DbUp supports basic variable substitution, to enable you should register variables when configuring DbUp:
DeployChanges.To .SqlDatabase(..) .WithVariable("TestVariable", "Value")
Then in your database script:
-- $TestVariable$ $AnotherVariable$ print '$TestVariable$' SELECT * FROM dbo.$TestVariable
-- Value $AnotherVariable$ print 'Value' SELECT * FROM dbo.Value
Variables can only contain letters, digits,
-. If there are any other characters between the
$s it is not treated as a variable. If a variable is found within a script, but not supplied an exception will be thrown unless it is within a comment.
Note: there is no way to escape variables, if this causes you issues, create a GitHub issue or submit a pull request to allow escaping!
