  • Sql Server problems reading columns with a foreigh key

    - by illdev
    I have a weird situation, where simple queries seem to never finish for instance SELECT top 100 ArticleID FROM Article WHERE ProductGroupID=379114 returns immediately SELECT top 1000 ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT top 1000 ArticleID FROM Article returns immediately by 'returning' I mean 'in query analyzer the green check mark appears and it says "Query executed successfully"'. I sometimes get the rows painted to the grid in qa, but still the query goes on waiting for my client to time out - 'sometimes': SELECT ProductGroupID AS Product23_1_, ArticleID AS ArticleID1_, ArticleID AS ArticleID18_0_, Inventory_Name AS Inventory3_18_0_, Inventory_UnitOfMeasure AS Inventory4_18_0_, BusinessKey AS Business5_18_0_, Name AS Name18_0_, ServesPeople AS ServesPe7_18_0_, InStock AS InStock18_0_, Description AS Descript9_18_0_, Description2 AS Descrip10_18_0_, TechnicalData AS Technic11_18_0_, IsDiscontinued AS IsDisco12_18_0_, Release AS Release18_0_, Classifications AS Classif14_18_0_, DistributorName AS Distrib15_18_0_, DistributorProductCode AS Distrib16_18_0_, Options AS Options18_0_, IsPromoted AS IsPromoted18_0_, IsBulkyFreight AS IsBulky19_18_0_, IsBackOrderOnly AS IsBackO20_18_0_, Price AS Price18_0_, Weight AS Weight18_0_, ProductGroupID AS Product23_18_0_, ConversationID AS Convers24_18_0_, DistributorID AS Distrib25_18_0_, type AS Type18_0_ FROM Article AS articles0_ WHERE (IsDiscontinued = '0') AND (ProductGroupID = 379121) shows this behavior. I have no idea what is going on. Probably select is broken ;) Anyone can tell me how to handle such a situation? More info, anyone?

  • Display another field in the referenced table for multiple columns with performance issues in mind

    - by israkir
    I have a table of edge like this: ------------------------------- | id | arg1 | relation | arg2 | ------------------------------- | 1 | 1 | 3 | 4 | ------------------------------- | 2 | 2 | 6 | 5 | ------------------------------- where arg1, relation and arg2 reference to the ids of objects in another object table: -------------------- | id | object_name | -------------------- | 1 | book | -------------------- | 2 | pen | -------------------- | 3 | on | -------------------- | 4 | table | -------------------- | 5 | bag | -------------------- | 6 | in | -------------------- What I want to do is that, considering performance issues (a very big table more than 50 million of entries) display the object_name for each edge entry rather than id such as: --------------------------- | arg1 | relation | arg2 | --------------------------- | book | on | table | --------------------------- | pen | in | bag | --------------------------- What is the best select query to do this? Also, I am open to suggestions for optimizing the query - adding more index on the tables etc... EDIT: Based on the comments below: 1) @Craig Ringer: PostgreSQL version: 8.4.13 and only index is id for both tables. 2) @andrefsp: edge is almost x2 times bigger than object.

