• Fill data gaps - UNION, PARTITION BY, or JOIN?

  - by Dave Jarvis

  Problem There are data gaps that need to be filled. Would like to avoid UNION or PARTITION BY if possible. Query Statement The select statement reads as follows: SELECT count( r.incident_id ) AS incident_tally, r.severity_cd, r.incident_typ_cd FROM report_vw r GROUP BY r.severity_cd, r.incident_typ_cd ORDER BY r.severity_cd, r.incident_typ_cd Data Sources The severity codes and incident type codes are from: severity_vw incident_type_vw The columns are: incident_tally severity_cd incident_typ_cd Actual Result Data 36 0 ENVIRONMENT 1 1 DISASTER 27 1 ENVIRONMENT 4 2 SAFETY 1 3 SAFETY Required Result Data 36 0 ENVIRONMENT 0 0 DISASTER 0 0 SAFETY 27 1 ENVIRONMENT 0 1 DISASTER 0 1 SAFETY 0 2 ENVIRONMENT 0 2 DISASTER 4 2 SAFETY 0 3 ENVIRONMENT 0 3 DISASTER 1 3 SAFETY Question How would you use UNION, PARTITION BY, or LEFT JOIN to fill in the zero counts?

• JPA and aggregate functions. How do I use the result of the query?

  - by Bogdan

  Hey guys, I'm new to ORM stuff and I need some help understanding something. Let's assume I have the following standard SQL query: SELECT *, COUNT(test.testId) AS noTests FROM inspection LEFT JOIN test ON inspection.inspId = test.inspId GROUP BY inspection.inspId which I want to use in JPA. I have an Inspection entity with a one-to-many relationship to a Test entity. (an inspection has many tests) I tried writing this in JPQL: Query query = em.createQuery("SELECT insp, COUNT(???what???) FROM Inspection insp LEFT JOIN insp.testList " + "GROUP BY insp.inspId"); 1) How do I write the COUNT clause? I'd have to apply count to elements from the test table but testList is a collection, so I can't do smth like COUNT(insp.testList.testId) 2) Assuming 1 is resolved, what type of object will be returned. It will definitely not be an Inspection object... How do I use the result?

• Paginating with SQL ROW_NUMBER

  - by Kelsey Thorpe

  I want to return search results in paginated format. However I can't seem to successfully get the first 10 results of my query. The problem is the 'RowNum' returned are like 405, 687, 1024 etc. I want them to be renumbered as 1,2,3,4,5 etc., so that when I specify between rows 1 and 20 i get the first 20 search results. Instead, because the numbers are larger, I get no results between 1 and 10. If i change RowNum condition to: AND RowNum < 20000 I get plenty of results Here's the sql: SELECT * FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY DocumentID ) AS RowNum, * FROM Table ) AS RowConstrainedResult WHERE RowNum >= 1 AND RowNum < 20 AND Title LIKE '%diabetes%' AND Title LIKE '%risk%' Any help appreciated.

• 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) .

• Float as DateTime

  - by lp1

  SQL Server 2008 I almost have, I think, what I'm looking to do. I'm just trying to fine tune the result. I have a table that stores timestamps of all transactions that occur on the system. I'm writing a query to give an average transaction time. This is what I have so far: With TransTime AS ( select endtime-starttime AS Totaltime from transactiontime where starttime > '2010-05-12' and endtime < '2010-05-13') Select CAST(AVG(CAST(TotalTime As Float))As Datetime) from TransTime I'm getting the following result: 1900-01-01 00:00:00.007 I can't figure out how to strip the date off and just display the time, 00:00:00:007. Any help would be appreciated. Thank you.

• Problems inserting file data into sqlite database using python

  - by tylerc230

  I'm trying to open an image file in python and add that data to an sqlite table. I created the table using: "CREATE TABLE "images" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL , "description" VARCHAR, "image" BLOB );" I am trying to add the image to the db using: imageFile = open(imageName, 'rb') b = sqlite3.Binary(imageFile.read()) targetCursor.execute("INSERT INTO images (image) values(?)", (b,)) targetCursor.execute("SELECT id from images") for id in targetCursor: imageid= id[0] targetCursor.execute("INSERT INTO %s (questionID,imageID) values(?,?)" % table, (questionId, imageid)) When I print the value of 'b' it looks like binary data but when I call: 'select image from images where id = 1' I get '????' printed to the console. Anyone know what I'm doing wrong?

