How to retrieve SQL result column value using column name in Python?
Is there a way to retrieve SQL result column value using column name instead of column index in Python? I'm using Python 3 with mySQL. The syntax I'm looking for is pretty much like the Java construct:
Object id = rs.get("CUSTOMER_ID");
I've a table with quite a number of columns and it is a real pain to constantly work out the index for each column I need to access. Furthermore the index is making my code hard to read.
Thanks!
The MySQLdb module has a DictCursor:
Use it like this (taken from Writing MySQL Scripts with Python DB-API):
cursor = conn.cursor(MySQLdb.cursors.DictCursor)
cursor.execute("SELECT name, category FROM animal")
result_set = cursor.fetchall()
for row in result_set:
print "%s, %s" % (row["name"], row["category"])
edit: According to user1305650 this works for pymysql
as well.
This post is old but may come up via searching.
Now you can use mysql.connector to retrive a dictionary as shown here: https://dev.mysql.com/doc/connector-python/en/connector-python-api-mysqlcursordict.html
Here is the example on the mysql site:
cnx = mysql.connector.connect(database='world')
cursor = cnx.cursor(dictionary=True)
cursor.execute("SELECT * FROM country WHERE Continent = 'Europe'")
print("Countries in Europe:")
for row in cursor:
print("* {Name}".format(Name=row['Name']))
