Enabled Primary Key not reinforced in 7.2

Post by EmmanuelB » Wed Dec 09, 2015 11:34 am

Hi,

I have created a table like this :

Code: Select all

CREATE TABLE public.DIM_PAYS_TEST (
      CODE varchar(3) NOT NULL,
      CODE_NUM int NOT NULL,
      ALPHA2 varchar(2) NOT NULL,
      ALPHA3 varchar(3) NOT NULL,
      LIBELLE_FR varchar(100) NOT NULL,
      LIBELLE_EN varchar(100) NOT NULL,
      
      CONSTRAINT PK_DIM_PAYS_TEST PRIMARY KEY (CODE_NUM) ENABLED  
      
)
UNSEGMENTED ALL NODES 
KSAFE 1 ;
And loaded some data.

When I try to load the same data again using an ETL tool like SAP BusinessObject Data Services (ODBC) or Talend (JDBC), the data are loaded and therefore duplicated even if the constraint is enabled. But if I try a simple

Code: Select all

INSERT INTO public.DIM_PAYS_TEST (CODE,CODE_NUM,ALPHA2,ALPHA3,LIBELLE_FR,LIBELLE_EN) VALUES ('894','894'::Integer,'ZM','ZMB','Zambie','Zambia') ;
using another JDBC compliant client (like DbVisualizer) then I get a PK violation error.

How come the PK is not reinforced with the ETL tools, is there a connection parameter to add in the client configuration ?

Vertica does not enforce PK while loading to enable fast data loads. you have to manually check for PK violations.

Use this functions to check for violations.

Actually, as of 7.2, Vertica does enforce PRIMARY and UNIQUE constraints.

FYI ...

A hot fix for this issue is available in Vertica 7.2.1-4, which was released on on 02/25/2016!

Issue: VER-43961
Component: Sessions
Description: Enabled primary keys and unique keys were not enforced on a command issued from a JDBC or ODBC prepared
statement. This issue has been resolved.
