Functional variants of the query builder These are imperative function that are called for ery row. Warning: that these cannot be optimized by the query compiler, and may prevent some type of optimizations being possible.

Example

q.fn.select((row) => ({
  name: row.user.name.toUpperCase(),
  age: row.user.age + 1,
}))

q.fn.select((row) => ({
  name: row.user.name.toUpperCase(),
  age: row.user.age + 1,
}))
