  • Mac OS X, Can't start/stop MySQL via System Preferences

    - by Steve Kuo
    I downloaded and installed MySQL 5.1.47 for OS X 10.6 using the DMG archive: mysql-5.1.47-osx10.6-x86_64.dmg I also installed MySQL.prefPane and MySQLStartupItem.pkg. MySQL.prefPane is a Preference Pane. The problem is, whenever I attempt to start/stop MySQL from the Preference Pane, System Preferences just hangs. It runs at about 50% CPU forever, eventually I have for force quit System Preferences. The same thing happens if I toggle "Automatically Start MySQL Server on Startup". Basically the MySQL Preference Pane is not functional. Note that I have no problem starting MySQL from the command line: sudo /usr/local/mysql/bin/mysqld_safe I have tried reinstalling MySQL and the Preference Pane. I'm using the standard installation location, nothing out of the ordinary. Every time the MySQL Preference Pane just hangs. I'm doing this on a Macbook Pro (Intel) running OS X 10.6.3. There are no old versions of MySQL on this machine.

  • Terminate a python script from another python script

    - by Nick
    I've got a long running python script that I want to be able to end from another python script. Ideally what I'm looking for is some way of setting a process ID to the first script and being able to see if it is running or not via that ID from the second. Additionally, I'd like to be able to terminate that long running process. Any cool shortcuts exist to make this happen?

  • changing Python code in the debugger

    - by max
    Is there any debugger that allows Python code to be changed while debugging? In other words: run-time exception occurs, debugger stops, I change the code any way I like, and tell the program to continue. I am aware of the problems with this approach, such that references to functions would still point to the old definitions if I redefine the function on the fly, and so on. I am ok with that, since I just want to be able to make small fixes in very simple circumstances. On the other hand, I'm also interested in whether it's theoretically possible to allow changes to Python code without running into these problems: i.e., somehow update all the references to the objects that changed, etc. I'm nearly sure the answer to the second question is no, but if I'm wrong, I'd like to know. EDIT: If my goal (changing the code interactively when an exception occurred, and then continuing execution), is achievable without a debugger - that would be good as well. I don't need to use the debugger.

  • compare previous ENCRYPT() call with new ENCRYPT() call mysql

    - by contagious
    I'm storing a string in mysql with the ENCRYPT() function. I want to fetch a row where that string is matched, but the new ENCRYPT() call gives me a different value, so they never match. This is expected as i'm not (and can't) give it a consistent salt: http://dev.mysql.com/doc/refman/5.0/en/encryption-functions.html#function_encrypt If no salt argument is given, a random value is used. This is the query i'm running that returns empty: SELECT * FROM `table` WHERE ENCRYPT('string') = `enc_string` I know this is possible because this is used by a 3rd party app, but I can't find their query where they do this. Is there a way to force ENCRYPT to use the previous salt, or predict it?

  • Trying to find a match in two strings - Python

    - by Jacob Mammoliti
    I have a user inputting two strings and then I want to check if there are any similar characters and if there is, get the position where the first similarity occurs, without using the find or index function. Below is what I have so far but I doesn't fully work. With what I have so far, I'm able to find the similarities but Im not sure how to find the position of those similarities without using the index function. string_a = "python" string_b = "honbe" same = [] a_len = len(string_a) b_len = len(string_b) for a in string_a: for b in string_b: if a == b: same.append(b) print (same) Right now the output is: ['h', 'o', 'n'] So basically what I am asking is, how can I find the position of those characters without using the Python Index function?

  • installing Python application with Python under windows

    - by mack369
    My application uses many Python libraries (Django, Twisted, xmlrpc). I cannot expect that the end user has the Python installed with all needed libraries. I've created a fancy installer for my application using Inno Setup, but I don't think that it is a good solution to execute 5 other setup programs from my installer. It would be annoying to the user to click "Next" button 15 times. Is there any way to do that quietly?

  • Setuptools Python namespace package in /opt

    - by Samuel Taylor
    I'm trying to get my app to install in /opt/[app_name] using setuptools. My app uses a namespace package. To install I run sudo python setup.py install --prefix=/opt/[app_name]/ --install-lib=/opt/[app_name]/ --install-scripts=/opt/[app_name]/ When I install it this was setuptools does not copy init.py in to my namespace package so when I come to run my app, python does not treat it as a package and I get import errors. if I create the init.py file my app works fine. How do I get setuptool to copy over the init.py file when using --install-lib and --prefix? Thanks Sam

  • Counting multiple entries in a MySQL database?

    - by Aaron
    Hi all, I'm trying to count multiple entries in a MySQL database, I know how to use COUNT(), but the exact syntax I want to get the results I need eludes me. The problem: Table structure: ID, CODE, AUTHOR, COUNTRY, TIMESTAMP. Code, Author and Country overlap many times in the table. I am trying to discover if there is one simple query that can be ran to return (using WHERE clause on COUNTRY) the author field, the code field, and then a final field that counts the number of times the CODE was present in the query result. So, theoretically I could end up with an array like: array('author', 'code', 'codeAppearsNTimes'); Authors also have varying codes associated with them, so I don't want the results merged. I suppose the end result would be: 'This author is associated with this code this many times'. Is this possible with MySQL? Thanks in advance.

What am I doing wrong here? Do I have to tell mysql somewhere that I can write to that directory?

