How to replace the content of the current table in Excel?

In VB, to replace the contents of the current table, you can use the SqlCommand object and UPDATE statement in the ADO.NET library.

Firstly, you need to create a SqlCommand object and assign the UPDATE statement to it. The UPDATE statement is used to specify the table, columns, and new values to update.

Next, use the ExecuteNonQuery method of the SqlCommand object to execute an UPDATE statement, thus achieving the replacement operation on the current table content.

Here is a simple example code:

Imports System.Data.SqlClient

' 假设当前表名为"Table1"，要替换的列名为"Column1"，新的值为"NewValue"
Dim connectionString As String = "YourConnectionString"
Dim tableName As String = "Table1"
Dim columnName As String = "Column1"
Dim newValue As String = "NewValue"

Using connection As SqlConnection = New SqlConnection(connectionString)
    connection.Open()
    Dim sqlCommand As SqlCommand = New SqlCommand($"UPDATE {tableName} SET {columnName} = @newValue", connection)
    sqlCommand.Parameters.AddWithValue("@newValue", newValue)
    sqlCommand.ExecuteNonQuery()
End Using

Please note that the above code only demonstrates the operation of replacing the values in a specific column of the current table. If you need to replace more columns or table content, you can adjust the UPDATE statement and parameters accordingly.
