History ======= * v0.82 First official build of the contrib project. Depends on DNM 0.82. Adds the PersistentMigrations and TextLog plugins. PersistentMigrations plugin =========================== * Specify folders that contain migration scripts that should be run everytime the schema is migrated. (persistentMigrateFolders app setting) * Everytime a migrate command is run, all persistent migration scripts are run in a separate transaction. * Run the 'pmigrate' command directly to execute only the persistent migration scripts. * Persistent migrations work great for functions, stored procedures and even views. Because persistent migration scripts allow you to keep the full history of an object in a single file (rather than each change to the object being in a separate file), you can leverage your source contorl's diff and history features to manage those object scripts just like you would other source code. * Use the ##DNM:VERSION## token in your persistent migration scripts to decide which part of the script should run. Here is an example script that drops a table if it already exists and only recreates it if the database version is greater than 0. IF EXISTS(SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 'People') BEGIN DROP TABLE [People] END IF ##DNM:VERSION## > 0 BEGIN CREATE TABLE [People] ([Name] varchar(100)) END TextLog plugin ============== * Output program information to a text file instead of to the console (STDOUT).
