+This is our recommended way of referencing other objects. However, if you don't manage the referenced object in Terraform, you can construct the proper id yourself like before: `"\"database_name\".\"schema_name\".\"object_name\""` for schema-level objects, or `"\"database_name\".\"schema_name\".\"procedure_name(NUMBER, VARCHAR)\""` for procedures. Note that quotes are necessary for correct parsing of an identifier.
