执行SQL时出错

Question

当我尝试执行下面的代码时,我收到以下错误.我已经添加了我传递的SQL字符串.我错过了什么？

错误:

查询表达式'TOURID = 25e5eed3-ea84-4c30-a660-2c880253da60'中的语法错误(缺少运算符)

我的查询,

DELETE * FROM TOURS WHERE TOURID = 25e5eed3-ea84-4c30-a660-2c880253da60;

我的代码,

Dim connectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\_Development\Data\filename.accdb;Persist Security Info=False;"
Dim DBConnection As New System.Data.OleDb.OleDbConnection(connectionString)
Try
    DBConnection .Open()
    Dim cmd As New System.Data.OleDb.OleDbCommand(sql, DBConnection )
    Dim sqlAdapterTOURS As New System.Data.OleDb.OleDbDataAdapter(cmd)
    cmd.CommandType = CommandType.Text
    cmd.ExecuteNonQuery()
Catch ex As Exception
    MessageBox.Show(ex.Message)
Finally
    DBConnection .Close()
End Try

Answer 1

使用GUIDS时需要引用如下:

DELETE * 
FROM TOURS 
WHERE TOURID = '25e5eed3-ea84-4c30-a660-2c880253da60';
