Hello I am using Moose 6.0 (Pharo 5.0 Latest update: #50761) on Windows 10. I have installed PunQLite following the instructions in https://github.com/mumez/PunQLite. I have run all the examples that involve using files, and everything seems OK. I have tried creating a database using my own data, which seemed to run OK. The database will display its keys successfully, but whenever I try to retrieve a value I get PqFetchError. The debug information shows that an ffi fetch operation has given a return value of -10. I have searched for any information on unQLite return codes, but so far I have nothing. I tried the PqDatabaseBrowser in the Tools section. This recognised the database, opened it and displayed all the keys correctly. However, clicking on any key gave the same PqFetchError. Does anyone have any idea of what I have done wrong? Thanks for any help. Peter Kenny