  • mysql - combining columns and tables

    - by Phil Jackson
    Hi, I'm not much of a SQL man so I'm seeking help for this one. I have a site where I have a database for all accounts and whatnot, and another for storing actions that the user has done on the site. Each user has their own table but I want to combine the data of each user group ( all users that are "linked together" ) and order that data in the time the actions took place. Heres what I have; <?php $query = "SELECT `TALKING_TO` FROM `nnn_instant_messaging` WHERE `AUTHOR` = '" . DISPLAY_NAME . "' AND `TALKING_TO` != ''"; $query = mysql_query( $query, $CON ) or die( "_error_ " . mysql_error()); if( mysql_num_rows( $query ) != 0 ) { $table_str = ""; $select_ref_clause = "( "; $select_time_stamp_clause = "( "; while( $row = mysql_fetch_array( $query ) ) { $table_str .= "`actvbiz_networks`.`" . $row['TALKING_TO'] . "`, "; $select_ref_clause .= "`actvbiz_networks`.`" . $row['TALKING_TO'] . ".REF`, "; $select_time_stamp_clause .= "`actvbiz_networks`.`" . $row['TALKING_TO'] . ".TIME_STAMP`, "; } $table_str = $table_str . "`actvbiz_networks`.`" . DISPLAY_NAME . "`"; $select_ref_clause = substr($select_ref_clause, 0, -2) . ") AS `REF`, "; $select_time_stamp_clause = substr($select_time_stamp_clause, 0, -2) . " ) AS `TIME_STAMP`"; }else{ $table_str = "`actvbiz_networks`.`" . DISPLAY_NAME . "`"; $select_ref_clause = "`REF`, "; $select_time_stamp_clause = "`TIME_STAMP`"; } $where_clause = $select_ref_clause . $select_time_stamp_clause; $query = "SELECT " . $where_clause . " FROM " . $table_str . " ORDER BY TIME_STAMP"; die($query); $query = mysql_query( $query, $CON ) or die( "_error_ " . mysql_error()); if( mysql_num_rows( $query ) != 0 ) { }else{ ?> <p>Currently no actions have taken place in your network.</p> <?php } ?> The code above returns the sql statement: SELECT ( `actvbiz_networks`.`john_doe.REF`, `actvbiz_networks`.`Emmalene_Jackson.REF`) AS `REF`, ( `actvbiz_networks`.`john_doe.TIME_STAMP`, `actvbiz_networks`.`Emmalene_Jackson.TIME_STAMP` ) AS `TIME_STAMP` FROM `actvbiz_networks`.`john_doe`, `actvbiz_networks`.`Emmalene_Jackson`, `actvbiz_networks`.`act_web_designs` ORDER BY TIME_STAMP I really am learning on my feet with SQL. Its not the PHP I have a problem with ( I can quite happly code away with PHP ) I'ts just help with the SQL statement. Any help much appreciated, REgards, Phil

  • T-SQL Query, combine columns from multiple rows into single column

    - by Shayne
    I have seeen some examples of what I am trying to do using COALESCE and FOR XML (seems like the better solution). I just can't quite get the syntax right. Here is what I have (I will shorten the fields to only the key ones): Table Fields ------ ------------------------------- Requisition ID, Number IssuedPO ID, Number Job ID, Number Job_Activity ID, JobID (fkey) RequisitionItems ID, RequisitionID(fkey), IssuedPOID(fkey), Job_ActivityID (fkey) I need a query that will list ONE Requisition per line with its associated Jobs and IssuedPOs. (The requisition number start with "R-" and the Job Number start with "J-"). Example: R-123 | "PO1; PO2; PO3" | "J-12345; J-6780" Sure thing Adam! Here is a query that returns multiple rows. I have to use outer joins, since not all Requisitions have RequisitionItems that are assigned to Jobs and/or IssuedPOs (in that case their fkey IDs would just be null of course). SELECT DISTINCT Requisition.Number, IssuedPO.Number, Job.Number FROM Requisition INNER JOIN RequisitionItem on RequisitionItem.RequisitionID = Requisition.ID LEFT OUTER JOIN Job_Activity on RequisitionItem.JobActivityID = Job_Activity.ID LEFT OUTER JOIN Job on Job_Activity.JobID = Job.ID LEFT OUTER JOIN IssuedPO on RequisitionItem.IssuedPOID = IssuedPO.ID

  • MySQL - how to retrieve columns in same row as the values returned by min/mx

    - by Gala101
    I couldn't frame the Question's title properly.. Suppose a table of weekly movie Earnings as below, MovieName MovieGross WeekofYear Year So how do I get the names of top grossers for each week of this year If I do select MovieName , Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear; Then obviously query wont run, select Max(MovieName) , Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear; would just give movies starting with lowest alphabet Is using group-concat and then substring-index the only option here? select substring_index(group_concat(MovieName order by MovieGross desc),',',1), Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear ; Seems clumsy.. Is there any better way of acieveing this?

