I was trying to create a MySQL table with a column type "DateTime(3)" by using Liquibase changelog, e.g. <column name="dateTimeColumn" type="DateTime(3)">. However, The output of data type is always "DateTime" (Fractional seconds disappered). But, when I changed the type to "Timestamp(3)", it worked. Anyone know what is the problem ? Please advice.

Forgive the SQL newbie here. DBA stated we needed to commit each statement with a GO. It works from TSQL in management studio, just not liquibase. Any help is appreciated. 

Example

Drop column table 1 
GO

Drop column table 2 
GO

Tried 
<sql endDelimiter="\nGO" splitStatements="true">
Drop column table 1 

Drop column table 2 
</sql>
Try 2
<sql endDelimiter="GO" splitStatements="true">
Drop column table 1 

Drop column table 2 
</sql>
Try 3
<sql>
Drop column table 1 

Drop column table 2 
</sql>
Try 4
<sql endDelimiter="GO" splitStatements="true">
Drop column table 1 
GO

Drop column table 2 
GO
</sql>

Error using YAML format

Hi, I'm using liquibase 3.5.4 on fedora 26, and I trying to use YAML format but I get this error in a update command:

I have the file "snakeyaml-1.17.jar" in the lib folder but it seems that is not read. I try to change permissions (read, execution...) but nothing change. In xml format works great.

With version 3.6.1 I have a similar error:

I also have the corrects files (logback-classic-1.2.3.jar, logback-core-1.2.3.jar, slf4j-api-1.7.25.jar, snakeyaml-1.18.jar) in the lib folder. In this version no command works.

Any idea? Thanks.

The first thing I would check is the liquibase shell script. It uses or sets a variable LIQUIBASE_HOME - you might add or uncomment some things in that shell script to ensure it is using the locations and jars you think it should be using. 

I'll sometimes change the last few lines of that shell script to look like this:

  1. MY_CMD="java -cp \"$CP\" $JAVA_OPTS liquibase.integration.commandline.Main ${1+\"$@\"}"
  2. echo $MY_CMD
  3. $MY_CMD
This is basically the same as the default last line, but set into a variable. It has to be quoted, so the existing double quotes have to be escaped. It then echos the command and then executes it, making it easy to see what the classpath being used is.

The problem was in runnig the application from the .jar with the command:

The liquibase command solve the error.

Liquibase changing type of primary key

April 13, 2018, 4:30 am
$

Having generated a changelog on a current database, I have attempted to create a new database from that changelog. After a fair few problems probably related to our database structure, I've come across some strange behaviour.

When adding a primary key to a table consisting of two columns, the type of the column is changed from smallint(5) to int(11).

When adding a foreign key later in the script, this fails as the type of the two tables does not match anymore.

Any information as to why liquibase does that and how to prevent it from changing the type when adding a primary key? I can't find any mention of it in the docs or any other mention of this behaviour online.

Liquibase and several schemas best practices

April 15, 2018, 1:52 pm
$

I am using Liquibase on DB with several schemas. Those schemas has foreign keys to each other.
What is a best practise for such use case with Liquibase?

Currently migration files are separated in folders by schema. Each schema has its own changeset-master.xml. 
In this case I loose ability to create schema from scratch. Creating FK to other schemas should be preconditioned "CONTINUE" to columnExists and created on second run.

Is it better to have one big changeset-master.xml for the whole DB? In this case, where to place tables databasechangelog and databasechangeloglock?

Hi Adam,

it could be that the RDBMS-specific code for that has changed. Can you tell me which RDBMS (PostgreSQL/MariaDB/MSSQL/...) you are using, which Liquibase version the old behaviour showed, and since which Liquibase version you are seeing the different data type?

Kind regards,
Andreas

Hi Andreas,

Thanks for the reply. I'm using MariaDB and the latest version of Liquibase. I'm currently testing Liquibase for use at my place of work so have no previous version. The changelogs are generated from the Liquibase command.

Had a look at this again this morning and managed to fix this by changing the columnDataType to SMALLINT(5) UNSIGNED in the addAutoIncrement section. Seems to be working as intended now. Probably user error to be honest.

Ok, just so that I have a test case I can reproduce the problem with, can you post:

1. The CREATE TABLE-Statement of the table (in the state before the change set runs)
2. The relevant part of your changelog/changeset

Re : How can I disable logging in tests?

Finally figured it out.

I had Logback on the classpath, so to disable it I had to set the log level in Logback instead of on the logger instance because the setLogLevel() method in Slf4jLogger no-ops.

I basically did before running my Liquibase test command.

val logger = LoggerFactory.getLogger("liquibase")
(logger as ch.qos.logback.classic.Logger).level = Level.ERROR

Thie issue appears to be that it is trying to access the files using an absolute path:

  1. file:/release1/ddl/001_SAMPLE.sql

rather than 

  1. file:/C:/some_path_to_project/release1/ddl/001_SAMPLE.sql

It isn't clear from the documentation, but looking at the code it looks like it might be possible to have an attribute 'relativeToChangelogFile' on that element.

Cannot use array on h2 with liquibase while in postgres works perfectly

In postgres the array is correctly created (i got INFO 07/05/18 19.07: liquibase: classpath:/db/changelog/db.changelog-master.xml: classpath:/db/changelog/db.changelog-master.xml::pg-101::marco_scarpa: Table SYM_NAMES created

In h2 i get such error:

It looks it adds randomly ARRAY[*] to the query and I don't know why.

It is not clear from your question what metadata you want to load, what you have tried, what your expected results were or what the actual results were. "I have tried and failed" just isn't descriptive enough.
