• MySQL COUNT help

  - by space

  I'm trying to count all the ids form table3 that are related to the first two tables but I think my SQL code is wrong can some one help me fix it? Here is the code: $dbc = mysqli_query($mysqli,"SELECT table1.*, table2.*, COUNT(id) as num, table3.id FROM table1 INNER JOIN table2 ON table1.id = table2.id INNER JOIN table3 ON table2.id = table3.id WHERE table2.id = '$id'"); Here is the error message. Mixing of GROUP columns (MIN(),MAX(),COUNT(),...) with no GROUP columns is illegal if there is no GROUP BY clause You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4

• PHP MSSQL : How to display output when query return no row

  - by vamps

  i have a problem with my PHP-MSSQL query. i have a join table that need to give a result something be like this: Department Group A Group B Total A+B WORKHOUR A OTHOUR A WORKHOUR B OTHOUR B WORKHOUR OTHOUR HR 10 15 25 0 35 15 IT 5 5 5 5 Admin 12 12 12 12 the query will count how many employee as per given date (admin will enter data and once submitted, the query will give the above result). The problem is, the final output is a mess when there's no row to be displayed. the column is shifted to the right. i.e: only Group A in IT only Group B in Admin Department Group A Group B Total A+B WORKHOUR A OTHOUR A WORKHOUR B OTHOUR B WORKHOUR OTHOUR HR 10 15 25 0 35 15 IT 5 5 5 5 Admin 12 12 12 12 my question is, how to prevent this to happen? i've tried everything with While.... if else.. but the result is still the same. how to display output "0" if no rows to return? echo "0"; this is my QUERY: select DD.DPT_ID,DPT.DEPARTMENT_NAME,TU.EMP_GROUP, sum(DD.WORK_HOUR) AS WORK_HOUR, sum(DD.OT_HOUR) AS OT_HOUR FROM DEPARTMENT_DETAIL DD left join DEPARTMENT DPT ON (DD.DEPT_ID=DPT.DEPT_ID) LEFT JOIN TBL_USERS TU ON (TU.EMP_ID=DD.EMP_ID) WHERE DD_DATE>='2012-01-01' AND DD_DATE<='2012-01-31' AND TU.EMP_GROUP!=2 GROUP BY DD.DEPT_ID, DPT.DEPARTMENT_NAME,TU.EMP_GROUP ORDER BY DPT.DEPARTMENT_NAME this is one of the logic that i've used, but doesn't return the result that i want:: while($row = mssql_fetch_array($displayResult)) { if ((!$row["WORK_HOUR"])&&(!$row["OT_HOUR"])) { echo "<td >"; echo "empty"; echo "&nbsp;</td>"; echo "<td >"; echo "empty"; echo "&nbsp;</td>"; } else { echo "<td>"; echo $row["WORK_HOUR"]; echo "&nbsp;</td>"; echo "<td>"; echo $row["OT_HOUR"]; echo "&nbsp;</td>"; } } please help. i've been doing this for 2 days. @__@

• Linq to SQL - How to compare against a collection in the where clause?

  - by Sgraffite

  I'd like to compare against an IEnumerable collection in my where clause. Do I need to manually loop through the collection to pull out the column I want to compare against, or is there a generic way to handle this? I want something like this: public IEnumerable<Cookie> GetCookiesForUsers(IEnumerable<User> Users) { var cookies = from c in db.Cookies join uc in db.UserCookies on c.CookieID equals uc.CookieID join u in db.Users on uc.UserID equals u.UserID where u.UserID.Equals(Users.UserID) select c; return cookies.ToList(); } I'm used to using the lambda Linq to SQL syntax, but I decided to try the SQLesque syntax since I was using joins this time. What is a good way to do this?

• mysql stored routine vs. mysql-alternative?

  - by user522962

  We are using a mysql database w/ about 150,000 records (names) total. Our searches on the 'names' field is done through an autocomplete function in php. We have the table indexed but still feel that the searching is a bit sluggish (a few full seconds vs. something like Google Finance w/ near-instant response). We came up w/ 2 possibilities, but wanted to get more insight: Can we create a bunch (many thousands or more) of stored procedures to speed up searches, or will creating that many stored procedures bog-down the db? Is there a faster alternative to mysql for "select" statements (speed on inserting & updating rows isn't too important so we can sacrifice that, if necessary). I've vaguely heard of BigTable & others that don't support JOIN statements....we need JOIN statements for some of our other queries we do. thx

• NHibernate: References still being eagerly selected after specifying AddJoin

  - by cbp

  I have a query which is something like this: Session.CreateSQLQuery( @"SELECT f.*, b.*, z.* FROM Foo f LEFT OUTER JOIN Bar b ON b.Id = f.BarId LEFT OUTER JOIN Zar z ON z.Id = b.ZarId" ) .AddEntity("f", typeof(Foo)) .AddJoin("b", "f.BarId") .AddJoin("z", "f.ZarId") .List<Foo>(); The problem is that I am still getting hundreds of SELECT requests made to the Zar table, even though I have specified that Zar should be joined. As far as I am aware the only relationship is Foo-Bar-Zar, i.e. the reference to Zar is not occurring anywhere else. Is my understanding of AddJoin correct? What could be going wrong? List item

