We cannot issue a certificate with. pkiprod.my.test (he said clearly refuse due to the policy)

  And we cannot issue a certificate with. pkidev.my.test (event without extension as Mywebsite)

  These tests are using a model of certificate as approval of registration.

  If we try with a model who only read permission (must be manually problem) demand in the MMC does not show a naming constraint in the extensions and deliver when it failed.

  How can properly configure us the sub CA to make sure it will never issue certificate for. pkiprod.my.test?

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• REF. order. give the constraint when built in table

  I have a front face with (IMO) too many controls. To help cope with all of them, I build an arrary of references I can index or move to submarines. However, I noticed that each Ref control produces a point constraint when building them in a table. Two questions:

  (1) is there a way to avoid this? and

  (2) otherwise, it will cause problems later if I will try to find a specific comparing to the other refs of control?

  

  (1) none

  (2) Yes (maybe)

  All the elements in an array can differ only by their value. The point of constraint tells you that these references are cast from a generic type. If you rely on the ref is a specific type, then you can run in question.

  Rather than building a table, I suggest the creation of a cluster (def of type a) with the appropriate Ref types. This makes my development because I can't count to find a ref, I can just take in a list (ungroup by name).

  Just trying to help,

• Insert the CK error | CKM | Check constraint is not picked up by ODI11g

  I'm trying to hit a stage in CKM 'insert error CK' and it is always checked "run" and there is not so other condition in the code

  I've created an interface that has activated the Frother and target constraint check (no constraint check in ODI datastore)

  Now how should be my designed interface for my "insert error CK' step executed?

  Sorry, I wrote too fast on this one, I'm not sure of the Oracle RKM's check of reverse engineering constraints. It may be only PKs, FKs and constraints not null.

  CHECK in ODI constraints are called "Conditions". You can add it by expanding your data store in the left pane and right-click on the constraints:

• Oracle 12 c, the best way to add a foreign constraints on a property to json

  Hi, I wonder what is the best way to achieve a foreign constraint in this situation:

  In TABLE_A there is a column CLOB with the constraint "check is JSON.

  Is it possible to create a foreign key on a column property of json that references a column (primary key) on another table?

  Is it possible to create a constraint on a column property json referencing a property of another JSON column on another table?

  Currently, I do as well using a trigger, or by adding a column copy the value of the property of json which I need the constraint.

  Are there other ways to do this?

  Thank you!.

  Supported JSON is relatively new for Oracle 12 c.

  Is it possible to create a foreign key on a column property of json that references a column (primary key) on another table?

  Is it possible to create a constraint on a property of the column of json that refers to a property of another JSON column on another table?

  As I know there is no way to create a constraint on a property JSON in a column. Part of the issue with JSON is that not all properties are required to be present in the JSON document. What would you do if these goods were missing?

  Currently, I do as well using a trigger, or by adding a column copy the value of the property of json which I need the constraint.

  That's how I'd do. If you have a JSON property that must be part of a constraint, use a trigger to fill another column, then put the constraint on this column.

  See you soon,.

• Data Modeler adds NO CASCADE CONSTRAINTS when deleting views

• ODI is recovering not Unique key constraint

  I created a table with script below and reverse engineering it.

  create table test
  (primary_id number,
   unique_not_null_ID number not null,
    col3 number,
   col4 varchar2(200),
   col5 varchar2(2000),
  primary key (primary_id),
  unique (unique_not_null_ID) 
  )
  

  But all looking in the constraint of the data store only the primary key is here

  Also, within the quick edit tab Interface is show

  (1) Primary_id: = UK and CN of check

  (2) Unique_not_null_id: = CN is the Coachman

  
  

  So, why there no Unique constraint picked up?

  
  

  I think then it will only mark it too fast Edition.
  

  Hi spear,

  Please note that during standard reverse engineering unique keys are not reverse engineering. Then you need to either do reverse engineering on measurement or add a unique touch to the ODI level.

• correct handling of foreign keys in unique constraints for operations ON DELETE SET NULL

  During my troubleshooting at a client site, I came across an interesting setup where I would like to ask your opinion.

  
  Consider two tables ADTB and TBLB.

  ADTB:

  INT COLA1

  COLA2 INT

  TBLB:

  COLB1 INT

  COLA2 is COLB1 as a foreign key ON DELETE SET NULL value.

  COLA1 and COLA2 are combined into a UNIQUE for the BATTERY constraint.

  I have two records of TBLB:

  (1)

  (2)

  and two DRUM recordings:

  (1, 1)

  (2, 2)

  so far, all the constraints are valid.

  During my research, I learned that I can not put COLA2 null in ADTB for two lines at the same time:

  TBLA UPDATE set COLA2 = NULL where COLA1 = 1;

  -> OK

  TBLA UPDATE set COLA2 = NULL where COLA1 = 2;

  -> VIOLATED UNIQUE CONSTRAINT

  Unfortunately, it's something my application needs, anyway. In order to get this resolved, but I try to understand, what would happen if I:

  REMOVE THE TBLB;

  ?

  It should set COLA2 in ADTB "Null" on the two lines, which is not allowed due to the UNIQUE CONSTRAINT.

  Can someone shed light on this issue? Thank you.

  
  Yours,

  Ronny

  Unfortunately, as you say, you can't not NULL values in such a unique constraint.  It would be the same as if you had a composite primary key and try to allow one of the columns will be null in several rows with the same value in the other column.  NULL is treated as an "unknown" value, it is possible that it could be the same value (it may or may not be, but Oracle does not know), so it must assume that it might be and that's why treat it as if there is the potential for a duplicate... so it's not unique.

  In short, do not allow null values in your unique constraints.

  The default is in the drawing, not in the way that Oracle is the treatment.  Fix the design if you do not have NULL values.

  In terms of relational database design, it seems that you are trying to transform the 1:M relations M:M relations, and which requires an intermediate table if you have M:1 and 1:M between 3 tables instead.

• Foreign key constraint, not recognized during the synchronization of data with the model dictionary

  Hello

  Data Modeler is a foreign key constraints do not recognize when synchronizing data with the model dictionary, although the foreign key is there (in the database that a data dictionary is read). I can't find any criterion when a foreign key is not recognized by the Data Modeler. Are there limits to the length of the attribute, or the number of columns in a foreign key, or other limitations which may lead to this behavior not to recognize a fk by Data Modeler? I have columns more than 32 characters. I compared with the fk is recognized by DM, but I can't find anything that indicates why it is not recognized.

  I wonder if someone also has constraints of foreign keys that are not recognized in the comparison of data bases and model?

  Thank you

• disable the constraint

  Hello

  to remove an index PK I disabled the constraint.

  CHANGE TABLE DISABLE CONSTRAINT MAKEY_PK MYTABLE CASCADE;

  Now I'll recreate this KP index.

  Should I do something more to have the same constraints where they were?

  Thank you.

  Just re-create the index and select the constraint.
