hello, i'm looking for tutorial how to use multiple database in one prisma?

Hmm, curious why you would try to do this? Why not setup multiple instances of Prisma and handle sending data to each instance through your GraphQL server?

i new on prisma, so i think it can be join data from another database on one prisma instance. like, i can get from structural DB and unstructural DB

www.howtographql.com might have some answers 🙂

wow, thanks.

Interesting, I don’t think Prisma will join multiple databases into one Prisma instance. However, I’m curious to hear what you find out!

Prisma currently doesn't support multiple database behind the same GraphQL API - but this is a super exciting research topic for us, and we've already started to investigate into that direction. Here is a relevant discussion/feature request: https://github.com/prismagraphql/prisma/issues/2873

now, i have multi instance prisma, and join on application layer, but my project is logging data from multi database. i know this is wrong architecture 😣(my application architecture). but prisma solve my complex data structure. so i think how to connect database on one prisma instance.

Got it - it would be awesome if you share a description about your current approach, its shortcomings and how you envision this to work in the future in the feature request I shared above 🙂 this will allow us to take your situation into account once we start building multi-db support

i have hundreds cargo ship. and many warehouse. for this case. - tracking of cargo ship times and coordinates, history and at least 4 days destination - tracking items out from cargo and store to warehouse (what item, who is the carrier, etc) - join their item with client order. so i think on these case, i try to join prisma on multi DB, for get data on structural DB and unstructural DB. from structural i get user info from unstructural i get item logging information
