This is an example of a bigger statement but the syntax is the same:
select 2, to_char(UPDATED_BY || '|' || SETTING_NAME || '|' ||SETTING_NAME)
From gsp.settings
I want the distinct UPDATED_BY and SETTING_NAME
I have tried:
select 2, distinct(to_char(UPDATED_BY || '|' || SETTING_NAME) || '|' ||SETTING_NAME)
From gsp.settings
I get this message ORA-00936: missing expression 00936. 00000 - "missing expression"
I also tried this:
select 2, to_char(distinct(UPDATED_BY || '|' || SETTING_NAME) || '|' ||SETTING_NAME)
From gsp.settings
it gets the same error
