create(alert: str, *, clone_alert: str | Clone, mode: CreateMode = CreateMode.error_if_exists) → AlertResource¶

create(alert: Alert, *, clone_alert: None, mode: CreateMode = CreateMode.error_if_exists) → AlertResource

Create an alert in Snowflake.

There are two ways to create an alert: by cloning or by building from scratch.

Cloning an existing alert

Parameters:

• alert (str) – The new alert’s name

• clone_alert (str or Clone object) – The name of alert to be cloned

• mode (CreateMode, optional) –

  One of the following enum values:

  CreateMode.error_if_exists: Throw an snowflake.core.exceptions.ConflictError if the alert already exists in Snowflake. Equivalent to SQL create alert <name> ....

  CreateMode.or_replace: Replace if the alert already exists in Snowflake. Equivalent to SQL create or replace alert <name> ....

  CreateMode.if_not_exists: Do nothing if the alert already exists in Snowflake. Equivalent to SQL create alert <name> if not exists...

  Default is CreateMode.error_if_exists.

Examples

Cloning an alert instance:

>>> alerts = schema.alerts
>>> alerts.create(
...     new_alert_name,
...     clone_alert=alert_name_to_be_cloned,
...     mode=CreateMode.if_not_exists,
... )

Copy

Creating an alert from scratch

Parameters:

• alert (Alert) – The details of Alert object, together with Alert’s properties: name, schedule, condition, action ; comment, warehouse are optional.

• mode (CreateMode, optional) –

  One of the following enum values:

  CreateMode.error_if_exists: Throw an snowflake.core.exceptions.ConflictError if the alert already exists in Snowflake. Equivalent to SQL create alert <name> ....

  CreateMode.or_replace: Replace if the alert already exists in Snowflake. Equivalent to SQL create or replace alert <name> ....

  CreateMode.if_not_exists: Do nothing if the alert already exists in Snowflake. Equivalent to SQL create alert <name> if not exists...

  Default is CreateMode.error_if_exists.

Examples

Creating an alert instance:

>>> alerts.create(
...     Alert(
...         name="my_alert",
...         warehouse="my_warehouse",
...         schedule="MinutesSchedule(minutes=1)",
...         condition="SELECT COUNT(*) FROM my_table > 100",
...         action="DROP TABLE my_table",
...     ),
...     mode=CreateMode.if_not_exists,
... )

Copy

items() → ItemsView[str, T]¶

iter(*, like: Annotated[str, Strict(strict=True)] | None = None, starts_with: Annotated[str, Strict(strict=True)] | None = None, show_limit: Annotated[int, FieldInfo(annotation=NoneType, required=True, metadata=[Strict(strict=True), Ge(ge=1), Le(le=10000)])] | None = None, from_name: Annotated[str, Strict(strict=True)] | None = None) → Iterator[Alert]¶

Iterate through Alert objects from Snowflake, filtering on any optional ‘like’ pattern.

Parameters:

• like (str, optional) – A case-insensitive string functioning as a filter, with support for SQL wildcard characters (% and _).

• starts_with (str, optional) – String used to filter the command output based on the string of characters that appear at the beginning of the object name. Uses case-sensitive pattern matching.

• show_limit (int, optional) – Limit of the maximum number of rows returned by iter(). The default is None, which behaves equivalently to show_limit=10000. This value must be between 1 and 10000.

• from_name (str, optional) – Fetch rows only following the first row whose object name matches the specified string. This is case-sensitive and does not have to be the full name.

Examples

Showing all alerts that you have access to see:

>>> alerts = alert_collection.iter()

Copy

Showing information of the exact alert you want to see:

>>> alerts = alert_collection.iter(like="your-alert-name")

Copy

Showing alerts starting with ‘your-alert-name-‘:

>>> alerts = alert_collection.iter(like="your-alert-name-%")

Copy

Using a for loop to retrieve information from iterator:

>>> for alert in alerts:
>>>     print(alert.name, alert.condition, alert.action)
