使用ADO
dim cn as adodb.connection
dim cmd as adodb.command
dim rs as adodb.resultset
Set cn = New ADODB.Connection
With cn
.CursorLocation = adUseClient
.ConnectionString = gstrConnectionString
.Open
End With
Set adoCommand = New ADODB.Command
With adoCommand
.ActiveConnection = gadoConnection
.CommandType = adCmdStoredProc
.CommandText = "<stored proc name>"
Set adoRS = .Execute()
adoRS.CacheSize = 100
End With
for SQL Server the connection string would look something like the following:
Provider=SQLOLEDB.1;Password=<password>;Persist Security Info=True;User ID=<username>;Initial Catalog=<db_name>;Data Source=<servername>
使用DAO方式
