Hello

I created a web site that my users will be able to put in trouble tickets to. Part of this is the date and time they put it in and then the date and time the tech got back to them and then the Resolution date. I need to be able to do a date difference between them. but when I make the SQL database a date field I get a error when I submit the page. The error is as follows. Help would be greatly appreciated.

Error inserting record. Syntax error converting datetime from character string.

try in this way

insertSQL = "INSERT INTO dbo.FinMain (";
        insertSQL += "StartDate, Vzid, FName, LName, Location, Phone, MachineName, Problem, ResolutionDate) ";
        insertSQL += "VALUES ('";
        insertSQL += DateTime.Now.ToShortDateString() + " " + DateTime.Now.ToShortTimeString().Replace(".",":") + "', '";
        insertSQL += txtBoxVZID.Text + "', '";
        insertSQL += txtBoxFName.Text + "', '";
        insertSQL += txtBoxLName.Text + "', '";
        insertSQL += ddlLocation.SelectedItem + "', '";
        insertSQL += txtBoxPhone.Text + "', '";
        insertSQL += txtBoxMachName.Text + "', '";
        insertSQL += ddlProblem.SelectedItem + "', '";
        insertSQL += "0" + "')";

I believe the issue is caused when the value "0" is inserted into a table column that is defined as a Date/Time type.  It probably can't convert the "0" string to a valid date.  If that is the case, you may want to alter the table definition to allow NULL's in the ResolutionDate column.

[ResolutionDate] [datetime] NULL

When the issue is resolved, you'd run your UPDATE SQL statement that will replace the null value in ResolutionDate with a date value.

If you are inserting new records, is it not the case that there is no Resolution date for that new record?  If that is true, then simply do NOT assign a resolutionDate value (see below)
as suggested above, allow the ResolutionDate field to accept a NULL, and you should be 'good to go'
