In your code fragment, a data set is always empty. No need to check it up.

I'm having an error each time the table is empty

Most likely, you are talking about exceptions, not error.
You do some mistake assuming the data set is not empty. If you show me the line where the exception is thrown, I'll tell you what is your mistake.

Like in your SqlDataAdapter.Fill. Look at this sample from http://msdn.microsoft.com/en-us/library/y4b211hz%28v=vs.110%29.aspx:

DataSet dataset = new DataSet();
dataset.Tables.Add("aaa");
dataset.Tables.Add("AAA");
adapter.Fill(dataset, "aaa"); // Fills "aaa", which already exists in the DataSet.
adapter.Fill(dataset, "Aaa"); // Adds a new table called "Aaa"

Compare with your code. What's do you think is its meaning?

Solution 2

ASM

DataSet ds = new DataSet();
da.Fill(ds, "Apprs_Mast");

Check the dataset default table rows count

if(ds.tables[0].rows.count>0)
{
//Implement your logic if rows are present
}
else
{
//exit if there is no rows
return;
}
