Literal does not match format string

Question

I am trying to insert data in oracle express 10 g table.

My table contains following Columns:

Field Name                           Data Type

 ATDATE                               DATE
 ATTIME                               VARCHAR2(5)
 EMPNO                                NUMBER(8)
 INOUTIND                             CHAR(1)
 TRTNO                                CHAR(3)
 FLAG                                 NUMBER(2)
 STATUS                               CHAR(1)
 LUPDT                                DATE

Now when I am trying to insert data from my C# Windows application I am getting error

ORA-01861 : literal does not match format string"

So how can I solve it?

I am writing insert command in the Form itself using OracleCommand.

---

OracleCommand cmd = new OracleCommand("INSERT INTO TMPATND values(:Atdate,:Attime,:Empno,:Inoutind,:Trtno,:Flag,:Status,:Lupdt)", con); 

:Atdate,:Attime etc are parameters. e.g: cmd.Parameters.AddWithValue(":Atdate","20120103");

In which format I should pass the date? ( dd/mm/yyyy or yyyymmdd or others)

Answer 1

If you perform the insert using parameters, you won't have to worry about the format of the string.

However, if that is not an option, you can use:

myDate.ToString("dd-MMM-yy").ToUpper()
