I am trying to do the following insert operation: cursor.execute(""" insert into tree (id,parent_id,level,description,code,start,end) values (%d,%d,%d,%s,%s,%f,%f) """, (1,1,1,'abc','def',1,1) ) The structure of my MYSQL table is: id int(255), parent_id int(255), level int(11), description varchar(255), code varchar(255), start decimal(25,4), end decimal(25,4) However when I run my program, I get the error " File "/usr/lib/pymodules/python2.6/MySQLdb/cursors.py", line 151, in execute query = query % db.literal(args) TypeError: %d format: a number is required, not str" Keith The format string

I just solved some problems in my Django 1.3 app by using PyMySQL instead of MySQLdb. I followed this tutorial on how to make the switch: http://web-eng-help.blogspot.com/2010/09/install-mysql-5-for-python-26-and.html Now I want to know what PyMySQL actually is and how it is different from MySQLdb. I am using it on localhost and will then upload it to some hosting. Is it fine to use PyMySQL on localhost and on hosting whatever they provide? Since I have changed "MySQLdb" in base.py and introspection.py to "PyMySQL", will I need to upload it to the server after changing these files? Or as it is

I'm looking for a way to debug queries as they are executed and I was wondering if there is a way to have MySQLdb print out the actual query that it runs, after it has finished inserting the parameters and all that? From the documentation, it seems as if there is supposed to be a Cursor.info() call that will give information about the last query run, but this does not exist on my version (1.2.2). This seems like an obvious question, but for all my searching I haven't been able to find the answer. Thanks in advance. xitrium We found an attribute on the cursor object called cursor._last_executed

This question already has an answer here: Python sqlite3 parameterized drop table 1 answer I'm trying to use a variable for a table name. I get the error "... near ''myTable'' at line 1 I must not be escaping this right. The double '' in the error seems to be a clue, but I don't get it. db = MySQLdb.connect("localhost","user","pw","database" ) table = "myTable" def geno_order(db, table): cursor = db.cursor() # prepare a cursor object using cursor() method sql = "SELECT * FROM %s" cursor.execute(sql, table) results = cursor.fetchall() Daniel Roseman You can't use a parameter for the table name

Both methods return a list of the returned items of the query, did I miss something here? Or they have identical usages indeed? Any differences performance-wise? If you are using the default cursor, a MySQLdb.cursors.Cursor , the entire result set will be stored on the client side (i.e. in a Python list) by the time the cursor.execute() is completed. Therefore, even if you use for row in cursor: you will not be getting any reduction in memory footprint. The entire result set has already been stored in a list (See self._rows in MySQLdb/cursors.py). However, if you use an SSCursor or

I'm trying to get this Python MYSQL update statement correct(With Variables): cursor.execute ("UPDATE tblTableName SET Year=%s" % Year ", Month=%s" % Month ", Day=%s" % Day ", Hour=%s" % Hour ", Minute=%s" Minute "WHERE Server=%s " % ServerID) Any ideas where I'm going wrong? It should be : cursor.execute (""" UPDATE tblTableName SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s WHERE Server=%s """, (Year, Month, Day, Hour, Minute, ServerID)) You can also do it with basic string manipulation, cursor.execute ("UPDATE tblTableName SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s WHERE Server='
