| As of MariaDB 10.2 the <code class="code">DATETIME</code> data type supports sub-second fractions. | |
| The default of MariaDB internally is to use no fractions. | |
| The number of fractions can be explicitly set via scale: | |
| <code class="code">@Column(scale=6)</code> will lead to a <code class="code">DATETIME(6)</code> column and able to store microseconds. | |
| A value of <code class="code">@Column(scale=-1)</code> will explicitly turn off all fractions. | |
