Hello I'm having problem with updating datatypes
I insert the date in the C# part like this
string strSQL = "INSERT into Frettir (CreatedBy,CreatedOn,Title,Description,Starts,Ends,CatId,SectionId,ArticleExt,Myndatexti,MyndUrAlbumi,NrMyndar) values(?,?,?,?,?,?,?,?,?,?,?,?)";
cmd.Parameters.Add("@Starts",OleDbType.Date).Value = dstartdate;
but I update in the aspx part like this
UpdateCommand="UPDATE [Frettir] SET [Title]=@Title,[Description]=@Description,[CreatedBy]=@notandaID,[ArticleExt]=@ArticleExt, [Myndatexti]=@Myndatexti,[Starts]=@Starts WHERE [ArticleID]=@id2 "
<UpdateParameters>
<asp:Parameter Name="Title" Type="String" />
<asp:Parameter Name="Description" Type="String" />
<asp:Parameter Name="notandaID" Type="int16" />
<asp:Parameter Name="ArticleExt" Type="String" />
<asp:Parameter Name="Myndatexti" Type="String" />
<asp:Parameter Name="Starts" Type="DateTime" />
<asp:QueryStringParameter Name="id2" QueryStringField="ArticleID" Type="Int32" />
</UpdateParameters>
I get an error Data type mismatch in criteria expression It seems that there are some type differences between the type that is input in the c# part and the aspx-part
Can anyone help me with this?
回答1:
I just did it once... I assigned the valued using the following code..
com.Parameters.AddWithValue("EmpDoj", EmpDoj.ToShortDateString());
It worked for me.. Thought it could help you as well...
Further, I'm eager to know the answer, why yours was not working...
