renderOutputCompact :: CompatMode -> TADag -> MatFun -> ShowS

renderOutputPlain :: CompatMode -> TADag -> MatFun -> ShowS

renderDebugOutput :: CompatMode -> TADag -> MatFun -> Bool -> ShowS

Produces pretty output, optionally with debug information.

renderAdvancedDebugOutput :: CompatMode -> Bool -> Bool -> TADag -> MatFun -> String

Produces output which allows further inspection with the psql command line utility (and possibly others too).

renderOutputDSH :: CompatMode -> TADag -> (Maybe String, [String])

Render output directly for DSH. The order from the root nodes in the directed acyclic graph is preserved. (This function uses the combined materialization strategy.)

renderOutputDSHWith :: CompatMode -> MatFun -> TADag -> (Maybe String, [String])

Render output directly for DSH. The order from the root nodes in the directed acyclic graph is preserved.

putShowSLn :: ShowS -> IO ()
