Case conditional when updating data?

[god_prophet]

In order to match a Recipients column, I need to satisfay this conditions:

1.- If customer_cic is length 8, then add 4 spaces at the begging. 
2.- If customer cic is length 12, leave it as it is.


I tried: Case(When(Length(customer_cic)==12,customer_cic, Else('    '+customer_cic)) 

But is giving me error.

Hello @god_prophet 

The correct syntax is:

Case(When(Length(customer_cic)=12,customer_cic), Else('    '+customer_cic))

hi @_Manoj_Kumar_ , I'm getting this error with  that code:

10/17/2023 9:38:07 AM PGS-220000 PostgreSQL error: ERROR: operator does not exist: integer == integer LINE 1: ...cional = case when char_length(W0.sCustomer_cic) == 12 then... ^ HINT: No operator matches the given name and argument types. You might need to add explicit type casts. .

Then I tried: 

Case(When(Length(toString(customer_cic))==12,customer_cic), Else(' '+customer_cic))

But gave me this error.

I request your kindly help.

Ok, this worked: 

Case(When(Length(customer_cic)=12,customer_cic), Else('    '+customer_cic))

Thank you, Manoj.
