  • Insert record into mysql db with Entity Framework

    - by sanfra1983
    Hi, the problem is that it will insert a new record in a mysql table, I have already done the mapping of the mysql db and I have already done tests returning data and everything works. Now I read from a file, where there are queries written, I have them run me back and the result of true or false based on the final outcome of single query written to the file. Txt; I did this: using (var w = new demotestEntities ()) ( foreach (var l listaqueri) ( var p = we.CreateQuery <category> (l); we.SaveChanges (); result = true; ) ) but it does not work, I sense that it returns no errors, but neither the result given written in the query. txt file is as follows: INSERT INTO category (id, name) VALUES (null, 'test2') anyone can help me?

  • I cannot log in after theme change

    - by sssuizaaa
    After changing the gtk-theme in the gnome tweak took I was taken out of the session to the login screen and now I cannot log in. I can only log in using the guest account. So in the grub menu I selected the recovery mode and in the resulting menu I selected root-drop to root shell prompt. Once there I did a couple of things I've found in several pages and in the forums. 1.gsettings reset org.gnome.desktop.interface gtk-theme This is what I got: (process:642):WARNING: Command line 'dbus-launch –autolunch=4438d024dd45ef7fb2d3f4ab0000000f –binary-syntax --close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed.\n and nothing changes 2.gconftool-2 --type=string -s /desktop/gnome/interface/gtk_theme Radiance with this I was trying to change the gtk theme to the Radiance one. No strange message this time but it did not work either. I still cannot log in. Any ideas please?? sssuizaaa

  • Find groups with both validated, unvalidated users

    - by Matchu
    (Not my real MySQL schema, but illustrates what needs done.) Users can belong to many groups, and groups have many users. users: id INT validated TINYINT(1) groups: id INT name VARCHAR(20) groups_users: group_id INT user_id INT I need to find groups that contain both validated and unvalidated users (validated being 1 or 0, respectively), in order to perform a specific manual maintenance task. There are thousands of users, all belong to at least one group, but a group usually only has 2-5 users. This is a live production server, so I could probably craft a query myself, but the last one I tried took a matter of minutes before I killed it. (I'm not one of those brilliant SQL wizards.) I suppose I could take the server down for maintenance, but, if possible, a query that gets this job done in a matter of seconds would be fantastic. Thanks!

  • Need help setting up json array

    - by torr
    A database query returns several rows which I loop through as follows: foreach ($query->result() as $row) { $data[$row->post_id]['post_id'] = $row->post_id; $data[$row->post_id]['post_type'] = $row->post_type; $data[$row->post_id]['post_text'] = $row->post_text; } If I json_encode the resulting array ($a['stream']) I get { "stream": { "1029": { "post_id": "1029", "post_type": "1", "post_text": "bla1", }, "1029": { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, "1029": { "post_id": "1031", "post_type": "2", "post_text": "bla3", } } } But the json should actually look like this: { "stream": { "posts": [{ "post_id": "1029", "post_type": "1", "post_text": "bla1", }, { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, { "post_id": "1031", "post_type": "2", "post_text": "bla3", }] } } How should I build my array to get this json right?

  • Custom object based on database table

    - by Archangel
    Suppose that I have a database query which looks like below - select name, gender, birthday from person where person_id = 1; When this query is executed, some records from the database are returned. I want to make a custom object which will contain the exact attributes as the column names, with the corresponding values. As an example, suppose that the object is X. So it will have three attributes which are X.name, X.gender and X.birthday, with the corresponding values from the records. Is it doable in PHP? If so, then how?

  • Ordering by multiple columns in mysql with subquery

    - by Scarface
    Hey guys I have a query that selects data and organizes but not in the correct order. What I want to do is select all the comments for a user in that week and sort it by each topic, then sort the cluster by the latest timestamp of each comment in their respective cluster. My current query selects the right data, but in seemingly random order. Does anyone have any ideas? select * from ( SELECT topic.topic_title, topic.topic_id FROM comments JOIN topic ON topic.topic_id=comments.topic_id WHERE comments.user='$user' AND comments.timestamp>$week order by comments.timestamp desc) derived_table group by topic_id

  • How can I (both) create a row and accessing that row in the same 'Stored Procedure'?

