The text of the topic is shown below:

Gentlemen,
I need update a column from another column, like
Code:
update mytable set field1 = field2, field3 = field4*2
I know there is update construction in LiquiBase but I can point constants only, i.e.


Code:
<update tableName="ProductSettings">
<column name="field1" value="field2"/>
</update>

as a result field1's value will be 'field2' string. So how can I point fields and expressions for update?
