Sql - ADODB - how to get only the total number of records

In ADODB, you can use the RecordCount property to get the total number of records returned by a query. However, it's important to note that the RecordCount property may not always return accurate results depending on the cursor type and the provider being used.

Here's how you can retrieve the total number of records using ADODB in VBA:

Dim conn As Object Dim rs As Object Set conn = CreateObject("ADODB.Connection") Set rs = CreateObject("ADODB.Recordset") conn.Open "YourConnectionString" rs.Open "SELECT * FROM YourTable", conn If Not rs.EOF And Not rs.BOF Then ' Move to the last record to get the total count rs.MoveLast ' Get the total count MsgBox "Total number of records: " & rs.RecordCount Else MsgBox "No records found" End If rs.Close conn.Close Set rs = Nothing Set conn = Nothing

Replace "YourConnectionString" with your actual database connection string and "SELECT * FROM YourTable" with your SQL query.

In this code:

  • We open a connection to the database and execute the query.
  • If the recordset is not empty (Not rs.EOF And Not rs.BOF), we move to the last record using rs.MoveLast.
  • We then retrieve the total number of records using rs.RecordCount.
  • Finally, we close the recordset and connection objects.

Keep in mind that the accuracy of RecordCount can depend on various factors such as the cursor type, the provider being used, and whether the query retrieves a forward-only or static cursor. Therefore, it's always a good practice to test and verify the results, especially in a production environment.
