Syntax error in UPDATE statement. ?
-
hello, i have a Datalist and ACCESS DataBase, im using the update event in datalist to update two fields in my db. first one is subj the second is text. i get the Syntax error in update statement all the time while updating. the primary key is my ID field in the db, and it was set to be the same in the datalist. this is the C# code for the update method:
protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)
{
Label lblsubj = (Label)e.Item.FindControl("lblsubj");
string st = lblid.Text;
TextBox txtBoxId = (TextBox)e.Item.FindControl("txtBoxId");
TextBox txtBoxTitle = (TextBox)e.Item.FindControl("txtBoxTitle");
TextBox txtBoxFile = (TextBox)e.Item.FindControl("txtBoxFile");
TextBox txtBoxText = (TextBox)e.Item.FindControl("txtBoxText");
string queryStr = "UPDATE news SET subj='" + txtBoxTitle.Text + "', ";
queryStr += "text='" + txtBoxText.Text + "', ";
queryStr += "WHERE id='" + st + "'";string connectionStr = @"Provider=Microsoft.Jet.OleDb.4.0;Data Source=" + Server.MapPath("~/App\_Data/db.mdb"); OleDbConnection connectObj = new OleDbConnection(connectionStr); OleDbCommand cmd = new OleDbCommand(queryStr, connectObj); connectObj.Open(); cmd.ExecuteNonQuery(); connectObj.Close(); this.DataList1.EditItemIndex = -1; BindTheDataList(); }And this is my ASPX page code:
<asp:DataList ID="DataList1" runat="server" DataKeyField="subj" Height="96px"
OnCancelCommand="DataList1_CancelCommand" OnDeleteCommand="DataList1_DeleteCommand"
OnEditCommand="DataList1_EditCommand" OnUpdateCommand="DataList1_UpdateCommand"
Style="position: static" Width="641px">
<EditItemStyle BackColor="DarkGray" ForeColor="Black" />
<EditItemTemplate>
<table id="TABLE1" language="javascript" onclick="return TABLE1_onclick()">
<tr>
<td style="width: 90px">
Editing item:
<asp:Label ID="lblid" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"id") %>'
Visible="False"></asp:Label></td>WHERE id='4' is your ID column type is a VAR/NVARcher type ? MyDevBank.com

This should do the trick;
UPDATE news
SET subj='aasda22'
,[text]='sdasd'
WHERE id='4'"Text" should be avoided as a column-name; it's a reserved word.
