I am using the python.mysql
connector to access a MySQL table.
The MySQL database has a table policy_data
which has a few columns, one being application_no
.
The application_no
column has values in the form of t000...
totaling 8 digits including t
.
Ideally, the first value of application_no
column is t0000001
.
So I pass a command (from Python):
cursor.execute(select* application_no from policy_data where...(some condition)
data = cursor.fetchall()
appl = data[0][0] # this should give me 't0000001'
Here's the problem: I tried the above command as it is on MySQL, and it gives me t0000001
. But from Python (the above code), the value (appl=data[0][0]
) is coming as t
.
I even tried putting the received value inside str()
, but it still doesn't work.
data=cursor.fetchall()
returns a list of tuples (one tuple for each row of your table)
appl=data[0][0]
returns the first element of the first tuple namely the value of first column of first row in your query result.
Given this, if column 'application_no'
is second in your query result (and it is as you use * in your query) you will get the values of this column with data[i][1]
So if you check for aapl=data[0][1]
it sould return your desired output 't0000001'
