SQLITE Error E/SQLiteLog: (1) near "monthly": 语法错误

Question

您好，我收到一条 SQL 错误提示 E/SQLiteLog：（1）接近“每月”：语法错误

我相信这可能与我的 create Table 语句有关

  private static final String CREATE_TABLE2 = "CREATE TABLE " + TABLE_NAME2 + " (" + UID +
        " INTEGER PRIMARY KEY AUTOINCREMENT, " + POST_CODE + " VARCHAR(255)," + FIRST_LINE +
        " VARCHAR(255)," + TOWN + " VARCHAR(255)," + COUNTY + " VARCHAR(255)," + ROOM_NO +
        " INTEGER ," + ASKING_PRICE + " INTEGER ," + CURRENT_OFFER + " INTEGER ," + AGREED_PRICE +
        " INTEGER ," + AGENT_NAME + " VARCHAR(255)," + AGENT_PHO_NUM + " VARCHAR(255)," + ESTATE_AGENT_NAME +
        " VARCHAR(255), " + REFURB_COST + " VARCHAR(255), " + TIME_OF_APPOINTMENT + " VARCHAR(255), "
        + DONE_UP_VALUE + " INTEGER ," +WEEKLY_ROOM_RATE+ " INTEGER ," +EXPECTED_RENT + " INTEGER ," + MAX_OFFER + " INTEGER ,"
        + DISCOUNT_PERCENT + " DECIMAL(3,2) ," + LOAN_TO_VALUE + " DECIMAL(3,2) ,"+ MORTGAGE_Interest + "DECIMAL(3,2) ," +
        MAX_MORTGAGE + " INTEGER ," + DESPOSIT_NEEDED + " INTEGER ," + DESPOSIT_REPAYMENT_MONTHLY+ " INTEGER ," + REPAYMENT_ANNAUL + " INTEGER ,"
        +STAMP_DUTY_PER + " DECIMAL(3,2) ," + STAMP_DUTY_ACT + " INTEGER ," +INSURENCES+ " INTEGER ," + TOTAL_PURCHASE_COSTS +
        " INTEGER ," + TOTAL_MONEY_NEEDED + " INTEGER ," + MORTGAGE_REPAYMENT + " INTEGER ," +
        BILLS_UTILS + " INTEGER ," + TOTAL_COST_PER_MONTH + " INTEGER ," + TOTAL_REFURB_COST + " INTEGER ," + TOTAL_PROJECT_COST +
        " INTEGER ,"+ TOTAL_PROFIT + " INTEGER ,"+ RENTAL_PROFIT + " INTEGER);";

这是我添加到我的数据库的 insertData 方法

public long insertData2(String posCode, String firstLine, String town, String county, int roomNum,
                       int askingPrice, int currentOffer, int agreedPrice, String agentName,
                       String agentPhone, String estateAgentNam, int refurb, String Time, int doneUp,int expectedRent
                        , int weeklyRent, int maxOffer,double discountPercent, double LoanToValue,Double mortgageInterest
                        , int maxMOrtgage , int despositNeeded, int despositRepayment, int despositRepaymentAnnual, double stampDutyPer,
                       int stampDutyAct , int insurances, int totalPurchaseCost,int moneyNeeded, int mortgageRepayments,int billsUtils,
                       int costPerMonth, int refurbCost , int projectCost, int totalProfit, int rentProfit) {

    ContentValues contentValues = new ContentValues();
    contentValues.put(POST_CODE, posCode);
    contentValues.put(FIRST_LINE, firstLine);
    contentValues.put(TOWN, town);
    contentValues.put(COUNTY, county);
    contentValues.put(ROOM_NO, roomNum);
    contentValues.put(ASKING_PRICE, askingPrice);
    contentValues.put(CURRENT_OFFER, currentOffer);
    contentValues.put(AGREED_PRICE, agreedPrice);
    contentValues.put(AGENT_NAME, agentName);
    contentValues.put(AGENT_PHO_NUM, agentPhone);
    contentValues.put(ESTATE_AGENT_NAME, estateAgentNam);
    contentValues.put(REFURB_COST, refurb);
    contentValues.put(TIME_OF_APPOINTMENT, Time);
    contentValues.put(DONE_UP_VALUE,doneUp);
    contentValues.put(WEEKLY_ROOM_RATE,weeklyRent);
    contentValues.put(EXPECTED_RENT,expectedRent);
    contentValues.put(MAX_OFFER,maxOffer);
    contentValues.put(DISCOUNT_PERCENT,discountPercent);
    contentValues.put(LOAN_TO_VALUE,LoanToValue);
    contentValues.put(MORTGAGE_Interest,mortgageInterest);
    contentValues.put(MAX_MORTGAGE,maxMOrtgage);
    contentValues.put(DESPOSIT_NEEDED,despositNeeded);
    contentValues.put(DESPOSIT_REPAYMENT_MONTHLY,despositRepayment);
    contentValues.put(REPAYMENT_ANNAUL,despositRepaymentAnnual);
    contentValues.put(STAMP_DUTY_PER,stampDutyPer);
    contentValues.put(STAMP_DUTY_ACT,stampDutyAct);
    contentValues.put(INSURENCES,insurances);
    contentValues.put(TOTAL_PURCHASE_COSTS,totalPurchaseCost);
    contentValues.put(TOTAL_MONEY_NEEDED,moneyNeeded);
    contentValues.put(MORTGAGE_REPAYMENT,mortgageRepayments);
    contentValues.put(BILLS_UTILS,billsUtils);
    contentValues.put(TOTAL_COST_PER_MONTH,costPerMonth);
    contentValues.put(TOTAL_REFURB_COST,refurbCost);
    contentValues.put(TOTAL_PROJECT_COST,projectCost);
    contentValues.put(TOTAL_PROFIT,totalProfit);
    contentValues.put(RENTAL_PROFIT,rentProfit);




    long id = db.insert(TABLE_NAME2, null, contentValues);
    return id;


}

我一直在看教程和在线检查，但我似乎看不出我哪里出错了，有人可以帮忙吗？

Answer 1

基本上你没有正确构造你的 sql，这发生在你的长串连接元素中的“每月”附近。

这条sql错误太多了：

INSERT INTO Viewed(repayment monthly,CurrentOffer,Total Purchase
costs,weekly room rate,total refurb cost,Total Money Needed, ...) 

您正在使用空格作为列名。

我有两个技巧可以用来构建更简单的 sql。

1. 首先使用 MySql 客户端，如 Workbench，借助其 GUI 工具更轻松地构建您的表（但要确保数据类型与 Sqlite 兼容）。当查询即将执行时，您可以看到原始 sql，您可以稍后将其复制粘贴到您的项目中。

2. 不要使用这样的字符串连接。使用String.format。

   String sql = String.format(
             "CREATE TABLE %s (%s,%s)",
             TABLE_NAME2,
             UID + " INTEGER PRIMARY KEY AUTOINCREMENT",
             POST_CODE + " VARCHAR(255)");
