Inline Y field check constraint. N
I created a domain with a list of values (Y or N) and used this area of a column in a table.
Helped the 'use area Constraints' and tick appears in the DOF as a 'Alter table add constraint without name.
I'd rather have this constraint as an inline constraint. How can I say DM to do this?
With the help of the DM Version 4.0.3.853
Select Preferences from the Tools menu.
In the left panel of the Preferences dialog box, select Data Modeler > DDL and select the option 'generate Inline column constraints validation.

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.

Field use constraint does not generate a constraint name
Hello
I use a domain for which I've specified a check constraint. In the standard naming model, I set a model for the column check constraint.
Now, if I'm modeling a table in the relational model (not derived from the logic model) and specify a column with the given domain name, after checking the "use area constraints' I wouldn't be a generated named check constraint. The check constraint is generated in the DDL as inline check constraint.
Any suspicion or makes the model for the work of column check constraint?
Thanks in advance,
puchtec
Operating system: Windows XP 32-bit
Product version: 2.0.0.584Hello puchtec,
In the standard naming model, I set a model for the column check constraint
You must also apply templates - you can do it for a single table in the table dialog box or model relational set - menu drop down for relational model in the browser.

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.
* Cause: an alter table operation tried to validate a check constraint to
populated table that has nocomplying values.
Can you suggest me work around him?
Kind regards

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.

Problem: by dropping a Table Check constraint
I got a check from a table constraint in my model. Then wanted to synchronize data dictionary. The comparison of models- dialogue see the difference, but as I check the box drop -(which is unchecked by default) and click the DOF preview preview is empty. I mean it's totally empty, not even the ddl-comments standard as

show up! So I guess that this behavior as a bug.

Hi Dieter,
Thanks for reporting this problem. I connected a bug on this issue.
Note that this problem does not occur for check constraints that are defined in the definition of a column. It only occurs to verify the constraints defined at the Table level.

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.

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:

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

How to use current date in the check constraint

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... :)

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

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.

Please can I get some help with a check constraint.
The Table is called the TITLE and the attribute is TI_RELDATE (a date). I am wanting to make sure that it is between 1930 and the date of the day.
Is this something like this:
CONSTRAINT TITLE_ck_TI_RELDATE CHECK (TI_RELDATE between 1930 and GETDATE())
CanningGETDATE()-based you come from the side of SQL Server of the barrier. Literals in Oracle date are 'yyyy-mm-dd ". Now the part 'getdate '. What exactly are you trying to do? Make sure that the inserted/updated date to date is not a later date? If so, you need a trigger for this. Check constraint can do is make sure you inserted/updated date is 1930 or higher:
alter table tbl add constraint tbl_chk1 check( dt >= date '1930-01-01' ) /
Switch to make sure that the inserted/updated date to date is not a later date:
create or replace trigger tbl_bir before insert or update of tbl for each row begin if dt > sysdate then raise_application_error(-20900,'Column dt value can't be a future date.'); end if; end; /

Oracle 11 R2
My question is if I can create a check constraint using a SELECT statement on a different table?

I can do something like this:
