Question

I have this query:

SELECT COUNT(*) From Employees

I execute the query and have this:

    public static int GetNumJobs()
{
    clsJobPosting JobPosting = new clsJobPosting();
    DataSet dsJobs = JobPosting.GetNumRows();
    DataTable dtJobs = dsJobs.Tables[0];
    return Convert.ToInt32(dtJobs.Rows[0]);
}

GetNumRows() returns the dataset, I want to return the number of rows from this query, how can I accomplish this?

Answer 1

try changing this

return Convert.ToInt32(dtJobs.Rows[0]);

to this

return Convert.ToInt32(dtJobs.Rows[0][0]);

Also, why are you returning a DataSet from JobPosting.GetNumRows()? You should return an int there so you don’t have to repeat the same logic all over your code.
