Hi All,

I have a table with ?only one column?Request_Id char(20) and one data 'jeeva' in that column.

Below are the queries I am using and the corresponding output

1. select * from table_name where Request_Id ?= 'jeeva'

Output: jeeva

2. select * from table_name where cast(Request_Id as char(20)) = 'jeeva'

Output: jeeva

3. select * from table_name where Request_Id like '%a'

Output: No Output

4. select * from table_name where trim(Request_Id) like '%a'

Output: jeeva

5. select * from artemis_app.trim_1

Output: jeeva

My question here is why the 3rd query not able to produce any output... For Char(20) excluding those 5 characters if the remaining ?are filled with spaces it should not return any output for the first query itself...

How is this like operator working for char fields?

Thanks,

Jeeva
