quill.io - 是否可以使用 IN 使用 Quill 更新多行

Question

有可能产生类似的东西

UPDATE employees SET gender = 'Male' WHERE id IN ('asfd','bleh');

与奎尔？我在文档中没有找到示例，批量更新似乎是别的东西。

它对我有用（试试https://scastie.scala-lang.org/）：

静态查询：

import io.getquill._

val ctx = new SqlMirrorContext(PostgresDialect, SnakeCase)

import ctx._

case class Product(name: String, price: Int)

def products(names: Seq[String], name: String) =
    ctx.run {
      ctx
        .query[Product]
        .filter(person => quote(liftQuery(names).contains(person.name)))
        .update(_.name -> lift(name))
}

val m = products(Seq("AA", "BB"), "EE")

println(m.string)

动态查询

import io.getquill._

val ctx = new SqlMirrorContext(PostgresDialect, SnakeCase)

import ctx._

case class Product(name: String, price: Int)

def products(names: Seq[String], name: String) =
    ctx.run {
      ctx
        .dynamicQuery[Product]
        .filter(person => quote(liftQuery(names).contains(person.name)))
        .update(setValue(_.name, name))
}

val m = products(Seq("AA", "BB"), "EE")

println(m.string)

输出：

UPDATE product SET name = ? WHERE name IN (?, ?)