How could I get the unlinked result independent on the context? Thanks

• Can I bypass an intermediate object in hibernate

  - by Jherico

  I have top level entities TRACK, MEDIA_GROUP and MEDIA, each with an integer primary key. I also have a join table from TRACK to MEDIA_GROUP which is 1:1 and MEDIA has a FK column into MEDIA_GROUP. I'm trying to find a way in hibernate to map a collection of Media directly into the Track object, bypassing the creation of a MediaGroup object. Basically I want to turn this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA_GROUP <-> MEDIA into this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA But the join column between MEDIA_TRACK_MAP and MEDIA isn't the primary key of MEDIA.

• [SQL] Query returning more than one row with the same name

  - by Neutralise

  I am having trouble with an SQL query returning more than one row with the same name, using this query: SELECT * FROM People P JOIN SpecialityCombo C ON P.PERSONID = C.PERSONID JOIN Speciality S ON C.GROUPID = S.ID; People contains information on each person, Specialty contains the names and ID of each specialty and SpecialityCombo contains information about the associations between People and their Speciality, namely each row has a PERSONID and a Speciality ID (trying to keep it normalised to some extent). My query works in that it returns each Person and the name of their specialty, but it returns n rows for the number of specialitys they want, because each specialty returns the same row 'name'. What I want is it to return just one row containing each speciality. How can I do this?

• SQL Server, fetching data from multiple joined tables. Why is slow?

  - by user562192

  I have problem with performance when retrieving data from SQL Server. My sql query looks something like this: SELECT table_1.id, table_1.value, table_2.id, table_2.value,..., table_20.id, table_20.value From table_1 INNER JOIN table_2 ON table_1.id = table_2.table_1_id INNER JOIN table_3 ON table_2.id = table_3.table_2_id... WHERE table_1.row_number BETWEEN 1 AND 20 So, I am fetching 20 results. This query takes about 5 seconds to execute. When I select only table_1.id, it returns results instantly. Because of that, I guess that problem is not in JOINs, it is in retrieving data from multiple tables. Any suggestions how I would speed up this query?

• Rails activerecord includes. How to access the included columns?

  - by Lee Quarella

  I my User has_many :event_patrons and EventPatron belongs_to :user. I would like to slap together the user with one specific event patron with something like this sql statement: SELECT * FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 So in rails I tried this: User.all(:joins => :event_patrons, :condidions => {:event_patrons => {:event_id => 1}}) But that gives me SELECT users.* instead of SELECT *: SELECT `users`* FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 I then tried to switch the :joins with :include and got a whole jumbled mess that still returned me only the columns in User and none from EventPatron. What am I missing?

  Well I have this - Table DimDate- Date Table Employee- Id,Name,Points,Date Now the Employee table has points for everyday unless they did not come...so the Date does not have all the Dates entries...

  I use the following query: select * from A LEFT JOIN B on ( A.t_id != B.t_id) to get all the records in A that are not in B.

• MySQL GROUP BY with three tables

  - by Psaniko

  I have the following tables: posts (post_id, content, etc) comments (comment_id, post_id, content, etc) posts_categories (post_category_id, post_id, category_id) and this query: SELECT `p`.*, COUNT(comments.comment_id) AS cmts, posts_categories.*,comments.* FROM `posts` AS `p` LEFT JOIN `posts_categories` ON `p`.post_id = `posts_categories`.post_id LEFT JOIN `comments` ON `p`.post_id = `comments`.post_id GROUP BY `p`.`post_id` There are three comments on post_id=1 and four in total. In posts_categories there are two rows, both assigned to post_id=1. I have four rows in posts. But if I query the statement above I get a result of 6 for COUNT(comments.comment_id) at post_id=1. How is this possible? I guess the mistake is somewhere in the GROUP BY clause but I can't figure out where. Any suggestions?

• MySQL: Query to obtain recipes using all given ingredients.

  - by John_A

  hi I have the following simplified tables: CREATE TABLE recipe(id int, name varchar(25)); CREATE TABLE ingredient(name varchar(25)); CREATE TABLE uses_ingredient(recipe_id int, name varchar(25)); I want to make a query that returns all id's of recipes that contain both Chicken and Cream. I have tried SELECT recipe_id FROM uses_ingredient INNER JOIN (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id) >= (SELECT COUNT(*) FROM theme); which gives me :"ERROR 1248 (42000): Every derived table must have its own alias" and is probably wrong too. Next I tried SELECT recipe_id FROM (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") AS t INNER JOIN uses_ingredient USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id)>= (SELECT COUNT(*) FROM t); which gives "ERROR 1146 (42S02): Table 'recipedb.t' doesn't exist" I want to avoid creating temporary tables including using ENGINE=MEMORY.

