ColumnType column type implements ColumnType interface
      
func (ct ColumnType) DatabaseTypeName() string
  
DatabaseTypeName returns the database system name of the column type. If an empty
string is returned, then the driver type name is not supported.
Consult your driver documentation for a list of driver data types. Length specifiers
are not included.
Common type names include "VARCHAR", "TEXT", "NVARCHAR", "DECIMAL", "BOOL",
"INT", and "BIGINT".

func (m Migrator) GuessConstraintAndTable(stmt *gorm.Statement, name string) (*schema.Constraint, *schema.CheckConstraint, string)
  
GuessConstraintAndTable guess statement's constraint and it's table based on name
Deprecated: use GuessConstraintInterfaceAndTable instead.
      
func (m Migrator) GuessConstraintInterfaceAndTable(stmt *gorm.Statement, name string) (_ schema.ConstraintInterface, table string)
  
GuessConstraintInterfaceAndTable guess statement's constraint and it's table based on name
