I am trying to insert values into a column of a SQL table, using MySQLdb in Python 2.7. I am having problems with the command to insert a list into 1 column.
I have a simple table called 'name' as shown below:
+--------+-----------+----------+--------+
| nameid | firstname | lastname | TopAdd |
+--------+-----------+----------+--------+
| 1 | Cookie | Monster | |
| 2 | Guy | Smiley | |
| 3 | Big | Bird | |
| 4 | Oscar | Grouch | |
| 5 | Alastair | Cookie | |
+--------+-----------+----------+--------+
Here is how I created the table:
CREATE TABLE `name` (
`nameid` int(11) NOT NULL AUTO_INCREMENT,
`firstname` varchar(45) DEFAULT NULL,
`lastname` varchar(45) DEFAULT NULL,
`TopAdd` varchar(40) NOT NULL,
PRIMARY KEY (`nameid`)
) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8
Here is how I populated the table:
INSERT INTO `test`.`name`
(`firstname`,`lastname`)
VALUES
("Cookie","Monster"),
("Guy","Smiley"),
("Big","Bird"),
("Oscar","Grouch"),
("Alastair","Cookie");
DISCLAIMER: The original source for the above MySQL example is here.
Here is how I created the a new column named TopAdd:
ALTER TABLE name ADD TopAdd VARCHAR(40) NOT NULL
I now have a list of 5 values that I would like to insert into the column TopAdd as the values of that column. Here is the list.
vals_list = ['aa','bb','cc','dd','ee']
Here is what I have tried (UPDATE statement inside loop):
vals = tuple(vals_list)
for self.ijk in range (0,len(self.vals)):
self.cursor.execute ("UPDATE name SET TopAdd = %s WHERE 'nameid' = %s" % (self.vals[self.ijk],self.ijk+1))
I get the following error message:
Traceback (most recent call last):
File "C:\Python27\mySQLdbClass.py", line 70, in <module>

raise errorclass, errorvalue
_mysql_exceptions.OperationalError: (1054, "Unknown column 'aa' in 'field list'")
Is there a way to insert these values into the column with a loop or directly as a list?
