-- Deprecate legacy JSON columns in rides table
|
|
-- These columns violate the architectural rule: "NEVER STORE JSON IN SQL COLUMNS"
|
|
-- Use relational tables instead:
|
|
-- - ride_technical_specifications (for technical_specs)
|
|
-- - ride_coaster_statistics (for coaster_stats)
|
|
-- - ride_name_history (for former_names)
|
|
|
|
-- Mark columns as deprecated with comments
|
|
