  • MDX Filter a dimention with another dimension

    - by John Hartsock
    To all excuse my ignorance, but im new to MDX below is the query im trying to run SELECT NON EMPTY { [Measures].[Task Burn Down] } ON COLUMNS, NON EMPTY { ([Calendar].[Date].[Date].ALLMEMBERS * [Priority].[Priority Code].[Priority Code].ALLMEMBERS ) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( { Filter([Calendar].[Date].AllMembers, [Calendar].[Date].CurrentMember <= [Sprint].[Sprint].CurrentMember.Properties("Stop Date")) } ) ON COLUMNS FROM ( SELECT ( { [Sprint].[Sprint].AllMembers } ) ON COLUMNS FROM ( SELECT ( { [Team].[Team].AllMembers } ) ON COLUMNS FROM [Backlog2] ) ) ) WHERE ( [Team].[Team].&[27], [Sprint].[Sprint].&[9] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS When I run this I expect to get 1 value for [Measures].[Task Burn Down] for each day of the month. But I only want one month. My Sprint dimension has a stop date and I do not want to return any values after the stop date. What am I doing wrong?

  • Can't figure out how to list all the people that don't live in same City as...

    - by AspOnMyNet
    I’d like to list all the people ( Person table ) that don’t live in same city as those cities listed in Location table. Thus, if Location table holds a record with City=’New York’ and State=’Moon’, but Person table holds a record with FirstName=’Someone’, City=’New York’ and Location=’Mars’, then Someone is listed in the resulting set, since she lives in New York located on Mars and not New York located on Moon, thus we’re talking about different cities with the same name. I tried solving it with the following query, but results are wrong: SELECT Person.FirstName, Person.LastName, Person.City, Person.State FROM Person INNER JOIN Location ON (Person.City <> Location.City AND Person.State = Location.State) OR (Person.City = Location.City AND Person.State <> Location.State) OR (Person.City <> Location.City AND Person.State <> Location.State) ORDER BY Person.LastName; Any ideas?

  • why custom state won't work with compound drawable?

    - by schwiz
    Hello I am trying to make a password registration widget that will show a little checkbox in the textbox when both password boxes match. I decided to go about this by extending EditText to implement a valid and an empty state and then just use a state-list drawable to handle everything else. I followed the same method that the CompoundButton uses to add a custom state and everything seems to be right but the image will never change no matter what the state is (custom state or even state_focused etc) Is there some reason that the compound drawables of a TextView wouldn't work as a state-list drawable? Or, am I doing something wrong? Here is attrs.xml <resources> <declare-styleable name="ValidyState"> <attr name="state_valid" format="boolean"/> <attr name="state_has_text" format="boolean"/> </declare-styleable> </resources> my selector <selector xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res/com.schwiz.test"> <item android:drawable="@drawable/emptyspace" app:state_has_text="false"/> <item android:drawable="@drawable/ic_valid" app:state_valid="true" app:state_has_text="true"/> <item android:drawable="@drawable/ic_invalid" app:state_valid="false" app:state_has_text="true"/> </selector> and in my overridden EditText class private static final int[] VALID_STATE_SET = { R.attr.state_valid }; private static final int[] HASTEXT_STATE_SET = { R.attr.state_has_text }; ... private void refreshDrawables(){ Drawable[] drawables = getCompoundDrawables(); for(int i = 0; i < drawables.length; i++){ if(drawables[i] != null) { drawables[i].setState(getDrawableState()); } } invalidate(); } @Override protected void drawableStateChanged() { super.drawableStateChanged(); refreshDrawables(); } @Override protected int[] onCreateDrawableState(int extraSpace) { final int[] drawableState = super.onCreateDrawableState(extraSpace + 2); if(hasText){ mergeDrawableStates(drawableState, HASTEXT_STATE_SET); } if(isValid){ mergeDrawableStates(drawableState, VALID_STATE_SET); } return drawableState; }

  • Efficient way to update SQL 'relationship' table

    - by AmbroseChapel
    Say I have three properly normalised tables. One of people, one of qualifications and one mapping people to qualifications: People: id | Name ---------- 1 | Alice 2 | Bob Degrees: id | Name --------- 1 | PhD 2 | MA People-to-degrees: person_id | degree_id --------------------- 1 | 2 # Alice has an MA 2 | 1 # Bob has a PhD So then I have to update this mapping via my web interface. (I made a mistake. Bob has a BA, not a PhD, and Alice just got her B Eng.) There are four possible states of these one-to-many relationship mappings: was true before, should now be false was false before, should now be true was true before, should remain true was false before, should remain false what I don't want to do is read the values from four checkboxes, then hit the database four times to say "Did Bob have a BA before? Well he does now." "Did Bob have PhD before? Because he doesn't any more" and so on. How do other people address this issue? I'm curious to see if someone else arrives at the same solution I did.

