## Task Parameters
-| **Parameter** | **Description** |
-| ------- | ---------- |
-| Node Name | Set the name of the task. Node names within a workflow
definition are unique. |
-| Run flag | Indicates whether the node can be scheduled normally. If it is
not necessary to execute, you can turn on the prohibiting execution switch. |
-| Description | Describes the function of this node. |
-| Task priority | When the number of worker threads is insufficient, they are
executed in order from high to low according to the priority, and they are
executed according to the first-in, first-out principle when the priority is
the same. |
-| Worker group | The task is assigned to the machines in the worker group for
execution. If Default is selected, a worker machine will be randomly selected
for execution. |
-| Task group name | The group in Resources, if not configured, it will not be
used. |
-| Environment Name | Configure the environment in which to run the script. |
-| Number of failed retries | The number of times the task is resubmitted after
failure. It supports drop-down and manual filling. |
-| Failure Retry Interval | The time interval for resubmitting the task if the
task fails. It supports drop-down and manual filling. |
-| Timeout alarm | Check Timeout Alarm and Timeout Failure. When the task
exceeds the "timeout duration", an alarm email will be sent and the task
execution will fail. |
-| DataSource | The DataSource type of the stored procedure supports MySQL and
POSTGRESQL, select the corresponding DataSource. |
-| Method | The method name of the stored procedure. |
-| Custom parameters | The custom parameter types of the stored procedure
support `IN` and `OUT`, and the data types support: VARCHAR, INTEGER, LONG,
FLOAT, DOUBLE, DATE, TIME, TIMESTAMP and BOOLEAN. |
-| Predecessor task | Selecting the predecessor task of the current task will
set the selected predecessor task as the upstream of the current task. |

+ ```
+ CREATE PROCEDURE dolphinscheduler.test(in in1 INT, out out1 INT)
+ begin
+ set out1=in1;
+ END
