11
+You can change the data source for individual reports by overriding the [[PreExecuteReportSet|/FAQ/PreExecuteReportSet]] method. Here is the source code for changing data sources:
12
+
13
+```
14
+public override void PreExecuteReportSet(Izenda.AdHoc.ReportSet reportSet)
15
+{
16
+ base.PreExecuteReportSet(reportSet);
17
+ string orig = reportSet.Source;
18
+ string target = "[dbo].[Orders2]";
19
+
20
+ if(!orig.Contains("Orders")) {
21
+ return; //check for strings like "Orders". If that's not found, we return.
22
+ }
23
+ foreach (JoinedTable jt in reportSet.JoinedTables)
24
+ {
25
+ jt.TableName = jt.TableName.Replace(orig, target);
26
+ }
27
+ foreach (Report r in reportSet.Reports.AllValues)
28
+ {
29
+ foreach (Field f in r.Fields)
30
+ {
31
+ f.ColumnName = f.ColumnName.Replace(orig, target);
32
+ }
33
+ }
34
+
35
+ foreach (Filter f in reportSet.Filters)
36
+ {
37
+ f.Column = f.Column.Replace(orig, target);
38
+ }
39
+}
