Unable to read <null> decimal with SQLite

See original GitHub issue

Bug description

Having the following field in a SQLite database:

scheduled_distance NUMERIC (6, 3)

and in schema.prisma:

scheduledDistance Decimal?   @map("scheduled_distance")

will give:

Invalid `prisma.race.findMany()` invocation:\n\n\n  
Inconsistent column data: Conversion failed: Value NUMERIC(6,3) not supported

in case a record contains a null value for this column.

So e.g. value 806.982, 806 works, but null gives the above error. Note I mean actual null not a "null" string.

As it is an optional column null should be possible.

How to reproduce

See bug description.

Expected behavior

Rows with e.g. null to be read successfully.

@janpio good point indeed… I introspected with older version some time ago. So probably good to see if latest version is doing that as well.

But if the database is scheduled_distance NUMERIC (6, 3), which is not actually valid for SQL from what you wrote, why should it introspect this as Decimal?? Wouldn’t it be better to not introspect that field then?
