• How to tune ASP.NET CreateUserWizard?

  - by Max

  I have created ASP.NET WebForms site on IIS 7.5. I want to create step by step user registration. I want to store the basic and detailed information about registered users in a specially created database table (not in aspnet_users table). I want to validate email first and then prevent next registration step for the user whose email address already exists in the database. At the last registration step I want to present summary form. All previous input and select fields should be duplicated in this form with "disabled" attribute. Please tell me how to adjust CreateUserWizard ASP.NET Control and web.config file to these needs?

• Please for efficient query

  - by user278618

  I want to have efficient query to get some rows from my table. Here is I think the best presentation of my table. -Somedate is not duplicated - it is date of modifiedon -a,b,c are parent ids, let say countryCode -1,2,3,4 are subparent, let say citycode -guids are id of rows -true, false are values of rows - one can name this column - freshAir a 1 GUID somedate true a 1 GUID somedate true a 2 GUID somedate false a 2 GUID somedate false b 3 GUID somedate false b 3 GUID somedate false b 3 GUID somedate false b 4 GUID somedate false c 5 GUID somedate true c 6 GUID somedate true c 6 GUID somedate false c 6 GUID somedate false c 7 GUID somedate false I want the most recent rows MAX(modifiedon) grouped by countrycode and citycode and in this groups I need elements which have another values (true, false). And in result I want: a 1 GUID somedate true a 2 GUID somedate false c 5 GUID somedate true c 6 GUID somedate false c 7 GUID somedate false Look that in result I don't want to have records with "b", because all rows have the same value (false).

  My product table is id type price location 1 chips $3 aisle3 I have a question with adding the products in groups. There is a quantity field(nonmodel) where the user can enter the quantity While adding a new product if the user enters: type: soda quantity: 3 Then there 3 records should be created in product model with type= soda like the following. id type 2 soda 3 soda 4 soda If user enters location: aisle4 quantity: 2 Then id location 5 ailse4 6 ailse4 Can you tell me how to pass the nonmodel field 'quantity' to the rails(model or controller) and how use it to add the products in groups as mentioned above? or should I create a column called quantity in my product table?

• SQL Server Mutliple Joins Taxing CPU

  - by durilai

  I have a stored procedure on SQL server 2005. It is pulling from a Table function, and has two joins. When the query is run using a load test it kills the CPU 100% across all 16 cores! I have determined that removing one of the joins makes the query run fine, but both taxes the CPU. Select SKey From dbo.tfnGetLatest(@ID) a left join [STAGING].dbo.RefSrvc b on a.LID = b.ESIID left join [STAGING].dbo.RefSrvc c on a.EID = c.ESIID Any help is appreciated, note the join is happening on the same table in a different database on the same server.

• Samba issue with sharing directories on NTFS/FAT32

  - by Microkernel

  I have some strange problems with Samba server. I am using samba Version 3.5.4 on Ubuntu 10.10. I have two Windows XP machines, one on VirtualBox on Ubuntu and another office laptop. Windows machine on VirtualBox has no issues in accessing the shared folders, but the laptop is not able to access all the shared content. The issue faced on laptop is the following. Shared folders on ext3 drives have no issues in accessing, but the contents shared on NTFS and FAT32 drives (mounted ones) are not accessible. When I try to open the shared folder, it asks for user name and password, but doesn't accept when I provide it. (Even if I provide admin login details). I changed workgroup value to the domain_name in office laptop, but still the problem persists. Here is the smdb.conf I am using: [global] workgroup = XXX.XXX.ORG server string = %h server (Samba, Ubuntu) map to guest = Bad User obey pam restrictions = Yes pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . unix password sync = Yes syslog = 0 log file = /var/log/samba/log.%m max log size = 1000 dns proxy = No usershare allow guests = Yes panic action = /usr/share/samba/panic-action %d guest ok = Yes [homes] comment = Home Directories [printers] comment = All Printers path = /var/spool/samba read only = No create mask = 0700 printable = Yes browseable = No [print$] comment = Samba server's CD-ROM path = /cdrom force user = nobody force group = nobody locking = No Workgroup was defined as "HOMENET" before, changed it to domain name on the office laptop thinking it was the problem, but for no avail.

• Multiple Tables or Multiple Schema

  - by Yan Cheng CHEOK

  http://stackoverflow.com/questions/1152405/postgresql-is-better-using-multiple-databases-with-1-schema-each-or-1-database I am new in schema concept for PostgreSQL. For the above mentioned scenario, I was wondering Why don't we use a single database (with default schema named public) Why don't we have a single table, to store multiple users row? Other tables which hold users related information, with foreign key point to the user table. Can anyone provide me a real case scenario, which single database, multiple schema will be extremely useful, and can't solve by conventional single database, single schema.

• How to define one-to-many connection between a same model through another model

  - by Mekajiki

  I want to define one-to-many relationship as follows; User has one introducer User has many newcomers(who is introduced by the user) Use "Introduction" model instead of adding a column to users table. My table and model definition is as follows; DB Scheme: create_table "introductions", force: true do |t| t.integer "introducer_id" t.integer "newcomer_id" t.datetime "created_at" t.datetime "updated_at" User model: class User < ActiveRecord::Base has_many :introductions, foreign_key: :introducer_id has_many :newcomers, through: :introductions, source: :newcomer belongs_to :introduction, foreign_key: :newcomer_id belongs_to :introducer end Introduction model: class Introduction < ActiveRecord::Base belongs_to :introducer, class_name: 'User' belongs_to :newcomer, class_name: 'User' end This works fine: user1.newcomers.push user2 but, user2.introducer # => nil How can I define belongs_to relationship correctly?

