Welcome to elephant_parsel’s documentation!

PostgresDB

class elephant_parsel.postgres_db.PostgresDB(connection_config: dict, logger: Logger, connect=True, register_hstore=False)

censored_config()

execute(statement: str, arguments=None, use_transaction: bool = True)

execute_values(statement: str, arguments: list, template: Optional[str] = None, map_row=None, column: Optional[str] = None)

Like query_all, but with a list of arguments: statement must contain a single %s placeholder. args must be a list of sequences or mappings. template can be a string with placeholders, which will be used for each item. see https://www.psycopg.org/docs/extras.html#psycopg2.extras.execute_values
