Select records using crystal report with null condition

crystal-reports

Solution

I have found the solution in which the IsNull() field has to comes before the field which is no IsNull().

{vw_CandidateProfile.Type} IN ['NGO','EDU','PRS','PPR','PPS','TTL','OTH'] 
    OR ISNULL({vw_CandidateProfile.Type})

becomes

ISNULL({vw_CandidateProfile.Type})
    OR {vw_CandidateProfile.Type} IN ['NGO','EDU','PRS','PPR','PPS','TTL','OTH']

Problem

I was trying to filter the data in database with the following formula in my crystal report and one of the condition is to included the data even this, '{vw_CandidateProfile.Type}' is null or empty string. But the formula below doesn't work. Any ideas? ``` {vw_CandidateProfile.Candidate_Code} = '881225095228' AND ( {vw_CandidateProfile.Type} IN ['NGO','EDU','PRS','PPR','PPS','TTL','OTH'] OR ISNULL({vw_CandidateProfile.Type}) ) ```