  • Saving and retrieving image in SQL database from C# problem

    - by Mobin
    I used this code for inserting records in a person table in my DB System.IO.MemoryStream ms = new System.IO.MemoryStream(); Image img = Image_Box.Image; img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); this.personTableAdapter1.Insert(NIC_Box.Text.Trim(), Application_Box.Text.Trim(), Name_Box.Text.Trim(), Father_Name_Box.Text.Trim(), DOB_TimePicker.Value.Date, Address_Box.Text.Trim(), City_Box.Text.Trim(), Country_Box.Text.Trim(), ms.GetBuffer()); but when i retrieve this with this code byte[] image = (byte[])Person_On_Application.Rows[0][8]; MemoryStream Stream = new MemoryStream(); Stream.Write(image, 0, image.Length); Bitmap Display_Picture = new Bitmap(Stream); Image_Box.Image = Display_Picture; it works perfectly fine but if i update this with my own generated Query like System.IO.MemoryStream ms = new System.IO.MemoryStream(); Image img = Image_Box.Image; img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); Query = "UPDATE Person SET Person_Image ='"+ms.GetBuffer()+"' WHERE (Person_NIC = '"+NIC_Box.Text.Trim()+"')"; the next time i use the same code for retrieving the image and displaying it as used above . Program throws an exception

  • What is the mysql 5.5 equivalent for the sys.dm_fts_index_keywords_by_document in sql 2008

    - by djsurge
    I'm making a web application that uses the data in the sys.dm_fts_index_keywords_by_document. I'm interested how many times a given term occurs in each string that is indexed. For example, I have a table with a column called comments, the table has various strings in the comments field. When I make that column full text searchable, the dm_fts_index_keywords_by_document is created and I can see the word per document data. Can i do the same thing in mySQL?

  • syntax for single row MERGE / upsert in SQL Server

    - by Jacob
    I'm trying to do a single row insert/update on a table but all the examples out there are for sets. Can anyone fix my syntax please: MERGE member_topic ON mt_member = 0 AND mt_topic = 110 WHEN MATCHED THEN UPDATE SET mt_notes = 'test' WHEN NOT MATCHED THEN INSERT (mt_member, mt_topic, mt_notes) VALUES (0, 110, 'test') Resolution per marc_s is to convert the single row to a subquery - which makes me think the MERGE command is not really intended for single row upserts. MERGE member_topic USING (SELECT 0 mt_member, 110 mt_topic) as source ON member_topic.mt_member = source.mt_member AND member_topic.mt_topic = source.mt_topic WHEN MATCHED THEN UPDATE SET mt_notes = 'test' WHEN NOT MATCHED THEN INSERT (mt_member, mt_topic, mt_notes) VALUES (0, 110, 'test');

  • More FP-correct way to create an update sql query

    - by James Black
    I am working on access a database using F# and my initial attempt at creating a function to create the update query is flawed. let BuildUserUpdateQuery (oldUser:UserType) (newUser:UserType) = let buf = new System.Text.StringBuilder("UPDATE users SET "); if (oldUser.FirstName.Equals(newUser.FirstName) = false) then buf.Append("SET first_name='").Append(newUser.FirstName).Append("'" ) |> ignore if (oldUser.LastName.Equals(newUser.LastName) = false) then buf.Append("SET last_name='").Append(newUser.LastName).Append("'" ) |> ignore if (oldUser.UserName.Equals(newUser.UserName) = false) then buf.Append("SET username='").Append(newUser.UserName).Append("'" ) |> ignore buf.Append(" WHERE id=").Append(newUser.Id).ToString() This doesn't properly put a , between any update parts after the first, for example: UPDATE users SET first_name='Firstname', last_name='lastname' WHERE id=... I could put in a mutable variable to keep track when the first part of the set clause is appended, but that seems wrong. I could just create an list of tuples, where each tuple is oldtext, newtext, columnname, so that I could then loop through the list and build up the query, but it seems that I should be passing in a StringBuilder to a recursive function, returning back a boolean which is then passed as a parameter to the recursive function. Does this seem to be the best approach, or is there a better one?