  • Converting rows to Columns in SQL

    - by Ram
    I have a table (actually a view, but simplified my example to a table) which gives me some data like this id CompanyName website 1 Google google.com 2 Google google.net 3 Google google.org 4 Google google.in 5 Google google.de 6 Microsoft Microsoft.com 7 Microsoft live.com 8 Microsoft bing.com 9 Microsoft hotmail.com I am looking to convert it to get a result like this CompanyName website1 website2 website3 website 4 website5 website6 ----------- ------------- ---------- ---------- ----------- --------- -------- Google google.com google.net google.org google.in google.de NULL Microsoft Microsoft.com live.com bing.com hotmail.com NULL NULL I have looked into pivot but looks like the record(row values) cannot be dynamic (i.e can only be certain predefined values). Also, if there are more than 6 websites, I want to limit it to the first 6 Dynamic pivot makes sense, but I would have to incorporate it into my view ?? Is there a simpler solution for this ? Here are the SQL scripts CREATE TABLE [dbo].[Company]( [id] [int] NULL, [CompanyName] [varchar](50) NULL, [website] [varchar](50) NULL ) ON [PRIMARY] GO insert into company values (1,'Google','google.com') insert into company values (2,'Google','google.net') insert into company values (3,'Google','google.org') insert into company values (4,'Google','google.in') insert into company values (5,'Google','google.de') insert into company values (6,'Microsoft','Microsoft.com') insert into company values (7,'Microsoft','live.com') insert into company values (8,'Microsoft','bing.com') insert into company values (9,'Microsoft','hotmail.com')

  • oracle select query - index on multiple columns

    - by CC
    Hello. I'm working on a sql query, and trying to optimise it, because it takes too long to execute. I have a few select and UNION between. Every select is on the same table but with different condition in WHERE clause. Basically I have allways something like : select * from A where field1 <"toto" and field2 IN (...) UNION select * from A where field1 >"toto2" and field2 =(...) UNION .... I have a index on field1 (it a date field, and field2 is a number). Now, when I do the select and if I put only WHERE field1 <'12/12/2010' it does not use the index. I'm using Toad to see the explain plain and it said: SELECT STAITEMENT Optimiser Mode = CHOOSE TABLE ACCESS FULL It is a huge table, and the index on this column is there. Any idea about this optimiser ? And why it does not uses the index ? Another question is , if I have where clause on field1 and field2 , I have to create only one index, or one index for each field ? Thanks alot.

  • Time diff calculations where date and time are in seperate columns

    - by pedalpete
    I've got a query where I'm trying to get the hours in duration (eg 6.5 hours) between two different times. In my database, time and date are held in different fields so I can efficiently query on just a startDate, or endDate as I never query specifically on time. My query looks like this SELECT COUNT(*), IFNULL(SUM(TIMEDIFF(endTime,startTime)),0) FROM events WHERE user=18 Sometimes an event will go overnight, so the difference between times needs to take into account the differences between the dates as well. I've been trying SELECT COUNT(*), IFNULL(SUM(TIMEDIFF(CONCAT(endDate,' ',endTime),CONCAT(startDate,' ',startTime))),0) FROM events WHERE user=18 Unfortunately I only get errors when I do this, and I can't seem to combine the two fields into a single timestamp.

  • created persisted computed columns when the user defined scalar function appears to be non-determini

    - by Ralph Shillington
    I have a scalar UDF that I know to be deterministic, however SQL doesn't. Is there a way to declare it as deterministic so that I can then use it in a persisted computed column definition? further clarification: The purpose of this exercise is that I need to harvest out specific values from an XML column on the row. I can't use the value method of the xml column in my computed column definition, but I can use it in a UDF. I know the xpath query in the value method will produce the same output give the same input so while I certainly understand that not all calls to value will be deterministic I want to assert that mine is.

