How to use fragments inside sql queries?

[pleerock]

Thank you for your wonderful extension!

As I understand fragments are supposed to be parts of sql queries, they are useless otherwise. But how to include them inside sql queries?

const photoJoin = sqlFragment`
    INNER JOIN "photos" "photo" ON "photo"."authorId" = "user"."id"
`
const usersSql = sql`
SELECT * FROM "users" "user" ${photoJoin} WHERE userId=${userId}
`

But using this fragment leads to Failed to parse: syntax error at or near "$1". error. Did I miss something? Thanks!
