Answer 1

You can do this by calling the Hibernate Session.createSQLQuery() method. First you need to get the Hibernate session then use that session to execute SQL. See this link to see how to get a Hibernate session from your grails app. Then see this link for info on using Hibernate to execute SQL.

Answer 2

groovy.sql.Sql simplifies the details of doing JDBC queries. In a Grails app you'd use the constructor that takes a DataSource:

import groovy.sql.Sql
...
class FooService {

   def dataSource
   ...
   def runSqlQuery(...) {
      Sql sql = new Sql(dataSource)
      sql.executeInsert("insert into ...")
      ...
   }
}
