Android E/SQLiteDatabase 上的 SQLite：错误插入日期=05/04/2021 时间=60000.0
SQLite on Android E/SQLiteDatabase: Error inserting date=05/04/2021 time=60000.0
我正在 android studio 上用 Sqlite 创建一个数据库。
这是我的代码：
@Override
public void onCreate(@NotNull SQLiteDatabase db) {
//SQL - Structured Query Language
String CREATE_DATA_TIME_TABLE = "CREATE TABLE " + UtilDB.TABLE_DATA_TIME + "("
+ UtilDB.KEY_DATE + " TEXT PRIMARY KEY,"
+ UtilDB.KEY_TIME + " INTEGER" + ")";
db.execSQL(CREATE_DATA_TIME_TABLE); //creating our table
}
public void addWorkTime(@NotNull WorkTime workTime) {
// if there is just a date, it will update this worktime
if (thereIsADate(workTime.getDate()))
updateWorkTime(workTime);
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(UtilDB.KEY_DATE, workTime.getDate());
values.put(UtilDB.KEY_TIME, workTime.getTime());
Log.d(TAG, workTime.toString());
//Insert to row
db.insert(UtilDB.TABLE_DATA_TIME, null, values); // TODO
Log.d(TAG, "addWorkTime: " + "item added");
db.close(); //closing db connection!
}
但是我有这个问题：

我怀疑您的问题是您更改了 onCreate 方法：-
public void onCreate(@NotNull SQLiteDatabase db) {
//SQL - Structured Query Language
String CREATE_DATA_TIME_TABLE = "CREATE TABLE " + UtilDB.TABLE_DATA_TIME + "("
+ UtilDB.KEY_DATE + " INTEGER PRIMARY KEY," //<<<<<<<<<< WAS THIS
+ UtilDB.KEY_TIME + " INTEGER" + ")";
db.execSQL(CREATE_DATA_TIME_TABLE); //creating our table
}
到
public void onCreate(@NotNull SQLiteDatabase db) {
//SQL - Structured Query Language
String CREATE_DATA_TIME_TABLE = "CREATE TABLE " + UtilDB.TABLE_DATA_TIME + "("
+ UtilDB.KEY_DATE + " TEXT PRIMARY KEY," //<<<<<<<<<< NOW THIS
+ UtilDB.KEY_TIME + " INTEGER" + ")";
db.execSQL(CREATE_DATA_TIME_TABLE); //creating our table
}

但是有 运行 第一个版本，进行了更改，然后 运行 第二个版本没有删除数据库。
DataType Mismatch 仅当尝试 insert/update 行且 rowid 列时才会发生或者 rowid 列的别名不是整数。

column_name INTEGER PRIMARY KEY的特殊之处在于它使通常隐藏的rowid列的列和别名。
见SQLite Result and Error Codes - Result Code meanings
(20) SQLITE_MISMATCH The SQLITE_MISMATCH error code indicates a
datatype mismatch.
SQLite is normally very forgiving about mismatches between the type of
a value and the declared type of the container in which that value is
to be stored. For example, SQLite allows the application to store a
large BLOB in a column with a declared type of BOOLEAN. But in a few
cases, SQLite is strict about types. The SQLITE_MISMATCH error is
returned in those few cases when the types do not match.
The rowid of a table must be an integer. Attempt to set the rowid to
anything other than an integer (or a NULL which will be automatically
converted into the next available integer rowid) results in an
SQLITE_MISMATCH error.
修复
如果您可以承受丢失任何现有数据的简单修复方法是删除数据库，这可以通过卸载应用程序来实现。然后您可以重新运行 应用程序。
如果您有需要保存的现有数据（可能不太可能，因为数据列中的数据可能无用），那么您需要引入一次性 运行，它将：-
- 使用最终的列定义创建一个新的 table，确保 table 的名称不同，例如your_table_NEW.
- 从原来的 table
填充新的 table
- 使用 ALTER TABLE
重命名原来的 table
- 将新的 table 重命名为原来的 table 名称
- 删除新的 table。
