This function was replaced with more general alternative on DSL layer. DAOs transform() is deprecated and will be removed in future releases. Please use the transform function from the DSL layer. Please log a request on YouTrack (https://youtrack.jetbrains.com/newIssue?project=EXPOSED) if a use-case cannot be sufficiently covered by the DSL transform(). With version 0.53.0 Entity transformation got several breaking changes. Check related PR (https://github.com/JetBrains/Exposed/pull/2143) for more details.
Replace with
object : Table() { val c = column().transform(transformer) }Returns a EntityFieldWithTransform delegate that transforms this stored Unwrapped value on every read.
Parameters
