如何在liquibase中使用一些默认时间戳更新日期列

Question

How to update date column with default value(2010-01-01 00:00:00) in liquibase. I am know to get the current date. Can you please suggest me to update column with some default value.

 <property name="now" value="SYSDATE" dbms="postgresql">

 <changeSet>
    <update>
      <column name="date_created" valueDate="${now}"/>
    </update>
 </changeSet>

The attribute valueDate supports three formats:

1. YYYY-MM-DD
2. hh:mm:ss
3. YYYY-MM-DDThh:mm:ss

In your case this works:

<column name="date_created" valueDate="2010-01-01" />
