DbUtil Class

This class provides a small set of static methods for extracting array data from database tables. See the tutorial on aggregating data for some worked examples.

public class DbUtil

DbUtil Methods

GetIntegers
GetDoubles
GetStrings

Example


 sp.Reset(240,160);
 sp.SetMargins(24,18,24,4);
 filler = (int)sp.MissingValue;
 
 mytable = new DataTable(); // Get some real data here!;
 myselection = mytable.Select("year>2006 AND symb='BP'");
 int[] BP = DbUtil.GetIntegers(myselection,filler,"SharePrice");
 
 sp.Heading = "BP";
 sp.HeadingStyle = HeadingStyles.Right;
 sp.DrawLineGraph(BP);

This example simply retrieves one complete column from the current selection, using SharpPlot’s missing value setting to replace any DBNull values in the data.

Requirements

Namespace: Causeway

Assembly: SharpPlot (in sharpplot.dll)