    - by Richard77
    Hello, I'd like to get the value of the id column for an object just after I've created it. But I don't want to run another query for that. My book for beginner (SQL Server 2008 for Dummies) says that there are 2 tables (inserted and deleted) that hold the last row(s) that have been inserted, updated, or deleted. Unfortunately, only Triggers (says the book) can access those tables. But, if I use triggers, they will go off each time I "insert" a row even when I don't need them that functionality. Can I obtain the same effect with a Store Procedure (without having to run a separate query?) This is what I'm trying to do CREATE PROCEDURE myProcedure DECLARE @OrganizationName @ColumnID OUTPUT AS INSERT INTO Organization (OrganizationName) VALUES (@OrganizationName) SET @ColumnID = (// Please, I need Help here ...) Thanks for helping

  • How to bring out checboxes based on drop down list selection from DB

    - by user2199877
    I got stuck again. Can't overcome this step: loop through (in a form of checkboxes) pallets based on the lot drop down list selection, so it can be further submitted to complete the table. Please, please help. So, basically, first submit button (drop down menu) brings into the table lot number and description and also checkboxes to choose pallets. Second submit button (checboxes) brings into the table pallets numbers and weights.

  • How do I do proximity search in Oracle right?

    - by hko19
    Oracle's NEAR operator for full text search returns a score based on the proximity of two or more query terms. For example: near((dog, bite), 6) matches if 'dog' and 'bite' occurs within 6 words. What if I'd like it to match if either 'dog' or 'cat' or any other type of animal occurs within 6 words of the word 'bite'? I tried: near(((dog OR cat OR animal), bite), 6) but I got: NEAR operand not a phrase, equivalence or another NEAR expression Rather than expanding all possible combination into multiple NEAR and 'or' them together, what is the proper way to write such query?

  • Scalable way of doing self join with many to many table

    - by johnathan
    I have a table structure like the following: user id name profile_stat id name profile_stat_value id name user_profile user_id profile_stat_id profile_stat_value_id My question is: How do I evaluate a query where I want to find all users with profile_stat_id and profile_stat_value_id for many stats? I've tried doing an inner self join, but that quickly gets crazy when searching for many stats. I've also tried doing a count on the actual user_profile table, and that's much better, but still slow. Is there some magic I'm missing? I have about 10 million rows in the user_profile table and want the query to take no longer than a few seconds. Is that possible?

  • SQL: Join Parent - Child tables

    - by pray4Mojo
    I'm building a simple review website application and need some help with SQL Query. There are 3 tables (Topics, Comments, Users). I need a SQL query to select the data from all 3 tables. The 'Topics' table is the parent and the 'Comments' table contains the child records (anywhere from zero to 100 records per parent. The third table 'Users' contains the user information for all users. Here are the fields for the 3 tables: Topics (topicID, strTopic, userID) Comments (commentID, topicID, strComment, userID) Users (userID, userName) I tried: SELECT * FROM Topics Inner Join Comments ON Topics.topicID = Comments.topicID Inner Join Users ON Topics.userID = Users.userID But this does not work correctly because there are multiple topics and the User info is not joined to the Comments table. Any help would be appreciated.

  • Can I make PDOStatement->fetchObject not use non-member variables?

    - by threendib
    Lets say I have a class like this: Class User { var $id var $name; } And I run a query using PDO in php like so: $stm = $db->prepare('select * from users where id = :id'); $r = $stm->execute(array(':id' => $id)); $user = $r->fetchObject('User'); If I vardump my user object it has all kinds of other fields in it that I have not defined in the User class. Obviously I could make my query specific so that it only gives me back the fields I need/want. But if I don't want to do that is there any way to make this work the way I want it to? I like the idea of fetchObject, because it's one line of code to create this object and set member variables for me. I just don't want it to set variables I haven't defined in my class.

  • Best indexing strategy for several varchar columns in Postgres

    - by Corey
    I have a table with 10 columns that need to be searchable (the table itself has about 20 columns). So the user will enter query criteria for at least one of the columns but possibly all ten. All non-empty criteria is then put into an AND condition Suppose the user provided non-empty criteria for column1 and column4 and column8 the query would be: select * from the_table where column1 like '%column1_query%' and column4 like '%column4_query%' and column8 like '%column8_query%' So my question is: am I better off creating 1 index with 10 columns? 10 indexes with 1 column each? Or do I need to find out what sets of columns are queried together frequently and create indexes for them (an index on cols 1,4 and 8 in the case above). If my understanding is correct a single index of 10 columns would only work effectively if all 10 columns are in the condition. Open to any suggestions here, additionally the rowcount of the table is only expected to be around 20-30K rows but I want to make sure any and all searches on the table are fast. Thanks!

