Fetching results from parameterized statement in C++ libneo4j_client












1















This is a follow up question regarding fetching the data from a parameterized query. Consider the following code:



const char *neo4j_query = "MATCH (p:Person) WHERE p.age > {age} RETURN p.name AS name, p.age as AGE";

neo4j_map_entry_t map_entry = neo4j_map_entry("age", 28);

neo4j_value_t params = neo4j_map(&map_entry, 1);

neo4j_run(session, q, params);


When I try to fetch the data using:



neo4j_result_stream_t *results = neo4j_run( session, neo4j_query, params);

if (results == NULL)

{

    neo4j_perror(stderr, errno, "Failed to run statement");

    printf( "%st%sn", move_details->move, neo4j_query);

    return EXIT_FAILURE;

}



neo4j_result_t *result = neo4j_fetch_next(results);

if (result == NULL)

{

    neo4j_perror(stderr, errno, "Failed to fetch result");

    return EXIT_FAILURE;

}


I get the following message 



Failed to fetch result: Success


Question is if there is any special way to fetch results?
