通过使用OleDb操作Oracle数据库，成功实现图片上传到Blob类型的字段，但有时会发生ORA-01036错误的问题，经查询是错误提示为illegal variable name/number，不知道有谁能详细解释illegal variable name/number的意思
Oracle Data Provider for .NET
Hi
I am using ODP.NET (Oracle Data Provider for .NET) in my asp.net application.
I have a table in my oracle database called "equipmentgroup". When the page loads for the first time i retrieve all the records from the table to a dataset and save it to viewstate. Later on any addition or modification is done in the dataset only in disconnected mode. Finally,when user clicks update i call this function "update" which should do a batch update but instead it gives the following error :
"ORA-01036: illegal variable name/number "
private void update()
{
OracleParameter workParam; OracleConnection cnn = new OracleConnection("Data Source=NEELESHR;User Id=tmse; Password=tmse;"); string sql = "INSERT INTO EquipmentGroup (Code, Description, LifeTime, PriamryLife, Grading, Inflator, ExtensionRate, MaintenanceFee) VALUES (:Code, :Description, :LifeTime, :PriamryLife, :Grading, :Inflator, :ExtensionRate, :MaintenanceFee)"; OracleCommand cmd = new OracleCommand(sql,cnn); cmd.CommandType = CommandType.Text; OracleDataAdapter da = new OracleDataAdapter(); da.InsertCommand = cmd; workParam = da.InsertCommand.Parameters.Add("Code",OracleType.Char,10,"Code"); workParam.SourceVersion = DataRowVersion.Current; workParam = da.InsertCommand.Parameters.Add("Description",OracleType.VarChar,50,"Description"); workParam.SourceVersion = DataRowVersion.Current; workParam = da.InsertCommand.Parameters.Add("LifeTime",OracleType.Number); workParam.SourceColumn = "LifeTime"; workParam.SourceVersion = DataRowVersion.Current; workParam = da.InsertCommand.Parameters.Add("PriamryLife",OracleType.Number); workParam.SourceColumn = "PriamryLife"; workParam.SourceVersion = DataRowVersion.Current; workParam = da.InsertCommand.Parameters.Add("Grading",OracleType.Char,10,"Grading"); workParam.SourceVersion = DataRowVersion.Current; workParam = da.InsertCommand.Parameters.Add("Inflator",OracleType.Number); workParam.SourceColumn = "Inflator"; workParam.SourceVersion = DataRowVersion.Current; workParam = da.InsertCommand.Parameters.Add("ExtensionRate",OracleType.Number); workParam.SourceColumn = "ExtensionRate"; workParam.SourceVersion = DataRowVersion.Current; workParam = da.InsertCommand.Parameters.Add("MaintenanceFee",OracleType.Number); workParam.SourceColumn = "MaintenanceFee"; workParam.SourceVersion = DataRowVersion.Current; try
{ da.Update(ds,"EquipmentGroup");
} catch(Exception e) { Message.Text = e.Message; }
}Hi,I think that you should add parameters with ":" included, like:workParam =da.InsertCommand.Parameters.Add(":Code",OracleType.Char,10,"Code");OleDb Data Provider for .NETstring sql = "INSERT INTO EquipmentGroup (Code, Description, LifeTime, PriamryLife, Grading, Inflator, ExtensionRate, MaintenanceFee) VALUES (?, ?, ?, ?, ?, ?, ?, ?, )";Hi,I think that you should add parameters with ":" included, like:workParam =da.InsertCommand.Parameters.Add(":Code",OracleType.Char,10,"Code");
