When using quill in metals / vscode, metals - quill query compilation to SQL shows up as a "problem" in the compiler window
is this intentional?

Hello, im using application joins (ver 2.5.4).
Somehow outer select does not contain all columns of table but inner select (in join statements) does and as a result i get "column ... does no exist".

Is there a way to force select all columns from big applicative join with filters?

Zulek
@Zulek
or joins have columns that are not in a scope of particular join (...) statement
Alexander Ioffe
@deusaquilus
@Zulek There were various bugs with older versions of Quill with columns being excluded. Are these columns used in Group By (or other aggregations) but any chance?

@all Is anyone using AnyVal encoders? Are your AnyVal instances also case classes or not? In Dotty-Quill they might need to be.

Hi, if I have two value types which have the same underlying type (String), is there any way to perform "column update" (assign the value from one of the columns to the other)?

case class Email(email: String) extends AnyVal
case class EmailVerified(emailVerified: String) extends AnyVal

...
... .update(table => table.emailVerified -> table.email, ...

beside infix

Hello, how to compile list updating.
dynamicQuery[TestEntity].update(set("i", 1), set("l", 2L)) 
// compile error
dynamicQuery[TestEntity].update(list.map(a => set(a._1, a._2):_*))

@deusaquilus
@lachezar This is basically an update-with-join use case which unfortunately we don't support yet.

How to do select by a collection of compound keys? I have something like a runtime Vector[((UUID, Int), (UUID, Int))] and need to match on 4 corresponding columns. Using jdbc-monix and postgres.
attempt to liftQuery that vector would fail with "Can't tokenize a non-scalar lifting"

I'm trying to use a model that has a java.time.Instant field. I've put this in my context class:

        implicit val encodeInstant = MappedEncoding[Instant, LocalDateTime](i => LocalDateTime.ofInstant(i, ZoneOffset.UTC))
        implicit val decodeInstant = MappedEncoding[LocalDateTime, Instant](_.toInstant(ZoneOffset.UTC))

but I'm still getting the "Can't find implicit Decoder[java.time.Instant]" error

I've also tried putting it after my import ctx._

Hi guys, in quill 3.7.0 for whatever reason, the generated sql queries are not displayed at compile time anymore. Do you have the same problem? (I don't have -Dquill.macro.log=false in my build definition)

@nafg
Are there any sample projects besides quill-example and play-quill-jdbc repos? How do you maintain sample projects? (In Slick there's a lot of code in the SBT build dealing with it, which I'd like to simplify or eliminate, and I'm trying to find out what other people do.) Do you automate keeping them up to date, and if so, how? /cc @deusaquilus

I am getting a macro TypecheckException for no implicit Decoder when using H2ZioJdbcContext. What is it generally indicative of?
[error] scala.reflect.macros.TypecheckException: Can't find implicit `Decoder[Foo]`. Please, do one of the following things:
[error] 1. ensure that implicit `Decoder[Foo]` is provided and there are no other conflicting implicits;

It seems to be about invalid usage of nesting of case classes, which makes sense that I'd need Decoder or Encoder for nesting case classes.
so the type parameter T in EntityQuery[T] has nested case classes.
Philippe Derome
@phderome
looks like the doc tells me what I should be doing: https://getquill.io/#quotation-schema-embedded-case-classes
that was it.

hello. Can i use pattern matching on DynamicQuery. Like this:
schemaOne.dynamic.join(schemaTwo).on(_.id == _.id).groupBy  { case  quoted =>  // i want case (schema1, schema2) here
...
}

@n0tel

How can i use dynamic query with implicit joins?

// Implicit Joins:
quote {
  for {
    a <- query[A]
    b <- query[B] if (a.id == b.fk) 
  } yield (a, b)
}

if i use dynamic query, this code return DynamicQuery[Quoted[Schema1], Quoted[Schema2]]:

// Implicit Joins:
val dynamicQ = quote {
  for {
    a <- query[A].dynamic
    b <- query[B].dynamic if (a.id == b.fk) 
  } yield (a, b)
}

and if i then use groupBy, im getting error The query definition must happen within aquoteblock. [error] b.groupBy(_._1)

dynamicQ.groupBy(_._1)

Hi, can I somehow force quill to execute exactly the same sql I specified via infix?
When I execute this code

case class NamedEntity(name: String)
val rawQuery = s"SHOW DATABASES STARTS WITH '$dbName'"
run(quote(infix"#$rawQuery".as[Query[NamedEntity]])).exists(_.name == dbName)

I see query

SELECT "x"."name" FROM (SHOW DATABASES STARTS WITH 'ACC_***_DB') AS "x"

and get an error

SQL compilation error:
syntax error line 1 at position 24 unexpected 'SHOW'.

