Assuming you have an SQL file (or string) you want to run as part of the migration, which has a number of statements...
CI migration only allows you to run one statement at a time. If the SQL is generated, it's annoying to split it up and create separate statements.
This small script splits the statements allowing you to run them all in one go.
