JSON_REPLACE
Actualiza valores existentes en un objeto JSON según su ruta. JSON_REPLACE no agrega nuevas claves al documento; solo reemplaza los valores de las claves existentes.

[SELECT] [JSON_EXTRACT] [JSON_SET] [JSON_REPLACE]
Sintaxis
SELECT JSON_REPLACE(json_column, path, new_value) FROM <multipartIdentifier>;
Argumentos
json_column
La columna o expresión JSON en la que se reemplazan valores.
path
La expresión de ruta JSON que apunta a la ubicación del documento JSON donde debe realizarse el reemplazo. La ruta debe apuntar a una clave existente.
new_value
El nuevo valor de reemplazo en la ruta especificada del documento JSON.
Valor(es) devuelto(s)
Devuelve un documento JSON modificado con el valor especificado reemplazado. Si la ruta especificada no existe, el documento JSON original se devuelve sin cambios.
| Función | ¿Sobrescribir si ya existe? | ¿Crear si no existe? |
|---|---|---|
json_insert() | No | Sí |
json_replace() | Sí | No |
json_set() | Sí | Sí |
Ejemplos
Reemplazar un solo valor en un objeto JSON
SELECT sku as original,
JSON_REPLACE(sku, '$.name', 'Standard_EU') as updated
FROM azure.container_registry.registries
WHERE registry_name = 'exampleRegistryProd'
AND subscription_id = '12345678-abcd-1234-abcd-1234abcd5678'
AND resource_group_name = 'exampleResourceGroupProd';
/* expected output...
|---------------------------------------|------------------------------------------|
| original | updated |
|---------------------------------------|------------------------------------------|
| {"name":"Standard","tier":"Standard"} | {"name":"Standard_EU","tier":"Standard"} |