  • centering ul so that columns will be centered too

    - by user1815176
    In my page I want it so that when you resize the page past the point of the pictures, that the pictures will go into another row, all the way so each picture has it's own row. And then potentially I won't need any media queries. But unfortunaltely I can't find a way to center. I have tried everything I can think of, aside of making hundreds of media queries with different positioning. I can't make it a block because then it won't go into rows, I have tried margin: 0 auto;. I have tried changing the padding, I have even tried using the html align="center". Nothing is working. Here is the website http://spencedesign.netau.net/singaporehome.html Also I have a minor issue, sorry to croud this with two questions. But when it is in it's mobile state, there is no 10px padding at the bottom, and the singapore title is on the left side rather than floating. Here is my code <html> <head> <title> Singapore - Home </title> <link rel="shortcut icon" href="favicon.ico" type="image/x-icon" /> <meta name="viewport" content="width=device-width, initial scale=1.0"> <style> * { margin: 0; padding: 0; } body { background: url('woodbackground.jpg'); background-size: cover; min-height: 100%; min-width: 100%; position: relative; top: 0; bottom: 0; left: 0; right: 0; } #container { width: 90%; margin: 0 auto; } h1 { font: bold 65px Helvetica, Arial, Sans-serif; text-align: center; color: #eee; position: relative; top: 60px; } h3 { font: 25px Helvetica, Arial, Sans-serif; text-align: center; color: #eee; position: relative; top: 80px; } ul#gallery { list-style: none; display: inline; margin: 0 auto; position: relative; top: 175px; width: 1300px; } ul#gallery li a { float: left; padding: 10px 10px 25px 10px; background-color: #eee; border: 1px solid #fff; -moz-box-shadow: 0px 2px 15px #333; position: relative; margin: 10px; text-decoration: none; } ul#gallery li a:hover { position: relative; top: -15px; } ul#gallery li a img { height: 150px; width: 250px; max-width: 100%; } ul#gallery li a p { margin-top: 25px; text-align: center; color: #000; font: Helvetica, Arial, Sans-serif; text-decoration: none; font-size: 20px; } @media screen and (max-width: 640px)    { ul#gallery {   left: 2.2%;   width: 600px; }   ul#gallery li a:hover {   top: 0px; } } </style> <body> <div id="container"> <h1> Singapore </h1> <h3><i> Singapore is the worlds first machine that works </i>- Lee Kuan Yew </h3> <ul id="gallery"> <li><a href="#"> <img src="gallery.jpg" alt="gallery" /> <p> Gallery </p> </a></li> <li><a href="#"> <img src="facts.jpg" alt="facts" /> <p> Facts </p></a></li> <li><a href="#"> <img src="tour.jpg" alt="tour" /> <p> Tour </p></a></li> <li><a href="#"> <img src="author.jpg" alt="author" /> <p> Author </p> </a></li> </ul> <br/> </div><!-- Container --> </body> <html> Thanks!

  • Wrong intrepretation of some columns in ireport

    - by Purushotham
    Hi, I got a strange problem. I am using iReport 3.7.1 tool to create some reports. The Query Editor has one query. It shows all the data types of the fields in that query exactly same as the data types shown when I execute it using SQLYOG editor. The problem is here: One field data type is mismatched. I don't know the reason. SQLYOG says it is INTEGER whereas iReport Query Editor says its a long value. BTW The value that assigned to that filed is zero. Can anyone help ? I want to zero-in on this issue.

  • Query to add a column depending of outcome of there columns

    - by Tam
    I have a user table 'users' that has fields like: id first_name last_name ... and have another table that determines relationships: user_id friend_id user_accepted friend_accepted .... I would like to generate a query that selects all the users but also add another field/column say 'network_status' that depends on the values of user_accepted and fiend_accepted. For example, if user_accepted is true friend_accepted is false I want the 'network_status' field to say 'request sent'. Can I possibly do this in one query? (I would prefer not to user if/else inside the query but if that's the only way so be it)
