CreateTableNoCompressAdvanced
Last updated: January 30, 2026
CreateTableNoCompressAdvance is a custom policy check that prevents the use of COMPRESS FOR in CREATE TABLE statements and only allows compress or compress basic statements.
regex: (?is)(?=.*\b(create)\b)(?=.*\b(table)\b)(?=.*\b(compress)\b)(?=.*\b(advanced)\b).*
This example utilizes Oracle. You can use this check as it is or customize it further to fit your needs in your SQL database. All Regex Custom Policy Checks can only run against the changelog, not against the database.

Liquibase 4.29.0+
Configure a valid Liquibase Pro license key
Ensure the Liquibase Checks extension is installed. In Liquibase 4.31.0+, it is already installed in the
/liquibase/internal/libdirectory, so no action is needed.If the checks JAR is not installed, download
liquibase-checks-<version>.jarand put it in theliquibase/libdirectory.Maven users only:
Add this dependency to your pom.xml file:
<dependency>
<groupId>org.liquibase.ext</groupId>

Procedure
These steps describe how to create the Custom Policy Check. It does not exist by default in Liquibase Pro.
Run this command in the CLI:
liquibase checks customize --check-name=SqlUserDefinedPatternCheckGive your check a short name for easy identification
Use up to 64 alpha-numeric characters only.
In this example we will use:
CreateTableNoCompressAdvancedSet the Severity to return a code of 0-4 when triggered.
These severity codes allow you to determine if the job moves forward or stops when this check triggers.
Learn more here: Use Policy Checks in Automation: Severity and Exit Code
options: 'INFO'=0, 'MINOR'=1, 'MAJOR'=2, 'CRITICAL'=3, 'BLOCKER'=4
Set the SEARCH_STRING to this valid regular expression:
Regular expression search string
((?is)(?=.*\b(create)\b)(?=.*\b(table)\b)(?=.*\b(compress)\b)(?=.*\b(advanced)\b).*Set the MESSAGE to display when a match for the regular expression <SEARCH_STRING> is found in a Changeset.
In this example we will use:
Error! COMPRESS ADVANCED is not allowed in a CREATE TABLE statement.Set STRIP_COMMENTS to true if you want to remove the comments from the output.
Results
The regex custom policy check is created successfully.
