Example 2:
Consider a database table called Orders with the following records:
| OrderQuantity | Price | OrderTime |
|---|---|---|
| 100 | 1.58 | 2017-08-18 10:38:42.000004 |
| 120 | 1.61 | The DateTime is 2018-03-23 07:14:16 |
| 125 | 1.78 | 2018-09-12 05:25:56 |
| 50 | 1.80 | 2019-01-16 11:52:05 |
| 200 | 1.72 | 2020-02-06 09:31:34.006789 |
The statement given below can be used to get the time value of records of column OrderTime:
SELECT *, TIME(OrderTime) AS TIME_Value FROM Orders;
This will produce the result as shown below:
| OrderQuantity | Price | OrderTime | TIME_Value |
|---|---|---|---|
| 100 | 1.58 | 2017-08-18 10:38:42.000004 | 10:38:42.000004 |
| 120 | 1.61 | 2018-03-23 07:14:16 | 07:14:16 |
| 125 | 1.78 | 2018-09-12 05:25:56 | 05:25:56 |
| 50 | 1.80 | 2019-01-16 11:52:05 | 11:52:05 |
| 200 | 1.72 | 2020-02-06 09:31:34.006789 | 09:31:34.006789 |
