ADODB query timeout

问题:

I am trying to open a query, which is timing out. I have tried setting the timeout property, but it doesn't seem to want to accept it.

The query takes 34 seconds to execute using MS-SQL Server Management window (SQL Server 2005), so I know I need to increase the timeout.

Current code:

Public Function retRecordSet(StrSQL)
Dim cmd ' as new ADODB.Command
Dim rs 'As New ADODB.Recordset

Set cmd = CreateObject("ADODB.Command")
Set rs = CreateObject("ADODB.Recordset")

cmd.ActiveConnection = CurrentProject.Connection
cmd.CommandText = StrSQL
cmd.CommandTimeout = 0
Set rs = cmd.Execute

Set retRecordSet = rs
End Function

I have also tried setting the timeout of the connection itself CurrentProject.Connection.CommandTimeout = 120, but if I query the value right after this command, it remains at 30

Connection properties:

Provider=Microsoft.Access.OLEDB.10.0;Persist Security Info=False;Data Source=MyServer;Integrated Security=SSPI;Initial Catalog=MyDatabase;Data Provider=SQLOLEDB.1

Data Source Object Threading Model = 1
Multiple Results = 3
Multiple Parameter Sets = False
SQL Support = 283
Catalog Location = 1
Catalog Term = database
Catalog Usage = 15
Rowset Conversions on Command = True

Persist Security Info = False

Not sure if you already got over the problem but I had the same issue. I'm doing it with Recordset.Open SQL_String, Connection.

And before that I just set the timeout property, not on the Recordset or Command but on the Connection object:

Connection.CommandTimeout = 0

The Solution

You must also set the commandTimeout property on the ADODB.Command or ADODB.Recordset being used. Otherwise those objects will use the default time limit of 30 seconds because they do not inherit the time limit from the associated ADODB.Connection instance.

Example Using VBScript in ASP 3:

set con = createObject("ADODB.Connection") con.open connectionString con.commandTimeout = 60 set command = createObject("ADODB.Command") command.activeConnection = con command.commandType = adCmdText command.commandText = sql command.commandTimeout = 60 command.execute response.write command.commandTimeout 'This is now 60 seconds.

For OLEDB do you not need to specify the timout on the connection :-

Provider=Microsoft.Access.OLEDB.10.0;Persist Security Info=False;Data Source=MyServer;Integrated Security=SSPI;Initial Catalog=MyDatabase;Data Provider=SQLOLEDB.1;Connect Timeout=30
