(?,?,?) 附近的 SQL 语法错误

Question

I surf the net and don't search what I need. So please you help me. When I try to execute this SQL statement in Eclipse

private final String INSERT_ = "INSERT INTO department VALUES (?, ?, ?)";

I have next error:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?, ?, ?)' at line 1 This is my code

public void insert(int id, String name, String description) throws SQLException
{
    Department result = null;
    Connection conn = ConnectionManager.getConnection();
    PreparedStatement stmt = conn.prepareStatement(INSERT_);
    stmt.setInt(1, id);
    stmt.setString(2, name);
    stmt.setString(3, description);
    stmt.executeUpdate(INSERT_);
    System.out.println("Record is inserted into table!");
}

Thanks in advance!

Answer 1

You shouldn't pass the SQL String to executeUpdate , since your PreparedStatement was already initialized with the SQL String + the parameters.

Change

stmt.executeUpdate(INSERT_);

to

stmt.executeUpdate();
