+Summary: SqlCommandBuilder creates incorrect Update and Delete commands
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+SqlCommandBuilder is supposed to create default update and delete commands
+based on a DataAdapter. The update command (and I think the delete command
+as well) is incorrect in the "where" clause.
+For regular columns which might be NULL, the usual clause is:
+    ((@p1 = 1 AND FOO IS NULL) OR (FOO = @P2 ) )
+The problem is that "@p1" gets set to the same value and type as @P2. For
+instance, for a VARCHAR column with value "XX", I see:
+   p1 = "XX" of type VARCHAR
+   p2 = "XX" of type VARCHAR
+It should be:
+   p1 = 0 of type INT
+   p2 = "XX" of type VARCHAR
+It looks like the author of the code got confused about the definition of
+"clause1" and "clause2" in the code, and those should be swapped. Also, the
+type of "p1" (in my example) needs to be set to INT.
+Steps to reproduce the problem:

+How often does this happen?
