我有以下查询,我可以为爱而没有钱在我的UPDATE
声明中找出错误的位置?我上周才开始玩这个游戏,所以我的学习曲线很大!
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
'Declerations For Calling on
Dim AnimalHouse As String
AnimalHouse = "TestText"
Dim AddressForAssingment As Integer
AddressForAssingment = 1
Dim IDCheckAssignment As Integer
IDCheckAssignment = 1
Dim CommandText As String = _
"UPDATE IOInformation.Description = @animalHouse, WHERE ID_number = @addrForAssn AND ID_Check = @Id;"

Dim myCommand As New OleDbCommand(CommandText)
myCommand.Parameters.AddWithValue("@animalHouse", AnimalHouse)
myCommand.Parameters.AddWithValue("@addrForAssn", AddressForAssingment)
myCommand.Parameters.AddWithValue("@Id", IDCheckAssignment)
myCommand.Connection = myConnection

您应该使用以下语法进行更新UPDATA tablename SET collumnName='value', columnname1='adsf' WHERE ...
,不要','在哪里。 UPDATE IOInformation SET Description = ... WHERE ID_number = ... AND ID_Check = ...;

您的语法中有几处错误。
UPDATE查询的正确语法是
UPDATE table SET field1=value1, field2=value2, ...... WHERE keyfield=value
所以你应该写
Dim CommandText As String = _
"UPDATE IOInformation SET Description = @animalHouse " &
"WHERE ID_number = @addrForAssn AND ID_Check = @Id;"
将表名与字段名分开,在第一个字段名之前添加SET,并在WHERE之前删除逗号

UPDATE IOInformation
SET Description = @animalHouse
WHERE ID_number = @addrForAssn
AND ID_Check = @Id
