atoti_directquery_mssql.MsSqlConnectionInfo

class atoti_directquery_mssql.MsSqlConnectionInfo

Information needed to connect to a Microsoft SQL Server database.

__init__(url, /, *, auto_multi_column_array_conversion=None, lookup_mode='warn', max_sub_queries=50, password=None, query_timeout=datetime.timedelta(seconds=3600))

Create a Microsoft SQL Server connection info.

Parameters:

• url (str) – The JDBC connection string. See https://learn.microsoft.com/en-us/sql/connect/jdbc/building-the-connection-url?view=sql-server-ver16 for more information.

• auto_multi_column_array_conversion (AutoMultiColumnArrayConversion | None) – When not None, multi column array conversion will be performed automatically.

• lookup_mode (Literal['allow', 'warn', 'deny']) – Whether lookup queries on the external database are allowed. Lookup can be very slow and expensive as the database may not enforce primary keys.

• max_sub_queries (int) – Maximum number of subqueries performed when splitting a query into multi-steps queries.

• password (str | None) –

  The password to connect to the database.

  Passing it in this separate parameter allows to avoid having it logged alongside the connection string.

  If None, a password is expected to be present in the passed url.

• query_timeout (timedelta) – Timeout for queries performed on the external database.
