ExecuteImmediateWarning
ExecuteImmediateWarning is a custom policy check that warns you if any EXECUTE IMMEDIATE statements are detected.
regex: [\t\n\r\s]*(?i:execute)[\t\n\r\s]*(?i:immediate\s)
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/lib
directory, so no action is needed.If the checks JAR is not installed, download
liquibase-checks-<version>.jar
and put it in theliquibase/lib
directory.Maven users only:
Add this dependency to your pom.xml
file:

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.
CreateTableWithCertainColumnRequiresTrigger
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
(?is)(?=.*\b(create.*table.*sqlkey\s+number)\b)(?!.*\b(create./trigger)\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! SQLKEY column requires creation of a TRIGGER. Ensure that you have a CREATE OR REPLACE TRIGGER in your 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.