Hi everyone. I am trying to make join of count, but i getting stuck with Tuple(Quoted, Quoted). Is there any way to make it Quoted(Tuple(...))?

stream(
      for {
        item <- items.dynamic
                  .filter(_.id == lift(id))
                  .filter(_.parent.isEmpty)

        childsCount = items.dynamic
                  .filter(_.parent == lift(Some(item.id)))
                  .size

      } yield (item, childsCount)
    ).transact(transactor)

The output type is Stream[F, (Quoted[Item], Quoted[Long])], but it should be Stream[F, (Item, Long)]

Denis Novac
@DenisNovac
I guess i just don't really need dynamic call here. It works without it.

Hello

I'm trying to write a generic code with Quill to perform some operation on multiple datatype, as described in https://stackoverflow.com/questions/44784310/how-to-write-generic-function-with-scala-quill-io-library/44797199#44797199

I've created my macro

class FindMacro(val c: MacroContext) {
  import c.universe._

  def find[T](filter: Tree)(implicit t: WeakTypeTag[T]): Tree =
    q"""
            import ${c.prefix}._
            run(${c.prefix}.query[$t].filter($filter))
          """
}

That I'm then using in my generic trait:

trait Indexed[I, T] {
  def find(key: I, obj: T): Boolean
}

trait Storage[I, T] {
  def get(idx: I)(implicit eq: Indexed[I, T]): Task[Option[T]]
}

trait Queries { this: ZioJdbcContext[_, _] =>
  def find[T](filter: T => Boolean): T = macro FindMacro.find[T]
}

case class SqliteStorage[I, T](connection: Connection)(implicit schema: SchemaMeta[T]) extends Storage[I, T] {

  val ctx = new SqliteZioJdbcContext(SnakeCase) with Queries

  override def get(idx: I)(implicit eq: Indexed[I, T]): Task[Option[T]] =
    ctx.find[T](p => eq.find(idx, p))

}

Unfortunately, the implicit SchemaMeta[T] does not seems to work, I think I must be missing something here, but I don't understand what, could someone help me with that ?

Hello. What is the "right" way to deal with querying multiple databases in the same process? Create one context per database? I'm using quill-jasync-mysql in case that is relevant.
Lyall Jonathan Di Trapani
@lj-ditrapani
Oh, and this would be multiple logical databases on the same mysql instance (so could use same connection).
Lyall Jonathan Di Trapani
@lj-ditrapani
Looks like I can use https://getquill.io/#extending-quill-infix to dynamically generate the <database>.<table> for the queries and just have one context. I'll give that a shot. For my case, there are 100s of databases, so having a context for each is probably bad.
Lyall Jonathan Di Trapani
@lj-ditrapani
Actually, dynamicQuerySchema is what I want.
Lyall Jonathan Di Trapani
@lj-ditrapani
So, needed to downgrade to 3.5.2 for dynamicQuerySchema to work, in case anyone reads this.

@danellis
Can someone explain how I should turn this into a Quill query? I can't seem to get the groupBy and the filter to work properly. The SQL query itself does give me what I want.
SELECT
    posts.id, posts.title, COUNT(clicks.id)
FROM
    posts LEFT OUTER JOIN clicks ON posts.id = clicks.post_id
WHERE
    posts.author_id = '269286af-3be5-4dad-8b17-96704742b9a5'
    AND posts.timestamp > current_timestamp - '2 week'::interval
GROUP BY
    posts.id
Dan Ellis
@danellis

This was my best attempt:

for {
    post <- Posts
        .leftJoin(Clicks).on((p, c) => p.id == c.postId)
        .map { case (post, _) => post }
        .filter(p => p.authorId == lift(userId) && p.isDeleted == lift(false))
    clickCount <- Clicks
        .groupBy(_.postId)
        .map { case (_, clicks) => clicks.size }
} yield ClickCount(post.id, post.title, clickCount)

but that gives me this compile-time error:

exception during macro expansion: 
java.lang.IllegalStateException: The monad composition can't be expressed using applicative joins. Faulty expression: 'p.id'. Free variables: 'List(p)'., Faulty expression: 'p.title'. Free variables: 'List(p)'.
Dan Ellis
@danellis
I think I'm getting closer, but the generated query still uses COUNT(*). How can I change that to COUNT(clicks.id)?
