Question

我正在使用sql developer / Oracle Server

在vb.net中进行审计跟踪

当我构建解决方案时，我得到5个值

的错误“参数未指定参数”

任何帮助将不胜感激

这是代码

Public Sub UserLog(ByVal Userlevel As String, ByVal FirstName As String,
                ByVal LastName As String, ByVal Time As Integer,
                ByVal Action As String)
    Try
        Dim queryLog As String = "INSERT * TBL_LOG where USERLEVEL = (USERLEVEL,FIRSTNAME,LASTNAME,TIME,ACTION) VALUES ( '" & Userlevel & "', '" & FirstName & "', '" & LastName & "', '" & Time & "', '" & Action & "') "

        Dim connStr As String = ConstantsPub.connectionStr
        Dim query As String = queryLog
        Dim conn As New OracleConnection(connStr)
        Dim da As OracleDataAdapter = New OracleDataAdapter
        Dim ds As New DataSet()
        conn.ConnectionString = connStr
        conn.Open()
        da.SelectCommand = New OracleCommand(query, conn)

    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try

End Sub

您的INSERT语句不正确;它的格式应该是这样的：

INSERT INTO table_name (column1,column2,column3,...)
VALUES (value1,value2,value3,...);

但是，如果您想要从另一个表中将值插入TBL_LOG表，则需要使用INSERT INTO SELECT语句，其格式如下：

INSERT INTO table2 (column_name(s)) SELECT column_name(s) FROM table1;

vb.net制作审计跟踪并检索值
