Hello,

I'm using next code for reading data from database:

Using myIDataReader As IDataReader = CType(DataProvider.Instance().ExecuteSQL("SELECT ItemsID FROM {databaseOwner}{objectQualifier}SomeItems WHERE ItemsCode = @ItemsCode AND FirmID = @FirmID", ItemsCodeParam, FirmIDParam), IDataReader)
            myIDataReader.Read()

            intItemsID = myIDataReader.GetInt32(0)
        End Using

 

and it all worked fine until this error:

Error   Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

 

I thought I closed sql connection with "using". Am I wrong? I chaged max pool size and it work little longer, until crash. After that I set "pooling=false", but that is not right solution.  I forgot to mention I'm using AJAX, if that is relevant for this problem...

 

Thanks

I'm not sure why Using would close the read, but myIDataReader.Close() should work for you.

Hi,

 

thanks for reply...

 

Does myIDataReader.Close()  also close sql connection?

Yes I believe it does.

The problem with using the ExecuteSQL statement that you used is that that statement doesn't really know it's returning a datareader, so it won't close it automatically.

What about ExecuteReader or ExecuteScalar?
