MySQL LIMIT
Natijani cheklash
"LIMIT" iborasidan foydalanib, so‘rovdan qaytarilgan yozuvlar sonini cheklashingiz mumkin:

"Mijozlar" jadvalidagi 5 ta birinchi yozuvni tanlang:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
password="yourpassword",
database="mydatabase"
)
mycursor = mydb.cursor()
mycursor.execute("SELECT * FROM customers LIMIT 5")
myresult = mycursor.fetchall()
for x in myresult:
print(x)

Boshqa pozitsiyadan boshlang
Agar siz uchinchi yozuvdan boshlab beshta yozuvni qaytarmoqchi bo‘lsangiz, "OFFSET" kalit so‘zidan foydalanishingiz mumkin:
Misol
3-pozitsiyadan boshlang va 5 ta yozuvni qaytaring:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
password="yourpassword",
database="mydatabase"
)
mycursor = mydb.cursor()
mycursor.execute("SELECT * FROM customers LIMIT 5 OFFSET 2")
myresult = mycursor.fetchall()
for x in myresult:
print(x)
