Question

搜索和搜索，修改并尝试了所有解决方案，但没有任何作用。

错误：

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'stocktick' in 'field list'

表：

"CREATE TABLE portfolio (" 
        + "idNum INT NOT NULL AUTO_INCREMENT,"  
        + "stocktick VARCHAR(255),"
        + "stock VARCHAR(255),"
        + "ask DOUBLE(10,2), "
        + "bid DOUBLE(10,2), "
        + "amount INT,"
        + "fundsafter DOUBLE(10,2),"
        + "lastact VARCHAR(255),"  
        + "PRIMARY KEY(idNum))";

INSERT查询：

public void stockPurchase(String stockCode, String stockAmount){
    spent = amountInt;
    funds = funds - spent;

    LocalDate date = LocalDate.now();
    System.out.println(date.toString());
    System.out.println(stockAmount);
    System.out.println(stockCode);
    System.out.println(words[0]);

    try {
        //Get a connection to DB:

        Connection con = DriverManager.getConnection(dbUrl, name, pw);

        prepSt = con.prepareStatement("INSERT INTO portfolio (stocktick, stock, ask, bid, amount, fundsafter, lastact)"
                + " VALUES (?, ?, ?, ?, ?, ?, ?)");

        //Set the parameters:
        prepSt.setString(1, stockCode);
        prepSt.setString(2, words[0]);
        prepSt.setDouble(3, Double.parseDouble(words[1]));
        prepSt.setDouble(4, Double.parseDouble(words[2]));
        prepSt.setInt(5, Integer.parseInt(stockAmount));
        prepSt.setDouble(6, funds);
        prepSt.setString(7, date.toString());

        prepSt.executeUpdate();

        System.out.println("Insert Complete");

    } catch (SQLException e) {

        e.printStackTrace();
    }

    fundsLabel.setText("Funds: $" + (funds));
    userPanel.remove(bpAction);
    userPanel.remove(seAction);
}

所谓的方法：

stockPurchase(stock.getText(), amount.getText());

一切正常，直到我进入我的INSERT声明，特别是＆＃39; stocktick＆＃39;。即使我向其中输入一个简单的字符串或尝试用引号括起该字符串，它也会产生此错误。哪里哪儿我错了？
