在Android SQLite中删除行并只保留最后一个值,可以通过以下步骤实现:
SQLiteDatabase db = this.getWritableDatabase();
String tableName = "your_table_name";
String columnName = "your_column_name";
String condition = "your_condition"; // 设置删除条件
String deleteQuery = "DELETE FROM " + tableName + " WHERE " + columnName + " NOT IN (SELECT " + columnName + " FROM " + tableName + " ORDER BY " + columnName + " DESC LIMIT 1 OFFSET (SELECT COUNT(*) FROM " + tableName + ") - 1) AND " + condition;
db.execSQL(deleteQuery);
上述代码中,你需要将"your_table_name"替换为你要删除行的表名,"your_column_name"替换为你要保留最后一个值的列名,"your_condition"替换为你的删除条件。
db.close();
这样,你就可以在Android SQLite中删除行并只保留最后一个值了。
