MVC Html.DropDownList closes prematurely in IE7

- by Jon

I'm using ASP.NET MVC with jquery. I have a couple of dropdownlists. When I select one via mouse click and then scroll down over the items using the mouse/cursor, the list closes before a selection can be made, before the mouse can be clicked. This doesn't happen when I open them and then up/down arrow to select an item. It doesn't happen all of the time, but a lot. Just to try something different, I added a jquery "select" control with hardcoded values (options) and it displays the same behavior. Any ideas? <%: Html.DropDownList("Accounts", (IEnumerable)ViewData["Accounts"], "-- Select an account --")% Thank you

For example (again in pseudo-code): $_GET['percentage'] = 10; SELECT 10% of data from table order by rand() If this IS possible, how could I do it?

- by andrew

Hi, i have a select box like that <select name="sehirler_post" id="sehirler_post"> i am getting values via jquery. i know two different ways to get values. first one is : var sehirler_post = jQuery('select#sehirler_post').attr('value'); second one is: jQuery('#sehirler_post ').val() and finally here is my problem, i have something like this: jQuery("#okay").load("ajax_post_category.php?okay="+id+""); i would like to use selectbox value instead of id (okay="+id+"). so, i must change +id+ part with select box value. however i can not do it.. i tried to do like that: jQuery("#okay").load("ajax_post_category.php?okay="+jQuery('#sehirler_post').val()+""); it did not work. there must be a way, so i can use selectbox value instead of id in my load function. if anyone helps me, ill be so glad. regards

Selecting data effectively sql

- by learner135

Hi, I have a very large table with over 1000 records and 200 columns. When I try to retreive records matching some criteria in the WHERE clause using SELECT statement it takes a lot of time. But most of the time I just want to select a single record that matches the criteria in the WHERE clause rather than all the records. I guess there should be a way to select just a single record and exit which would minimize the retrieval time. I tried ROWNUM=1 in the WHERE clause but it didn't really work cause I guess the engine still checks all the records even after finding the first record matching the WHERE criteria. Is there a way to optimize in case if I want to select just a few records? Thanks in advance. Edit: I am using oracle 10g.

Types in Union or Concat cannot be constructed with hierarchy

- by user927777

I am trying to run a query very similar to the following: (from bs in DataContext.TblBookShelf join b in DataContext.Book on bs.BookID equals b.BookID where bs.BookShelfID == bookShelfID select new BookItem { Categories = String.Join("<br/>", b.BookCategories.Select(x => x.Name).DefaultIfEmpty().ToArray()), Name = b.Name, ISBN = b.ISBN, BookType = "Shelf" }).Union(from bs in DataContext.TblBookShelf join bi in DataContext.TblBookInventory on bs.BookID equals bi.BookID select new BookItem { Categories = String.Join("<br/>", bi.BookCategories.Select(x => x.Name).DefaultIfEmpty().ToArray()), Name = bi.Name, ISBN = bi.ISBN, BookType = "Inventory" }); I am receiving "Types in Union or Concat cannot be constructed with hierarchy" after the statement executes, I need to to be able to get a list of categories to display with each book. If anyone could shed some light on a possible solution, it would be greatly appreciated.

SQL Math in Excel VBA

Excel seems to have a problem with doing math in SQL queries. SELECT ( SELECT sum(column) FROM table1 ) + ( SELECT sum(column) FROM table2 ) AS total This technique works completely fine in ASP and ASP.NET. Has anyone had success doing this in Excel VBA? (My database engine is SQL Server 2000.)

What is the best way of inserting a datetime value using dynamic sql

- by jaffa

What is the best way of inserting a datetime value using a dynamic sql string, whilst at the same time being able to handle the possibility of the value being null? The current statement inserts into a table from a select statement built using a string. The datetime value is stored in a parameter and the parameter is used in the select. Like so: set @execsql = 'Insert into ( start_date ) SELECT ( ''' + CAST(start_date as VARCHAR) + ''' + ')'

Why is my php script freezing?

