  • MySQL Column Value Pivot

    - by manyxcxi
    I have a MySQL InnoDB table laid out like so: id (int), run_id (int), element_name (varchar), value (text), line_order, column_order `MyDB`.`MyTable` ( `id` bigint(20) NOT NULL, `run_id` int(11) NOT NULL, `element_name` varchar(255) NOT NULL, `value` text, `line_order` int(11) default NULL, `column_order` int(11) default NULL It is used to store data generated by a Java program that used to output this in CSV format, hence the line_order and column_order. Lets say I have 2 entries (according to the table description): 1,1,'ELEMENT 1','A',0,0 2,1,'ELEMENT 2','B',0,1 I want to pivot this data in a view for reporting so that it would look like more like the CSV would, where the output would look this: --------------------- |ELEMENT 1|ELEMENT 2| --------------------- | A | B | --------------------- The data coming in is extremely dynamic; it can be in any order, can be any of over 900 different elements, and the value could be anything. The Run ID ties them all together, and the line and column order basically let me know where the user wants that data to come back in order.

  • LaTeX: Automatic two-column wrapping of content

    - by plash
    Say I have a list of words that need to retain their order, and need to be sorted into two columns. I can do this rather well with a tabular: \begin{tabular}{l l} abc & def \\ ghi & jkl \\ \end{tabular} But doing so makes it rather difficult and time consuming to reorder the list. Is it possible to have an automatically wrapped two-column list? Ideally, I would like to simply enter an ordered list: \begin{magic} abc \\ def \\ ghi \\ jkl \\ \end{magic} And have it wrapped to two columns (as the tabular enables): abc def ghi jkl

  • Querying a Single Column with LINQ

    - by Hossein Margani
    Hi Every one! I want to fetch array of values of a single column in a table, for example, I have a table named Customer(ID,Name), and want to fetch ids of all customers. my query in LINQ is: var ids = db.Customers.Select(c=>c.ID).ToList(); The answer of this query is correct, but I ran SQL Server Profiler, and saw the query which was like this: SELECT [t0].[ID], [t0].[Name] FROM [dbo].[Customer] AS [t0] I understood that LINQ selects all columns and then creates the integer array of ID fields. How can I write a LINQ query which generates this query in SQL Server: SELECT [t0].[ID] FROM [dbo].[Customer] AS [t0] Thank you.

  • Index on column with only 2 distinct values

    - by Will
    I am wondering about the performance of this index: I have an "Invalid" varchar(1) column that has 2 values: NULL or 'Y' I have an index on (invalid), as well as (invalid, last_validated) Last_validated is a datetime (this is used for a unrelated SELECT query) I am flagging a small amount of items (1-5%) of rows in the table with this as 'to be deleted'. This is so when i DELETE FROM items WHERE invalid='Y' it does not perform a full table scan for the invalid items. A problem seems to be, the actual DELETE is quite slow now, possibly because all the indexes are being removed as they are deleted. Would a bitmap index provide better performance for this? or perhaps no index at all?

  • Swap unique indexed column values in database.

    - by Ramesh Soni
    I have a database table and one of the fields (not primary key) is having unique index on it. Now I want to swap values under this column for two rows. How could this be done? Two hack I know are: Delete both rows and re-insert them Update rows with some other value and swap and then update to actual value. But I don't want to go for these as they do not seem to be the appropriate solution to the problem. Could anyone help me out?

  • MySQL Insert not working with Date column

    - by Ian McCullough
    Hello All, I am having an issue with a simple insert query into a table. I have this PHP Code $T_MEMBER = "INSERT INTO T_MEMBER (MEMBER_IDENTIFIER,LAST_NAME,FIRST_NAME,BIRTH_DATE) VALUES ('$memberID','$last','$first','$birthdate')"; mysql_query($T_MEMBER) or die(mysql_error()); Here are a few examples of what the query looks like if i echo it: INSERT INTO T_MEMBER (MEMBER_IDENTIFIER,LAST_NAME,FIRST_NAME,BIRTH_DATE) VALUES ('2007','Hayes','Karin','1958-30-10') INSERT INTO T_MEMBER (MEMBER_IDENTIFIER,LAST_NAME,FIRST_NAME,BIRTH_DATE) VALUES ('2020','Long','Peggy','1968-29-5') INSERT INTO T_MEMBER (MEMBER_IDENTIFIER,LAST_NAME,FIRST_NAME,BIRTH_DATE) VALUES ('2021','Torres','Diane','1968-30-8') BIRTH_DATE is a date type column. The problem is, after i do any of these queries, the date shows up as 000-00-00!!!! I have been wracking my brain and i cannot seem to find the issue. Thanks, Ian

  • Reversing column values in mysql command line

    - by user94154
    I have a table posts with the column published, which is either 0 (unpublished) or 1 (published). Say I want to make all the published posts into unpublished posts and all the unpublished posts into published posts. I know that running UPDATE posts SET published = 1 WHERE published = 0; UPDATE posts SET published = 0 WHERE published = 1; will end up turning all my posts into published posts. How can I run these queries in the mysql command line so that it truly "reverse" the values, as opposed to the mistake outlined above? Thanks

  • wpf style converter : "Convert" called by every datagrid column using it

    - by Sonic Soul
    I created a converter, and assigned it to a style. than i assigned that style, to the columns i want affected. as rows are added, and while stepping through debugger, i noticed that the converter convert method gets called 1 time per column (each time it is used). is there a way to optimize it better, so that it gets called only once and all columns using it get the same value? <Style x:Key="ConditionalColorStyle" TargetType="{x:Type DataGridCell}" BasedOn="{StaticResource CellStyle}"> <Setter Property="Foreground"> <Setter.Value> <Binding> <Binding.Converter> <local:ConditionalColorConverter /> </Binding.Converter> </Binding> </Setter.Value> </Setter> </Style>

