NoGrantsToPublic

NoGrantsToPublic is a custom policy check that prevents the use of GRANT <Privilege Type> TO PUBLIC statements.

regex: (?i:grant)[\t\n\r\s\S]*(?i:to public)

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.

Add this dependency to your pom.xml file: <dependency> <groupId>org.liquibase.ext</groupId> <artifactId>liquibase-checks</artifactId> <version>2.0.0</version> </dependency>

  • Java Development Kit 17+ (available for Open JDK and Oracle JDK)

  • Linux, macOS, or Windows operating system

Procedure

These steps describe how to create the Custom Policy Check. It does not exist by default in Liquibase Pro.

1

Run this command in the CLI:

liquibase checks customize --check-name=SqlUserDefinedPatternCheck
2

Give your check a short name for easy identification

Use up to 64 alpha-numeric characters only.

NoGrantsToSystem
3

Set 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

4

Set the SEARCH_STRING to this valid regular expression:

Regular expression search string
(?i:grant)[\t\n\r\s\S]*(?i:to public)
6

Set STRIP_COMMENTS to true if you want to remove the comments from the output.

5

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! GRANT to PUBLIC not allowed.
