DB/Reporting :: SQL Connection Open/close?
Dec 16, 2011SQL connections confuse me sometimes In almost every SQL related code on the internet the routine is like this;
* Open connection
* Execute SQL command
* Close connection
Is it good practice to just open a connection when the application starts and use that connection until the application closes?I know that sequential connections are required when processing more queries, but what if I need to poll a certain Table every x seconds? Isn't is better to keep that single connection open for as long as the application is running (and re-open when a failure occurs) instead of opening a new connection every x seconds?

View 4 RepliesClose Oracle Connection In Program?
Aug 13, 2011In my program I got multiple spots where I open a Connection to an Oracle database, read some lines via a stored procedure which returns me a cursor, put them in an IDataReader, close the connection and go on.
Now everything works fine till the point of closing the connection. I've watched the connections opened to the database via TOAD for Oracle and I figured out, that the database seems to keep an connection opened after I said m_Connection.Close and m_Connection.Dispose.
I use Oracle.DataAccess and get an error after a short time, that there are to many connections. I debuged my session and made sure, that vb performs the close() command and it does it, but the database not.

View 3 RepliesDB/Reporting :: Changing An App From CE To SQL Server Express?
Oct 28, 2009I started coding my first "real" stand-alone desktop application in VB 2008 Express. I was led into believing that using SQL Express Compact Edition was the thing to use for my database since it would reside on each PC (laptops) that I installed the program on. I created all my tables and about 6 forms and all was going well until I came to the point where I need to display a grid showing data from multiple tables using what i think is supposed to be a view. Now the problem is that CE doesnt allow views. Here are my questions:
1. Can I convert my CE database file into an SQL Server Express file?
2. Do I have to re-write all my forms that are using the database? I am planning on creating my SQL Server Express database with the same table names and the same field names, data types, etc.

View 1 RepliesSql Server - Long Pause Trying To Close ADO.NET Connection Object
Oct 14, 2011I am performing a simple exercise of opening an SQL Server database connection, pulling the first record of a table from a DataReader object, and then closing the object. However, I have noticed that theres bit of a delay, about 5 seconds or so, in closing the connection. However, the delay only occurs after the command object executes the specified query. I've worked in a setup like this before and don't remember there being such a long delay while closing the connection. [Code] The connection closes almost immediately. What gives? I have narrowed it down to the where the .ExecuteReader line that causes the delay in the connection close. Whats causing the delay and how do I resolve it?

Quote: You have connected to a version of SQL Server later than SQL Server 2000. The version of Visual Studio or Access that you are using was released before the version of SQL Server to which you are connected. For this reason, you might encounter problems.
Please check with Microsoft to see if there is a service pack that you should apply to Visual Studio or Office in order to get support for the version of SQL Server to which you are connected.You can continue but any new object types might not be enumerated, and it will not be possible to save any objects or database diagrams that you create using the Visual Database Tools.I can not add tables or manage data fields. Does anyone know how to get the patch referred to in the message above? I can not find it via google or this forum.