- by William

What is causing my php code to freeze? I know it's cause of the while loop, but I have $max_threads--; at the end so it shouldn't do that. <html> <head> <?php $db = mysql_connect("host","name","pass") or die("Can't connect to host"); mysql_select_db("dbname",$db) or die("Can't connect to DB"); $sql_result = mysql_query("SELECT MAX(Thread) FROM test_posts", $db); $rs = mysql_fetch_row($sql_result); $max_threads = $rs[0]; $board = $_GET['board']; ?> </head> <body> <?php While($max_threads >= 0) { $sql_result = mysql_query("SELECT MIN(ID) FROM test_posts WHERE Thread=".$max_threads."", $db); $rs = mysql_fetch_row($sql_result); $sql_result = mysql_query("SELECT post FROM test_posts WHERE ID=".$rs[0]."", $db); $post = mysql_fetch_row($sql_result); $sql_result = mysql_query("SELECT name FROM test_posts WHERE ID=".$rs[0]."", $db); $name = mysql_fetch_row($sql_result); $sql_result = mysql_query("SELECT trip FROM test_posts WHERE ID=".$rs[0]."", $db); $trip = mysql_fetch_row($sql_result); if(!empty($post)) echo'<div class="postbox"><h4>'.$name[0].'['.$trip[0].']</h4><hr />' . $post[0] .

Subquery vs Traditional join with WHERE clause?

- by BradC

When joining to a subset of a table, any reason to prefer one of these formats over the other? Subquery version: SELECT ... FROM Customers AS c INNER JOIN (SELECT * FROM Classification WHERE CustomerType = 'Standard') AS cf ON c.TypeCode = cf.Code INNER JOIN SalesReps s ON cf.SalesRepID = s.SalesRepID vs the WHERE clause at the end: SELECT ... FROM Customers AS c INNER JOIN Classification AS cf ON c.TypeCode = cf.Code INNER JOIN SalesReps AS s ON cf.SalesRepID = s.SalesRepID WHERE cf.CustomerType = 'Standard' The WHERE clause at the end feels more "traditional", but the first is arguably more clear, especially as the joins get increasingly complex. Only other reason I can think of to prefer the second is that the "SELECT *" on the first might be returning columns that aren't used later (In this case, I'd probably only need to return cf.Code and Cf.SalesRepID)

Doing a UNION ALL on two different COUNTs using Linq-To-Sql

- by Danno

Is it possible to write a linq-to-sql statement that will return two different COUNTs that have been put into a single dataset using UNION ALL? I know this is syntactically wrong but here's what I'm trying to do: (from t1 in TableOne select t1).Count().Union( (from t2 in TableTwo select t2).Count() ) Here's the sql I would like would like to have generated: select count(*) from TableOne union all select count(*) from TableTwo I realize that Count() returns an int and does not have a Union method on it and therein lies my question. Can Linq-to-Sql be written that will achieve what I'm after?

which sql consumes less memory

- by prmatta

Yesterday I asked a question on how to re-write sql to do selects and inserts in batches. I needed to do this to try and consume less virtual memory, since I need to move millions of rows here. The object is to move rows from Table B into Table A. Here are the ways I can think of doing this: SQL #1) INSERT INTO A (x, y, z) SELECT x, y, z FROM B b WHERE ... SQL #2) FOREACH SELECT x,y,z FROM B b WHERE ... INSERT INTO A(x,y,z); END FOREACH; SQL #3) FOREACH SELECT FIRST 2000 x,y,z FROM B b WHERE ... INSERT INTO A(x,y,z); END FOREACH; SQL #4) FOREACH SELECT FIRST 2000 x,y,z FROM B b WHERE ... AND NOT EXISTS IN (SELECT * FROM A) INSERT INTO A(x,y,z); END FOREACH; Are any of the above incorrect? The database is informix 11.5.

MSSQL / T-SQL : How to update equal percentages of a resultset?