  • SQL count NULL cells

    - by Giuseppe
    Dear All, I have the following problem. I have a table in a db, with many columns. I can do different kind of select queries, to show, for example, for each record that satisfies a condition: all cells from columns with names ending in _t0 all cells from columns with names ending in _t1 ... To get the column lists to form the queries I use the information schema. Now, the problem: each query returns a record with a subset of the columns of the big table. This means that I can get a row of (all!) NULLs. How can I ask my query to reject such rows without having to type in explicitely the column names (i.e. by saying where col_1 is not null, col_2 is not null...)? Is it possible? Thanks in advance!!!

  • How to combine two sql queries?

    - by plasmuska
    Hi Guys, I have a stock table and I would like to create a report that will show how often were items ordered. "stock" table: item_id | pcs | operation apples | 100 | order oranges | 50 | order apples | -100 | delivery pears | 100 | order oranges | -40 | delivery apples | 50 | order apples | 50 | delivery Basically I need to join these two queries together. A query which prints stock balances: SELECT stock.item_id, Sum(stock.pcs) AS stock_balance FROM stock GROUP BY stock.item_id; A query which prints sales statistics SELECT stock.item_id, Sum(stock.pcs) AS pcs_ordered, Count(stock.item_id) AS number_of_orders FROM stock GROUP BY stock.item_id, stock.operation HAVING stock.operation="order"; I think that some sort of JOIN would do the job but I have no idea how to glue queries together. Desired output: item_id | stock_balance | pcs_ordered | number_of_orders apples | 0 | 150 | 2 oranges | 10 | 50 | 1 pears | 100 | 100 | 1 This is just example. Maybe, I will need to add more conditions because there is more columns. Is there a universal technique of combining multiple queries together?

  • What does MSSQL execution plan show?

    - by tim
    There is the following code: declare @XmlData xml = '<Locations> <Location rid="1"/> </Locations>' declare @LocationList table (RID char(32)); insert into @LocationList(RID) select Location.RID.value('@rid','CHAR(32)') from @XmlData.nodes('/Locations/Location') Location(RID) insert into @LocationList(RID) select A2RID from tblCdbA2 Table tblCdbA2 has 172810 rows. I have executed the batch in SSMS with “Include Actual execution plan “ and having Profiler running. The plan shows that the first query cost is 88% relative to the batch and the second is 12%, but the profiler says that durations of the first and second query are 17ms and 210 ms respectively, the overall time is 229, which is not 12 and 88.. What is going on? Is there a way how I can determine in the execution plan which is the slowest part of the query?

  • Counting consecutive items within MS SQL

    - by Greg
    Got a problem with a query I'm trying to write. I have a table that lists people that have been sent an email. There is a bit column named Active which is set to true if they have responded. But I need to count the number of consecutive emails the person has been inactive since either their first email or last active email. For example, this basic table shows one person has been sent 9 emails. They have been active within two of the emails (3 & 5). So their inactive count would be 4 as we are counting from email number 6 onwards. PersonID(int) EmailID(int) Active(bit) 1 1 0 1 2 0 1 3 1 1 4 0 1 5 1 1 6 0 1 7 0 1 8 0 1 9 0 Any pointers or help would be great. Regards Greg

  • copy entire row (without knowing field names)

    - by Todd Webb
    Using SQL Server 2008, I would like to duplicate one row of a table, without knowing the field names. My key issue: as the table grows and mutates over time, I would like this copy-script to keep working, without me having to write out 30+ ever-changing fields, ugh. Also at issue, of course, is IDENTITY fields cannot be copied. My code below does work, but I wonder if there's a more appropriate method than my thrown-together text string SQL statement? So thank you in advance. Here's my (yes, working) code - I welcome suggestions on improving it. Todd alter procedure spEventCopy @EventID int as begin -- VARS... declare @SQL varchar(8000) -- LIST ALL FIELDS (*EXCLUDE* IDENTITY FIELDS). -- USE [BRACKETS] FOR ANY SILLY FIELD-NAMES WITH SPACES, OR RESERVED WORDS... select @SQL = coalesce(@SQL + ', ', '') + '[' + column_name + ']' from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'EventsTable' and COLUMNPROPERTY(OBJECT_ID('EventsTable'), COLUMN_NAME, 'IsIdentity') = 0 -- FINISH SQL COPY STATEMENT... set @SQL = 'insert into EventsTable ' + ' select ' + @SQL + ' from EventsTable ' + ' where EventID = ' + ltrim(str(@EventID)) -- COPY ROW... exec(@SQL) -- REMEMBER NEW ID... set @EventID = @@IDENTITY -- (do other stuff here) -- DONE... -- JUST FOR KICKS, RETURN THE SQL STATEMENT SO I CAN REVIEW IT IF I WISH... select EventID = @EventID, SQL = @SQL end

