Some developers have added empty
dbgenerated()attributes to their schema to support GENERATED columns in postgres. See prisma/prisma#20077Prior to the changes in tjis PR,
drizzle-prisma-generatorwill throw an error whendbgenerated()is empty.The error message is largely unhelpful, because there isn't an easy way to get the stack-trace from the prisma cli. However by examining the code you can see that the dbgenerated handling expects there always to be an argument for this attribute.
This change allows for empty dbgenerated attributes (no arg), and declares them as GENERATED columns. We use a dummy SQL for the generated expression, since we have no way of knowing the actual expression or value the developer actually used.
