@deepxg No, there's no other way to do this at the moment. Patch with tests and docs welcome!
This works now since a couple of releases. See: https://github.com/r0man/sqlingvo/blob/master/test/sqlingvo/select_test.cljc#L1018
Right now to cast an array to another type (or any type at all in the cast of empty arrays, which was my issue), you need to write:
`(cast ~array (keyword "int[]"))
. This is slightly non-obvious, given all Postgres error messages will point you towards just appending::integer[]
which doesn't seem possible in sqlingvo.Is there any merit to having an explicit
array-cast
function that gets around this, and the issue of ugly keywords with invalid characters? This way you could say`(array-cast ~array :int)
which seems slightly nicer. Either way, it would be great to have at least a note in the readme or a test to show how it's done.Apologies if I'm missing an existing way to do this more cleanly!