  • flex/actionscript client entity state refresh on JPA update using Pimento EntityManager

    - by Chris
    My Flex application uses a client-side pimento EntityManager which fetches quite a few objects and associations. It does this by forcing eager fetching of particular association ends in the form of fetch plans. I would like to update the client whenever a change has been made to an entity existing in the EntityManager's cache. Is it possible to update the state of the changed entity ONLY, including updating which entities are associated, without resetting the state of these associated entities? I have setup an EntityListener with a JPA post-update method that notifies clients when a persisted entity has been updated. I want this to trigger a refresh for the modified client-side entity, but calling EntityManager.refresh(entity) resets all lazy associations to proxies. Initializing these proxies resets the associated entities, even if they were loaded previously. I'm looking for an efficient way to keep the client's state in synch with the server's state, at least with respect to the entities that have already been retrieved by the initial load.

  • Checking inherited attributes in an 'ancestry' based SQL table

    - by Brendon Muir
    I'm using the ancestry gem to help organise my app's tree structure in the database. It basically writes a childs ancestor information to a special column called 'ancestry'. The ancestry column for a particular child might look like '1/34/87' where the parent of this child is 87, and then 87's parent is 34 and 34's is 1. It seems possible that we could select rows from this table each with a subquery that checks all the ancestors to see if a certain attribute it set. E.g. in my app you can hide an item and its children just by setting the parent element's visibility column to 0. I want to be able to find all the items where none of their ancestors are hidden. I tried converting the slashes to comma's with the REPLACE command but IN required a set of comma separated integers rather than one string with comma separated string numbers. It's funny, because I can do this query in two steps, e.g. retrieve the row, then take its ancestry column, split out the id's and make another query that checks that the id is IN that set of id's and that visibility isn't ever 0 and whala! But joining these into one query seems to be quite a task. Much searching has shown a few answers but none really do what I want. SELECT * FROM t1 WHERE id = 99; 99's ancestry column reads '1/34/87' SELECT * FROM t1 WHERE visibility = 0 AND id IN (1,34,87); kind of backwards, but if this returns no rows then the item is visible. Has anyone come across this before and come up with a solution. I don't really want to go the stored procedure route. It's for a rails app.

  • How to add Transactions with a DataSet created using the Add Connection Wizard?

    - by RoguePlanetoid
    I have a DataSet that I have added to my project where I can Insert and Add records using the Add Query function in Visual Studio 2010, however I want to add transactions to this, I have found a few examples but cannot seem to find one that works with these. I know I need to use the SQLClient.SQLTransaction Class somehow. I used the Add New Data Source Wizard and added the Tables/View/Functions I need, I just need an example using this process such as How to get the DataConnection my DataSet has used. Assuming all options have been set in the wizard and I am only using the pre-defined adapters and options asked for in this wizard, how to I add the Transaction logic to my Database. For example I have a DataSet called ProductDataSet with the XSD created for this, I have then added my Stock table as a Datasource and Added an AddStock method with a wizard, this also if a new item calls an AddItem method, if either of these fails I want to rollback the AddItem and AddStock in this case.

  • Clustered index dilemma - ID or sort?

    - by richardtallent
    I have a table with two very important fields: id INT identity(1,1) PRIMARY KEY identifiersortcode VARCHAR(900) My app always sorts and pages search results in the UI based on identifiersortcode, but all table joins (and they are legion) are on the id field. (Aside: yes, the sort code really is that long. There's a strong BL reason.) Also, due to O/RM use, most SELECT statements are going to pull almost every column. Currently, the clustered index is on id, but I'm wondering if the TOP / ORDER BY portion of most queries would make identifiersortcode a more attractive option as the clustered key, even considering all of the table joins going on. Inserts on the table and changes to the identifiersortcode are limited enough that changing my clustered index would be a problem for insert/update operations. Trying to make the sort code's non-clustered index a covering index (using INCLUDE) is not a good option. There are a number of large columns, and some of them have a lot of update activity.
