I am trying to retrieve data from an SQL server using pyodbc and print it in a table using Python. However, I can only seem to retrieve the column name and the data type and stuff like that, not the actual data values in each row of the column.
Basically I am trying to replicate an Excel sheet that retrieves server data and displays it in a table. I am not having any trouble connecting to the server, just that I can’t seem to find the actual data that goes into the table.
Here is an example of my code:
import pyodbc cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=SQLSRV01;DATABASE=DATABASE;UID=USER;PWD=PASSWORD') cursor = cnxn.cursor() cursor.execute("SELECT * FROM sys.tables") tables = cursor.fetchall() #cursor.execute("SELECT WORK_ORDER.TYPE,WORK_ORDER.STATUS, WORK_ORDER.BASE_ID, WORK_ORDER.LOT_ID FROM WORK_ORDER") for row in cursor.columns(table='WORK_ORDER'): print row.column_name for field in row: print field
However the result of this just gives me things like the table name, the column names, and some integers and ‘None’s and things like that that aren’t of interest to me:
STATUS_EFF_DATE DATABASE dbo WORK_ORDER STATUS_EFF_DATE 93 datetime 23 16 3 None 0 None None 9 3 None 80 NO 61
So I’m not really sure where I can get the values to fill up my table. Would it should be in table=’WORK_ORDER’, but could it be under a different table name? Is there a way of printing the data that I am just missing?
Any advice or suggestions would be greatly appreciated.

You are so close!
import pyodbc cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=SQLSRV01;DATABASE=DATABASE;UID=USER;PWD=PASSWORD') cursor = cnxn.cursor() cursor.execute("SELECT WORK_ORDER.TYPE,WORK_ORDER.STATUS, WORK_ORDER.BASE_ID, WORK_ORDER.LOT_ID FROM WORK_ORDER") for row in cursor.fetchall(): print row
(the “columns()” function collects meta-data about the columns in the named table, as opposed to the actual data).
