Example

import slick.migration.api._

val db = Database.forConfig("example-config")

implicit val dialect: H2Dialect = new H2Dialect

class MyTable(tag: Tag) extends Table[(Int, String)](tag, "my_table") {
  val col1 = column[Int]("col1")
  val col2 = column[String]("col2")
  val index1 = index("idx1", col1)
  def * = (col1, col2)
}
val MyTable = TableQuery[MyTable]
val init =
  TableMigration(MyTable)
    .create
    .addColumns(_.col1, _.col2)
    .addIndexes(_.index1)
    .renameColumn(_.col1, "col3")
val seed =

val migration = init & seed

db.run(migration())
