Methods

  • This method is called when AbstractQueryGenerator needs to add a bind parameter to a query it is building. This method allows for customizing both the SQL to add to the query, and convert the bind parameter value to a DB-compatible value.

    If you only need to prepare the bind param value, implement toBindableValue instead.

    This method must return the SQL to add to the query. You can obtain a bind parameter ID by calling BindParamOptions#bindParam with the value associated to that bind parameter.

    An example of a data type that requires customizing the SQL is the GEOMETRY data type.

    Parameters

    Returns string

  • Called when a value is retrieved from the Database, and its DataType is specified. Used to normalize values from the database.

    Note: It is also possible to do an initial parsing of a Database value using AbstractDialect#registerDataTypeParser. That normalization uses the type ID from the database instead of a Sequelize Data Type to determine which parser to use, and is called before this method.

    Parameters

    • value: unknown

      The value to parse.

    Returns unknown

  • Converts a JS value to a value compatible with the connector library for this Data Type. Unlike escape, this value does not need to be escaped. It is passed separately to the database, which will handle escaping.

    Parameters

    Returns unknown
