Built-in ElasticGraph scalar types are automatically configured with appropriate warehouse column types. Custom scalar types must explicitly call warehouse_column to specify their warehouse type.

Returns the warehouse column type representation for this scalar type.

Returns:

  • (String) —

    the SQL type string (e.g., "INT", "DOUBLE", "BOOLEAN", "STRING")

Raises:

  • (RuntimeError) —

    if warehouse_column_type has not been configured
