Resolved Problem with DataStore in WebService in PB2021

Hi All,

we are migrating to PB2021 our WebServices that we developed with PB2017 R3 and we are facing the following problem:

all the lds_DataStore.Retrieve() calls return -1 in PB2021. If we try to get the SQL statement of the DataObject with lds_DataStore.Describe("datawindow.table.select") the return value is a string of apparently randm characters and not the real SQL statement.

It seems that the SQL part of the DataObject is lost or modified.

Did someone have the same problem? Can anyone suggest a solution?

Thank you in advance for your replies.

Hi Antonio;

  In a PS 2021 deployed application, the real SQL in the client has been morphed into PS web services. It's now the PS WS that runs the real SQL and the client DW/DS objects are just left with Restful Web API calls.

Regards.. Chris

Hi Chris,

thank you for your reply.

Actually, we are using PowerBuilder and not PowerServer. We deploy our WebService using the MSI file that the .NET WebService Target generates.

The DW syntax is modified in the following way: retrieve="cloud;MTYzNDc2MzMzMA==;uLQgX4swwIkYIwm0mRYMpk9f8D7WoLAyOjocX67cWldoGWsombadlVFBF/fEQmOAzWIaaqFGhOEvqtNmy8eCG++koJXXcIFG8UuqZg7wRluRAkT42F4joTT1Uzwl7B94NhX5twTaSNOcguklR1/dBafkLml1gC78+5mi9WVOCRw=" 

I guess if there is a way to avoid the SQL statement of the DW to be modified.

Thank you

 

Antonio

Q: I guess if there is a way to avoid the SQL statement of the DW to be modified.

A: No, PowerScript always has full control.
