Question

How can we fetch details of particular row from mysql database using variable in python?

I want to print the details of particular row using variable from my database and I think I should use something like this:

data = cur.execute("SELECT * FROM loginproject.Pro WHERE Username = '%s';"% rob)

But this is showing only the index value, not the data. Please help me out.

Answer 1

使用cur.execute（query）执行查询后，您需要调用fetchall函数以从游标获取数据，例如：

data = cur.fetchall()

Answer 2

Something like this?

cur = db.cursor()
cur.execute("SELECT * FROM loginproject.Pro WHERE Username = '%s';"% rob)
result = cur.fetchall()
for row in result:
  print(row[0])

python3.6 library: pip install mysqlclient

Answer 4

use cursor.fetchall and cursor.description is your case

cursor.fetchall():

This will provide you all the rows fetched in a tuple format.

cursor.description:

This will provide you the list of columns in the query

And the one will go like :

cur.execute("SELECT * FROM loginproject.Pro WHERE Username = '%s';"% rob)
descriptor = cur.description
result = cur.fetchall()
