Splunk Search

Can you help me with a search involving multiple AND conditions in eval w/ if statement?

Hello there from someone in healthcare it industry.

I'm working with multiple conditions, and I want to make sure my syntax is correct here.

| eval goodClaimStat = if((catCode != "E0") and (catCode != "E1") and (catCode != "E2") and (catCode != "E3") and (catCode != "E4") and (catCode != "D0"), "true", "false")
| eval goodEligOrAuth = if(tripleA != "42" and tripleA != "80", "true", "false")
 | eval successTransaction = if((transactionState == "Success" and goodClaimStat == "true" and goodEligOrAuth == "true"), 1, 0)

catCode, tripleA and transactionState are all fields that I extracted from events using rex(). I verified in search that I'm extracting them correctly, so the next part of my query is this decision logic. I'm assuming that this is where my problem lies. transactionState has to be "Success" and then, catCode and tripleA cannot equal those values above, respectively.

No, that is wrong. You must UPPER-CASE your boolean operators, and it is best to use == logic, rather than != logic like this:

... | eval goodClaimStat = if(((catCode == "E0") OR (catCode == "E1") OR (catCode == "E2") OR (catCode == "E3") OR (catCode == "E4") OR (catCode == "D0")), "false", "true")
| eval goodEligOrAuth = if(((tripleA == "42") OR (tripleA == "80")), "false", "true")
| eval successTransaction = if(((transactionState == "Success") AND (goodClaimStat == "true") AND (goodEligOrAuth == "true")), 1, 0)

Notice my extended use of parentheses. This helps because eventually you will be mixing AND, OR, and NOT and it won't work correctly.
