Java：如何在sql查询中使用多个参数在jdbc中执行prepareStatement？

Question

This is what I want to do:

PreparedStatement query2 = 
conn.prepareStatement ("UPDATE report SET Name = ? WHERE Id = ?");

String blah = "Jane";
int id = 1;

query2.setString(1, blah);
query2.setInt(2, id);
query2.executeQuery();

But I'm getting this error:

The statement did not return a result set.

I am new to the whole jdbc world. Where am I going wrong here?

Answer 1

You should use executeUpdate .

"Executes the given SQL statement, which may be an INSERT, UPDATE, or DELETE statement or an SQL statement that returns nothing, such as an SQL DDL statement."
