Vertica update fails with "DATABASECHANGELOG" already exists

[nicopadu]

Environment

Liquibase Version: 4.4.3

Liquibase Integration & Version: CLI

Liquibase Extension(s) & Version: liquibase-verticaDatabase-4.4.3.jar

Database Vendor & Version:

• Vertica verticadocker/vertica-ce:10.1.1-0
• vertica-jdbc-10.1.1-0.jar

Operating System Type & Version: Liquibase (Ubuntu 20.04), Vertica (docker image)

Description

Update command only works if database name, schema and username are all aligned with same value.
In case that any of them has a different value following error occurs:

• created tables might be created in default public schema (ignoring schema parameters - if database name and schema are not the same)
• in all cases fails after second update command with error Unexpected error running Liquibase: [Vertica][VJDBC](4213) ROLLBACK: Object "DATABASECHANGELOG" already exists

Steps To Reproduce

Using vertica-ce docker image from here: https://hub.docker.com/r/verticadocker/vertica-ce

# run vertica (creates a defulat 'vmart' database)
docker run -d -p 5433:5433 --env APP_DB_USER='my_user' --env APP_DB_PASSWORD='my_pass' --name vertica_ce verticadocker/vertica-ce:10.1.1-0

# create a sample schema
docker exec vertica_ce /opt/vertica/bin/vsql -c "CREATE SCHEMA my_schema;"

this is the content of liquibase.properties

liquibase.hub.mode=off
changeLogFile=./changelog/changelog.xml
liquibase.liquibaseTablespaceName=my_schema
liquibase.liquibaseCatalogName=my_schema
liquibase.liquibaseSchemaName=my_schema
liquibase.command.defaultSchemaName=my_schema
liquibase.command.defaultCatalogName=my_schema

this is the changelog.xml

second update command -- fail

bin/liquibase update --url=jdbc:vertica://localhost:5433/vmart --username=my_user --password=my_pass

Unexpected error running Liquibase: [Vertica][VJDBC](4213) ROLLBACK: Object "DATABASECHANGELOG" already exists

Actual Behavior

Database, Schema and Username are different:

• database: vmart
• schema: my_schema
• userbame: my_user
• sample command: bin/liquibase update --url=jdbc:vertica://localhost:5433/vmart --username=my_user --password=my_pass

DATABASECHANGELOG & DATABASECHANGELOGLOCK tables are created in schema "my_schema", but target table "t1" is created in default "public" schema.
Second execution of update command fails with Object "DATABASECHANGELOG" already exists
Probably related to liquibase/liquibase#2030

Database, Schema and Username all with same value

In case all values are the same, full procedure works... unfortunately this enforces a very rigid configuration

Steps to make it run:

# create a new schema with same name as user
docker exec vertica_ce /opt/vertica/bin/vsql -c "CREATE SCHEMA my_user;"

update liquibase.properties with following values:

liquibase.hub.mode=off
changeLogFile=./changelog/changelog.xml
liquibase.liquibaseTablespaceName=my_user
liquibase.liquibaseCatalogName=my_user
liquibase.liquibaseSchemaName=my_user
liquibase.command.defaultSchemaName=my_user
liquibase.command.defaultCatalogName=my_user

run update command

bin/liquibase update --url=jdbc:vertica://localhost:5433/my_user --username=my_user --password=my_pass

...
Starting Liquibase at 00:00:00 (version 4.4.3 #53 built at 2021-08-05 18:32+0000)
Liquibase Version: 4.4.3
Liquibase Community 4.4.3 by Datical
checking for vertica
Liquibase command 'update' was executed successfully.

following update command works as expected. all tables are created under schema "my_user"

Expected/Desired Behavior

Ideally users should be able to configure independent values for db name, schema and username

Hi Nicolas, how are you?
Were you able to solve the "DATABASECHANGELOG" already exists problem?

[nicopadu]

Hi Larissa, nop we were not able to fix it. We're still with the known way of keeping schema & username with same value

[acscott]

I ran into the same issue and resolved it by making the login user to SQL Server a member of the role db_owner

[hanee-shousha]

Hi @nicopadu and @larissavmss ,
I was getting same error like you for the DATABASECHANGELOG already exists, but I have tried only the parameter below with both liquibase and liquibase-vertica jar version 4.26.0 and it works now successfully.

liquibase.liquibaseSchemaName=public
