(2) Use the following event process: Private Sub statistics_click () Dim dbs As Database, qdf As QueryDef Dim tmq As Dynaset Dim strSQL As String Set dbs = CurrentDb 'Open the pass query stat_query created above.

Another Stored Procedure Code for reading data. (2) Use stored procedures Then we can call these stored procedures in the ASP program. Here we can see why the query in Access is its Stored procedure-the CommandType attribute of

using Hotmail to send an email, we submit a POST request, as shown in the sendmail () method below. /// First, prepare the quotation marks and the time mark of the email: // Quote string quote = "\ u0022"; // time mark datetime now = datetime. now; string timestamp = now. tostring ("DDD, DD Mmm yyyy hh: mm: SS "); Httpmail uses a communication mode similar to SMTP. Outlook Express uses the MIME format to send emails. In this example, only plain

However, it is slow to process a large amount of data. When a large amount of data needs to be processed, it cannot be processed on the client, but must be processed on the server. However, access and server are mostly connected through ODBC, which increases the difficulty of calling backend stored procedures. Through long-term exploration in practical work, I can use the following three methods to call the

We are already familiar with using ASP to call SQL Server Stored Procedures to perform database operations. But do you know that in table-level database access, we can also create and use stored procedures "? Access + ASP is an excellent combination of lightweight Web applications: simple, fast, and compatible, but the performance is usually not high. In addition
