how to use query input for QueryPropertyHistory of a kepware tag?

[svisveswaraiya]

Hi,

Is it possible to use the input parameter Query in a service and pass this query input to filter the values in QueryPropertyHistory of a kepware tag?

For eg: I wanted to get only values that are greater than 10 in the QueryPropertyHistory of a tag. How can I filter this? If it is possible to use the query input parameter how should I define it?

Please provide some idea.

Thanks,

Shalini V.

My favorite reference when creating Queries: http://support.ptc.com/help/thingworx_hc/thingworx_8_hc/en/#page/ThingWorx%2FHelp%2FComposer%2FThings%2FThingServices%2FQueryParameterforQueryServices.html

All services that support the Query Input Parameter need it defined as a JSON.

This link should help with that.

Also the DataFilter Widget creates a JSON that can be directly used as a Query input parameter.
