SHOW ALERTS¶

Lists the alerts for which you have access privileges.

You can use this command to list objects in the current database and schema for the session, a specified database or schema, or your entire account.

The output includes the metadata and properties for each object. The objects are sorted lexicographically by database, schema, and object name (see Output in this topic for descriptions of the output columns). The order is important to note if you want to filter the results.

Tip

You can also use the Snowflake REST APIs to perform this operation. For information, see List alerts (REST endpoint reference).

Syntax¶

SHOW [ TERSE ] ALERTS [ LIKE '<pattern>' ]
                      [ IN
                            {
                              ACCOUNT                                         |

                              DATABASE                                        |
                              DATABASE <database_name>                        |

                              SCHEMA                                          |
                              SCHEMA <schema_name>                            |
                              <schema_name>

                              APPLICATION <application_name>                  |
                              APPLICATION PACKAGE <application_package_name>  |
                            }
                      ]
                      [ STARTS WITH '<name_string>' ]
                      [ LIMIT <rows> [ FROM '<name_string>' ] ]

Parameters¶

TERSE

Returns only a subset of the output columns:

created_on
name
kind (shows NULL for all alerts)
database_name
schema_name
schedule
state

LIKE 'pattern'

Optionally filters the command output by object name. The filter uses case-insensitive pattern matching, with support for SQL wildcard characters (% and _).

For example, the following patterns return the same results:

... LIKE '%testing%' ...

... LIKE '%TESTING%' ...

. Default: No value (no filtering is applied to the output).

[ IN ... ]

Optionally specifies the scope of the command. Specify one of the following:

ACCOUNT

Returns records for the entire account.

DATABASE, . DATABASE db_name

Returns records for the current database in use or for a specified database (db_name).

If you specify DATABASE without db_name and no database is in use, the keyword has no effect on the output.

SCHEMA, . SCHEMA schema_name, . schema_name

Returns records for the current schema in use or a specified schema (schema_name).

SCHEMA is optional if a database is in use or if you specify the fully qualified schema_name (for example, db.schema).

If no database is in use, specifying SCHEMA has no effect on the output.

APPLICATION application_name, . APPLICATION PACKAGE application_package_name: Returns records for the named Snowflake Native App or application package.

Default: Depends on whether the session currently has a database in use:

Database: DATABASE is the default (that is, the command returns the objects you have privileges to view in the database).
No database: ACCOUNT is the default (that is, the command returns the objects you have privileges to view in your account).

STARTS WITH 'name_string'

Optionally filters the command output based on the characters that appear at the beginning of the object name. The string must be enclosed in single quotes and is case-sensitive.

For example, the following strings return different results:

... STARTS WITH 'B' ...

... STARTS WITH 'b' ...

. Default: No value (no filtering is applied to the output)

LIMIT rows [ FROM 'name_string' ]

Optionally limits the maximum number of rows returned, while also enabling “pagination” of the results. The actual number of rows returned might be less than the specified limit. For example, the number of existing objects is less than the specified limit.

The optional FROM 'name_string' subclause effectively serves as a “cursor” for the results. This enables fetching the specified number of rows following the first row whose object name matches the specified string:

The string must be enclosed in single quotes and is case-sensitive.
The string does not have to include the full object name; partial names are supported.

Default: No value (no limit is applied to the output)

Note

For SHOW commands that support both the FROM 'name_string' and STARTS WITH 'name_string' clauses, you can combine both of these clauses in the same statement. However, both conditions must be met or they cancel out each other and no results are returned.

In addition, objects are returned in lexicographic order by name, so FROM 'name_string' only returns rows with a higher lexicographic value than the rows returned by STARTS WITH 'name_string'.

For example:

... STARTS WITH 'A' LIMIT ... FROM 'B' would return no results.
... STARTS WITH 'B' LIMIT ... FROM 'A' would return no results.
... STARTS WITH 'A' LIMIT ... FROM 'AB' would return results (if any rows match the input strings).

Output¶

The output of the command includes the following columns, which describe the properties and metadata of the object:

Column	Description
`created_on`	Date and time when the alert was created.
`name`	Name of the alert.
`database_name`	Database in which the alert is stored.
`schema_name`	Schema in which the alert is stored.
`owner`	Role that owns the alert (i.e. has the OWNERSHIP privilege on the alert)
`comment`	Comment for the alert.
`warehouse`	Warehouse that provides the required resources to run the alert.
`schedule`	Schedule for evaluating the condition for the alert.
`state`	Specifies the state of the alert. An alert can have one of the following states: `suspended` `started`
`condition`	The text of the SQL statement that serves as the condition when the alert should be triggered.
`action`	The text of the SQL statement that should be executed when the alert is triggered.
`owner_role_type`	The type of role that owns the object, for example `ROLE`. . If a Snowflake Native App owns the object, the value is `APPLICATION`. . Snowflake returns NULL if you delete the object because a deleted object does not have an owner role.

Access control requirements¶

A role used to execute this SQL command must have at least one of the following privileges at a minimum:

Privilege	Object	Notes
MONITOR, OPERATE, or OWNERSHIP	Alert	OWNERSHIP is a special privilege on an object that is automatically granted to the role that created the object, but can also be transferred using the GRANT OWNERSHIP command to a different role by the owning role (or any role with the MANAGE GRANTS privilege).

Note that operating on any object in a schema also requires the USAGE privilege on the parent database and schema.

For instructions on creating a custom role with a specified set of privileges, see Creating custom roles.

For general information about roles and privilege grants for performing SQL actions on securable objects, see Overview of Access Control.

Usage notes¶

Only returns rows for an alert owner (i.e. the role with the OWNERSHIP privilege on an alert) or a role with the OPERATE privilege on an alert.
The command does not require a running warehouse to execute.
The value for LIMIT rows cannot exceed 10000. If LIMIT rows is omitted, the command results in an error if the result set is larger than 10K rows.

To post-process the output of this command, you can use the RESULT_SCAN function, which treats the output as a table that can be queried.
