If there is a foreign key on a row and a child row is deleted, the deleted row
|
|
is attempted to be read setting EnforceConstraints to false and then true.
|
|
|
|
|
|
Reproducible: Always
|
|
|
|
Steps to Reproduce:
|
|
1. Create a foreign key constraint.
|
|
2. Add a parent row and a child row.
|
|
3. childRow.AcceptChangs(); cihldRow.Delete();
|
|
4. EnforceConstraints = false; EnforceConstraints = true;
|
|
|
|
Actual Results:
|
|
A DeletedRowInaccessibleException is raised
|
|
|
|
Expected Results:
|
|
An exception should not be raised
|
|
|
|
Test case to reproduce
|
|
----------------------
|
|
|
|
DataSet data = new DataSet();
|
|
DataTable parent = new DataTable("parent");
|
|
DataColumn pk = parent.Columns.Add("PK");
|
|
DataTable child = new DataTable("child");
|
|
DataColumn fk = child.Columns.Add("FK");
|
|
|
|
data.Tables.Add(parent);
|
|
data.Tables.Add(child);
|
|
data.Relations.Add(pk, fk);
|
|
|
|
parent.Rows.Add("value");
|
|
child.Rows.Add("value");
|
|
data.AcceptChanges();
|
|
child.Rows[0].Delete();
|
|
parent.Rows[0][0] = "value2";
|
|
|
|
data.EnforceConstraints = false;
|
|
data.EnforceConstraints = true;
|
|
|
|
Proposed fix
|
|
------------
|
|
|
|
Add line
|
|
if (row.RowState == DataRowState.Deleted) continue;
|
|
|
|
to
|
|
|
|
internal override bool IsConstraintViolated()
|
|
{
|
|
if (Table.DataSet == null || RelatedTable.DataSet == null)
|
|
return false;
|
|
|
|
bool hasErrors = false;
|
|
foreach (DataRow row in Table.Rows) {
|
|
// first we check if all values in _childColumns place are nulls.
|
|
// if yes we return.
|
|
--> if (row.RowState == DataRowState.Deleted) continue; // LINE
|
|
ADDED
|
|
|
|
if (row.IsNullColumns(_childColumns))
|
|
continue;
