Defined in Napkin.Render.Types |
withAs_ :: Selected Query -> Q (Ref Table) #
Define a WITH subquery while retaining and re-using its given name. Useful in some scenarios where you want to keep the original name in further referring to the newly introduced subquery table.
withAsUnique :: Selected Query -> Q (Ref Table) #
Use unique naming scheme along with Ref Relation to construct the WITH macro's name. This is useful when ensuring unique naming while not throwing out some human-readable information.
select_ :: SExp -> Q (Ref SExp) #
Smart selector that will use the variable's name if expression is a variable and assign a fresh variable name if it's something else without a name.
selectsGroupsAs_ :: [Selected SExp] -> Q () #
Select a field and also include it in GROUP BY. Do this intelligently, referring to it by its given name in most cases but by its direct expression definition in case of external functions to prevent overlap with fields that may already exist.
selectsGroupsAsRef_ :: [Selected SExp] -> Q () #
Like selectsGroupsAs_
but will use the name you gave to each
field in the group by statement. Some backends like BigQuery
require this while others like Redshift don't like it.
selectNonEmptyGroups :: [Selected SExp] -> Q () #
Special convenience case: Select and group while demanding that none of the group values is null.
fromIfNecessary :: Relation -> Q (Ref Relation) #
Add a from clause unless the relation is already in place.
fromRef_ :: Ref Relation -> Q (Ref Relation) #
Use a name directly and don't alias it one more time. | This can fail to create a proper alias if the Ref includes multiple names.
fromSpecified :: Q Bool #
Returns True iff the current Query already has an initial From table available.
fromOrJoin :: Alias Relation -> Either (Ref Relation -> Maybe SExp) [Ref SExp] -> Q (Ref Relation) #
joinSelected_ :: JoinType -> Selected Relation -> Either (Ref Relation -> Maybe SExp) [Ref SExp] -> Q (Ref Relation) #

whereAddNotIn :: MonadState QState m => SExp -> [SExp] -> m () #
where x not in y
limit_ :: MonadState QState m => Int -> m () #
offset_ :: MonadState QState m => Int -> m () #
scopeRelation :: SExp -> Relation -> Relation #
Make a query relation that applies predicate on the given relation in a subquery.
selectEverything :: [(Ref Relation, DefinedQuery)] -> Q () #
Introspects the given list of Query
ies, along with their
references in the current context, and selects every named field in
them within the current context, while deduplicating repeat fields
(by name). Good for the common case of joining tables and selecting
everything possible in them.
explicitSelectStar :: HasDefinition s => s -> Ref Relation -> Q () #
Instead of doing a select * that's impossible to introspect, explicitly select all fields from something that contains a definition - e.g. a Query.
selectNonDuplicates :: Foldable t => t (Ref SExp) -> Q () #
Given a list of references, select those that have not yet been selected in current monadic block.
mapSelectNonDuplicates :: Foldable t => t (Ref SExp) -> (Selected SExp -> Selected SExp) -> Q () #
Given a list of references, select those that have not yet been selected in current monadic block with option to modify the finalized selection.
