rewrite_rule	function	go	core	1.0.0	pure	func RewriteRule(rule, jsonColumn string) string	Reescribe campos bare en una expresion SQL a llamadas json_extract sobre una columna JSON de SQLite.	sql json sqlite rewrite assertion				false		regexp	false			functions/core/rewrite_rule.go

Ejemplo

out := RewriteRule("price > 100 AND status IS NOT NULL", "metadata")
// out = "json_extract(metadata, '$.price') > 100 AND json_extract(metadata, '$.status') IS NOT NULL"

// Si ya tiene json_extract, no modifica nada
out = RewriteRule("json_extract(data, '$.x') > 0", "data")
// out = "json_extract(data, '$.x') > 0"

Notas

Funcion pura. Preserva keywords SQL y funciones SQLite conocidas. Util para construir queries dinamicas sobre columnas JSON en SQLite sin que el usuario tenga que escribir json_extract manualmente.