• Not sure how to use Decode, NVL, and/or isNull (or something else?) in this situation

  - by RSW

  I have a table of orders for particular products, and a table of products that are on sale. (It's not ideal database structure, but that's out of my control.) What I want to do is outer join the order table to the sale table via product number, but I don't want to include any particular data from the sale table, I just want a Y if the join exists or N if it doesn't in the output. Can anyone explain how I can do this in SQL? Thanks in advance!

• VS 2010 SQL Update for SQL Statement

  - by Mike Tucker

  Please bear with me as I'm just beginning to learn this stuff. I have a VS 2010 Web project up and I'm trying to understand how I can make a custom UpdateCommand (Because I chose to write my own SQL statement, I do not have the option for VS 2010 to auto generate an update command for me.) Problem is: I don't know what the UpdateCommand should look like. Here is my Select: SELECT * FROM Dbo.MainAsset, dbo.Model, dbo.Hardware WHERE MainAsset.device = Hardware.DeviceID AND MainAsset.model = Model.DeviceID Which, VS 2010 turns into: SELECT MainAsset.pk, MainAsset.img, MainAsset.device, MainAsset.model, MainAsset.os, MainAsset.asset, MainAsset.serial, MainAsset.inyear, MainAsset.expyear, MainAsset.site, MainAsset.room, MainAsset.teacher, MainAsset.FirstName, MainAsset.LastName, MainAsset.Notes, MainAsset.Dept, MainAsset.AccountingCode, Model.Model AS Hardware, Model.pk AS Model, Model.DeviceID, Hardware.Computer, Hardware.pk AS Expr3, Hardware.DeviceID AS Expr4 FROM MainAsset INNER JOIN Hardware ON MainAsset.device = Hardware.DeviceID INNER JOIN Model ON MainAsset.model = Model.DeviceID How would I approach updating one column, say "MainAsset.site" if that's changed in the Gridview DDL? Any help constructive help would be appreciated. Thank you.

• How to select random image of specific size using Django / Python?

  - by Jonathan

  I've been using this little snippet to select random images. However I would like to change it to select only images of a certain size. I'm running into trouble checking against image size. If I use get_image_dimensions() I need to use a conditional statement, which then requires that I allow exceptions. So, I guess I need some pointers on just limiting by image dimensions. Thanks. import os import random import posixpath from django import template from django.conf import settings register = template.Library() def is_image_file(filename): """Does `filename` appear to be an image file?""" img_types = [".jpg", ".jpeg", ".png", ".gif"] ext = os.path.splitext(filename)[1] return ext in img_types @register.simple_tag def random_image(path): """ Select a random image file from the provided directory and return its href. `path` should be relative to MEDIA_ROOT.

• How to map one class against multiple tables with SQLAlchemy?

  - by tote

  Lets say that I have a database structure with three tables that look like this: items - item_id - item_handle attributes - attribute_id - attribute_name item_attributes - item_attribute_id - item_id - attribute_id - attribute_value I would like to be able to do this in SQLAlchemy: item = Item('item1') item.foo = 'bar' session.add(item) session.commit() item1 = session.query(Item).filter_by(handle='item1').one() print item1.foo # => 'bar' I'm new to SQLAlchemy and I found this in the documentation (http://www.sqlalchemy.org/docs/05/mappers.html#mapping-a-class-against-multiple-tables): j = join(items, item_attributes, items.c.item_id == item_attributes.c.item_id). \ join(attributes, item_attributes.c.attribute_id == attributes.c.attribute_id) mapper(Item, j, properties={ 'item_id': [items.c.item_id, item_attributes.c.item_id], 'attribute_id': [item_attributes.c.attribute_id, attributes.c.attribute_id], }) It only adds item_id and attribute_id to Item and its not possible to add attributes to Item object. Is what I'm trying to achieve possible with SQLAlchemy? Is there a better way to structure the database to get the same behaviour of "dynamic columns"?

• AS or not to AS, queries

  - by zeMinimalist

  I'm fairly new to PHP/MySql and using queries in general. I was just wondering if there's any benefit to using "AS" in a query other than trying to make it look cleaner? Does it speed up the query at all? I probably could have figured this out by a google search but I wanted to ask my first question and see how this works. I WILL select an answer (unlike some people...) with: SELECT news.id as id news.name as name FROM news without: SELECT news.id news.name FROM news A more complex example from a many-to-many relationship tutorial I found: SELECT c.name, cf.title FROM celebrities AS c JOIN ( SELECT icf.c_id, icf.f_id, f.title FROM int_cf AS icf JOIN films AS f ON icf.f_id = f.f_id ) AS cf ON c.c_id = cf.c_id ORDER BY c.c_id ASC
