Typeclass to indicate that we are able to evaluate a query of type Q to return a result of type R. Involves two operations: flattening a structured query to a flat list of expressions via walkLabelsAndExprs, and reading a JSON-ish tree-shaped blob back into a return value via valueReader

Abstract methods
Construct a Scala return value from the Queryable.ResultSetIterator representing the return value of this queryable value
Construct a Scala return value from the Queryable.ResultSetIterator representing the return value of this queryable value
Attributes
Whether this queryable value is executed using java.sql.Statement.executeUpdate instead of .executeQuery. Note that this needs to be known ahead of time, and cannot be discovered by just calling .execute, because some JDBC drivers do not properly handle updates in the .execute call

Attributes
Whether this query expects a single row to be returned, if so we can assert on the number of rows and raise an error if 0 rows or 2+ rows are present

Attributes
Returns a sequence of expressions created by this queryable value. Used to generate the column list SELECT clauses, both for nested and top level SELECTs

Attributes
Returns a sequence of labels, each represented by a list of tokens, representing the expressions created by this queryable value. Used to add AS foo_bar labels to the generated queries, to aid in readability
