Where a naive translation goes wrong
- RAWSQL embeds source-dialect SQL; replace the template for the target database.
Naive SQL
SELECT label AS result FROM input
result cedar cedar ORCHID-west maple-east willow north birch-birch pine/south ash null Matches the calculation
SELECT lower(label) AS result FROM input
result cedar cedar orchid-west maple-east willow north birch-birch pine/south ash null
