Case statement in oracle with comparision in Then clause

问题

I am new to using Oracle trying something similar to below code, but unable to accomplish the task.

CASE
WHEN Dimension='abc'
then value=100
When Dimension='def'
then Value between 200 and 300
end

but it is throwing error Missing Keyword state

Please help me to solve this issue

回答1:

You can rewrite your where clause this way.

(Dimension='abc' and value=100)
or 
(Dimension='def' and value between 200 and 300)
