@joellabes I didn't add these changes to the original PR as it seemed like an additional enhancement to me. Would you be happy for these changes to go in too? |

I like it! My only request is that we call it relation_alias
, so that its interface aligns with the star macro which has similar behaviour. Just makes it easier for people to guess the correct argument name without checking the docs, if they already know the concept from a different macro.
I had considered this initially but felt like the argument is quite different to the |
Yeah it's not exactly the same, but I think it still works! Thanks for your contribution ⭐ |

branchDescription & motivation
It occurred to me that quite often one might want to first filter a model and then deduplicate it. The requirement for
deduplicate
to take a relation (in order to be able to return the correct columns) makes this difficult. By adding analias
argument we allow the macro to find the columns from a relation but to select from a CTE.Checklist

macro in place of the literal string:limit 0