  • Double Inner Join generates unexpected error

    - by Itamar Marom
    In my database I have three tables: Users: UserID (Auto Numbering), UserName, UserPassword and a few other unimportant fields. PrivateMessages: MessageID (Auto Numbering), SenderID and a few other fields defining the message content. MessageStatus: MessageID, ReceiverID, MessageWasRead (Boolean) What I need is a query to which I input a user's id and I get all the private messages he has received. In addition, I also need to receive each message's sender UserName. For this I wrote the following query: SELECT Users.*, PrivateMessages.*, MessageStatus.* FROM PrivateMessages INNER JOIN Users ON PrivateMessages.SenderID = Users.UserID INNER JOIN MessageStatus ON PrivateMessages.MessageID = MessageStatus.MessageID WHERE MessageStatus.ReceiverID=[@userid]; But for some reason when I try saving it in my Access database, I get the following error (translated to English by me, since my office is in a different language): Syntax error (missing operator) at expression: "PrivateMessages.SenderID = Users.UserID INNER JOIN MessageStatus ON PrivateMessages.MessageID = MessageStatus.MessageI". Any ideas what could cause this? Thanks.

  • How to work around the home directory changing to /root when using sudo?

    - by Nathanel Titane
    Hello everybody! With Natty coming out soon, I've been at work updating my deployment and self-config script to make my desktop on 11.04 run and look the way I want it to. One bummer is that dbus seems to have changed and does not permit, in the same manner Lucid and Maverick did, the authentication of the current user by terminal call using grep and cat. Ideally, to run the script, I would sudo -s and then launch it as # chmod +x install && ./install Instead of returning my user name.. it now returns root and applies changes to the root profile and aborts whenever paths do not correspond. Here is my script header: #!/bin/bash ON_USER=$(echo ~ | awk -F'/' '{ print $1 $2 $3 }' | sed 's/home//g') export $(grep -v "^#" ~/.dbus/session-bus/`cat /var/lib/dbus/machine-id`-0) if sudo -u $ON_USER test -z "$DBUS_SESSION_BUS_ADDRESS" ; then eval `sudo -u $ON_USER dbus-launch --sh-syntax --exit-with-session` fi RELEASE=$(lsb_release -cs) How could I make it return the actual user now that natty is coming? Thanks for the help

Does anyone know a faster way to return document counts? phraseList = ["some phrase 1", "some phrase 2"] #etc, a list of phrases... countsearcher = IndexSearcher(SimpleFSDirectory(File(STORE_DIR)), True) analyzer = StandardAnalyzer(Version.LUCENE_CURRENT) for phrase in phraseList: query = QueryParser(Version.LUCENE_CURRENT, "contents", analyzer).parse("\"" + phrase + "\"") scoreDocs = countsearcher.search(query, 200).scoreDocs print "count is: " + str(len(scoreDocs))

  • Why should I use a web framework's template language over python's templating options?

    - by stariz77
    I'm coming from a python CGI background and was wanting to move into something more contemporary and think I have decided upon web.py as the framework I would like to use. In regards to templating, previously I used formatted strings and the string.Template module to effect most of my templating needs. After reading through a few of the templating options I have heard mentioned, I began wondering what the main benefits of using something like the Django or jinja templating options over "native" Python templating options were? Am I just going to be replacing $tmpl_var with {{ tmpl_var }} and s.substitute(tmpl_var=value) with t.render(s), i.e., alternate syntax? or will I gain additional advantages from using these templating systems?

  • [Symfony] Admin generator and i18n

    - by David
    I have read lots of questions about i18n, but I haven't found any about performance. I have a simple backend app listing the contents of an ads table. These ads have a category, that is translated in some languages (it's defined as i18n in the Doctrine schema). So, when I add a "table_method" in my generator.yml to include de Category table, it reduces the number of queries, but there are yet some of them referencing i18n translation tables. So, if I add the category Translation table to the query, it reduces even more the queries BUT it increases the processing time considerably. Why this time penalty? Just because of the translation table? And why isn't the filter using this method to avoid so many translation queries as well? I mean, if I want to filter by category, it is making one query per category to include the translation table. Why??

  • Filter objects within two seconds of one another using SQLAlchemy

    - by Arrieta
    Hello: I have two tables with a column 'date'. One holds (name, date) and the other holds (date, p1, p2). Given a name, I want to use the date in table 1 to query p1 and p2 from table two; the match should happen if date in table one is within two seconds of date in table two. How can you accomplish this using SQLAlchemy? I've tried (unsuccessfully) to use the between operator and with a clause like: td = datetime.timedelta(seconds=2) q = session.query(table1, table2).filter(table1.name=='my_name').\ filter(between(table1.date, table2.date - td, table2.date + td)) Any thoughts?
