Functions

func InitAdapterSelector

Types

type Adapter

type Adapter interface {
	ListTables() ([]string, error)

	// ListColumns returns a []string of column names for the given table
	// It MUST NOT return any columns which are foreign key columns. These will instead come from ListReferences
	ListColumns(table string) ([]string, error)

	// ListIndices returns a []string of index names for the given table.
	// It MUST NOT return information referring to PrimaryKey or Foreign Keys, which will instead come from GetColumn and
	// ListReferences respectively
	ListIndices(table string) ([]string, error)

	// ListReferences returns a []string of tables referenced from the given table.
	ListReferences(table string) ([]string, error)

	// GetColumn returns a schema.Column representing the given tableName and colName.
	GetColumn(table, column string) (schema.Column, error)

	// GetIndex returns a schema.Index representing the given tableName and indexName.
	GetIndex(table, column string) (schema.Index, error)

	// GetReference returns a schema.Reference representing the given tableName and indexName.
	GetReference(table, column string) (schema.Reference, error)
}

Adapter is the yoyo interface for reverse-engineering databases to a schema.Database for creating diff migrations and for creating a yoyo.yml from an existing database.
