java - 在 '? WHERE Reg = ?' 附近使用的正确语法

Question

public static void updateData(Connection con, String make, String reg) {
    String selectString = "UPDATE Cars SET Make = ? WHERE Reg = ?";
    try
    {
        PreparedStatement pStmt = con.prepareStatement(selectString);
        pStmt.setString(1, make);
        pStmt.setString(2, reg);
        pStmt.executeUpdate(selectString);
        pStmt.close();

    }...

这段代码出现以下错误:

SQL Exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '? WHERE Reg = ?' at line 1

如果有人能帮助我，我将不胜感激。我四处搜索，但我的问题与我找到的解决方案完全不同。

Answer 1

使用用于PreparedStatements的重载executeUpdate

pStmt.executeUpdate();