• How to implement multi relationship in MS SQL?

  - by Ethan

  I’m trying to design a database to use with ASP.net MVC application. Here is the scenario: There are three entities and users can post their comments for each of these different entities. I just wonder how just put one table for Comments and link all other entities to it. Obviously, Comments table needs 3 references (foreign key) to those tables but as you know these foreign keys can’t be null and just one of them can be filled for each row. Is there any better way than implementing three different tables for each entity’s comments? Cheers Ethan

• Relationship Modelling in Core Data

  - by Stevie

  Hi there, I'm fairly new to Objective C and Core Data and have a problem designing a case where players team up one-on-one and have multiple matches that end up with a specific result. With MySQL, I would have a Player table (player primary key, name) and a match table (player A foreign key, player B foreign key, result). Now how do I do this with Core Data? I can easily tie a player entity to a match entity using a relationship. But how do I model the inverse direction for the second player ref. in the match entity? Player Name: Attribute Match: Relationship Match Match Result: Attribute PlayerA: Relationship to Player (<- Inverse to Player.Match) PlayerB: Relationship to Player (<- Inverse to ????) Would be great if someone could give me an idea on this! Thanks, Stevie.

• checkUnique function?

• T-SQL Re-Assigning Order Numbering

  - by Meltdown

  Say I have a table with a field called "ordernum" that denotes the order of a given set of rows. Now imagine that I delete one of these rows. What type of query would work best for re-assigning the order numbers so that they remain sequential? Here's an example: id group_id name ordernum active --------------------------------------------------- 0_____0______'Name1'___5__true 1_____0______'Name2'___4__true 2_____0______'Name3'___3__true 3_____1______'Name4'___2__true 4_____1______'Name5'__1__true 5_____1______'Name6'__NULL___false Now if I deleted the column with id='4' how would I reset the values in the 'ordernum' field for that specific group? Is this even possible? Or if I added a new row. (The first time the rows are created they are sorted by date, but then the user has the option to set the order himself.) In my table design I have a column 'active' boolean. If 'active' is set to false, then 'ordernum' is set to NULL. Otherwise it should be given an order number.

• TinyMCE: Double forecolor and backcolor buttons?

• SQLite and PostgreSql longtext

  - by Nik

  Hello all, Does anyone know how to change a column in SQLite and PostgreSQL to LONGTEXT? I have done so in MySQL successfully with: "ALTER TABLE projects MODIFY description LONGTEXT;" But this clause doesn't seem to work on SQLite. I tried hard to find documentation on PostgreSQL, but that site's format really makes people puke. SQLite's website is better but the only command I find relevant, alter table, doesn't seem to support changing column data type at all. ( infact, it doesn't even allow changing column name!!!) Thanks all!

• sql server 2005 indexes and low cardinality

  - by Peanut

  How does SQL Server determine whether a table column has low cardinality? The reason I ask is because query optimizer would most probably not use an index on a gender column (values 'm' and 'f'). However how would it determine the cardinality of the gender column to come to that decision? On top of this, if in the unlikely event that I had a million entries in my table and only one entry in the gender column was 'm', would SQL server be able to determine this and use the index to retrieve that single row? Or would it just know there are only 2 distinct values in the column and not use the index? I appreciate the above discusses some poor db design, but I'm just trying to understand how query optimizer comes to its decisions. Many thanks.

• Microsoft Business Intelligence. Is what I am trying to do possible?

  - by Nai

  Hi guys, I have been charged with the task of analysing the log table of my company's website. This table contains a user's click path throughout the website for a given session. My company is looking to understand/spot trends based on the 'click paths' of our users. In doing so, identify groups of users that take on a certain 'click path' based on age/geography and so on. As you can tell from the title, I am completely new to BI and its capabilities so I was wondering: Are our objectives attainable? How should I go about doing this? I am currently reading books online as well as other e-books I have found. All signs seem to suggest this is possible via sequence clustering. Although the exact implementation and tweaks involved are currently lost on me. Therefore, if anyone has first hand experience in such an undertaking, I would be awesome if you could share it here. Cheers!

• SQL Server - Query Short-Circuiting?

  - by Sam Schutte

  Do T-SQL queries in SQL Server support short-circuiting? For instance, I have a situation where I have two database and I'm comparing data between the two tables to match and copy some info across. In one table, the "ID" field will always have leading zeros (such as "000000001234"), and in the other table, the ID field may or may not have leading zeros (might be "000000001234" or "1234"). So my query to match the two is something like: select * from table1 where table1.ID LIKE '%1234' To speed things up, I'm thinking of adding an OR before the like that just says: table1.ID = table2.ID to handle the case where both ID's have the padded zeros and are equal. Will doing so speed up the query by matching items on the "=" and not evaluating the LIKE for every single row (will it short circuit and skip the LIKE)?
