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=SqlUserDefinedPatternCheck
Give your check a short name for easy identification
Use up to 64 alpha-numeric characters only.
In this example we will use:
MultipleCreateTablesNotAllowed
Give your check a short name for easy identification
Use up to 64 alpha-numeric characters only.
Title the check:
MultipleCreateProceduresNotAllowed
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.

Set the SEARCH_STRING to this valid regular expression:
(?is)[\t\r\n\s]*\bcreate\b[\t\r\n\s]+\btable\b[\t\r\n\s]+.*[\t\r\n\s]+\bcreate\b[\t\r\n\s]+\btable\b[\t\r\n\s]+
Set STRIP_COMMENTS to true if you want to remove the comments from the output.
Set the MESSAGE for when a match for regular expression <SEARCH_STRING> is found in a Changeset:
In this example we will use:
Error! Multiple CREATE TABLE statements not allowed in a single changeset. Only a single CREATE TABLE statement is allowed.
