  • Flex - communicating between Itemrenderes in a single row.

    - by TheCoolestSid
    Hi, I have a datagrid with an XML object as dataprovider. There are 2 columns in the datagrid which have comboboxes as their itemrenderers. The rendereriseditor property is also marked true. These itemrenderers are defined in their own mxml files. What i want is if the user selects a particular item in the combobox, say NA, then the value of the other combobox should also become NA. How can i achieve such a behavior? Thanks Sid

  • MySQL index building performance

    - by Christian
    I tried to build an index over a two columns of a 30,000,000 entry database. I canceled the process after ~60hr as it didn't seem to work. For some reason MySQL takes only 22 mb ram instead of using the RAM fully. Is index building an operation that needs no Ram or is there some way to tell MySQL to use more RAM to be faster?

  • How can I use geoalchemy with elixir autoload tables?

    - by Dan Ellis
    I'm using geoalchemy and autoloaded tables, but I'd like to use Elixir, because it has a nicer query syntax. Does anyone know how to get them to work together? I did get it working with this code -- http://pastie.textmate.org/private/y3biyvosuejkrtxbpdv1a -- but that still gives the ugly warning about not recognising the geometry column when the table is reflected. Ideally, what I'd like to do is to get SQLAlchemy's own table reflection to recognise the geometry columns. How would I plumb them together?

  • Querying tables based on other column values

    - by blcArmadillo
    Is there a way to query different databases based on the value of a column in the query? Say for example you have the following columns: id part_id attr_id attr_value_ext attr_value_int You then run a query and if the attr_id is '1' is returns the attr_value_int column but if attr_id is greater than '1' it joins data from another table based on the attr_value_ext.

  • How can I generate a flat excel file from a .rdl report?

    - by NotDan
    I have a .rdl report that formats data as a report. I want to export that data to excel as a flat table with the raw data that was returned based on the params in the report.

  • extbase mapping to an existing table doesn't work

    - by hering
    I've extended the pages table and now I want to use some of the data in a domain object called "Tags". So I tried the following in the /Configuration/TypoScript/setup.txt: plugin.myextension.persistence.classes.Tx_myextension_Domain_Model_Tag { mapping { tableName = pages recordType = Tx_myextension_Domain_Model_Tag columns { tx_myextension_tag_name.mapOnProperty = name uid.mapOnProperty = id } } } But It seems that the extension tries to access the table Tx_myextension_Domain_Model_Tag (which doesn't exist) This is the error I receive: Tx_Extbase_Persistence_Storage_Exception_SqlError` Table 'tx_myextension_domain_model_tag' doesn't exist: SELECT tx_myextension_domain_model_tag.* FROM tx_myextension_domain_model_tag WHERE tx_myextension_domain_model_tag.id = '24' LIMIT 1 What have I done wrong?

    - by Chuck Folds
    I'm in need of some basic TSQL help. Here's my table layout: Orders Table SSN ZipCode ZipLookup Table ZipCode State All columns are varchars. How would I get a list of States with the number of distinct SSN's in each state? Preferably, if a particular SSN has orders from multiple states only the state with the most orders would be counted for that SSN. Thank you for any tips you can give me.

  • Dynamically create categories for SQLite pivot/crosstab

    - by alj
    I realise it is possible to create a crosstab within sqlite, but is it possible to dynamically determine the relevant categories/columns at runtime rather than hardcoding them? Given the following example, it can get rather tedious ... SELECT shop_id, sum(CASE WHEN product = 'Fiesta' THEN units END) as Fiesta, sum(CASE WHEN product = 'Focus' THEN units END) as Focus, sum(CASE WHEN product = 'Puma' THEN units END) as Puma, sum(units) AS total FROM sales GROUP BY shop_id I managed to do this in SQLServer in a stored proceedure before and wondered if there was anything equivalent.

  • Dynamic Typed Table/Model in J2EE?

    - by Viele
    Hi, Usually with J2EE when we create Model, we define the fields and types of fields through XML or annotation before compilation time. Is there a way to change those in runtime? or better, is it possible to create a new Model based on the user's input during the runtime? such that the number of columns and types of fields are dynamic (determined at runtime)? Help is much appreciated. Thank you.
