How can data in a table be modified in bulk using access?

You can use the following method to bulk modify table data:

1. You can use the UPDATE statement to make bulk changes to table data. Here is an example:

UPDATE 表名 SET 列名1=新值1, 列名2=新值2 WHERE 条件;

1. You can update table data based on data from other tables using UPDATE and JOIN joins. Here is an example:

UPDATE 表名1 INNER JOIN 表名2 ON 表名1.关联列 = 表名2.关联列 SET 表名1.列名 = 表名2.新值 WHERE 表名1.条件;

1. You can use VBA macros to bulk modify table data if you are familiar with VBA programming. Here is an example.

Sub 批量修改数据()
    Dim db As Database
    Dim rs As Recordset
    
    Set db = CurrentDb
    Set rs = db.OpenRecordset("SELECT * FROM 表名 WHERE 条件")
    
    Do Until rs.EOF
        rs.Edit
        rs!列名1 = 新值1
        rs!列名2 = 新值2
        rs.Update
        rs.MoveNext
    Loop
    
    rs.Close
    Set rs = Nothing
    Set db = Nothing
End Sub

Please choose the method that best suits your specific needs to make bulk changes to table data.
