Hi, I called PreparedStatement.executeUpdate, passed in a delete statement which delete one row. It succeed, but it return 0. I've checked the database and it's really deleted. This delete statement is just a very simple sql statement that use one where condition. Then I try to change the statement to delete something in other table, still the same database, in that same code, and it return the correct row count. What is the possibility of this problem?
