View 2 RepliesI would like to know, how to set up the Entity framework to create a nvarchar(50) insted of a nvarchar(4000), when creating a string? by the way I am not using the designer!
View 6 RepliesDoes it make a difference in terms of the actual size of the database if I define one of the columns as nvarchar(100)? If there are restrictions on the form as for how much you can input, let's say 50 characters, does the db save blank spaces from character 51-100 and create a database that is larger than it would be it the column was defined as nvarchar(50)?
View 2 RepliesMy datatable consists of a column named "ID". The no. of values in this column varies.Sometimes this Datatable fetches 3 IDs in that ID column, sometimes 2. Now if for example, my datatable has three values as 1,2,3. What I want is to put these three values in a string and separate them by commas as folows:-
string test= "1,2,3";
If Datatable has 2 values, then string should be as follows:-
string test= "1,2";
I did try but in vain.
edit:-
DataTable dt=new DataTable;
dt = obj.GetIDs();
for (int i = 0; i < dt.Rows.Count; i++)
{
string test= "What should be here????";
}
edit 2
foreach(DataRow dr in dt.Rows)
{
string str = str + "," + Convert.ToString(dr("ID"));
}
@Rajeev ::Tried this..it says dr is a variable but used as a method. What's wrong?

I am using a viewstate to store the company Ids and splitting at hyphen.
protected void onCompanychange(object sender, EventArgs e) {
ViewState["companyID"] += companydropdown.SelectedValue + "-";
String companyids = ViewState["companyID"].ToString();
string pattern = "-";
company_array = Regex.Split(companyids, pattern);
company_length = company_array.Length;
}
Company array is a string array where i have stored the company ids
the problem is company_array[0] has the initial value of the dropdownlist(company) --select company which is why m getting the error(cannot convert data type nvarchar to int) . I have used the same logic in many places in my project it did not give any error.
int count = 0;
company_length = company_length - 1;
while (count < GridView3.Rows.Count && compid_counter < company_length ) {
cmd = new SqlCommand("insertWorkDetais", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@trainerId",trainerID);

View 1 RepliesI have 1,2,3,4,5,6,7,8,9 stored as nvarchar inside Level in my db.
I then have a dropdownlist with values 1,2,3,4,5,6,7,8,9. When a user makes a selection (i.e 1) (Level.SelectedValue.ToString). This builds an sql query via a param like this:
"Select things From MBA_EOI Where level = 1"
When I run the select I get the following error:
Syntax error converting the nvarchar value '1,2,3,4,5,6,7,8,9' to a column of data type int.
I was under the impression that I was dealing with an Nvarchar field and the selected value as string, where does the int conversion come in?
p.s I have also tried Level.SelectedItem.ToString
