Thanks for the video. Very helpful for me. Let's say 2 stores sell apples. Is there a way for me to create a relationship that shows which store I bought the apple from? what's the model?
hi please can you tell which function does it use ?
Thanks for the video, it was easy to follow, not rushed.
Good explanation
Hola Nesvit, soy un gran fanático de tu canal y me encantó el video en el que presentaste el gráfico de pronóstico. Me gustaría aprender más sobre cómo lo utilizaste y cómo obtuviste los datos para generar ese pronóstico. ¿Podrías compartir algunos detalles sobre tu proceso de creación del gráfico de forecast? ¿Qué métodos o herramientas utilizaste para recopilar los datos y generar las proyecciones? También estoy interesado en saber cómo interpretaste los resultados y cómo los aplicaste en tu contenido. ¡Muchas gracias por tu tiempo y sigue haciendo el excelente trabajo que haces!
Gracias por tus amables palabras, ¡significan mucho para mí! Me alegra ver que mis explicaciones son útiles. Claro, planearé agregar más videos y hablaré sobre la recopilación de datos, la simulación de datos, la creación de gráficos y la interpretación de resultados. Más contenido próximamente este otoño 😃
I imported my data already in nodes, so just went to code the MATCH and MERGE. It runs but gives no changes, no records, and creates no relationships. And it doesn't like " for strings, it only likes '. In MATCH I used 2 statements to describe the 2 records from different nodes I want the relationship on: so MATCH (lowercasenodename :CAPITALIZEDNODENAME {field: 'value'}] then a MERGE (lowercasenodename) ->[:RELNAME[ -> (lowercasenodename2) and the values I selected in the MATCH statments exist in their nodes so not sure why No changes, no records.
If you already have nodes and only need to create relationships, try to use the command RETURN after the MATCH statement to ensure you see the nodes, you want to connect. Usually, when the error says "no changes," it means you requested something "not real" to you, and the program can't find it. That's why command RETURN is helpful before MERGE. If you would like to get my assistance on this case, you can e-mail me at kateryna.nesvit@alivemath.io, I will be glad to help you resolve the issue.
Hi ! If you do not see changes, it means the existing data doesn't match what you requested. Check the spelling when you create and when you match data.
thank you very much 🙏🏿
Great video 👍
