ADODB查询超时

Question

我正在尝试打开一个查询，该查询正在超时。我尝试过设置超时值属性，但它似乎不想接受它。

使用管理窗口( Server 2005)执行查询需要34秒钟，所以我知道我需要增加超时时间。

当前代码：

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

我也尝试过设置连接本身的超时( CurrentProject.Connection.CommandTimeout = 120 )，但是如果在这个命令之后查询值，它将保持为30。

连接属性：

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
Extended Properties = 
Cache Authentication = True
Encrypt Password = 
Persist Encrypted = 
Persist Security Info = False
Asynchronous Processing = 0
Connect Timeout = 600
Protection Level = 
Prompt = 4
Mode = 
Location = 
Locale Identifier = 1033
Impersonation Level = 
Window Handle = 
Data Source = MyServer
User ID = 
Password = 
Integrated Security = SSPI
Mask Password = 
Initial Catalog = MyDatabase
Lock Owner = 
Bind Flags = 
General Timeout = 0
Data Provider = SQLOLEDB.1
Autocommit Isolation Levels = 4096
Unique Reshape Names = False

Answer 1

不知道你是否已经解决了这个问题，但我也有同样的问题。我是用Recordset.Open SQL_String连接的。

在此之前，我只设置了timeout属性，不是在记录集或命令上，而是在Connection对象上：

Connection.CommandTimeout = 0

解决方案 还必须在正在使用的commandTimeout或ADODB.Recordset上设置ADODB.Command属性。否则，这些对象将使用30秒的默认时间限制，因为它们不会从关联的ADODB.Connection实例继承时间限制。 在ASP 3中使用VBScript的示例： set con = createObject("ADODB.Connection") con.open connectionString con.commandTimeout = 60 set con.commandTimeout= createObject("ADODB.Command") command.activeConnection =concommand.commandType= adCmdText command.commandText = sql command.commandTimeout = 60 command.execute response.write command.commandTimeout‘现在是60秒。

对于OLEDB，不需要指定连接的超时时间:-

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
