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?

          SQL update select statement

          Image
          0 I'm trying to update an entry in my database (postgresql). I'm having a problem with updating the query: INSERT INTO prices (price, product_id) SELECT product_price, commn_id FROM products_temp as prod WHERE NOT EXISTS (SELECT * FROM prices od WHERE prod.commn_id = od.product_id) OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) Query works fine when i delete: OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) So it seems to me that it's looping through this operation. My question is, how can I fix it? sql postgresql