• How do I make my MySQL query with joins more concise?

  - by John Hoffman

  I have a huge MySQL query that depends on JOINs. SELECT m.id, l.name as location, CONCAT(u.firstName, " ", u.lastName) AS matchee, u.email AS mEmail, u.description AS description, m.time AS meetingTime FROM matches AS m LEFT JOIN locations AS l ON locationID=l.id LEFT JOIN users AS u ON (u.id=m.user1ID) WHERE m.user2ID=2 UNION SELECT m.id, l.name as location, CONCAT(u.firstName, " ", u.lastName) AS matchee, u.email AS mEmail, u.description AS description, m.time AS meetingTime FROM matches AS m LEFT JOIN locations AS l ON locationID=l.id LEFT JOIN users AS u ON (u.id=m.user2ID) WHERE m.user1ID=2 The first 3 lines of each sub-statement divided by UNION are identical. How can I abide by the DRY principle, not repeat those three lines, and make this query more concise?

• Android use of an string array on another method

  - by spagi

  Hi all. Im trying to make an activity that has a multiple choice dialog after you push a button. In there you select from a list of things. But these things are received from a web method before the dialog appears. So I create a string array after I receive them inside the onCreate to initialise it there with the correct size. But my dialog method then cant get the array because propably its out of its scope. My code looks like this @Override protected Dialog onCreateDialog(int id) //Here is where the array is loaded to the multiple select dialog etc @Override public void onCreate(Bundle savedInstanceState) //Here is where i initialise the array and get its contents etc I cant initialise my array when the class starts because I dont know its size yet. This has to do something with the scopes of my variables and I am pretty confused

• Limit child rows in Entity Framework Query

  - by Jim

  Hi, If I have a parent and child modelled relationship. How to I select the parent, and some of the child rows. I cannot seem to do it, and load the parent object. var query = ( from parent in Parents.Include("Children") from child in parent.Children where child.Date == parent.Children.Max(x => x.Date) select parent); the problem is that the parent is returned multiple times, not the parent with the children loaded. Is there any way to populate each of the parents, and include the child rows, but only the ones needed. If I try and navigate again, I get all the children, not just the ones with the latest date. Thanks

• Approach to data wrapping

  - by Mikhail

  I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?

• MySQL - Selecting the top occurring entries

  - by RC

  Hi, Should be a simple one. Database is mydb. One of the columns is mydata. What SELECT query do I need in order to select the top 3 occurring results from mydata, but sorted alphabetically? For example, if my data is this: mydata ====== kilo (x 1 occurrence) lima (x 9 occurrences) golf (x 5 occurrences) echo (x 9 occurrences) zulu (x 8 occurrences) How do I get it to return "echo, lima, zulu", which are the top three frequently occurring entries sorted alphabetically? Thanks! EDIT: Just to add, they need to be distinct entries. Thanks!

• Hibernate is performing unwanted SELECTs on call to saveOrUpdate

  - by digiarnie

  Let's say I have a House entity which maps to many Person entities. I then load an existing House which has 20 occupants. beginTransaction(); House house = houseDao.find(1L); commitTransaction(); Later in the code, I can then add a new Person to the House: ... List<Person> people = house.getPeople(); people.add(new Person("Dilbert")); .... When I make the call: session.saveOrUpdate(house); Hibernate performs 21 queries: 1 to SELECT the House and 20 to SELECT each existing Person in the House. I'm sure it's a small issue on my part, however, what should I do so that I can add a new Person to the house without having such a heavy hit on the database in this situation? This is all done within the same session.

• DataGridView: can you add an unbound column to a Data Bound grid?

