Databases :: MySql Transaction Inside A Loop - Delete A Bunch Of Records

Sep 30, 2010

I'm trying to delete a bunch of records in mysql. The record info to delete (userid, name) is stored in an arraylist. It seems to only delete the first record and gives an error ("Transaction has already been rolled back or is not pending.") afterwards. I have the transaction commit inside the loop which I think is the issue but not sure how to go further if I bring it outside of the loop. Here's the relevant bits of the code.

try
{
ArrayList alist = new ArrayList();
//alist gets populated with data like (12345,robot)(23456,car) here.
MySqlConnection conn2 = new MySqlConnection(query_connection);
conn2.Open();
MySqlCommand command2 = conn2.CreateCommand();
MySqlTransaction mytransaction;
mytransaction = conn2.BeginTransaction();
command2.Transaction = mytransaction;
for (int i = 0; i < alist.Count; i++)
{
string[] s = alist[i].ToString().Split(',');
try
{
command2.CommandText = "DELETE from users_settings WHERE UserID=" + s[0].ToString();
command2.ExecuteNonQuery();
command2.CommandText = "DELETE from users WHERE ID=" + s[0].ToString();
command2.ExecuteNonQuery();
mytransaction.Commit();
}
catch (Exception e){
mytransaction.Rollback();
}
}
}
catch(Exception e){
}

Databases :: MySQL And Auto Generating Insert,Update - Delete Statements?

May 11, 2010

Before I get too far down the road I just want some advice. I'm building a web app using VWD2008 and MySQL 5. I've got the membership provider stuff working fine and have an odbc connection setup which works "fine". what I've noticed is that when I configure a new sqldatasource (that will be used to provide data to a listview or something) the Advanced -> generate Insert,Update..... option is disabled. I'm assuming its because of the sql syntax difference of the square brackets issue between MS SQL Server and MySQL.

Before I start writing all my own insert and update statements does anyone know if there is a way to get MySQL and VWD to talk the same language, maybe a different connector or something. I'm using mysql-connector-odbc-3.51.15

Databases :: MySQL Connector With 64 Bit?

May 3, 2010

I just moved to a new 2008 64 Bit Server. We are using MySQL, now also the 64 Bit version. Now I found out that there is a 64 Bit ODCB Driver, but not an 64 Bit Net/Connector.

Is that an issue or is the .NET Connector by default 32 and 64 Bit?

Databases :: Use MySQL Views Or Implement XML

Feb 3, 2011

I´m involved in a project that requires MySQL interaction, and I´m designing (or programming) the front end interface. SCENARIO: I´ve a MySQL database. (Now... Imagine a Webpage.aspx). I have a table inside the page with 2 rows: The first row has 3 columns... yes, cells!!, and the another one has no columns. In the first cell (1 row, 1 column) I have a treeview with a panoramic of my database (Treeview-Datasource: XML file that I build by myself with the hierarchy of my database). Then, in the 2nd cell (1 row, 2 column) I have a Radiobuttonlist; the aim of this cell is show only the name of every data placed in the selected entity (located in the treeview). And in the third cell (1 row, 3 column) I have 3 buttons: the first one is "NEW" (Should create a new item in the entity of the database - selected in the treeview) the second one is "EDIT" (Should edit the item of my database_entity selected in the radiobuttonlist)
And the third one is "SAVE"... (No words!!)

In the fourth cell (2 row, unique column)I have a FormView. To fill data, to arrange it in two columns, and to show textboxes allowing me introduce information to perform the button actions. I´m new in this, but I´ve seen that probably, I can make it using views (programming them in the database) or using XML files (declarating and querying my database as well as I want) but, in any case, the two ways requires build a view or xml file for every entity of my database that I want modify. I´m Sure that all of us know a short method or something.

Databases :: Why Are The Table Columns Different From MySQL Then With MS SQL

Sep 9, 2010

I try to work with MYSql (because it's free) and I saw that the colums are different then when they are exployed in MS SQL?

Why is this? The most strange differents is that in MySQL there is no applicationId in the membership table.

This differents in tables cost me more time to do a export and import from MS SQL to MySQL.
