Dear CoreLab;

I had post about oracle constraints like [NOT NULL], and [UNIQUE key with more than one Columns], and I had told the this issue will be solve in the next build, I have download v 4.6 but the problem is still their,

When I build the dataset, and select my table, the wizard did not recognize Oracle constraints so well,
Not Null Constraint is not included,
UNIQUE key with 2 fields is defined as ((2 unique keys for each column)).

I believe that is a bug ….

I wait you fix for this bug, I hope it be ASAP.

Best Regards,

Ahmed P.Eng.

Oracle Table Structure:

Code: Select all

create table TEST
(
  OID     NUMBER not null,
  F_NAME  VARCHAR2(5) not null,
  L_NAME  VARCHAR2(5) not null,
  AGE     NUMBER not null,
  ADDRESS VARCHAR2(50)
);

alter table TEST add constraint TEST_PK primary key (OID);
alter table TEST add constraint TEST_UK unique (F_NAME, L_NAME);

The Generated Schema From Dataset Wizared(Look to the end of XML file you will find three constriant instead of two):

Code: Select all

  
    
      
        
          
        
        
          
            
              
                
                  
                    select * from HR.TEST
                    
                  
                
                
                  
                    INSERT INTO HR.TEST (OID, F_NAME, L_NAME, AGE, ADDRESS) VALUES (:OID, :F_NAME, :L_NAME, :AGE, :ADDRESS)
                    
                      
                      
                      
                      
                      
                    
                  
                
                
                  
                    UPDATE HR.TEST SET F_NAME = :F_NAME, L_NAME = :L_NAME, AGE = :AGE, ADDRESS = :ADDRESS WHERE OID = :Original_OID
                    
                      
                      
                      
                      
                      
                    
                  
                
                
                  
                    DELETE HR.TEST WHERE OID = :Original_OID

We reproduced the problem and now we are fixing it.
Look forward to the next build.

Hello,

I'm currently using version 4.75.43 and have the same multiple columns constraint problem. Do you know if it has been fixed in the newer versions?
Thanks

I have just checked the 5.25.38 version of dotConnect for Oracle. Here is the schema generated by DataSet Wizard for the TEST table from ahijazi's post:

Code: Select all

  
    
      
        
          
        
        
          
            
              
                
                  
                    select * from SCOTT.TEST
                    
                  
                
                
                  
                    INSERT INTO "SCOTT"."TEST" ("OID", "F_NAME", "L_NAME", "AGE", "ADDRESS") VALUES (:OID, :F_NAME, :L_NAME, :AGE, :ADDRESS)
                    
                      
                      
                      
                      
                      
                    
                  
                
                
                  
                    UPDATE "SCOTT"."TEST" SET "OID" = :OID, "F_NAME" = :F_NAME, "L_NAME" = :L_NAME, "AGE" = :AGE, "ADDRESS" = :ADDRESS WHERE (("OID" = :Original_OID) AND ("F_NAME" = :Original_F_NAME) AND ("L_NAME" = :Original_L_NAME) AND ("AGE" = :Original_AGE) AND ((:IsNull_ADDRESS = 1 AND "ADDRESS" IS NULL) OR ("ADDRESS" = :Original_ADDRESS)))
                    
                      
                      
                      
                      
                      
                      
                      
                      
                      
                      
                      
                    
                  
                
                
                  
                    DELETE FROM "SCOTT"."TEST" WHERE (("OID" = :Original_OID) AND ("F_NAME" = :Original_F_NAME) AND ("L_NAME" = :Original_L_NAME) AND ("AGE" = :Original_AGE) AND ((:IsNull_ADDRESS = 1 AND "ADDRESS" IS NULL) OR ("ADDRESS" = :Original_ADDRESS)))

There are two constraints generated by DataSet Wizard now, not three. Is that what you mean?

Yes, this is what I need. So I guess I'll need to upgrade.

Thanks for the quick reply.

Checked with the newer versions and the problem still persists: when using the DataSet Wizard, the schema is indeed filled correctly. However, when using the OracleDataAdapter.FillSchema() method, the constraints are rendered the wrong way(separately). Any thoughts?

We reproduced the problem. We will investigate it and notify you about the results.

Great, thank you very much. Looking forward to it.

We fixed the problem. The fix will be available in the nearest build, which we plan to release in the end of the month.
