Question

 Public Shared Function GetData(ByVal id As Integer) As List(Of SomeClass)
            Dim command As New OracleCommand       
            Dim conn As New OracleConnection(WebConfigurationManager.ConnectionStrings("ConnectionString").ToString)
            Dim param As New OracleParameter
            param.ParameterName = "idnumber"
            param.Value = id
            param.DbType = DbType.Int32
            command.Parameters.Add(param) 

            command.Connection = conn
            command.CommandText = "select VAL1, VAL2, Year from local.proc where id = :idnumber and Year = to_number(to_char(sysdate,’YYYY’))"

            Dim reader As OracleDataReader
            Dim someList As New List(Of SomeClass)

            connection.Open()
            reader = command.ExecuteReader()
            While reader.Read
                Dim someClass As New SomeClass
                someClass.VAL1 = reader("VAL1")
                someClass.VAL2 = reader("VAL2")
                someClass.Year = reader("YEAR")
                someList.Add(someClass)
            End While
            connection.Close()
            Return someList
        End Function

此函数提供ORA-00911无效字符错误。我有其他相同风格的方法，这些方法正常运行。有关我在哪里出错的建议吗？感谢

Answer 1

我认为问题在于年度SQL语句中的引号错误，即：’YYYY’

将其更改为'YYYY'

替换行：

command.CommandText = "select VAL1, VAL2, Year from local.proc where id = :idnumber and Year = to_number(to_char(sysdate,’YYYY’))"

与

command.CommandText = "select VAL1, VAL2, Year from local.proc where id = :idnumber and Year = to_number(to_char(sysdate,'YYYY'))"

Answer 2

看起来您正在使用格式化的撇号。

to_char(sysdate,’YYYY’

尝试将其更改为

to_char(sysdate,'YYYY'

VB.net函数给ORA-00911无效字符错误