  - by Jack Johnstone

  I´m using Visual Studio 2008, C# DataGridView: can you add an unbound column to a Data Bound grid? It seems pretty simple, just select the properties ("DataGridView Tasks box") for the data bound DataGridView, and select Add unbound column. However, when in runtime there will be a System.FormatException - which I can understand, as I don´t know how to "initialize" the cells in the new unbound columns. I was planning initializing it programmatically via CellFormatting event - but so far I´m failing. Any tips? Just want to get it up and running in SOME way...

• Access 2007: Dynamic SQL to be run when opening a report

  - by blockcipher

  I'm trying to have some SQL execute when I open a report. This works fine when I try to match on a column that's an integer with an integer, but when I try to match on a "text" column, it keeps popping up a dialog asking for what you want to filter on. Here's a somple query: select person_phone_numbers.person_id from person_phone_numbers where phone_number = '444-444-4444' This is actually a sub-query I'm trying to use, but this is where the problem is. If I change it to this it works fine: select person_phone_numbers.person_id from person_phone_numbers where phone_id = 2 I put this in the OnOpen event and I'm assigning it to Me.RecordSource if that makes a difference. My goal here is to have a form accept query parameter(s) and have it open a report with the results. Any thoughts on why it wants to ask for a parameter vs. just running the query the way I have it?

• SQL Server 2005 Weird varchar Behavior

What is up with @Test1? Could someone please explain this behavior?

• Recursive CTE with alternating tables

  - by SOfanatic

  I've created a SQL fiddle here. Basically, I have 3 tables BaseTable, Files, and a LinkingTable. The Files table has 3 columns: PK, BaseTableId, RecursiveId (ChildId). What I want to do is find all the children given a BaseTableId (i.e., ParentId). The tricky part is that the way the children are found works like this: Take ParentId 1 and use that to look up a FileId in the Files table, then use that FileId to look for a ChildId in the LinkingTable, if that record exists then use the RecursiveId in the LinkingTable to look for the next FileId in the Files table and so on. This is my CTE so far: with CTE as ( select lt.FileId, lt.RecursiveId, 0 as [level], bt.BaseTableId from BaseTable bt join Files f on bt.BaseTableId = f.BaseTableId join LinkingTable lt on f.FileId = lt.FileId where bt.BaseTableId = @Id UNION ALL select rlt.FileId, rlt.RecursiveId, [level] + 1 as [level], CTE.BaseTableId from CTE --??? and this is where I get lost ... ) A correct output for BaseTableId = 1, should be: FileId|RecursiveId|level|BaseTableId 1 1 0 1 3 2 1 1 4 3 2 1

• EXCEL - Locking a Cell from User input whilst allowing a Linked combobox?

  - by Christopher Leach

  I have a Protected Worksheet which is a checklist with a series of checkpoints. Each row has Item and Description cells that are locked. Each row has several columns with its contents to be set by a ComboBox and a text input column. Both i have left unlocked. I have Locked the the Item and Description columns and left only the 'Select Unlocked Cells' checked via Sheet Protection. I have one ComboBox on the worksheet that moves around and adjusts its LinkedCell and its Content list using the worksheets SelectionChanged event. When the user selects a cell to bring up the drop down list, the user is able to type into the cell and the Drop Down Box disappears. What is the best way to keep the cell unlocked so it can be selectable(as 'Select Locked Cells" is unchecked) however stop the user from being able to type in the cell and to allow the cells contents to become modifiable only via the ComboBox?

• Query a Hibernate many-to-many association

  - by Perry Hoekstra

  In Hibernate HQL, how would you query through a many-to-many association. If I have a Company with multiple ProductLines and other companies can offer these same product lines, I have a Company entity, a ProductLine entity and an association table CompanyProductLine. In SQL, I can get what I need like this: select * from company c where c.companyId in (select companyId from companyProductLine cpl, productline pl where cpl.productLineId = pl.productLineId and pl.name= 'some value'); My problem sees to lie with the association I defined in the Company.hbm.xml file: <set name="productLines" cascade="save-update" table="CompanyProductLine"> <key column="companyId"/> <many-to-many class="com.foo.ProductLine" column="productLineId" /> </set> Any HQL I seem to come up with will throw a: 'expecting 'elements' or 'indices"' Hibernate exception. Thoughts on what the proper HQL would be?
