# Sort-String-To-SQL
Sort String To SQL For Python 📝
參考 [sortStringToSql](https://github.com/killercup/sortStringToSql) 修改為 Python 版本
* [Youtube Tutorial](https://youtu.be/J8tDVPFiRmk)
## 說明
將 'sort expressions' 轉換成 SQL expressions，方便資料庫 ORDER BY 欄位， E.g. `+id` 會被轉換為 `id ASC`，
因為我目前使用 [MySQL](https://www.mysql.com/downloads/) 居多，所以不同資料庫寫法可能有稍微不同，請在自行修改或 Issuse 給我 :smile:
## 範例
可參考 [sort_string_to_sql.py](https://github.com/twtrubiks/Sort-String-To-SQL/blob/master/sort_string_to_sql.py)
```python
print('+id ->', sort_str_to_sql(sort_expression='+id'))
## +id -> id ASC
print('+id,-name ->', sort_str_to_sql(sort_expression='+id,-name'))
## +id,-name -> id ASC, name DESC
print(' ->', sort_str_to_sql(sort_expression=''))
## ->
```
更多範例可參考 [tests.py](https://github.com/twtrubiks/Sort-String-To-SQL/blob/master/tests.py)
## Test By Case
目前是 by case 寫測試，可參考 [tests.py](https://github.com/twtrubiks/Sort-String-To-SQL/blob/master/tests.py)
請在命令提示字元 ( cmd ) 底下輸入
```python
python -m unittest -v tests
```
output
```cmd
test_case_1 (tests.TestCase) ... ok
test_case_2 (tests.TestCase) ... ok
test_case_3 (tests.TestCase) ... ok
test_case_4 (tests.TestCase) ... ok
test_case_5 (tests.TestCase) ... ok
test_case_6 (tests.TestCase) ... ok
test_case_7 (tests.TestCase) ... ok
test_case_8 (tests.TestCase) ... ok
test_case_9 (tests.TestCase) ... ok
----------------------------------------------------------------------
Ran 9 tests in 0.001s
OK
```