  • MYSQL - Help with a more complicated Query

    - by Joe
    I have two tables: tbl_lists and tbl_houses Inside tbl_lists I have a field called HousesList - it contains the ID's for several houses in the following format: 1# 2# 4# 51# 3# I need to be able to select the mysql fields from tbl_houses WHERE ID = any of those ID's in the list. More specifically, I need to SELECT SUM(tbl_houses.HouseValue) WHERE tbl_houses.ID IN tbl_lists.HousesList -- and I want to do this select to return the SUM for several rows in tbl_lists. Anyone can help? I'm thinking of how I can do this in a SINGLE query since I don't want to do any mysql "loops" (within PHP).

  • Error in MySQL Workbench Forward Engineer Stored Procedures

    - by colithium
    I am using MySQL Workbench (5.1.18 OSS rev 4456) to forward engineer a SQL CREATE script. For every stored procedure, the automatic process outputs something like: DELIMITER // USE DB_Name// DB_Name// DROP procedure IF EXISTS `DB_Name`.`SP_Name` // USE DB_Name// DB_Name// CREATE PROCEDURE `DB_Name`.`SP_Name` (id INT) BEGIN SELECT * FROM Table_Name WHERE Id = id; END// The two lines that are simply the database name followed by the delimiter are errors and are reported as such when running the script. As long as they are ignored, it looks like everything gets created just fine. But why would it add those lines? I am creating the database in the WAMP environment which uses MySQL 5.1.36

  • How does mysql define DISTINCT()

    - by goran
    AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best

  • Mysql: ROLLBACK for multiple queries

    - by Raj
    Hi I have more than three MySql queiries in a PHP script triggered by scheduled task. If a query catch an error, script throw an exception and rollback that Mysql query. It works fine. However if first query works fine, but not 2nd query, throw an exception, it rollback 2nd one but not 1st query. I am using begin_trans(), commit and rollback() for individual queries because Sometimes i need to rollback one query, sometimes all queries. Is there any way to rollback one query or all queries? Thanks in advance UPDATE: I got it working, there was no problem with in begin_trans(), commit and rollback(), the database connection config was different for one query from other queries, crazy code without any comments!!!

  • Automatic logout in python web app

    - by Ali
    I have a web application in python wherein the user submits their email and password. These values are compared to values stored in a mysql database. If successful, the script generates a session id, stores it next to the email in the database and sets a cookie with the session id, with allows the user to interact with other parts of the sight. When the user clicks logout, the script erases the session id from the database and deletes the cookie. The cookie expires after 5 hours. My concern is that if the user doesnt log out, and the cookie expires, the script will force him to login, but if he has copied the session id from before, it can still be validated. How do i automatically delete the session id from the mysql database after 5 hours?

  • How to get top 3 frequencies in MySQL?

    - by Amenhotep
    Hello, In MySQL I have a table called "meanings" with three columns: "person" (int), "word" (byte, 16 possible values) "meaning" (byte, 26 possible values). A person assigns one or more meanings to each word: person word meaning ------------------- 1 1 4 1 2 19 1 2 7 <-- second meaning for word 2 1 3 5 ... 1 16 2 Then another person, and so on. There will be thousands of persons. I need to find for each of the 16 words the top three meanings (with their frequencies). Something like: word 1: meaning 5 (35% of people), meaning 19 (22% of people), meaning 2 (13% of people) word 2: meaning 8 (57%), meaning 1 (18%), meaning 22 (7%) ... Is it possible to solve this with a single MySQL query? (If this problem is a classic one and has been answered elsewhere, I would appreciate if you could give me a link to the solution.) Thank you very much, ve

  • MySQL floating point comparison issues

    - by Sharief
    I ran into an issue by introducing floating point columns in the MySQL database schema that the comparisons on floating point values don't return the correct results always. 1 - 50.12 2 - 34.57 3 - 12.75 4 - ...(rest all less than 12.00) SELECT COUNT(*) FROM `users` WHERE `points` > "12.75" This returns me "3". I have read that the comparisons of floating point values in MySQL is a bad idea and decimal type is the better option. Do I have any hope of moving ahead with the float type and get the comparisons to work correctly?

  • Which MySQL Fork/Version to Pick??

    - by Drew
    As most of you know, Sun acquired MySQL (and later Oracle acquired Sun), and during these acquisitions, there were a lot of FUD in MySQL community which resulted in creation of various forks. Today we have MySQL from MySQL, Percona (XtraDB) MySQL, OurDelta MySQL, MariaDB, Drizzle to name a few. Which brings us to the source of the problem. We are in the process of upgrading our databases (hardware/software) and I would like to know which one of the forks should I go with. Each has their own set of pros/cons. We are currently using MySQL 5.0.x from MySQL/Linux on an 8-core machine. Our new hardware is a monster with 32 cores and 32GB of memory connecting to a fast NetApp Storage via FC. I would like to stick with MySQL from MySQL but I have heard horror stories on how badly MySQL 5.1 performs on many cores. I have also heard that MySQL 5.4 performs better on multi-core machines but that's still not production ready. In addition, I have also heard a lot of good things about Percona builds. This is what I know so far: MySQL 5.1 from MySQL: Reliable choice, but doesn't scale well on a big machine Percona: Scales well, good backing company. I don't have much experience with it MariaDB: Don't know much about it besides that it was founded by Original MySQL developers (including Monty) OurDelta: Don't know much Drizzle: Mostly optimized for cloud computing I would like to know what's the general notion about this problem. Which build/version should I go with? How are you guys picking your builds/versions? Thanks!
