Wrong auto-detection of relationships between tables/excludeDependencies doesn't work

I use obevo-db v7.2.0. There are 2 sqls which should generate DB tables: Account & WhitelistedAddress. Account.sql

//// CHANGE name=init_account
create table ACCOUNT
(
    CLIENT_ID           bigint    not null,
    WHITELISTED_ADDRESS varchar(64),
    COMP_ID             varchar(64),
    BEGIN_STRING        varchar(20),
    SUB_COMP_ID         varchar(64),
    LOCATION_ID         varchar(64),
    SYS_AUTH_ID         varchar(128),
    SYS_AUTH_SALT       varchar(64),
    SYS_AUTH_PWD        varchar(1024),
    CLIENT_TYPE int2,
    SYS_STAT int2,
    FROM_Z              timestamp not null,
    THRU_Z              timestamp not null,
    IN_Z                timestamp not null,
    OUT_Z               timestamp not null
);
GO

//// CHANGE name=add_pk
alter table ACCOUNT
    add constraint ACCOUNT_PK primary key (CLIENT_ID);
GO

//// CHANGE name=add_unq_client_id
alter table ACCOUNT ADD CONSTRAINT UNQ_CLIENT_ID UNIQUE (CLIENT_ID);
GO

//// CHANGE name=drop_whitelisted_address_column 
alter table ACCOUNT DROP COLUMN WHITELISTED_ADDRESS;
GO

Whitelisted_address.sql

//// CHANGE name=init_whitelisted_address
create table WHITELISTED_ADDRESS
(
    WHITELISTED_ADDRESS varchar(255) not null,
    CLIENT_ID           bigint
);
GO

//// CHANGE name=add_wl_pk
alter table WHITELISTED_ADDRESS add constraint WHITELISTED_ADDRESS_PK primary key (WHITELISTED_ADDRESS);
GO


//// CHANGE name=add_wl_fk
alter table WHITELISTED_ADDRESS add constraint WHITELISTED_ADDRESS_fk_0 foreign key (CLIENT_ID) references ACCOUNT(CLIENT_ID);
GO

//// CHANGE name=init_whitelisted_address_idx
create index WHITELISTED_ADDRESS_IDX0 on WHITELISTED_ADDRESS (CLIENT_ID);
GO

When I try to run deployment of DB by above scripts I got following issue:

com.gs.obevo.impl.graph.GraphCycleException: Found cycles for the changes below. Please correct the object content.
You can remediate by:
    A) manually excluding false dependencies using //// METADATA excludeDependencies=A,B,C or
    B) defining appropriate dependencies using the METADATA includeDependencies or dependencies attributes
It is helpful to analyze the EXPLICIT dependency types.

Changes are marked as [objectName.changeName]
Dependency Types: EXPLICIT = marked in code, IMPLICIT = from implied deploy order within incremental table changes

Cycle #1:
    [ACCOUNT.init_account]
    => [ACCOUNT.add_pk] (IMPLICIT)
    => [ACCOUNT.add_unq_client_id] (IMPLICIT)
    => [ACCOUNT.drop_whitelisted_address_column] (IMPLICIT)
    => [WHITELISTED_ADDRESS.add_wl_fk] (DISCOVERED)
    => [WHITELISTED_ADDRESS.init_whitelisted_address_idx] (IMPLICIT)
    => [ACCOUNT.init_account] (DISCOVERED) (CYCLE FORMED)

As you can see => [WHITELISTED_ADDRESS.add_wl_fk] (DISCOVERED) such auto-detected relationship was wrong, because all what I want is just remove WHITELISTED_ADDRESS column from Account table. This wrong auto-detection is first part of problem. Second part of problem that excludeDependencies doesn’t help me to resolve issue. I tried following change:

//// CHANGE name=drop_whitelisted_address_column excludeDependencies=WHITELISTED_ADDRESS
alter table ACCOUNT DROP COLUMN WHITELISTED_ADDRESS;

but it doesn’t have any effect. Obevo still resolves such statement as link to WHITELISTED_ADDRESS table.

What is the right way to use excludeDependencies?

Great to hear!

I’ll leave this ticket open to track the work to clarify the cycle error message

Hi, I was able to reproduce the issue using your example provided and found the issue

Please ignore my previous diagnosis; the case-sensitivity is not an issue. You can leave the file case upper-case as is

You have an implicit dependency in your init_account statement as well that you would need to exclude

//// CHANGE name=init_account
create table ACCOUNT
(
    CLIENT_ID           bigint    not null,
    WHITELISTED_ADDRESS varchar(64),

The cycle error message comes out a bit differently - the key line is the third line “[ACCOUNT.init_account] (DISCOVERED)”. DISCOVERED and EXPLICIT dependencies are the important ones to look at. (as an aside - the error message omits the DISCOVERED dependency type and only EXPLICIT; I will correct this)

Cycle #1:
    [WHITELISTED_ADDRESS.add_wl_fk]
    => [WHITELISTED_ADDRESS.init_whitelisted_address_idx] (IMPLICIT)
    => [ACCOUNT.init_account] (DISCOVERED)
    => [ACCOUNT.add_pk] (IMPLICIT)
    => [ACCOUNT.add_unq_client_id] (IMPLICIT)
    => [ACCOUNT.drop_whitelisted_address_column] (IMPLICIT)
    => [WHITELISTED_ADDRESS.add_wl_fk] (DISCOVERED) (CYCLE FORMED)

You can add the excludeDependencies to both the CHANGE entries in that file to fix it

//// CHANGE name=init_account excludeDependencies=WHITELISTED_ADDRESS
create table ACCOUNT
(
    CLIENT_ID           bigint    not null,
    WHITELISTED_ADDRESS varchar(64),

Let me know if that works for you
