SQL Server timeout expired

Hello,

I got this error:

Execute OLE error code:80040E31 in Microsoft OLE DB Provider for SQL
Server
Timeout expired HRESULT error code:0x80020009 Exception occurred.

Here is my code -

connection_string << “CommandTimeout=0”
@connection = WIN32OLE.new(‘ADODB.Connection’)
@connection.ConnectionTimeout = ‘0’
@connection.Open(connection_string)

Please help! Thank you very much in advance!!!
