UpdateJSON.runDDL()

The UpdateJSON.runDDL() method is a utility that executes DDL statements against the store using KVStore.executeSync().

This method relies on the UpdateJSON.displayResult() method, which simply writes the results of the DDL execution to the command line. It is shown later in this example.

    // Executes DDL statements (such as are found in defineTable()
    // and createIndex()) in the store.
    private boolean runDDL(KVStore kvstore, String statement) {
        StatementResult result = null;
        boolean success = false;

        try {
            result = kvstore.executeSync(statement);
            displayResult(result, statement);
            success = true;
        } catch (IllegalArgumentException e) {
            System.out.println("Invalid statement:\n" + e.getMessage());
        } catch (FaultException e) {
            System.out.println
                ("Statement couldn't be executed, please retry: " + e);
        }

        return success;
    }
