Kutoa Rekodi Moja katika Python

Ikiwa unahitaji kupata rekodi moja tu kutoka kwenye jedwali, kuitoa kwa kutumia kitanzi hufanya msimbo uwe mzito. Ili kutatua tatizo hili, unahitaji kutumia mbinu fetchone:

pythonquery = "SELECT * FROM users WHERE id=2"
with connection.cursor(dictionary=True) as cursor:
  cursor.execute(query)
  result = cursor.fetchone()
  
  print(result)

Baada ya kutekeleza msimbo huu, rekodi moja tu itaonyeshwa:

python{'id': 2, 'name': 'user2', 'age': 25, 'salary': 500}

Sasa hebu tuweke sharti kwenye swali, ambalo linakidhi rekodi kadhaa:

pythonquery = "SELECT * FROM users WHERE salary>500"
with connection.cursor(dictionary=True) as cursor:
  cursor.execute(query)
  result = cursor.fetchone()
  
  print(result)

Katika hali hii, rekodi ya kwanza tu inayokidhi masharti yaliyowekwa itatolewa:

python{'id': 4, 'name': 'user4', 'age': 30, 'salary': 900}
