MySQL - Select Points Column From User Table (Entered Username)
Jun 27, 2012I have this MySQL Query glitch in my VB.NET program. Here is the query in VB.NET:
"SELECT Points FROM user WHERE Username = '" & UsernameText.Text & "';"
It will select the points column from the user table from the Username they entered. When I deploy this it will set the value for points to 0 on their account. I'm not even inserting anything in.

DB/Reporting :: Column 'TYPE' Is Constrained To Be Unique?
Feb 20, 2009I'm using vb2005. I'm writing a little application which allows a person to type in a new value in a combobox (which I've bound to a field in a table) which can be updated to the database. I then refresh the dataAdapter by clearing it and re-filling it again when the user saves a new item. That part works fine. My problem occurs when the user selects a stationary item from the combobox. The first select works fine until they try to select another item. Then I get the following error: ConstraintException was unhandled: Column 'TYPE' is constrained to be unique. Value 'False' is already present.

Feb 3, 2010I am using SQLite and what I am doing is passing a simple SQL statement to the database, however I want to also return the Unique ID that the insert statement has been entered to, however I am not sure how to do this within a single SQL statement.
My code is below:
Dim mySQL As String = "INSERT INTO DisplaySetFolderTbl (parentID, folderName) VALUES ('" & selNode.Tag & "','" & Trim(Me.txtName.Text) & "')"
Dim cmd As New SQLiteCommand(mySQL, MISData.Instance.dbDRV)

cmd.ExecuteNonQuery()
Catch
Exit Sub

MISData.Instance.dbDRV is the connection string

Connect To A Table To Get The Next Unique Id?
Jun 6, 2012In my app, I connect to a table to get the next unique id (t_IDs). The code basicly looks up a specific table name and returns the next value. This is fine in testing, but the application is going to be used between multipul sites. I can see an issue where this may cause the app to slow down while it waits the next id before saving all the data to another table.
My question is, Is there away to set a SQL trigger to go and get the next id value and update the record when a new record is created? BTW - I did look at the uniqueidentifier option (NewId()) but the Id is too long. I need 1,2,3,4 etc.
Know If The Table Column Is Unique?
Mar 15, 2012currently, what i want to do is, add a column in a table "default" during runtime. Well, I've got that covered already.
The problem is, the column names are actually taken from the users input through a textbox or drop down list and of course, if the same column is added already in the table, it generates an error since it has to be unique.
That is why i wonder if it is possible to know if a column already exists without viewing the form which contains the grid view of that table?

VS 2008 Generating Unique IDs In A Table?
Dec 6, 2009creating unique IDs for each row in a table, to avoid duplicates when inserting the data to a server. The table looks like this:
+--------------+----------+------+-------------+
| brikkenummer | tid | post | anvendt_tid |
+--------------+----------+------+-------------+
| 3086360 | 09:43:02 | 98 | 09:43:02 |
[code]....
"Brikkenummer" is the number of a device that each person carries with him/her, and "tid" is the time the runner has passed a specific post. The post he/her has passed is described in the column "post".Out of these three columns, is it possible to generate some kind of unique ID? The ID that is generated have to be the same if a row is displayed twice or more, to avoid duplicate entries.

DB/Reporting :: Table Columns Into Table Adaptor?
Jul 7, 2011Rather than running numerous queries in Access I am trying to write a front end for a DB2 database. The Access database is getting to a size that it is causing Access 2007 to have reliability issues and frequent compacting is required. I have created the Dataset, the Table Adaptors, and the Connection String already, but when I put in a bit of code in to fill the Table Adaptors the remote connection I have to work is going crazy (chewed up about 180MB before I realised it was pulling data from work).
Before I started the project I copied the .accdb to my local PC HDD and I pointed the connection string to it, but it still looks like it is trying to pull data from the work network. If it was a small database I wouldnt be concerned but it is pulling major data every time I run it. I have only 2 out of the 4 Table Adaptors running and it didnt fill them even after 10 minutes.
Here is the code I was trying to run... Server name has been substituted for Server for obvious work reasons.
Because the tables are so large I was looking for a way to pull only the columns I need to from the tables, I tried adding .SOFT_ID to the first line of code but the TA spat the dummy message below...
Value of type 'System.Data.DataColumn' cannot be converted to Application_Name.DS_DB2Database.Server_SOFTDataTable'.
Code:
Me.TA_ServerSOFT.Fill(Me.DS_DB2Database.ServerSOFT.SOFT_ID)
Me.TA_ServerSOFT_FOUND.Fill(Me.DS_DB2Database.ServerSOFT_FOUND)
Me.TA_ServerHARD.Fill(Me.DS_DB2Database.ServerHARD)
Me.TA_ServerREF_SUP.Fill(Me.DS_DB2Database.ServerREF_SUP)
I would also like to pull just the data columns I need to speed up the query.
Note: In case youre wondering why I am not connecting directly to the DB2 database. I currently dont know where it is stored and while leveraging Access I am trying to put a level of separation between the app and the db for the time being, later I will try connect directly.
