奇怪的 SQLite 行为 - 非功能性 UPDATE SQLite 方法
Weird SQLite behaviour - non-functional UPDATE SQLite method
我正在创建一个 Java 桌面应用程序，该应用程序使用具有 50 多个数据变量的 SQLite 数据库。我有一个具有以下变量的 DatabaseHelper class：
//-- The SQLite Database Table name --//
private static final String STAN_RECORDS_TABLE = "STAN_SQLite_Records_Table"; // Primary Table - Table 1.
//-- The STAN Records DATABASE TABLE COLUMNS - or KEYS - defined here as static variables. --//
private static final String STAN_KEY_RECORDS_ID = "Stan_Records_id"; // Record 1
private static final String STAN_KEY_DATE_CREATED = "Date_Created"; // Record 2
private static final String STAN_KEY_EST_TYPE = "Stan_Est_Type"; // Record 3
private static final String STAN_KEY_CITY_TOWN = "City_Town"; // Record 4
private static final String STAN_KEY_LOC_LAT = "Loc_Lat"; // Record 5

private static final String STAN_KEY_CONTACTS_WEB = "Website"; // Record 19
private static final String STAN_KEY_SELF_CATER = "Self_Cater"; // Record 20
private static final String STAN_KEY_PARKING_TYPE = "Parking_Type"; // Record 21
private static final String STAN_KEY_PARKING_SHADE = "Parking_Shade"; // Record 22
private static final String STAN_KEY_PARKING_BAYS = "Parking_Bays"; // Record 23
private static final String STAN_KEY_PARKING_RATING = "Parking_Rating"; // Record 24
private static final String STAN_KEY_SINGLE_UNITS = "Single_Units"; // Record 25

private static final String STAN_KEY_FAMILY_DESC = "Family_Desc"; // Record 30
private static final String STAN_KEY_VIP_UNITS = "VIP_Units"; // Record 31
private static final String STAN_KEY_VIP_DESC = "VIP_Desc"; // Record 32
private static final String STAN_KEY_SINGLE_DOUBLE = "Single_Doubles"; // Record 33
private static final String STAN_KEY_ROOM_COND = "Room_Condition"; // Record 34
private static final String STAN_KEY_ROOM_PRIVACY = "Room_Privacy"; // Record 35
private static final String STAN_KEY_BATHROOM_SHARED = "Bathroom_Shared"; // Record 36
private static final String STAN_KEY_AIR_CON = "Air_Con"; // Record 37
private static final String STAN_KEY_ROOM_FRIDGE = "Room_Fridge"; // Record 38
private static final String STAN_KEY_ROOM_TV = "Room_TV"; // Record 39
private static final String STAN_KEY_ROOM_BEDDING = "Room_Bedding"; // Record 40
private static final String STAN_KEY_ROOM_SIZE = "Room_Size"; // Record 41
private static final String STAN_KEY_BONUS_POOL = "Bonus_Pool"; // Record 42
private static final String STAN_KEY_BONUS_GYM = "Bonus_Gym"; // Record 43

private static final String STAN_KEY_FREE_WIFI = "Free_Wifi"; // Record 58
private static final String STAN_KEY_EST_NAME = "Est_Name"; // Record 59
然后我有一个数据库创建字符串：
//-- STAN Records TABLE creation SQL Statement --//
private static final String CREATE_STAN_RECORDS_TABLE = "CREATE TABLE IF NOT EXISTS " + STAN_RECORDS_TABLE + " (" + /*0*/ STAN_KEY_RECORDS_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "

...和记录插入字符串：

...以及记录更新字符串（这是问题！！）：

所有 SQLite 方法（创建、读取、插入和删除）都运行良好。只是 Update 方法不起作用。它一直执行到显示 JOptionPane 代码...
JOptionPane.showMessageDialog(null, UPDATE_ONE_COMPLETE_STAN_RECORDS_ENTRY);
...甚至显示消息，就好像数据已成功更新一样。但是当您查看要更新的行时，没有任何更改（仍然是原始插入数据）。请帮忙 - 我已经为这段代码苦苦挣扎了一个多星期了。请注意：我对纯 Java 编程还很陌生。我正在使用 IntelliJ IDEA IDE 来开发此应用程序。任何帮助将不胜感激。提前致谢。 Shore-T!
索引 3 被设置了两次。第二次设置时，设置为int。
我正在创建一个 Java 桌面应用程序，该应用程序使用具有 50 多个数据变量的 SQLite 数据库。我有一个具有以下变量的 DatabaseHelper class：

所有 SQLite 方法（创建、读取、插入和删除）都运行良好。只是 Update 方法不起作用。它一直执行到显示 JOptionPane 代码...
JOptionPane.showMessageDialog(null, UPDATE_ONE_COMPLETE_STAN_RECORDS_ENTRY);
...甚至显示消息，就好像数据已成功更新一样。但是当您查看要更新的行时，没有任何更改（仍然是原始插入数据）。请帮忙 - 我已经为这段代码苦苦挣扎了一个多星期了。请注意：我对纯 Java 编程还很陌生。我正在使用 IntelliJ IDEA IDE 来开发此应用程序。任何帮助将不胜感激。提前致谢。 Shore-T!
索引 3 被设置了两次。第二次设置时，设置为int。