- by Kent Comeaux

I need a way to take a resultset of KeyIDs and divide it up as equally as possible and update records differently for each division based on the KeyIDs. In other words, there is SELECT KeyID FROM TableA WHERE (some criteria exists) I want to update TableA 3 different ways by 3 equal portions of KeyIDs. UPDATE TableA SET FieldA = Value1 WHERE KeyID IN (the first 1/3 of the SELECT resultset above) UPDATE TableA SET FieldA = Value2 WHERE KeyID IN (the second 1/3 of the SELECT resultset above) UPDATE TableA SET FieldA = Value3 WHERE KeyID IN (the third 1/3 of the SELECT resultset above) or something to that effect. Thanks for any and all of your responses.

Rails activerecord includes. How to access the included columns?

- by Lee Quarella

I my User has_many :event_patrons and EventPatron belongs_to :user. I would like to slap together the user with one specific event patron with something like this sql statement: SELECT * FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 So in rails I tried this: User.all(:joins => :event_patrons, :condidions => {:event_patrons => {:event_id => 1}}) But that gives me SELECT users.* instead of SELECT *: SELECT `users`* FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 I then tried to switch the :joins with :include and got a whole jumbled mess that still returned me only the columns in User and none from EventPatron. What am I missing?

calculating change (over a period) for a dated field

- by morpheous

I have two tables with the following schema: CREATE TABLE sales_data ( sales_time date NOT NULL, product_id integer NOT NULL, sales_amt double NOT NULL ); CREATE TABLE date_dimension ( id integer NOT NULL, datestamp date NOT NULL, day_part integer NOT NULL, week_part integer NOT NULL, month_part integer NOT NULL, qtr_part integer NOT NULL, year_part integer NOT NULL, ); I want to write two types of queries that will allow me to calculate: period on period change (e.g. week on week change) change in period on period change (e.g. change in week on week change) I would prefer to write this in ANSI SQL, since I dont want to be tied to any particular db. [Edit] In light of some of the comments, if I have to be tied to a single database (in terms of SQL dialect), it will have to be PostgreSQL The queries I want to write are of the form (pseudo SQL of course): Query Type 1 (Period on Period Change) ======================================= a). select product_id, ((sd2.sales_amt - sd1.sales_amt)/sd1.sales_amt) as week_on_week_change from sales_data sd1, sales_data sd2, date_dimension dd where {SOME CRITERIA) b). select product_id, ((sd2.sales_amt - sd1.sales_amt)/sd1.sales_amt) as month_on_month_change from sales_data sd1, sales_data sd2, date_dimension dd where {SOME CRITERIA) Query Type 2 (Change in Period on Period Change) ================================================= a). select product_id, ((a2.week_on_week_change - a1.week_on_week_change)/a1.week_on_week_change) as change_on_week_on_week_change from (select product_id, ((sd2.sales_amt - sd1.sales_amt)/sd1.sales_amt) as week_on_week_change from sales_data sd1, sales_data sd2, date_dimension dd where {SOME CRITERIA) as a1), (select product_id, ((sd2.sales_amt - sd1.sales_amt)/sd1.sales_amt) as week_on_week_change from sales_data sd1, sales_data sd2, date_dimension dd where {SOME CRITERIA) as a2) WHERE {SOME OTHER CRITERIA}

Execute query stored in variable in a very specific way

- by niao

Greetings, I have a problem as follows: I have an SQL variable declared: DECLARE @myVariable nvarchar(max) a third party library set a value for this variable. To simplify, lets say that the value is as follows: SET @myVariable = 'Select ROWGUID from MySampleTable' Now, I want to execute the following query: SELECT ROWGUID FROM myTable WHERE ROWGUID in (exec sp_executesql @myVariable ) However, the above statement does not work because it returns an error telling me that I can't execute stored procedure in that way. I made a workaround and this is what I wrote: create table #temptable (ID uniqueidentifier null) if(@myVariable is not null AND @myVariable !='') insert into #temptable exec sp_executesql @myVariable SELECT ROWGUID FROM myTable WHERE ROWGUID in (select * from #temptable) DROP TABLE #temptable This works fine.However I don't think it is a good idea to use temporary table. How can I achieve the same result without necessity of creating temporary tables? I am using SQL SERVER 2005
