DESCRIBE TASK¶
Shows information about a task.
DESCRIBE can be abbreviated to DESC.
- See also:
Syntax¶
DESC[RIBE] TASK <name>
Parameters¶
nameSpecifies the identifier for the task to describe. If the identifier contains spaces or special characters, the entire string must be enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive.
Output¶
The command provides the same output as SHOW_TASKS.
Usage notes¶
Only returns rows for a task owner—that is, the role with the OWNERSHIP privilege on a task—or a role with either the MONITOR or OPERATE privilege on a task.
To post-process the output of this command, you can use the pipe operator (
->>) or the RESULT_SCAN function. Both constructs treat the output as a result set that you can query.For example, you can use the pipe operator or RESULT_SCAN function to select specific columns from the SHOW command output or filter the rows.
When you refer to the output columns, use double-quoted identifiers for the column names. For example, to select the output column
type, specifySELECT "type".You must use double-quoted identifiers because the output column names for SHOW commands are in lowercase. The double quotes ensure that the column names in the SELECT list or WHERE clause match the column names in the SHOW command output that was scanned.
Examples¶
Create an example task:
CREATE TASK mytask ( ... );
Show information about the task:
DESC TASK mytask;
For output examples, see SHOW_TASKS.
