CreateTableWithCertainColumnRequiresSequence
CreateTableWithCertainColumnRequiresSequence is a custom policy check that requires when a CREATE TABLE statement with a certain column such as SQLKEY exists, there must also be a CREATE SEQUENCE included.
regex: (?is)(?=.*\b(create.*table.*sqlkey\s+number)\b)(?!.*\b(create\s+sequence)\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.

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:
Give your check a short name for easy identification
Use up to 64 alpha-numeric characters only.
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.

options: 'INFO'=0, 'MINOR'=1, 'MAJOR'=2, 'CRITICAL'=3, 'BLOCKER'=4
Set the SEARCH_STRING to this valid regular expression:
Regular expression search string
Set the MESSAGE to display when a match for the regular expression <SEARCH_STRING> is found in a Changeset.
Set STRIP_COMMENTS to true if you want to remove the comments from the output.
CreateTableMustHaveOneGrant
Leave the PATH_Filter_REGEX blank.
Set SPLIT_STATEMENTS to false.
Settting SPLIT_STATEMENTS to false prevents Liquibase from splitting multiple SQL statements on the delimiter or evaluating each individually.
