詳細
Description

GORM does not provide a deleteAll method as deleting data must be done with caution. To delete data you can use executeUpdate. The basic syntax is:

Book.executeUpdate(String query)
Book.executeUpdate(String query, List positionalParams)
Book.executeUpdate(String query, Map namedParams)

パラメータ:

Parameters:
  • query - An HQL query with DML-style operations
  • positionalParams - A List of parameters for a positional parameterized HQL query
  • namedParams - A Map of parameters for a named parameterized HQL query