  • Oracle - Updating one column or another based on a condition

    - by z-dan
    I want to update a record in a table but based on a condition I will either update one column or another but I do not want to have 2 separate statements because the statements are very long and detailed. Here is the basic idea with over simplification to get to the point. PROCEDURE Animal_something(p_updater VARCHAR2) begin if p_updater = 'person' then -- I want to update the modified_by else -- if p_updater = 'a process' I want to update modified_by_process Update table_creatures set animal_type = 'Dog , **modified_by** = 'Bob' **or do this** **modified_by_process =** 'creature_package' where animal_legs = '4' I don't want: if p_updater = 'person' then Update table_creatures set animal_type = 'Dog , modified_by = 'Bob' where animal_legs = '4'; else Update table_creatures set animal_type = 'Dog , modified_by_process = 'creature_package' where animal_legs = '4'; end;

  • How to select only the first rows for each unique value of a column

    - by nuit9
    Let's say I have a table of customer addresses: CName | AddressLine ------------------------------- John Smith | 123 Nowheresville Jane Doe | 456 Evergreen Terrace John Smith | 999 Somewhereelse Joe Bloggs | 1 Second Ave In the table, one customer like John Smith can have multiple addresses. I need the select query for this table to return only first row found where there are duplicates in 'CName'. For this table it should return all rows except the 3rd (or 1st - any of those two addresses are okay but only one can be returned). Is there a keyword I can add to the SELECT query to filter based on whether the server has already seen the column value before?

  • wrapping the content of a span inside an li so it stays in its own column

    - by codergeek
    hello, I have a list, each li in it has this structure: <li> <img class="yes" src="..."> <img class="no" src="..."> <span class="a">...</span> <span class="b">...</span> </li> now if the content of class b is long, it will wrap around the image. I don't want it to wrap under the image, I want it to stay in its own column. If there is anyway to do this, please let me know as using tables to do it will be just wrong. Thanks! Nima

  • How to change the order of toolbar buttons in Internet Explorer?

    - by Rick
    I know I can simply write to the CommandBandLayout regkey but since I don't know what format it is I'm having doubts if that is safe. Also, this answer suggest it's the wrong solution: http://stackoverflow.com/questions/1239266/how-to-modify-commandbandlayout-reg-key-value But how can I change the order a bit? I have written an Internet Explorer Add-on and I've registered it by putting it in HKCU but by default it falls off the screen so users are having trouble finding it. I would like to make the bar wider or move the button back in the screen.

  • Add keyframes to a stream (FLV from RTMP)

    - by acidzombie24
    I downloaded a RTMP stream to my desktop. It uses the FLV (Flash) video codec. I do not want to reprocess/transcode/whatever to this video. VirtualDub can delete sections of video and since it's not encoding again the quality is the same and the filesize shrinks. I want to do something similar but instead add keyframes and not encode. What can I use?

  • datagrid column custom check mark

    - by Berryl
    I want a read only column bound to a boolean that shows a check mark image when true and nothing when false. The problem is the false value; I just want to show whatever the background of the datagrid is, but I don't see how to clear the image source. What should the Value of the image source be to do this? Cheers, Berryl <DataGridTemplateColumn.CellTemplate> <DataTemplate> <Image Name="imgChecked" Source="\Img_Checkmark" /> <DataTemplate.Triggers> <DataTrigger Binding="{Binding IsPrimary}" Value="False"> <Setter TargetName="imgChecked" Property="Source" Value=""/> *** ??? *** </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </DataGridTemplateColumn.CellTemplate>

  • MySQL: Column Contains Word From List of Words

    - by mellowsoon
    I have a list of words. Lets say they are 'Apple', 'Orange', and 'Pear'. I have rows in the database like this: ------------------------------------------------ |author_id | content | ------------------------------------------------ | 54 | I ate an apple for breakfast. | | 63 | Going to the store. | | 12 | Should I wear the orange shirt? | ------------------------------------------------ I'm looking for a query on an InnoDB table that will return the 1st and 3rd row, because the content column contains one or more words from my list. I know I could query the table once for each word in my list, and use LIKE and the % wildcard character, but I'm wondering if there is a single query method for such a thing?

  • cfgrid boolean column as Yes/No

    - by Gene R
    I have a boolean type column in an html cfgrid. The data is stored in the database as 1/0 and is returned from CF as such. I want the user to see Yes/No instead of 1/0. I tried QuerySetCell, and couldn't get it to work. The form is editable, when you double click the cell, the checkboxes show and it updates as it should. The only issue is the display. <cfform> <cfgrid name="blah" format="html" bind="mycfccall" selectmode="edit"> <cfgridcolumn name="bitCol" header="Is it" width="75" type="boolean"> </cfgrid> </cfform> Thanks in advance...

  • Grails multi column indexes

    - by Kimble
    Can someone explain how to define multi column indexes in Grails? The documentation is at best sparse. This for example does not seem to work at all: http://grails.org/GORM+Index+definitions I've had some luck with this, but the results seems random at best. Definitions that works in one domain class does not when applied to another (with different names of course). http://www.grails.org/doc/1.1/guide/single.html#5.5.2.6%20Database%20Indices Some working examples and explanations would be highly appreciated!
