Procedure

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

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.

CreateTableMustHavePrimaryKey
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
(?is)(?=.*\b(create)\b)(?=.*\b(table)\b)(?!.*\b(primary)\b)(?!.*\b(key)\b).*
5

Set the MESSAGE to display when a match for the regular expression <SEARCH_STRING> is found in a Changeset.

Error! CREATE TABLE statement must have a primary key included.

6

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

The regex custom policy check is created successfully.
