Hello

Using PB 2025 R2 build 6430, PostgreSQL 18.4 on x86_64-windows, compiled by msvc-19.44.35226, 64-bit, ADO.NET DB to connect Postgresql.  

My ADO.net connnection


My table structure [ From PG Admin ]

Datawindow [ Column specification ]   UUID datatype is referred as char(39)

So I give retrieval argument's datatype as string

And gave it in where clause

 

When I try to save the datawindow I get this error

1. Whether PB 2025 R2 supports Postgresql 18 or not?  Documentation says it is supported.   https://docs.appeon.com/pb/whats_new/Updated_system_requirements_2025r2.html

2.  Whether UUID datatype is supported or not?  UUID is available since version 15, afaik.  

I tried changing the datatype in Retrieval argument from string to number.  It saves, but when I try to retrieve the data in the IDE's datawindow, I get


How to resolve this issue?

Happiness Always
