Thanks

Hi,

Please reply me if anyone have idea on this.

Well... I don't know expression type that can describe custom SQL directly.

But, there is a feature called NativeQuery to achieve similar things with your expression.
https://www.activiti.org/userguide/#queryAPI

${execution.getEngineServices().getRuntimeService().createNativeExecutionQuery().sql('UPDATE act_custom_process SET status=#{status} WHERE id=#{id}').parameter('status', 'true').parameter('id', '44').singleResult()}

SQL Process.bpmn.zip

Thank you for your reply. This is helpful in future. But I would like to execute the query in bpmn file. do you know about that?

vamsinipun

Please let me know how can i execute this means where can i place it?

${execution.getEngineServices().getRuntimeService().createNativeExecutionQuery().sql('UPDATE act_custom_process SET status=#{status} WHERE id=#{id}').parameter('status', 'true').parameter('id', '44').singleResult()}

It is the same as the image you are up and can be entered directly in the Expression column.

The sample process definition is as follows.

Ya. I put like that only, but it is not executed. do you know any reason for that means any configuration or mappings?

unknown

Please share your bpmn file.

Please check above xml file.

Finally i executed with static query with given below expression by you

Now, how can i pass dynamic fields instead of static values like 'true' and 44?

unknown

You can use variables to pass dynamic fields as the following expression.

${execution.getEngineServices().getRuntimeService().createNativeExecutionQuery().sql('UPDATE act_custom_process SET status=#{status} WHERE id=#{id}').parameter('status', execution.getVariable('flag')).parameter('id', execution.getVariable('id')).singleResult()}

By the way, what was the cause for not working first?

vamsinipun

Thank you for your reply once again. almost i reached my requirement. please help me in this too.

Here we have assignee option with variable like ${reporting_manager}. I was set the value through my java code, instead of that how can i set that through sql without java?

unknown

You can set variable by the el expression as the following expression.

Activiti User Guide

${execution.setVariable('reporting_manager', %Value%)}

vamsinipun

Hi,

if i execute the query in java class mean listener. how can i get those data?

unknown

It is not possible to select from any table.

If it is an Activiti table, you can do it.

vamsinipun

k now how can i get the application table data? is there any other way?
