Syntax

mysql> SELECT mysql_tasks.task_list(
  IN 'task_type' VARCHAR(80), 
  IN offset INT UNSIGNED, 
  IN limit INT UNSIGNED);

Following are task_list parameters:

• task_type (VARCHAR(80)): filters the tasks based on a specific task type. If the value is NULL, tasks of all types are included. Task type for tasks created using the execute_prepared_stmt_async procedure is Async_SQL. For asynchronous VECTOR_STORE_LOAD tasks, the task type is GenAI_Load.

• offset (INT UNSIGNED): the number of rows to skip. The offset value is used for pagination. If the value is NULL, the offset defaults to 0, and the result is displayed starting from the first row.

• limit (INT UNSIGNED): the maximum number of task records included in the list of tasks. If the value is NULL, the limit defaults to 20, and up to 20 rows are displayed.

Syntax Example

mysql> JSON_PRETTY(mysql_tasks.task_list('Async_SQL', 2, 2));

The output is similar to the following:

| [
  {
    "id": "4605cf38-527b-11f0-bca4-020017205654",
    "data": {
      "mysqlMetadata": {
        "autoGc": true,
        "events": [
          "`demo_db`.`4605c15a-527b-11f0-bca4-020017205654`"
        ]
      }
    },
    "name": "DemoAsyncTask",
    "task_type": "Async_SQL",
    "connection_id": 63582
  },
  {
    "id": "18398c40-527b-11f0-bca4-020017205654",
    "data": {
      "mysqlMetadata": {
        "autoGc": true,
        "events": [
          "`demo_db`.`18397be6-527b-11f0-bca4-020017205654`"
        ]
      }
    },
    "name": "DemoAsyncTask",
    "task_type": "Async_SQL",
    "connection_id": 63576
  }
] |

This example lists two tasks of type Async_SQL.
