Les exemples de code suivants illustrent comment utiliser DeleteSchemaMapping.
Les exemples d’actions sont des extraits de code de programmes de plus grande envergure et doivent être exécutés en contexte. Vous pouvez voir cette action en contexte dans l’exemple de code suivant :

/**
* Deletes the schema mapping asynchronously.

* @param schemaName the name of the schema to delete
* @return a {@link CompletableFuture} that completes when the schema mapping is deleted successfully,
* or throws a {@link RuntimeException} if the deletion fails
*/
public CompletableFuture<DeleteSchemaMappingResponse> deleteSchemaMappingAsync(String schemaName) {
DeleteSchemaMappingRequest request = DeleteSchemaMappingRequest.builder()
.schemaName(schemaName)
.build();
