  • AngularJS directives with async content

    - by SirDavik
    I'm generating a dynamic number of Google Charts tables after receiving the content through an ajax request and I wanted to apply an accordion effect on them. I wanted to know if I could do that with directives (since if I just code render the angular tags they won't get interpreted). I don't need a code example, just a short answer to see if I should learn directives or if I should do it in a different way (I was thinking routeParams). Thanks!

  • SQL - when should you use "with (nolock)"

    - by Andy White
    Can someone explain the implications of using "with (nolock)" on queries, when you should/shouldn't use it? For example, if you have a banking application with high transaction rates and a lot of data in certain tables, in what types of queries would nolock be okay? Are there cases when you should always use it/never use it?

  • Dynamic Data - Make Friendly Column Names?

    - by davemackey
    I've created a Dynamic Data project with an Entity Framework model. It works nicely. But, right now it shows all my database tables with the db column names - which aren't always the most friendly (e.g. address_line_1). How can I got about giving these more friendly column titles that will display to the end user?

  • How do I generate Entity Framework 4.0 classes from the command line that have different names than

    - by Josh Kodroff
    I want to generate Entity Framework 4.0 classes from a (legacy) database from a command line, but I have 2 transformations I want: Tables/columns are lowerCamelCase and I want my classes/members to be UpperCamelCase. I want to suffix my classes with "Dto". Any idea how this might be accomplished? I'm a total newbie to EF, but I have a decent understanding of Linq to Sql and was able to accomplish the same task by doing: sqlmetal - dbml - xml mapping file and .cs file.

  • Convert Object Hierachey to Object Array

    - by Killercam
    All, I want to create an object array foo[], where the constructor for Foo is public Foo(string name, string discription){} I have a database object which has a structure (not incuding stored procedures, functions or views for simplicity) like public class Database { public string name { get; set; } public string filename { get; set; } public List<Table> tables { get; set; } public Database(string name, string filename) { this.name = name; this.filename = filename; } } protected internal class Table { public string name { get; set; } public List<Column> columns { get; set;} public Table(string name, List<Column> columns) { this.name = name; this.columns = columns; } } protected internal class Column { public string name { get; set; } public string type { get; set; } public Column(string name, string type, int maxLength, bool isNullable) { this.name = name; this.type = type; } } I would like to know the quickest way to add Column and Table information to the Foo[] object array? Clearly I can do List<Foo> fooList = new List<Foo>(); foreach (Table t in database.tables) { fooList.Add(new Foo(t.Name, "Some Description")); foreach (Column c in t.columns) fooList.Add(new Foo(c.Name, "Some Description")); } Foo[] fooArr = fooList.ToArray<Foo>(); But is there a quicker way? Clearly LINQ is likely to be slower for a query that does a simalar operation, but I care allot about speed here so any advice would be appreciated. Perhaps the use of a HashSet would be the way to go as there will not be duplicate entries... Thanks for your time.

    Is this equivalent to a LEFT JOIN? SELECT DISTINCT a.name, b.name FROM tableA a, (SELECT DISTINCT name FROM tableB) as b It seems as though there is no link between the two tables. Is there an easier / more efficient way to write this?

  • MySQL - Limit a left join to the first date-time that occurs?

    - by John M
    Simplified table structure (the tables can't be merged at this time): TableA: dts_received (datetime) dts_completed (datetime) task_a (varchar) TableB: dts_started (datetime) task_b (varchar) What I would like to do is determine how long a task took to complete. The join parameter would be something like ON task_a = task_b AND dts_completed < dts_started The issue is that there may be multiple date-times that occur after the dts_completed. How do I create a join that only returns the first tableB-datetime that occurs after the tableA-datetime?
