Feb 08, 2017 · You can't pass a Python list as a SQL parameter. The parameters have to correspond to single values - strings, integers, floats, datetime.date, etc. See the list of available object types on the wiki page https://github.com/mkleehammer/pyodbc/wiki/Data-Types, look for the "Python Datatype" column in the first table there.
The other parameter @r_rowsPerRead determines the number of batches in which to execute the code. So if your dataset has 10000 entries, and you set the @RowsPerRead parameter as 5000, the stored procedure will execute the script twice. This is especially good for large datasets and limited compute resources.

''', STARTDATE, ENDDATE) # SQL with parameters stop Plus, it's better to avoid passing dates as strings. Let pyodbc take care of that using Python's datetime:
Three lessons that I learned from this struggle: 1) kerberos is CASE SENSITIVE. Your kerberos realm in the string MUST be uppercase. 2) The Cloudera driver doesn't like spaces in between the semicolons in the string. Avoid them. 3) If you don't need connection pooling, turn it off with a pyodbc.pooling = False statement.
