Sam

I had large database (transaction record > 1 million) at SQL Server and I
trying to load data from SQL Server into Datagrid via ASP.Net 1.1 and
ADO.Netx.

However, it give error message as below during processing.

While I checked at Query Analyser, it take 2 minutes + for search this
record and it is working fine.

Questions?
- What wrong at my coding? How about web.config?
- How to resolve this issue?
- Why ADO.Net / ASP.Net 1.1 does not support large connection pooling?

Please advise.

Many thanks.

ASPX Coding
--------------
Dim rptcon As New
SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim rptcmd As New SqlCommand()

rptcmd.CommandText = "Select GLDOC, GLDCT, gldate, GLEXA,
GLEXR, account_num, amount from f0911"
rptcmd.Connection = rptcon

Try
rptcon.Open()
Dim okrd As SqlDataReader = rptcmd.ExecuteReader()

ReportDataGrid.DataSource = okrd
ReportDataGrid.DataBind()

okrd.Close()

Finally
rptcon.Close()
End Try

End If

Web.Config Coding
---------------------
<!-- Web.Config Configuration File -->
<configuration>
<appSettings>
<add key="ConnectionString"
value="server=SQLSVR;database=ERP;uid=User;pwd=User;" />
</appSettings>
<system.web>
<compilation debug="true" />
<authentication mode="Forms">
<forms name="ERP" loginUrl="authentication.aspx"
protection="All" path="/" timeout="20"/>
</authentication>
<authorization>
<allow users="user1,user2"/>
<deny users="*"/>
</authorization>
<customErrors mode="Off" />
</system.web>
</configuration>
 
Hi Sam,

You can add "Connect Timeout=150" in the connection string as given below
and try.
"server=SQLSVR;database=ERP;uid=User;pwd=User;Connect Timeout=150"

This should solve the time out issue in fetching the data.
 
Even I changed the connection timeout at web.config. it is still same. Any
advise, please?

Hi,

You can try this:

rptcon.Open()
rptcmd.CommandTimeout = 150
Dim okrd As SqlDataReader = rptcmd.ExecuteReader()
