If i use MessageBox.Show to mysql error display the error number it is always 0, no matter which Exception it is. Shouldn't the Exception have a number like the number 1046? catch (MySqlException mysqlex) { MessageBox.Show(mysqlex.Number.ToString()); } EDIT: Sorry, i am using the MySQL-Connector / Net. c# mysql database exception visual-studio-2012 share|improve this question edited Mar 21 '14 at 11:31 asked Mar 21 '14 at 11:23 Proton 537 1 @GrantWinney Nope, that is a standard class contained in the Mysql.Data connector (see mysql stored procedure dev.mysql.com/doc/connector-net/en/…) –Erik Schierboom Mar 21 '14 at 11:25 Write mysqlex.Message in message box. What it says ? –Petar Repac Mar 21 '14 at 11:27 @ErikSchierboom Oh, okay, apparently I'm tired. I just expect properties to start with a capital letter normally, so I assumed this was some homespun thing. –Grant Winney Mar 21 '14 at 11:27 1 In fact Number property is with capital dev.mysql.com/doc/connector-net/en/…. Can you paste the real code ? This won't compile IMO. –Petar Repac Mar 21 '14 at 11:28 1 If error number is 0, the client is not able to connect to the server. Can you see if you have an inner exception? –Suresh Kumar Veluswamy Mar 21 '14 at 11:33 | show 2 more comments 2 Answers 2 active oldest votes up vote 1 down vote accepted You don't see a number because you did not connect to a database. And probably MySQL is assigning numbers to error exceptions. If you look at description for Number property here it says Gets a number that identifies the type of error. This number corresponds to the error numbers given in Server Error Codes and Messages. Because you did not made a connection to the server you cannot get server error code. Check your connection string. share|improve this answer answered Mar 21 '14 at 11:46 Petar Repac 2,9031623 a
found out a funny thing today. Or maybe not so funny when I think about it… The order page on one of my sites have not been working since early November, almost 6 months!! As I'm sure you understand it's not a very busy site, but usually I get a few orders per month so I should have noticed this a long time ago… The site is running on IIS/ASP.NET and MySQL server 5.0.45 using the MySQL .NET Connector and I'm using a SQL statement like this on the page: START TRANSACTION; INSERT INTO table1 (companyname,street,city,zip) VALUES (‘XS Tech','test','test','12345′); SELECT @id:=id FROM table1 where id = last_insert_id(); INSERT INTO table2 (id,contactname) VALUES (@id,'Max"); COMMIT; This statement was throwing an exception error: "MySql.Data.MySqlClient.MySqlException: Parameter ‘@id' must be defined" Since I could not really remember - ie had not properly documented - what changes I may have done to that page six months ago, it made trouble shooting a bit harder. But to make a long story short(er) - It turns out I had upgraded the MySQL .NET Connector and this was causing the error. The site was using MySql.Data.dll version 5.2.1.0. I tried to upgrade to 6.0.3.0 to no avail. But when downgrading to 5.1.4.0 it started to work just fine again. Finally, I found that this was indeed a change in the .Net Connector. (I'm not sure what version number but starting from 5.2.0 would be my guess) Starting from version 5.2.2 of the Connector you should add the Allow User Variables=True Connection String Setting in order to use User Defined Variables in your SQL statements. Example of Connection String: Database=testdb;Data Source=localhost;User Id=root;Password=hello;Allow User Variables=True 55 Comments (Click here to add your comment!) Craig Fowler Jul 22, 2009 @ 12:01:45 Thanks - just found this through Google and it saved me a hell of a lot of time (as I just upgraded .NET connector versions and my stuff broke for a similar reason). Steve Miller Sep 22, 2009 @ 23:05:23 Thank you. This is exactly what I needed. Saul Buendia Oct 27, 2009 @ 17:21:15 This was very helpful, I was having exactly the same problem. Thanks. Eliecer Jimenez Dec 03, 2009 @ 15:14:29 Many thanks, i was getting this error after upgrading the Mysql Connector… still i think this is foolish, Mysql user variable have always been defined by using an ‘@', they should have used some other method to identify user parameters… Adrian Dec 16, 2009 @ 09:23:27 thanks..but still the conector MUST BE FXED …!
