  • Caching result of SELECT statement for reuse in multiple queries

    - by Andrew
    I have a reasonably complex query to extract the Id field of the results I am interested in based on parameters entered by the user. After extracting the relevant Ids I am using the resulting set of Ids several times, in separate queries, to extract the actual output record sets I want (by joining to other tables, using aggregate functions, etc). I would like to avoid running the initial query separately for every set of results I want to return. I imagine my situation is a common pattern so I am interested in what the best approach is. The database is in MS SQL Server and I am using .NET 3.5.

  • How to select "child" entities in subview?

    - by Andy
    I am trying to manage a drill-down list of data. I've got an entity, Contact, that has a to-many relationship with another entity, Rule. In my root view controller, I use a fetched results controller to manage and display the list of Contacts. When a Contact is tapped, I push a new view controller onto the stack with a list of the Contact's Rules. I have not been able to figure out how to use a second fetched results controller to display the Rules, so I'm using the following: // create a set of the contact's rules rules = [NSMutableSet set]; rules = [self.contact mutableSetValueForKey:@"rule"]; // create an array of rules from the set arrayOfRules = [NSMutableArray arrayWithCapacity:[rules count]]; for (id oneObject in rules) [arrayOfRules addObject:oneObject]; // sort the array of rules NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"phoneLabel" ascending:YES]; [arrayOfRules sortUsingDescriptors:[NSArray arrayWithObject:descriptor]]; [descriptor release]; I create a set of Rules, then use that to create an array of Rules for sorting. I then use these two collections to populate the grouped table view. All of this appears to be working correctly. Here's my problem: There are several different actions a user can take in this view, and most of them require that I know which Rule was tapped. But I can't figure out how to get that. For instance, say a user wants to delete a Rule. It seems to me the proper approach is something like... [rules removeObject:ruleObjectToBeRemoved] ...but I can't figure out how to specifiy ruleObjectToBeRemoved. I hope all of this makes sense. As usual, thanks in advance for any advice you can offer.

  • SQL SELECT from third level table

    - by Spidermain50
    Ok I know little about SQL so bare with me... I'm trying to see if certain values exist in a third level table and I don't know how to go about it. Here is the scenario... I have a Accident table that holds accident information. It has 3 one-to-many child tables (Units, Occupants, NonMotorists). An each of those child tables have their own many-to-many child table (Alcohol). I need to be able to have some way of seeing if a range of values exists in a field in those Alcohol tables. Here is watered down version of what my structure for the tables looks like... --tblAccident--_ PK_AccidentNumber --tblAccidentUnit-- PK_PrimaryKey FK_AccidentNumber --tblAccidentOccupant-- PK_PrimaryKey FK_AccidentNumber --tblAccidentNonMotorist-- PK_PrimaryKey FK_AccidentNumber --tblAccidentUnitAlcohol-- PK_PrimaryKey FK_ForeignKey AlcoholValue <---- THIS IS WHAT I NEED TO SEARCH --tblAccidentOccupantAlcohol-- PK_PrimaryKey FK_ForeignKey AlcoholValue <---- THIS IS WHAT I NEED TO SEARCH --tblAccidentNonMotoristAlcohol-- PK_PrimaryKey FK_ForeignKey AlcoholValue <---- THIS IS WHAT I NEED TO SEARCH I hope this makes some sense as to what i am trying to accomplish. thank you

  • How to disable listbox auto select item when pressing key

    - by tomfox66
    I have a listbox where I want to copy and paste items within that listbox. Copy and paste works fine but everytime I press "Crtl + C" the item starting with the letter C is automatically selected. Can this automatic selection be disabled or am I missing something here Here is the copy and paste method I implemented: private void listBox_Script_KeyDown(object sender, KeyEventArgs e) { if (e.Control == true && e.KeyCode == Keys.C) { int test = listBox_Script.SelectedIndex; Clipboard.SetDataObject(listBox_Script.Items[listBox_Script.SelectedIndex], true); return; } if (e.Control == true && e.KeyCode == Keys.V) { if (Clipboard.GetDataObject().GetDataPresent(DataFormats.Text)) { listBox_Script.Items.Insert(listBox_Script.SelectedIndex + 1, Clipboard.GetDataObject().GetData(DataFormats.Text).ToString()); return; } }

  • php:: apply backticks to first word in sentence

    - by Hailwood
    Hi guys, basically what I am trying to do is, I have an array that looks something like this: array( array( 'select' =>'first string', 'escape' => true ), array( 'select' =>'second', 'escape' => true ), array( 'select' =>'the third string', 'escape' => true ), array( 'select' =>'fourth string', 'escape' => false ), ) I am looping over it and I want to end up with this output array( array( 'select' =>'`first` string', 'escape' => true ), array( 'select' =>'`second`', 'escape' => true ), array( 'select' =>'`the` third string', 'escape' => true ), array( 'select' =>'fourth string', 'escape' => false ), ) so basic rules are backticks are only applied if escape is true backticks are only applied to the first word in a sentence if there is only one word backticks are applied to the word My plan was to use if($item['escape']) { $pos = (strpos($item['select'], ' ') === false ? strlen($item['select']) : strpos($item['select'], ' ')); $item['select'] = '`' . substr($item['select'], 0, $pos) . '`' . substr($item['select'], $pos, strlen($item['select'])); } but the $item['select'] = line seems rather long winded, is there a better way to write it?

  • Java date long value changed after insert, select query

    - by StackExploded
    AFAIK, java Date type is independent from Timezone which means that it represents specific moment of time as long typed value. I found really weird thing here. This is the original value i tried to insert. (http-0.0.0.0-9080-4) 1352955600000 <-- long integer. (http-0.0.0.0-9080-4) Thu Nov 15 00:00:00 EST 2012 <-- User Friendly Format. After i finished inserting into Oracle 11g database, the value has changed! (http-0.0.0.0-9080-4) 1352952000000 (http-0.0.0.0-9080-4) Wed Nov 14 23:00:00 EST 2012 How could this happen?? The more weird thing is it only happens specific environments such as Jboss. I'm currently using below environments. java 1.6 ibatis 2.34 jboss-5.1 (server) tomcat 6.0 (local) oracle 11g Is there anybody who can give me a clue or link to be helpful? it really bugging me!!

  • Disabled Select drop down checking through PHP

    - by user541597
    I have a couple of drop down boxes I access through POST with PHP. When the boxes are disabled and not equal to zero I have the program do something. However when they are disabled I do not want them to do anything. The way I check if the boxes are active is by using an if statement if ($_POST['box'] != "blank"){ //do something } So basically I check if the box is not in the default blank position run the if statement. However when it is disabled I am not sure how to check or what kind of value it returns if any. What can I add to the if statement so it will not go into the loop when the boxes are disabled? I tried: if ($_POST['box'] != "blank" || $_POST['box'] != ""){ //do something } But that did not work. Any ideas?
